Abdus Mushrooms arc non-green fungal plants occurring seasonally all over the world in various habitats varying from plains to thick forests or green meadows to roadside pathways. It comprises a large heterogeneous group having various shapes, sizes, appearance and edibility. They are recognized as the alternate source of good quality protein and arc capable of producing the highest quantity of protein per unit area within a short time from the worthless agro-wastes (Chadha and Sharma, 1995). To find out the effect of the supplementation of wheat bran, rice bran, mustard oil cake, cow dung and poultry litter to paddy straw on yield and various yields contributing characters of oyster mushroom. The experiment was conducted in the Plant Tissue Culture (PTC) laboratory and the Mushroom Culture House (MCH) of mushroom culture center at Saver, Dhaka, May to August 2005 with a view to study the influence of supplements to the paddy straw substrate on the growth and yield of oyster mushroom (Pleurotus ostreatus). Experimental design was CRD. Supplements were mixed with substrate separately at 50 %, 40%, 30%, 20% andl0%.The highest number of fruiting body (65.25) was observed in cow dung then ricc bran (62.75) and then wheat bran (61.75) supplemented with 40% level. The different level of nutrient materials was influence the biological yield, economic yield and mycelium run rate. The economic yield of oyster mushroom was increased gradually up to 40% level of nutrient materials and then decreased. Nutrient material cow dung was more pronounced than wheat bran. The highest (8.66) benefit cost ratio was obtained from cowdung with 40% level of supplements while the lowest 5.31 BCR was observed in mustard oil cake at 50% level. Mycelium run rate per day in spawn packets of different supplement differ significantly. The time (18.50days) required to complete mycelium running was lowest in cow dung supplemented at 40% level. From stimulation to primordial initiation, from primordial initiation to first harvest, from stimulation to first harvest and total harvest days were influenced by the different supplements at the different levels. The best level of nutrient material is 40% because the highest benefit was obtained by using 40% level of supplement in paddy straw substrate. The best nutrient material is cowdung, then wheat bran, rice bran, poultry litter and lastly mustard oil cake.

Hatiya Island of Noakhali district was the location of the study area. The study covered 80 homesteads from four unions, 20 from each union. The information was collected by using structured questionnaires, formal and informal interviews and field observations. Some information was also gathered by group discussion with the farmers. The information was analyzed by using descriptive statistics. Fruit diversity was described by Species richness, Relative prevalence and Species diversity. In the study, 28 fruit species were identified. Among 28 fruit species, Banana, Mango and Jujube were found in the 100% homestead surveyed. The Relative Prevalence of most common species like Banana(21.71), Betel nut(17.59), Coconut(10.39), Mango(7.69), Date(6.98), Papaya(5.77), Guava(5.67), Jujube(3.61) were very high while that of less common species like Kaow(0.08), Pineapple(0.11), Litchi(0.17), etc. were found very low. Banana and Betel nut were found highly diverse (0.986) fruit species followed by Mango (0.984), Jackfruit (0.984) and Coconut (0.984). The findings revealed that age of the farmers has no relationship with the fruit diversity, while education, family size, area of homestead, area under fruit have low and positive relationship with the fruit diversity but not significant. Annual income from fruit and knowledge about fruit has low and negative relationship with the fruit diversity but not significant. Extensions Media contact have a highly significant and negative relationship with the fruit diversity. Total number of species was found highly positively correlated with fruit diversity. The traditional homestead fruit production system and fruit diversity in the study area was found very poor due to management practices.

Moklesur The present experiments were carried out in the laboratory of the Department of Horticulture and Postharvest technology in Sher-eBangla Agricultural University, Dhaka with an objective to asses the postharvest losses and shelf life of tomato during the period from 15 March to 25 April 2006. The experiment comprised of two factors i.e. several colors of polythene bag (viz: Control, Black Polythene, Blue polythene, Yellow polythene and White transparent polythene) and different types of polythene (viz: sealed and perforated) in refrigerated condition (10 11 0 c) and room temperature (28 0 c).The colours of polythene were found to have significant influence on total weight loss, time required for colour development, firmness, moisture percentage, dry matter percentage and shelf life of tomato. Black polythene was found to be superior to other colours of polythene in respect of all the parameters both in room and refrigerated condition. Types of polythene had significant effect on all the parameters except time required for colour development (days). Sealed polythene was found to be the best in all the parameters except in case of shelf life of tomato both in refrigerated condition and room temperature. There was significant variation among the treatments resulted from the combination of colour and types of polythene in respect to all the parameters except firmness percentage. Shelf life of tomatowas the highest (19.52 days)at room temperature and (34.09 days) at refrigerated condition. Again the highest firmness (%),moisture (%),dry matter (%) was in black sealed polythene (96.75%), (98.38%) and (9.73%)at refrigerated condition and (25.80%), (85.36%) and (7.00%) at room temperature respectively. The best result was obtained from black polythene when combined with sealed condition.

ARFAN An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University. Dhaka during the period from October 2004 to February 2005 to study the , . effect of different levels of fertilizer and manure viz. control. organic manure (23.11- t/ha), inorganic fertilizer (Urea 3~2 k&/lta, MP 180 kglba, TSP 158 kgIha) and mixture of organic and inorganic fertilizer (Cowdung 11.5 tJha, Urea 177 kg/ha, TSP 62 kg/ha and MP 63 kglha) and different mulching materials viz. no mulch ~), rice straw (MI). water hyacinth (M2) and black polythene (M3) on the growth and yield of lettuce. The experiment was conducted in the"'Rand()mizedComplete Block Design ~ ... (RCBD) with three replications. "APpliCation of different levels 'of fertilizer and manure significantly influence the growth and yield of lettuce. Organic plus inorganic fertilizer treatment resulted in the highest gross (46.01 tJha) and marketable yield (45.46 t/ha). The highest yield (45.7t1ha) was recorded from black polythene mulch, while the lowest (38.71t/ha) was recorded from unmulch treatment. The combined effect of various levels of fertilizer and manure as well as mulches were ..... also found significant incase of lettuce production. The use of organic plus inorganic fertilizer with black polythene mulch produced the highest gross (50.27 t/ha) and marketable yield (49.62 tlha). The lowest gross (35.44 tJha) and marketable yield (34.9 t/ha ) were recorded from the control treatment where no manure and fertilizer as well as no mulch were used. The benefit cost ratio (BCR) was the maximum (3.23) in the treatment combination of cowdung with water hyacinth mulch whereas, the minimum (2.09) was recorded from the water hyacinth with no fertilizer treatment A Thesis Submitted to Department of Entomology, Faculty of Agriculture.
