INFLUENCE OF THE INTEGRATED NUTRIENT MANAGEMENT ON THE GROWTH, YIELD AND NUTRIENT CONTENTS OF BINA DHAN 8

Abstract

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.
