  An experiment on the control of spiraling white fly (Aleurodicus dispersus Russel) by spraying detergent (wheel powder, Liver Brothers Ltd.) was conducted. Wheel powder, a cheap and readily available detergent in Bangladesh was sprayed to control the white fly. Wheel powder was sprayed in different concentration among which 10 g litre-1 of water and 15 g litre-1 of water were found more effective in controlling white fly. The concentration 20, 30 and 40 g litre-1 of water were found serious leaf burning, even total leaf dropping after 3rd spray.

  This study deals with the analysis of cure rate estimation under uncensored data. Cure models have been proposed for cure rate estimation. We have tried to estimate the parameter of the model using Maximum Likelihood Method (MLE). The analysis showed that the cure rate estimator converges to the true parameter when considered both cured and non-cured group. The analysis also showed that the estimating equation converges to the true equation of parameter when considered only non-cured group.

  An assessment was conducted in Sirajganj district of Bangladesh to determine the pond fishery resources and sustainable development of fisheries. Researchers observed 123 (56%), 59 (27%) and 37 (17%) of ponds were culture, semi-culture and non-culture ponds and on the basis of the season 192 (88%) of perennial and 27 (12%) of seasonal ponds were found out of 219 during this study period. It was observed that the highest number of ponds 175 (80%) was personal pond which occupied by the single owners and 44 (20%) was leased in pond which privately occupied by the multiple ownership. The range of cost for lease was varied from Tk. 6,000-8,000 acre-1. The average pond fish production from 219 sampling ponds in Sirajganj district was 80.51 kg decimal-1. Therefore, by using sustainable development model, pond fisheries production can be increased to a considerable level and contributes to the national economy.

  Experiments were conducted in the field to response five radiation induced jute (Corchorus olitorius L.) mutants against jute stem weevil, Apion corchori Marshall. Evaluations were made on the basis of percentages of plants infested by weevil and number of knots found on each mutant. It was found that the significantly difference between five jute mutants with respect to infestation by jute stem weevil. The mutant OM-48 and OM-51 recorded higher percentages of infested plants and increased number of knots than the check variety O-9897. Mutant OM-1, OM-42, OM-47 and check variety O-9897 were rated as moderately resistant (with 1.88 to 3.31 knots/plant) to jute stem weevil. It was also found that the lower parts of the plants (1-30 cm) had more number of knots than the upper parts.

  The study was conducted at Bangladesh Agricultural University Dairy Farm, Mymensingh to find out the skin thickness in different regions of body of dairy cows and the relationship of skin thickness to milk yield. Twenty five crossbred milking cows of indigenous and Sahiwal were selected for experiment. The skin thickness was measured by Vernier calipers. The skin thickness of the same animals is varies at different regions of the body. The average skin thickness of neck, dewlap, chest, abdomen and hindquarter were 3.33, 4.12, 2.93, 4.23 and 4.20 mm, respectively and the average skin thickness was 4.20±0.90 mm at the five different regions and the milk yield were negative and was significant (p<0.05). The results of the present study indicated that 29% of the variation in milk yield of cows depend on skin thickness and 71% depends on another factors. Form the study it was found that milk production of low skin thickness group was higher then that of medium and high skin thickness group. This may be a fact that low skin thickness cows did not deposited extra fat in their body and utilized most of her energy for milk production.

  Fabrics were prepared by plain weaving with the blended yarns made of sulphonated jute fibre in different combination with cotton, rayon, acrylic, polyester and silk waste. It has been observed that the blending of the sulphonated jute fibre with cotton or any other flexible fibre improved the draping properties of the fabrics made there from and that these fabrics in actual use have gracious look and firmness almost to the same extent of those draping properties of the cotton fabrics. The dye ability of this blended fabrics was studied using a basic dye (Rhodamine-B red) and reactive dye (Procion-M red). The dye absorption of jute increases from 68 to 88% as it was sulphonated and the sulphonated jute blended fabrics took up almost the same of amount of dyes which was around 70% from both dye-bath, indicating that the accessibility of blended fabric samples to the dye molecules was practically the same. The colour shades on different fabric sample were almost similar in compare with dyed cotton fabrics. The colour fastness of the blended fabrics were also closed to the cotton fabrics.

  A study was conducted in a typical village to evaluate the effect of pre and postpartum supplementation (UMMB) of indigenous cows on the performance of their calves. Thirty-two cows were supplemented with UMMB from 6 months of prepartum to 6 months of postpartum period and 30 cows were fed only traditional feed (without UMMB). The cows were milked once a day in the morning. The calves were tied up at the night and allowed to free access or suckling to the dams during the whole day. The birth weight of the calves in supplemented (UMMB) group (14.61 kg) was significantly (p<0.05) higher than the control group (12.00 kg). Similarly, live weight gain of supplemented calves was also significantly (p<0.01) effected by the cows supplemented with UMMB (117 g/d) than the cows without UMMB (56 g/d). The mortality was 9% in control group whereas no calf did not died during the experimental period. So, it can be concluded that supplementation to pre and postpartum cows with UMMB can have better effect on the performance of their calves.

  An investigation was conducted to study the aortic valves of the heart of the indigenous cattle in cardiac research for bio-prosthetic purpose in Bangladesh. The measurement & observation of bovine heart & aortic valve in different age groups ( 1.5 years to 4.5 years old) are the findings of this research work. The results revealed that the size ranged from 21 to 35 mm and orifice diameter are similar in comparison with implanted aortic & mitral valves at National Institute of Cardiovascular Disease & Suhrawardee Hospital, Dhaka. It indicated that the selected bovine heart valve (specially aortic valves) were similar to human valve size & can be used in future for implantation as per as the size is concerned. On the other hand, the heart valves are devoid of blood supply as a result there is no problem with tissue rejection as it is in cornea transplant in the eye. The prospect is bright for further study regarding making these tissue valves implantation worthy for clinical use in the Cardiovascular Disease Hospital & private clinics in our country.

  The effect of mulch and bulb size on the growth of onion was studied using four mulch treatments, viz., non-mulch i.e. control, ridge method of mulch, straw and black polyethylene mulch; and five different sizes of seed bulbs, viz., very small (0.5 g), small (1.0 g), medium (1.5 g), large (2.5 g) and very large (4.5 g). Mulching and bulb size had significant effect on plant height, leaf number, pseudostem diameter, root number and length. The interaction effect of mulch and bulb size was significant in plant height, root length and root number but it was non-significant in leaf number and pseudostem diameter.
