  To find out the diseases occurring in cockerels and its relationship with the management of cockerel`s farm an investigation was carried out from day-old chicks up to marketing at three different cockerel farms in Mymensingh district. In the farm 1, IBD appeared at the age of 31-35 day, the morbidity being 100% and mortality 28.57%. Vaccination at high environmental temperature and use of no fumigation, might be the managemental factors contributed in the causation of the malady. In the farm 2, the morbidity and mortality of yolk sac infection, hypovitaminosis-E, coccidiosis and miscellaneous condition were recorded 3.6 and 2.4%; 4.4 and 2.0%; 8.4 and 0.8%; 0.4 and 0.4%, respectively. However, litter management problem and problem in maintenance of optimum temperature in the shed might be related to these maladies. In the farm 3, the morbidity and mortality rates of the diagnosed diseases like IBD and hypovitaminosis E were 8.6 and 1.4%; 1.2 and 0.4%, respectively. The proportionate mortality of cockerels in these farms were 81.6% for IBD, 8.04% for hypovitaminosis E, 6.89% for yolk sac infection, 2.29% for coccidiosis and 1.14% for miscellaneous condition. IBD occurred in age group of >2-8 weeks, hypovitaminosis E in 0-2 and >2-8 weeks group, yolk sac infection in 0-2 weeks, coccidiosis in >8-20 weeks and the miscellaneous condition in 0-2 weeks group. The findings indicate that IBD is the major disease problem in cockerel farming in Mymensingh.

  An attempt has been undertaken to evaluate the humoral immunity against Newcastle disease in vaccinated chickens. Two different vaccination schedules were followed in 4000 Bovans White chickens (2000 in each treatment) with the history of ND vaccination in parent stock. The mean HI antibody titres of control groups of Treatment-1 and Treatment-2 revealed day-1 (285.51 and 289.43), day-5 (145.74 and 143.78), day-10 (73.58 and 71.47), day-15 (34.44 and 34.52) and day-20 (18.65 and 17.14) respectively. Birds of treatment-1 were vaccinated at 10 and 24 days old with live ND clone-30 vaccine and at 31 (half dose) and 120 (full dose) days old with oil adjuvant inactivated vaccine. Birds of treatment-2 were vaccinated at 10, 24 and 60 days old with live ND clone-30 vaccine and at 120 days old with oil adjuvant inactivated vaccine (full dose). The mean HI antibody titres for vaccinated groups of Treatment-1 and Treatment-2 revealed at day-10 (69.71 and 70.39), day-24 (19.73 and 24.34), day-31 (57.85 and 53.72), day-60 (251.52 and 76.34), day-120 (50.30 and 26.28) and day-150 (442.71 and 371.80) respectively. Vaccination program used in Treatment-1 gave better humoral immune response than in Treatment-2.

  Varieties Rai-5, Shambal and Daulat of Brassica juncea and varieties Barisarisa-7 and Barisarisa-8 of Brassica napus were tested for yield and component characters under different levels of soil salinity. The variations due to salinity levels, varieties and variety-salinity (interaction) were significant for different characters. The variable degrees of increase and decrease of regression coefficient estimates (curve estimation) indicated the performance as influenced by different salinity levels. The performance of the variety Barisarisa-7 in plant height and days to first flowering is the best followed by Barisarisa-8 and Daulat. Barisarisa-8 showed the best performance in days to maturity followed by Barisarisa-7 and Shambal. Shambal followed by Daulat and Barisarisa-7was performed incase of number of siliqua per plant. Daulat performed better than others incase of seed per plant and seed yield per plant followed by Rai-5. Considering all the characters the most tolerance ability was found in Daulat under B. juncea and Barisarisa-7 under B. napus which were followed by Barisarisa-8 of B. napus against different levels of salinity.

  The arsenic status of some selected soils was determined in ten thanas of four arsenic affected districts of Bangladesh. Thirty soil samples taking three from each of 10 thanas representing 4 districts viz. Gopalganj, Faridpur, Rajbari and Madaripur of Bangladesh were collected. 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 Gopalganj, Faridpur, Rajbari and Madaripur districts ranged from 3.96-25.09, 0-38.67, 1.32-36.99 and 1.32-38.19 ppm, respectively. Out of 30 samples, arsenic content was noticed for 21 samples at 0-15 cm depth (1.98-46.09 ppm), 26 samples at 15-30 cm depth (1.98-51.73 ppm) and 27 samples at 30-45 cm depth (1.98-54.05 ppm). Nine samples at 0-15 cm, 4 samples at 15-30 cm and 3 samples at 30-45 cm were free from arsenic contamination. On the other hand, 7 samples at 0-15 cm depth, 6 samples at 15-30 cm depth and 4 samples at 30-45 cm depth were found to be slightly arsenic contaminated. 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.

  An experiment was conducted to study the estimate of total biomass (shedded leaves plus roots) during bast fibre crop (jute, kenaf and mesta) cultivation and the performance of biomass in soil fertility. The newly released four varieties of Bangladesh Jute Research Institute were used in the trial viz. Deshi jute BJC-83, Tossa jute OM-1, kenaf HC-95 and mesta HS-24. Each of the new variety produces good amount of biomass and enriches the soil fertility. The highest biomass produced with HC-95 (7.30 t ha-1) and lowest BJC-83 (5.23 t ha-1). Appreciable performance recorded with each of the variety in enriching the soil fertility on post harvest soil. Highest organic carbon (1.31%) nitrogen (0.13%) phosphorus (18 ppm) and potassium (0.183 meq/100) were found with the variety HC-95. The percent increment of organic carbon (OC), nitrogen (N), phosphorus (P) and potassium (K) by the HC-95 were 87.14, 150.00, 63.64 and 30.71 respectively over the initial soil nutrient content. According to the performance of the production of biomass and soil enrichment the varieties were in the order of HC-95> HS-24> OM-1> BJC-83.

  A field experiment was conducted to study the effects of S, Zn and B supplied from chemical fertilizers and poultry manure on yield and nutrient uptake by rice (cv. BRRI Dhan-30). There were ten treatments:- T0, T1, T2, T3, T4, T5, T6, T7, T8 and T9. The rate of different nutrients were 100 kg N ha‾1 from urea, 30 kg P ha‾1 from TSP, 60 kg K ha‾1 from MP, 20 kg S ha‾1 from gypsum, 2 kg Zn ha‾1 from zinc oxide, 1 kg B ha‾1 from borax and 4 t poultry manure ha‾1. The experiment was laid out in randomized complete block design with 3 replications. The different nutrients significantly increased plant height, effective tillers hill‾1, filled grains panicle‾1, 1000-grain weight, grain and straw yields of rice. The highest grain yield of 4850 kg ha‾1 was obtained when S, Zn and B were applied together with NPK fertilizers (T8) which was comparable to the yields obtained when S, Zn or B were applied singly or in combination of two with NPK fertilizers (T2, T3, T4, T5, T6 and T7) and also with the application of poultry manure with reduced NPK application (T9). The concentrations and uptake of N, P, K and S by grain and straw were higher when poultry manure was used as a source of S, Zn and B with reduced amount of NPK(T9). It appears that application of S, Zn and B along with NPK is essential in this soil to get maximum yield of BRRI Dhan-30. If poultry manure can be applied @ 4 t ha‾1 the use of NPK can be reduced and S, Zn and B fertilizers may not be needed.

  The study was conducted to determine the effect of grafting on the growth, yield and control of wilt disease of watermelon. Grafting of watermelon on bottle gourd root stock significantly reduced the wilt disease in the field. Grafting also produced higher number of fruits per plant (5.25) and larger fruit (30.30 cm) which ultimately produced higher yield (56.92 t/ha‾1) than non grafted plants. The grafts produced 3.5 times higher yield than non grafts.

  An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University Farm, Mymensingh during the Aman season of 1999 to evaluate the effect of manures and fertilizers on the growth and yield of BRRI Dhan 30. The experiment was laid out in Randomized Complete Block Design with three replications. There were seven treatments such as T0 (control), T1 (N100), T2 (N100S10Zn5), T3 (PM5), T4 (PM7.5), T5 (PM10) and T6 (CD10). The results demonstrated that all the treatments had positive effect on the yield components and yields of BRRI Dhan 30. Grain and straw yields of BRRI Dhan 30 were significantly increased due to different treatment and the highest value was recorded with the application of poultry manure at 10 t ha -1. The NPKS content in BRRI Dhan 30 and their uptake were increased due to the application of manures and fertilizers. Analysis of post-harvest soils revealed that organic manure application had a positive influence on organic matter, total N, available P, exchangeable K, available S and CEC of the post-harvest soils.

  Two identical field experiments were conducted, one in Phulpur, Mymensingh and the other in Netrokona during rabi season of 1999-2000 to evaluate the effect of boron on the growth and yield of mustard and to find the suitable dose of boron fertilizer for mustard in Old Brahmaputra Floodplain soil of Bangladesh. Four treatments such as T0 – Control, T1 – recommended package, T2 – alternate package and T3 – farmers’ practice were applied Application of boron significantly influenced plant height, branches per plant, pods per plant, seeds per pot, 1000-seed weight, seed yield and stover yield of mustard. The highest seed yield was obtained with the application of 1.5 kg B ha -1 in association with site specific recommended doses of N, P, K, S and Zn fertilizers in both Phulpur and Netrokona locations.

  Fifty-six genotypes composed of BR, IR and rice-wheat back cross (RWBC) derivatives were evaluated at the DSR drought prone area of Chuadanga. Five genotypes viz. BR5543-5-1-2-4, BR5742-B-15-3-7-2, BR5943-B-10-1-1, BR6058-6-3-3 and IR56463-184-2-1-2 had drought recovering ability. In addition, these lines were grown 6-13 days earlier than the local variety with resistance to lodging. Although, Fulbadami (Local) had significantly longer root length potential than the above genotypes but BR21 showed significantly shorter root system than BR6058-6-3-3 and BR5543-5-1-2-4. Furthermore, BR6058-6-3-3 required significantly longer time for complete leaf rolling than Fulbadami and BR5543-5-1-2-4 was similar to the checks. Again, BR6058-6-3-3 and BR5543-5-1-2-4 showed significantly higher yields (4.0-4.1 t/ha) than Fulbadami (3.2 t/ha) and BR21 (3.1 t/ha). The yield contributing characters of these lines increased significantly over the checks. BR5543-5-1-2-4 and BR6058-6-3-3 therefore, were identified to be the promising genotypes for drought-prone DSR area.

  Seven varieties of Brassica campestris were tested for germination percentage, days to germinate and plant height under different salinity levels of soil. The variations due to salinity levels, varieties and variety x salinity were significant for different characters. The regression coefficient estimates (curve estimation) indicated variable degrees of increase or decrease in performance as influenced by different salinity levels. The performance of the variety Safal in germination percent is the best followed by Tori-7, Sampad and Kallyania. Safal showed the best performance in days for germination followed by Sonali, Sampad and Dholi. Dholi and Sonali performed better than others in respect of plant height. Considering all the characters the performance of Sonali, Sampad and Dholi is much better than others against different levels of salinity.

  The effect of protein supplementation was studied on growth and reproductive performance in female goats and sheep under grazing condition. Ten does and six ewes aged about 15 months and weighing on average 13.9 and 14.4 kg respectively were studied for 112 days. Animals were allocated to two feeding regimes [low protein (LP), 168g and high protein (HP), 208g per kg DM] according to live weight. Supplemental feed contained wheat bran, rice polish and soybean meal (LP-43: 43:14 & HP-35: 35:30, 300 g/d). HP diet non significantly (P>0.05) decreased the DM intake in goats. Moreover, significantly (P<0.05) increased live weight gain was observed in goats receiving HP diet. In contrast, sheep receiving the HP diet significantly (P<0.05 to P<0.01) improved DM intake and live weight gain compared with those given LP diet. Average birth weight of kids (0.85 vs. 0.75 kg) and lambs (1.10 vs. 0.83 kg) were higher in both species that received the HP diet than those given the LP diet. Subsequently daily average live weight gain in kids received the HP diet was higher (62.4 vs. 45.4 g/d) than those fed the LP diet up to weaning. These results showed that the effect of supplementing high protein to grazing improved the growth and reproductive performance of goats and sheep.

  The present study examines the consumption pattern of milk and milk products among different income groups in some selected areas in Bangladesh. Family budget data were collected through household survey during September` 01 to May 2002 for 179 selected households from the three different areas of Bangladesh, comprising 44 from Rural, 61 from Municipality town and 74 from Metropolitan city households formed the basis. The sample households were post classified into 5 income groups based on monthly household income as follows: (I) < Tk. 3000; (II) Tk. 3001-6000; (III) Tk. 6001-9000; (IV) Tk. 9001-12000 and (V) >Tk. 12000. Among milk and milk products, the major allocation of expenditure was devoted to liquid milk followed by sweetmeats and powder milk and `other milk products`. The municipality town households consume more milk, sweetmeats and dahi than Rural and Metropolitan city. On the other hand, Metropolitan households consume more powder milk, condensed milk, ghee and ice cream. Milk and some milk products consumption and expenditure on it increased substantially, with the increase of income in all the areas.

  Sixteen hybrid varieties/lines viz. Sonar Bangla-1, Sonar Bangla-5, Sonar Bangla-6, Sonar Bangla-12, 262H, 283H, 284H, 287H, 291H, 305H, 306H, 311H, 312H, 317H, 321H, 352H and check variety BR28 were evaluated under natural epiphytotics against Bipolaris oryzae to find out the effect of brown spot on their yield and yield contributing characters. The hybrid line 321H showed highest disease incidence (80%) and severity (77%) followed by 352H, 305H, 291H and Sonar Bangla-5. The lowest incidence (40.50%) and severity (45%) were recorded in case of hybrid line 312H followed by 287H, 284H and 283H. Eventually, 312H performed the highest yield (6.88 t ha-1) and the lowest (3.54 t ha-1) was in case of 321H. Yield contributing character like number of effective tillers/hill, panicle length, number of grains/panicle were significantly higher in 312H while number of spotted grains and unfilled grains/panicle were significantly higher in 321H. Disease incidence and severity were correlated significantly and negatively with the yield.
