  The experimentation was made to investigate the incidence of tomato yellow leaf curl virus and its effect on the nutritional components in fruits and chlorophyll content in the leaves of Lycopersicon esculentum taken under phytopesticidal management. Phytopesticidal treatments used in the study were extracts of neem (Azadiracta indica) fruits, garlic (Allium sativum) bulbs, karamja (Pongamia pinnata) leaves and mehogoni (Swietenia macrophylla) seeds. Plots with no phytopesticidal treatments were used as control. Plants under no management were found to be in highest incidence of the virus. There were significant role of phytopesticides in reducing the incidence and severity of tomato yellow leaf curl virus. Among the treatments, Karamja extract performed best against TYLCV in all respect of yield and yield related parameters of tomato. Viral infection in tomato plants caused a negative effect on fruit nutrition. Though negative effect of TYLCV infection was found for chlorophyll A content in tomato leaves, but for chlorophyll B, it caused no significant effect.

  The experiment was conducted in the net house and laboratory to determine the effectiveness of two insecticides viz., Cymbush (Cypermethrin) and Brifer (Carbofuran) on brown plant hopper, Nilaparvata lugens and the toxic action of these insecticides to the predators lady bird beetle, Micraspis discolor and wolf spider, Lycosa pseudoannulata. Effectiveness of the insecticides was assessed on the basis of percentage of corrected mortality of brown plant hopper, lady bird beetle and wolf spider under laboratory condition at 24, 48 and 72 h after treatment. Cymbush 10EC @ 0.05 kg a.i. ha-1. caused 100% mortality of insect populations at different time intervals. All the doses of Brifer 5G caused a good mortality of N lugens at different time intervals and was effective at higher dose. Cymbush 10EC @ 0.04 kg a. i. ha-1. and Brifer 5G @ 0.5 kg a.i. ha-1. were found very effective against N. lugens. The effectiveness of Cymbush 10EC decreased and Brifer 5G increased with increasing time interval. Cymbush 10EC @ 0.05 kg a.i. ha-1. was highly toxic and 0.01 kg a.i. ha-1. was less toxic to both the predators. Brifer 5G @ 0.5 kg a.i. ha-1. was least toxic to the predators. Between the two predators L. pseudoannulata was more susceptible to the insecticides than M. discolor.

  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.

  The study was conducted to analyze the responses of two tomato varieties, BARI tomato-4 and BARI tomato-6 to different environments. The environment used in the experiment were no mulch or control (E0), straw mulch (E1), black polythene mulch (E2), water hyacinth mulch (E3) and am-ada leaf mulch (E4). There were significant influences of different mulches on the growth and yield of tomato. The height of plant, number of leaves, number of main roots, length of roots, fresh and dry weight of roots, number of flower and fruit clusters, number of fruits per plant, weight of fruits and fruit yield per hectare were significantly higher under the environment provided by black polythene mulch. There were also variations in yield contributing characters between the varieties. BARI tomato-6 produced higher yield (55.16 t ha 1) than BARI tomato-4 (51.8 t ha 1). Among the variety-environment combinations the highest yield (61.18 t ha 1) was produced by BARI tomato-6 under the environment of black polythene mulch. This combination also gave the best economic return (BCR = 4.52).

  The present investigation was carried out to study the comparative efficacy of two medicinal plant extracts and an antibiotic on wound healing. This was conducted on 18 female goats at BAU Veterinary Clinic. Infiltration anesthesia was performed with 2% lignocaine hydrochloride (Jasocaine®, Reneta Pharmaceuticals Ltd.) at the site of operation on lumber region. Four experimental skin wounds, two in either side of the midline plane at the lumbar region were made, each was of 2.5 cm length and 0.5 cm depth. The experimental animals were studied under 6 Groups. A series of 50 and 30% extracts of border plant (Aerva sanguinolenta), thankuni plant (Centella asiatica), antibiotic (Pronapen®) and saline were used in this experiment and these were applied twice daily to each wound. All extracts seemed to be effective for rapid healing. A 50% extracts of border plant showed the best result where healing time was 14 days whereas in antibiotic it took 16 days. In contrast more time (20 days) was required for control group. Clinical feature revealed exudation, scab formation, redness and other routine changes. Redness was more prominent in control and antibiotic treated groups compare to other groups on day 3 of wounding. Thus both border and thankuni plant extracts are very much effective for wound healing and can be applied instead of antibiotic.

  Rossomalai is a delicious and famous sweetmeat of Bangladesh. But till now the product lies at its infantile stage. Like many other Bangladeshi sweetmeats the technology of Rossomalai manufacture is also confined in the grip of a few sweetmeat traders who did not disclosed the technology to making the product to others. That is why, the product was not yet taken in to consideration by the dairy and food researchers. As a result no research information is available on the product. In this experiment Rossomalai was manufactured at Milk Vita dairy plant and compare the quality of Milk vita Rossomalai with that of product collected from the three famous sweetmeat shops. The quality of the product was matured by some physical, chemical and microbiological examination. Significant deference (P<0.01) was found in case of Rossomalai in terns of physical characteristics. It was observed from result that total solid, moisture, fat, protein, carbohydrate and ash content of Milkvita and market Rossomalai samples were 46.47 and 39.80-45.90; 53.52 and 54.09-60.19; 7.91 and 6.26-6.40; 8.29 and 5.55 - 7.03; 29.15 and 25.68-32.65 and 1.10 and 0.81-1.01 percent, respectively. Total variable bacteria differ significantly among the treatment but coliform bacteria were not significantly differing among the treatments. Physical, chemical and bacteriological examinations revealed that market Rossomalai was inferior to Milkvita Rossomalai.

  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.

  This study was conducted to know the management system, to determine cost and benefit, to identify constrains and to make recommendations for development of such small dairy farms in Jessore District. From this study, it was revealed that the milch cow per farm was 5.12 and average milk yield per day per cow was 5.78 liter. Cows were inseminated 76% by artificially and 24% by both natural and artificial means. About 68% roughage was used as dry and the rest used as green grass. Fifty four percent, 24% and 22% farms had semi pucca, kacha and pucca houses, respectively for their animals with 90% proper ventilation and 66% proper drainage system. Milking done by male 76%, female 20% and both 4%. Milk was sold to neighbors, vendors, restaurants and sweet makers. The average market price of milk per liter was Tk. 14.32. The average production cost per cow per year was Tk.. 17,790.83. Feed cost was Tk.. 14,024.54, which was 78.83% of production cost. On the basis of some problems reported by farm owners, some recommendations are made for sound dairy development in the study area.

  The present study was assigned to asses the nutritional status of individuals and household level, to measure food intake and to find out the socio-economic condition of rural household relating to nutritional status. The study was a cross sectional field survey, where samples were enrolled conveniently and random and which was conducted in a village Jugitola a less agri-based community of Gazipur District. With this view, the empirical data were collected by using pre-tested questionnaires. Socio-economic and dietary data were collected by recalling from 12 households with a total of 75 members. It was found that the average family size, land holding capacity, homestead gardening and monthly family income per household were 6 numbers, 68 decimal, 11 decimal and Tk. 6,194, respectively. The average food expenditure per household was Tk. 3387. The average non-food expenditure was Tk. 860 per family per month. Dependency ratio 1:3 was observed in about half of the families. No mal-nourished children aged under 5 years was found. It was observed that land holding, household size and income were not a factor to develop mal-nourished women. Most of the people of the survey area consumed more cereal compared to Anim. food and also consumed less amount of leafy vegetable. The per capita intake of protein, Vit.A and riboflavin is much lower than requirement. The largest part of the energy comes from cereals in rural areas. The mother consumed less amount of every type of food than other members of the family, but both the mother and children get less amount of energy than they need.

  Twenty-eight bred restored lines and four standard checks were screening for resistance to bacterial leaf blight (caused by Xanthomonas oryzae pv. oryzae), sheath rot (caused by Sarocladium oryzae), sheath blight (caused by Rhizoctonia solani), during the t. aman and boro season. The breakout and severity of percent leaf/sheath area diseased were recorded under natural infection. On the basis of disease intensity, one breeding line was found moderately resistant, 13 were moderately susceptible and 13 were susceptible and 5 were highly susceptible to BLB at t. aman season and at boro season, 5 were highly resistant, 5 were resistant, 12 were moderately resistant and 9 were moderately susceptible to BLB. In case of sheath rot, 6 were moderately resistant, 26 were moderately susceptible and 2 susceptible in t. aman season. One line was resistant, 14 moderately resistant and 17 were moderately susceptible to sheath rot in boro season. At t. aman season, 29 lines were resistant, 3 were moderately susceptible and at boro season, all cultivars including checks were resistant to sheath blight. Considering both seasons, the accession numbers 56, 57, 64, 66, 71 and 73 showed comparatively better performance against above mentioned three major rice diseases.
