H.; Haque, M. Z.; Kundu, S. The main objectives of this study were to determine the level of food insecurity condition faced by the rural people of South Sadar Upazila of Comilla District and to explore the relationship between food insecurity of the respondents and their selected characteristics. The study was conducted with randomly selected 120 rural households of three villages namely, Dumuria, Lohipur and Dayapur of Chowara union under the South Sadar upazila of Comilla District. Family head of each of the farm families was treated as the respondent. Pearson's product moment correlation co-efficient (r) was computed to examine the relationship between the variables. Food insecurity faced by the rural people was the dependent variable and ten selected characteristics of the respondents constituted. the independent variables of this study, More than two- thirds (66.67%) of the respondents were found to be in food secured condition followed by low insecured (20%) and medium food insecured (13.33%). None faced high food insecured condition. Correlation (r) between food insecurity and characteristics of the respondents showed that education, farm size, annual family income and daily time allocation in farm work of the respondents had negative significant relationship, while family size and daily dietary needs of the family had positive significant relationship with food insecurity. 2012-01-01T00:00:00Z http://localhost:8080/handle/123456789/2229 CHANGES OF PHYSICAL AND CHEMICAL PROPERTIES OF POST HARVEST SOIL OF T. AMAN RICE AS INFLUENCED BY ORGANIC AND INORGANIC PHOSPHORUS Islam, M. S.; Solaiman, A. R. M.; Karim, A. J. M. S.; Rahman, G. K. M. M.; Haque, M. M. Due to low organic mailer content the agricultural soils of Bangladesh has poor physical and chemical condition. Moreover, the continuous use of phosphorus (P) fertilizers build-up of excessive P in many cultivated soils has created an interest in the combined use of organic and inorganic P fertilizer. Hence, a field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University Farm, Gazipur, Bangladesh during the Aman season of July 2008 to January 2009 to investigate the effects of combined application of inorganic phosphorus (Pi) and organic phosphorus (1),,)on the changes of physical and chemical properties of soil after T. Aman cultivation. The eight treatments were To, Control/ no fertilizers; T" recommended dose offertilizers; Tz, 50% P through TSP and 50% P through cowdung; T), 75% P through TSP and 25% P through cowdung; T" 50% P through TSP and 50% P through poultry manure; Ts, 75% P through TSP and 25% P through poultry manure; To, 50% P through TSP and 50% P through household wastes; T1, 75% P through TSP and 25% P through household wastes. The experiment was laid out in randomized complete block design (RCBD) and replicated thrice. The physical and chemical properties of the soils were influenced directly by the above mentioned treatments. The physical properties of soil such as particle density and bulk density at different soil depth and plough pan decreased in response to addition of organic matters whereas no significant changes were found in response to inorganic P. The rate of improvement of chemical properties such as organic carbon (OC), cation exchange capacity (CEC), total nitrogen, available Phosphorus (P), exchangeable potassium (K), available sulphur(S), exchangeable calcium (Ca), exchangeable magnesium (Mg) and exchangeable sodium (Na) was higher with inorganic plus organic amendment than to inorganic alone. In addition, soil pH decreased in all treatments. Based on the above results it is suggested that the combined use of inorganic and organic P significantly improve physical and chemical properties of post harvest T. Aman soil. 2012-01-01T00:00:00Z http://localhost:8080/handle/123456789/2228 PERFORMANCE OF Pleurotus geesteranus MUSHROOM GROWN ON DIFFERENT SUBSTRATES Shelly, N. J.; Ahmed, K. U.; Rahman, M. H.; Kabir, K. Different substrates such as sawdust, paddy straw, paper waste, pulse straw and sugarcane bagasse were used to evaluate their effects on the growth and yield of four different strains of Pleurotus geesteranus mushroom. The minimum days required from stimulation to primordia initiation (DRSPI) (3.75) and first harvest (DRSFH) (6.75) were recorded when PG-2 was cultivated on sugarcane bagasse and the maximum DRSPI (14.00) and (DRSFH) (18.00) were recorded when PG-3 was cultivated on pulse straw. The highest numbers of effective fruiting bodies (43.50) were found in PG-4 when cultivated on paper waste. The highest biological yield (248.30g) and efficiency (99.30 %) was recorded when PG-4 was cultivated on paper waste and the lowest biological yield (107.00g) and efficiency (42.80 %) was found when PG-3 was cultivated on pulse straw. 2011-01-01T00:00:00Z http://localhost:8080/handle/123456789/2227 COMPARATIVE STUDY OF HEMATOLOGICAL AND BIOCHEMICAL PROFILES OF REPEAT BREEDING ZEBU COWS Pariza, K. F.; Hossain, M. M.; Awal, M. A.; Islam, J.; Islam, M. A. The study was undertaken to know the hematological and biochemical profiles of repeat breeding zebu cows. Blood samples from cows with repeat breeding syndrome were collected for hematological, biochemical and humoral immune response analysis. The erythrocyte sedimentation rate (ESR) was higher and hemoglobin (Hb) percentage was lower in repeat breeding cows than the normal cyclic cows. The packed cell volume (Pf.V) was lower in repeat breeding cows than in normal cyclic cows. Total erythrocyte count (TEC) is not signiticantly different whereas total leukocyte counts (TLC) significantly higher in repeat breeding cows. The bilirubin concentration was no! significantly higher (P< 0.01) in repeat breeding cows compared to the control groups of cows. The mean serum IgG was lower in repeat breeding cow than control groups of cows. 2011-01-01T00:00:00Z
