TABREATUS A field experiment was conducted at the research field of Sher-e-Bangla Agricultural University. Dhaka, during the period from November 2012 to May.2013 to study the effect of organic manures viz.. Poultry manure. Mustard oil cake, sesame oil cake, vermicompost and inorganic fertilizers on yield and nutrient uptake by BINA dhan-8. There were altogether II treatments viz.T0 (Control), 1' (100% NPKSZn). 12 (50% NPKSZn + Poultry manure@5t hi'), T3 (75% NPKSZn + Poultry manure@5t ha'). 14 (50% NPKSZn + Mustard oil cake@5t ha"). T5 (75% NPKSZn ± Mustard oil cake@5t ha"). T, (50% NPKSZn +Sesame oil cakc2I;5t ha'). T7 (75% NPKSZn + Sesame oil cake@5t hi'), T8 (50% NPKSZn +Vermicompost@St hi'), T9 (75% NPKSZn + Vermicompost,5tha 1) and Ito (Poultry manure1.25t ha' + Mustard oil cake4i).1.25t ha" - Sesame oilcake @1.25t ha" + Vermicompost @1.25t ha"). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. All the yield contributing characters were significantly influenced by the application of both organic manures and inorganic fertilizer combination. highest plant height, leaves, panicle length,1000-seed weight grain yield , straw yield and biological yield were obtained when 75% of the recommended doses of N,P,K,S,Zn fertilizer along with 5 t hi sesame oil cake was applied and the lowest values of all the parameters were obtained from the plants fertilized with neither organic manures and inorganic fertilizers. Nutrient contents of BINA dhan S were also significantly affected by different treatments. Highest N.P.K and S contents of both grain and straw were obtained from the same treatment The lowest nutrient contents were obtained from the control treatmentThe overall results suggest that farmers should be advised to use 75% of NPKSZn fertilizers along with 5 ha" sesame oil cake for getting higher yield and quality in terms of nutrient contents of BINA dhan 8under the agro-climatic condition of SALJ.

NAJMUS SADAT The experiment was conducted in the Agronomy field laboratory of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from December, 2012 to May, 2013 to study the effect of cowdung and chemical fertilizers on growth and yield of aromatic rice BRRI dhan50. Five different levels of fertilizers and cowdung as recommended by BRRI for BRRI dhsn5O were used as: Ti: 100% Inorganic fertilizer, T2: 75 % Inorganic fertilizer + 25% Cowdung, Ti: 50 % Inorganic fertilizer + 50% Cowdung, 14: 25 % Inorganic fertilizer + 75% Cowdung, T5: 100% Cowdung. Significant variations were found in growth and yield parameters and nubient content of rice due to the various combinations of organic and inorganic fertilizers. It seems from the results that 100% inorganic fertilizers (Ti) showed the best result during initial stage of plant height but in later stages combination of organic and inorganic fertilizers (1'2) showed best results (82.97cm and 91.87cm respectively). Leaf length, number of total tillers hilt1 and number of effective tillers hill-' showed best result during different growth stages of rice plant by using chemical fertilizer only (Ti) and all of that cases it was followed by 12. Panicle length (22.52 cm), filled grain panicle-' (135.33), grain yield (4.07 t ha1), 1000 seed weight (20.84 g) and dry weight of straw (0-45 kg rn-2) always counted superior result for the treatment T2: 75 % inorganic fertilizers + 25% Cowdung. Percent unfilled grain (17.1$) was highest in T5 and harvest index (45.45) was superior for the treatment Ti. And all of the cases inferior results were given by T5 treatment i.e 100% Cowdung only. Significant effect also found in different chemical composition of straw and grain by using different combinations of fertilizer doses. Significantly the highest N, P and K contents of grain and straw were recorded in T1 (100% Inorganic fertilizers) and 12 (75 % Inorganic fertilizers + 25% Cowdung). The lowest N, P and K content in grain and straw were found from the treatment using Cowdung (15) only.
