  The field strength of medium and short wave communication system was calculated and correlated for different wavelengths from the predicted local transmitter to different receiving points at different local times by using Vvednsky and Kazantsev method. A correlation constant is formulated that satisfies the relationship between the field strength of medium wave and short wave communication system. It was observed that this correlation constant varies with local time and wavelength. The average value of the correlation constant is maximum at night and minimum at noon. The calculated field strength of short wave communication system is almost the same with the results obtained by using correlation constant.

  Nutrient film technique and sand culture were tested for the year round production of tomato in Bangladesh. Two cultivars of tomato viz., Egg tomato and Kingkong were tested for growth in both winter (November 2000-February 2001) and summer (May 2001-August 2001) seasons in NFT (Nutrients Film Technique) and sand culture. Sand culture was more simple to establish and manage incurved lowed cost compared to NFT system, however higher production was observed in NFT system. Egg tomato was found to be suitable for growth in summer, where as winter was suitable for Kingkong tested NFT and sand culture.

  The experiment was carried out at the orchard of jackfruit research project, Bangladesh Agricultural University, Mymensingh during the period from July 2000 to October 2001 to find out the effect of age of rootstock and time of grafting on the success of epicotyl grafting in jackfruit. The experiment consists of three ages of rootstock viz., 7, 14 and 21 days and seven month of grafting viz., August, September, October of 2000 and April, May, June, July of 2001. It was conducted in randomized complete block design with three replications. Age of rootstock and time of grafting had significant effect on all the parameters studied. The highest success (39.84%), the minimum time required to bud break (18.78 days) and the highest survival (34.41%) were found in 14 days old rootstock. In case of time of grafting, the highest success (49.55%) and survival (45.47 %) and the maximum growth of grafts were observed in the month of June. On the contrary, the lowest success (10.08%) and survival (13.92%) were found in April. The maximum time required to bud break was found in the month of October (24.79 days) while it was minimum in July (20.72 days).The treatment combination of 14 days old rootstock in the month of June produced the highest success (57.33%), the highest survival (53.71%) and the growth of grafts. Therefore, 14 days old rootstock and grafting in the month of June is the best for the propagation of jackfruit through epicotyl grafting.

  In order to produce virus free potato tuber seeds in vitro culture was established using apical meristem of four widely cultivated varieties of Bangladesh namely Diamant, Cardinal, Multa and Lalpakri. Meristem of these varieties of potato were cultured for shoot proliferation and root induction in MS and MS0 medium supplemented with different types and concentration of phytohormones. Among the different growth regulator formulations, 0.5 mg l-1 GA3+0.04 mg l-1 KIN was found to be the best medium for the primary establishment of meristem. The primary established meristems were subcultured on to MSo medium and MS medium containing BA and IBA singly or in combinations. Considering all the treatments singly use of IBA (0.5 mg l-1) is recommended for proper shoot and root development from primary meristem. After DAS-ELISSA test the virus free in vitro grown potato plantlets were using for massive micro propagation. GA3 and KIN singly or in combinations are used for shoot and root multiplication, among all these combinations 2.0 mg l-1 GA3 was found to be the best media for shoot induction for the studied varities. For high frequency of root formation, combination of GA3 (0.1 mg l-1)+KIN (0.1 mg l-1) was most effective. Rooted plantlet were gradually acclimatized and successfully established in the field. Visual evolution of the morphological trials of the tissue culture derived plants showed all plants were found normal and free from virus diseases. Substantial yield increase was observed in meristem derived plants over their source plants.

  A total of 21 four weeks old Nara males divided into 3 groups as A-non-caponized, B-chemically and C-surgically caponized birds having 7 males each. The birds were caponized at 4 weeks of age and reared on individual cages up to 16 weeks of age to assess the body weight gain, hematological traits and blood cholesterol concentration. The weight gain was significantly increased in caponized birds compared to non-caponized birds (p<0.01). However, surgically caponized birds gained the highest body weight. Total erythrocyte count, packed cell volume and hemoglobin concentration were significantly reduced in caponized birds compared to non-caponized birds (p<0.01). Testis weight of group A and B at 16 weeks of age were 19.20 and 2.58 g/bird respectively. The highest enlargement of liver and spleen was found in group-C followed by group-A and B. Adrenal gland weight of A, B and C were 0.14, 0.21 and 0.26g/bird respectively (p<0.01). Reduced comb, wattle and head of caponized birds were observed compared to the non-caponized birds. Caponization is the most suitable technique to have maximum meat from chicken. However, surgically caponization may be the best technique for maximum growth.

  In this experiment the feeds and feeding, production and reproduction profile and herd management of spotted deer were studied in captive condition at Dhaka zoo. Data collected from forty deers, ten deers of each group consisting of adult male, adult female, juvenile and infant were studied January 15th to April 15th 2004 for a period of three months. Available feeds supplied to the spotted deer were maize fodder, para and bucksha grass, poi shak, cabbages, carrot, papaya, wheat bran and soybean meal. Amount of CP and metabolisable energy were 9.8% and 14.24 MJ ME per day, respectively. The average birth weight of males and females were 3.0 and 2.5 kg, adult males and females` weights were 80.44 and 57.6 kg, males and females weaning weights were 19.98 and 18 kg, respectively. It was also observed that the average weaning age, length of estrous, age at first fawning and gestation lengths were 5.02 months, 17.74 days, 14.32 months and 230.74 days, respectively. From the study it may be suggested that keeping balanced nutritive status the productive and reproductive parameters of the spotted deer at Dhaka zoo, recommended rations needs to be followed similarly efficient management systems needs to be developed.

  Production problems of farm machinery are studied in the three major districts namely Dhaka, Comilla and Bogra that play a vital role in supplying farm machinery throughout the country. Most of the manufacturer in the surveyed area has taken farm machinery production as a seasonal business or secondary business due to seasonal demand of farm machinery. Manufacturer gets technical assistance from non-government organizations (NGOs) only. Research stations provided limited range of technical support to the manufacturer. They are not getting financial support from any kind of sources. Production problems are classified as problem before going to production, on going production problem and post-production. Before going to production manufacturer face capital, setting up infrastructure, land, skilled labour, complexity in taking bank loan, political unrest, unhealthy environment, getting electricity connection, bureaucratic complexity and technical know-how of the worker. On going production problems include capital for bulk production, skilled labour, trained technicians, load shedding, double taxation system, raw materials supply, low quality of raw material. Post-production problems are marketing competition with below standard implement of other manufacturer, unauthorized enterprise makes same type of implement of below standard and sold at low price, seasonal demand, ware house, marketing set up, marketing facility. Suggestions in this context are proposed to minimize the problems of producing farm machinery in the country.

  A study was undertaken to determine the arsenic status of some selected soils in six thanas of three arsenic affected districts of Bangladesh. Eighteen soil samples taking three from each of 6 thanas representing 3 districts viz. Moulavibazar, Habiganj and Sylhet of Bangladesh were collected for the study. The soils were collected from 3 depths viz. 0-15, 15-30 and 30-45 cm from each location. The arsenic content in soils of Moulavibazar, Habiganj and Sylhet districts ranged from 1.32-31.89, 0-16.87 and 0.66-17.57 ppm, respectively. Out of 18 samples, arsenic content was noticed for 11 samples at 0-15 cm depth (1.98-25.76 ppm), 15 samples at 15-30 cm depth (3.96-30.68 ppm) and 14 samples at 30-45 cm depth (3.96-38.23 ppm). The highest arsenic content of 38.23 ppm was found at 30-45 cm depth in Sylhet district. Seven samples at 0-15 cm, 3 samples at 15-30 cm and 4 samples at 30-45 cm were free from arsenic contamination. Correlation study of arsenic contents of soils was done with some soil properties viz. sand, silt and clay contents, soil pH, EC and organic matter status. Results showed that arsenic content correlated significantly with different soil properties.

  The study was carried out to identify resistant rootstocks of Solanum species for grafting of cultivated eggplant varieties against root-knot nematode and to evaluate the grafting compatibility of eggplant varieties with wild Solanum root-stocks. Three experiments were conducted in this respect. Six wild Solanum root-stocks were screened against root-knot nematode (Meloidogyne incognita). The root-stocks Solanum torvum and Solanum sisymbriifolium showed resistant reaction against root knot nematode. Fourteen varieties/genotypes were screened against root-knot nematode among which six varieties/genotypes showed resistant reaction. Three cultivated eggplant varieties viz., Sufala, Singnath and Kazla were grafted on Solanum torvum and Solanum sisymbriifolium. The highest grafting success was 95% in case of Solanum torvum with Sufala and the lowest (85%) in Solanum sisymbriifolium with Singnath. The success of grafting was not affected significantly due to the effect of scion and or of root stocks. The grafted plants showed resistant reaction against the disease while the scion plants showed susceptibility in the sick beds. The grafted plants also showed resistant reaction against the disease in the field conditions. The grafted plants also outyielded compared to the scion plants. The grafting combination Solanum torvum with Sufala gave the highest yield compared to other grafting combinations and non-grafted plants.

  The study was conducted to determine the effect of seed cleaning and washing on the incidence of bacterial leaf blight (BLB) of rice cv. BR11. Six different treatments were used. They were farmer`s seeds clean seeds, diseased seeds, farmer`s seeds washed with tap water, farmer`s seeds washed with 20% brine solution and clean seeds washed with tap water. Three seed health testing methods namely paper rolled towel, cassette slide holder and liquid assay method were used for detection of BLB infection in seed. Seed health both before sowing and freshly harvested seeds from six different treatments were determined. Seedling vigour of clean seeds and brine solution washed seed were also higher than farmer`s seed and diseased seed. Xanthomonas oryzae pv. oryzae was identified through physiological, biological, serological, hypersensitive reaction and pathogencity tests in seeds of all treatments. Incidence of BLB in field plots were recorded at tillering stage and flag leaf stage. Maximum and minimum BLB disease was recorded in diseased seeds and brine solution washed seeds respectively for both situation.

  Study was conducted to gain a better understanding on the impact of tiger attacks on people by tigers from the Sundarbans as well as different zoo in Bangladesh. From the study it was observed that the highest number of tiger attacks occurred in Shatkhira and lowest in Khulna range, the largest concentration (94%) of attacks took place between 10-12 AM and least (10%) at 9 PM to 3 AM as well as it is clear that people in the age group 15-29 are the least vulnerable, while people that are 60 or over are much vulnerable to tiger attacks, where as Mawalis are the most (51%) as well as Bawalis are the second most (20%) vulnerable to tiger attacks. From the study it also appears that 52% of the victim’s are attacked during collecting fuel wood, timber or other raw materials and around 20% of the victim’s are found during fishing, among them 68% of the victim’s suffered from their decrease income and expenditure and around 28% of the victim’s suffered from stopping their income source. From the study it is concluded that an awareness campaign and motivation is needed as well as diversified income stability to create for the victim’s in the Sundarbans.

  A field experiment was conducted to evaluate the performance of wheat varieties as an understory crop of different multipurpose tree species at the Agroforestry Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during November 2005 to March 2006. Five wheat varieties such as Gourove, Sourove, Shotabdi, Kanchan and Protiva were cultivated as an understorey crop of three different tree species such as Albizia lebbeck, Psidium guajava and Mangifera indica. The experiment was laid out in split plot design with three replications where tree species were in main plot and wheat varieties were in sub plots. All the tree species were statistically indifferent in their effect on grain yield. However, the highest yield (2.60 t ha-1) was found under Albizia lebbeck followed by Mangifera indica (2.58 t ha-1) and Psidium guajava (2.53 t ha-1). The trees species at their early stages of growth had a very little impact on the associated wheat crop except that crops grown in close proximity with tree lines suffered around 11-13% yield reduction. Among the wheat varieties, Shotabdi produced the highest grain yield (2.88 t ha-1) and total dry matter followed by Gourove and Shourove. Therefore, it can be suggested that farmers in the northern region of Bangladesh may cultivate wheat variety Shotabdi as an understory crop of Albizia lebbeck during its early years of establishment.

  Resistant rootstock of six Solanum species and 21 cultivated eggplant varieties were identified against bacterial wilt and the graft compatibility of eggplant varieties was studied with wild Solanum rootstocks. Solanum torvum and Solanum sisymbriifolium showed resistance against bacterial wilt. Most of the cultivated varieties showed susceptibility against bacterial wilt. Three cultivated eggplant varieties viz. sufala, singnath and uttara were grafted on Solanum torvum and Solanum sisymbriifolium. The highest grafting success was 95% in case of Solanum torvum x sufala and the lowest 85% in Solanum sisymbriifolium x singnath. The success of grafting was not affected significantly due to the effect of scion and rootstocks. The grafted plants showed resistance against the disease while the scion plants showed susceptibility in the sick beds. The grafted plants also showed resistance reaction against the disease in the field conditions. The fruit maturity was delayed due to grafting but grafting at least 15 days prolonged the harvesting period. The grafted plants also out yielded the scion plants. The grafting combination Solanum torvum x sufala gave the highest yield compared with other grafting combinations and non-grafted plants.

  Genetic variability was studied for eight quantitative traits in fourteen parental lines of hybrid rice. The characters were plant height, flag leaf initiation day, first panicle initiation day, days to 100% flowering, days to maturity, grain yield/10 hills, spikelet fertility/10 panicles and no. of effective tillers/hill. Two additional characters (flag leaf length and spikelet length) were included in heterosis study. In general high component of variation and coefficient of variability were observed for most of the characters. The highest component of variation, coefficient of variability and heritability were noticed in grain yield/10 hills. Characters those with high genetic variability and genetic advance were considered to be important for selecting the desirable lines. Heterosis was studied in ten F1 lines for 10 characters. In general, the hybrids performed significantly better than the respective parents. Mid parent, standard variety and better parent heterosis were observed for all the characters under study. In comparison of F1 hybrids with their respective mid parent, standard variety and better parent showed significant heterosis for most of the studied characters. Among the 10 hybrids three lines viz., IR62829AxIR62036-222-3-3-1-2R, IR58025AxIR61614-38-19-3-2R and IR68888AxIR56381-139-2-2R exhibited the highest heterosis in grain yield/10 hills. In conclusion, there was an ample scope for developing suitable hybrid rice from the studied parental lines as the hybrids exhibited vigour and earliness.

  Bee plants grown in and around Bangladesh Agricultural University campus were identified on the basis of the frequency of visits by the worker bees to the flowers of these plants. All together 29 bee plants were identified in "honey flow season" (December to March). Nine of these plants did not provide pollen and five of them did not provide nectar. Bee plants were 34 in number in "dearth period" (April to July). Of these, 15 plants did not provide pollen and 12 did not supply nectar. Only four bee plants were identified in "extended period" (August to November). Most of them provide only pollen. There were five bee plants, which provide pollen and nectar throughout the year. It was found that on an average drumstick honey contained the highest moisture (26.48%) followed by mustard (25.72%) and black berry (21.94%). The lowest moisture (18.50%) was found in litchi honey. Highest and lowest reducing sugars were obtained in mustard honey and blackberry honey. On the otherhand, litchi honey contained highest (5.50%) non-reducing sugar and mustard honey contained the lowest (4.69%). Total sugar was the highest (72.70%) in mustard honey followed by litchi (70.20%). Ash content was highest (0.54%) in Drumstick honey followed by blackberry and litchi honey.

  Organoleptic, microbiological and biochemical qualities of four dried fish samples (Mugil cephalus, Scoliodonshorrakowah, Harpodon nehereus and Setipinna phasa) were assessed in summer and winter season and their qualities were compared. The organoleptic score of the samples collected in winter were higher than summer season. The standard plate count (SPC) of different samples in summer and winter indicated an acceptable microbial load. Total Coliform (TC) counts of the samples in summer and winter were found to vary between <3 MPN g-1 to 4 MPN g-1 and had no differences except for Mugil cephalus (4 MPN g-1 in winter) and Harpodon nehereus (4 MPN g-1 in summer). Total Coliform (TC) counts of rest of the samples were <3 MPN g-1. The faecal coliform counts of all the samples were also <3 MPN g-1. Vibrio and Salmonella were not detected in any of the four samples. A slight variation was observed in moisture, ash, protein and fat content of the samples in summer and winter. Moisture, ash, protein and fat content of Parshe were higher in summer. In case of Mugil cephalus and Scoliodon shorrakowah, TVB-N was higher in winter than summer. TMA-N content of the two species (Mugil cephalus and Scoliodon shorrakowah) showed a similar pattern to that of TVB-N. TVB-N and TMA-N content of the remaining two species i.e. Harpodon nehereus and Setipinna phasa showed a reverse pattern in comparison to Mugil cephalus and Scoliodon shorrakowah. Mugil cephalus and Harpodon nehereus showed higher pH in winter than summer while, the pH in Scoliodon shorrakowah and Setipinna phasa was higher in summer.

  Milk samples from single, twin and triplet or 1st, 2nd and 3rd lactation bearing Black Bengal goat were collected to monitor the physical (organoleptic, specific gravity and pH value) and chemical (acidity, fat, SNF, total solids, protein, lactose and ash content of milk) quality of milk. From the above tests, it was observed that the color, flavor, taste and texture of milk samples were normal; yellowish white, normal (goaty), slightly sweet and free flowing liquid. Except acidity and protein content, all other chemical traits varied significantly among different kid bearing goats milk. Chemical parameters were similar in different lactations except fat and total solids percentage. Results of the above experiments indicated that milk obtained from single kid bearing and 2nd lactating goats were better than the other number of kids bearing or lactating goats

  The nature and extent of damage of shoot borer, Hypsipyla robusta (Moore) Lepidoptera: Pyralidae was studied in 2-8 years old Chukrasia velutina Wight et Arn. plantations in hilly areas of Chittagong, Bangladesh. A single tree could have attacked several times in the season. About 47% C. velutina trees were found to have attacked at least once in their lifetime. The infestation rate was more pronounced on the hill slopes (56%) than on the valleys (37%). A good number of trees (60%) were found to exhibit recovery trend after the infestation while other trees were with the formation of fork, cork, knot, curve, twist, whorled branching from the point of infestation (Mostly at a height of 2-3 m). It was estimated that about 42% potential biomass production was lost due to the infestation. Apart from that, some trees were found to show an encouraging `resistance` character keeping intact themselves against the infestation that referred an ample scope of propagation and plantation in future for a better inheritance.

  Genetic variability and heterosis for eight quantitative traits were evaluated in seven parents and ten hybrids. The hybrids were derived from a 5x2 line x tester mating design. In general high component of variation and coefficient of variability were observed for most of the characters. The highest component of variation, coefficient of variability and heritability were noticed in PW, TW 60 and TN 60. Characters those with high genetic variability and genetic advance were considered to be important for selecting the desirable parents. Heterosis was worked out over mid parent, better parent and standard parent. Combinations AU/13, LP/13, PT/13 and LS/13 for PH; combination PT/13 and LP/13 for TN 60 were significant for mid parent, better parent and standard parent heterosis. The best heterotic combinations for TW 60 were LP/13, LS/13 and LSB/13 which recorded 990.28, 1115.28 and 648.61% standard heterosis respectively and can be utilized for hybrid development.

  A sand culture experiment was carried out during 2002-2003 to evaluate the effect of different levels of salinity on some metabolic activities and yield of three mustard genotypes viz., Safal, Binasarisha-4 and Binasarisha-5. The salinity treatments were EC0 (control or no salt), EC5, EC10 and EC15 dS m-1. Results reflected that salinity treatment caused decrease in NR activity and reduced the accumulation of chlorophyll, nitrate, amino acid, soluble protein and sugar. Root volume and weight and the accumulation of potassium and zinc were decreased while nitrogen, phosphorus and sodium accumulations increased. Genotypes Safal and Binasarisha-5 had higher accumulation of almost all the biochemical and chemical substances compared to Binasarisha-4 at salt stress condition. In all the genotypes of mustard yield was reduced at salt stress condition. But in genotype Safal dry matter accumulation and seed yield were better than those of the other two. From the above results it was indicated that Safal and Binasarisha-5 performed better with respect to biochemical point of view as well as yield under salinity stress.

  The present study was assigned to determine the present status including general information, feeding breeding housing milking etc. and costs & returns of small dairy farms, to compare the productive and reproductive performance of crossbred and indigenous cows and to make recommendation for development of small scales dairy farm. With this view, the empirical data were collected by using protested questionnaire. The study was conducted at 8 thanas in Rangpur district, and four months-long survey was diminished on thirty small dairy owners. It appeared from the study that 57% farm owners belong to business class and remaining 43 per cent to different categories. Fifty three per cent took dairying as a side-business whereas only 47 per cent took it as a main business enterprise. Major percentage of farm owner education level that was Higher Secondary level (60%) and the average number of animal per farm was 13.01. The average monthly income of farm owners found in the study area was Tk. 4387. It was observed that farm owners had 85.4% crossbred (like Friesian cross and Jersey cross) and was 14.6% indigenous cattle, and 87% farmers used artificial insemination and rest used both artificial and natural services. Daily milk yield/cow/farm was 4.27 and 1.78 liters for a crossbred and indigenous dairy cow, respectively. It was estimated that the rearing cost of dairy cow was Tk. 67.5/cow/day and return from rearing dairy cow was Tk. 85.2/cow/day. The net return was Tk. 17.7/cow/day from crossbred in the study area and cost benefit ratio was 1: 1.26. The study showed that there were significant (P<0.01) differences within the dry period, service per conception, calving to first service, highest and lowest milk production and lactation period of crossbred and indigenous dairy cows. The study also showed non-significant differences within calving interval for crossbred and indigenous. Incase of small dairy farming, the farms were facing a lot of problems such as scarcity of feeds and fodder, high price of concentrate and lack of technical knowledge. Although the dairy cow owners face problems, the study observed that there were potentials particularly for the small dairy farmers. The small farmers by keeping 8-10 crossbred cows could earn a modest living by adopting small dairy farming as a profession.

  The study was conducted at Bangladesh Agricultural University Dairy Farm for a period of six months. A total of 164 dairy cows belongs to different breeds, such as Jersey cross, Sahiwal cross, Sindhi cross, Holstein cross and Red Chittagong cows were selected and their information regarding milk production and other reproductive parameters were collected from farm records for a period of last five years (1993-1997). The number of animals of each of the genotypic classes were 48 for Jersey cross, 46 for Sahiwal cross, 35 for Sindhi cross, 20 for Holstein cross and 15 for Red-Chittagong. Significant difference was found within the milk yield (p<0.01), calving interval (p<0.05) and birth weight of calves (p<0.01) of different types of dairy cows. In case of lactation length, gestation length and service per conception, there were no significant differences (p>0.05). Highest milk yield (3.20 lit/day), highest birth weight of calves (15.2 kg) and lowest calving interval (414 days) were observed for Holstein cross. The lowest milk yield (2.46 lit/day) and lowest birth weight of calves were found in Red-Chittagong cows. Production performance of Holstein crossbred were superior to other dairy crossbreds. Jersey crossbred ranked second and performances of other genotypes were nearly similar.

  Market diseases of banana were surveyed in three markets of Mymensingh town. Anthracnose and botryodiplodia rots were detected as the main cause of market rots of banana fruits. About 2.04-4.90% fruits were rotted during April-September due to anthracnose and 2.96-4.74% owing to botryodiplodia rots. Both the diseases clearly correlated positive with temperature. The causes of anthracnose and botryodiplodia rots were identified as Colletotrichum musae and Botryodiplodia theobromae, respectively.
