N.; Robbani, M.; Ali, M.; Bose, S. K.; Islam, M. M. The experiment was conducted to develop an appropriate storage method and shelf life of two guava varieties, namely Swarupkathi and Kazi Piara under different postharvest treatments. Six postharvest treatments viz., control, hot water, neem extract, brown wrapping paper, perforated white polythene bag and non-perforated white polythene bag were assigned to the guava fruits. The two factors experiment was laid out in a completely randomized design with three replications. Among the physico-chemical parameters such as reducing and non-reducing sugar contents increased significantly, whereas titratable acidity and vitamin C contents decreased during storage in all treated and untreated fruits. Between two varieties, the shelf life of Kazi Piara (9.89 days) was higher than that of Swarupkathi (7.94 days). The postharvest treatments showed highly significant variation in the shelf life of guava. The shelf life extended up to 13.00 days by using non-perforated white polythene bag. The fruits stored in nonperforated white polythene bag having longer shelf life resulted slow change in its chemical components. The shelf life of variety Kazi Piara could be extended up to 13.00 days by using non-perforated white polythene bag. 2014-01-01T00:00:00Z http://localhost:8080/handle/123456789/2121 COLLECTION TECHNOLOGY OF WOOL FOR MARKETING Yasmin, F.; Talukdar, M. A. I.; Chowdhury, M. S. Z. H. This research was conducted to find out the performance of sheep-wool in Bangladesh. A complex multi- equation system model is established to represent the collection of wool from sheep using both Annual Selling and Simulation Matrix (SIMM) Model Technologies. The objective of this research was to determine wool production, effective wool collection and marketing from sheep farming. The number of sheep like I, 10, 100, 1000 etc. is reared up by the small, medium large and commercial farmers. Results show sheep producer can sale all kids at the end of the year except selling female sheep and can collect I, 10, 100, lOOOkg wool from rearing 1, 10, 100, 1000 female sheep respectively. The shearing of wool twice and selling kids in a year can be a technology of wool collection. So if sheep-producers' target is only wool collection then needs establishing wool local market first. Therefore, at present raw and finished wool market needs to be established before starting wool production i.e. sheep farming. 2014-01-01T00:00:00Z http://localhost:8080/handle/123456789/2120 INTEGRA TED MANAGEMENT FOR HIGHER CURD YIELD AND QUALITY OF BROCCOLI (Brassica oleracea var. italica L.) Khatun, K.; Hossain, F.; Saha, S. R.; Mostarin, T. An integrated management was taken to investigate the effect of macronutrients, micronutrients, cowdung, mustard oilcake and mulches on different yield contributing characters, yield and quality parameters of broccoli during October 2011-March 2012 at the Horticulture Farm, Sher-e-Bangia Agricultural University, Dhaka. The experiment included six treatments using T,= 15 tlha Cowdung + NlIsP"K'20 (recommended dose of cauliflower) ,T2= IS tlha Cowdung + N'20P,ooK,.oS20kg/ha ,T3= IS tlha Cowdung + N'20P,ooK'40S20+ Zn.Bl.sMo, kglha, T.= 20 tlha Cowdung + 400 kglha mustard oilcake , Ts= N120P'OOK140S20+Zn .BuMol kg/ha + 20 tlha Cowdung + 400 kg/ha mustard oilcake and water hyacinth mulch ,T6= NI2OP,OOK,.oS20+Zn.BuMol kglha + 20 tlha Cowdung + 400 kg/ha mustard oilcake. Significant variation was recorded in case of plant height, number of leaves, leaf length, leaf breadth, days to curd initiation, stem length, stem diameter, primary curd diameter, curd weight, number and weight of secondary curd, curd yield, moisture (%) , ascorbic acid, ~ carotene content, protein and carbohydrate percentages except total fat percentages, iron and calcium content. The maximum curd yield (24.15 t/ha) was found from T6 treatment and the minimum was recorded from T4 (15.26 tlha) treatment. T6 treatment showed the best performance on the maximum yield and quality curd production over all the other treatments. 2014-01-01T00:00:00Z http://localhost:8080/handle/123456789/2119 EFFECT OF INTEGRATED MANAGEMENT APPROACH FOR COMBATING ANGOUMOIS GRAIN MOTH (Sitotroga cerealella) POPULATION AT DIFFERENT GENERATION Akter, T.; Jahan, M.; Ali, M. Effect of integrated management approach was studied for combating angoumois grain moth. Sitotroga cerealella (Olivier) at different generation in terms of adult emergence, adult longevity and population ratio during the period from March 2011 to September. 2011 in the Department of Entomology. Sher-eBangia Agricultural University. Dhaka. Bangladesh. The treatments of the studies were: Cleanliness of the storage including the container and premises (sanitation) + Use of dried neem kamel powder @ 10 gmJkg (T,); Cleanliness of the storage including the container and premises (sanitation) + Use of dried tobacco leaves powder @ 5.0 gmJkg (T2); Sanitation + use of insecticide in the empty bins as preventative measure + Use of dried neem kamel powder @ 10 gmJkg (T); Sanitation + use of insecticide in the empty bins as preventative measure + Use of dried tobacco leaves powder @ 5.0 gmlkg (T,); Sanitation + Release of Trichogramma evanescense after 30 days interval (number of Trichogramma = lOO/plastic container or replication (Ts): Sanitation + Application of fumigant practice with phosphine gas with doses depending on the temperature and humidity and the pest population (To) and Untreated control (T,). The study was laid out in a Completely Randomized Design (CRD) with four replications. In I" generation no adults emerged in To treatment which was followed by T, (9.67) whereas the highest (38.00) adult was recorded in T, (untreated control) treatment. Similar trend of adult emergence was observed in 2"" generation and 3'd generation of the pest. In I" generation no adult longevity was recorded in To treatment whereas the highest (10.00 days) adult longevity was recorded in T, treatment. Statistically significant variation was recorded for number of female. male and their ratio for I st. 2"" and 3'd generation of angoumois grain moth in stored rice grain due to integrated management approaches. 2014-01-01T00:00:00Z
