Abstract

Proper soil fertility management is one of the prime importance in an endeavor to increase crop productivity. Hence, an experiment was conducted at the Soil Science Field Laboratory, BAU, Mymensingh during Aman season of 2017 to investigate the growth and yield performance and rice quality under different fertilizer management. The experiment was laid out in a split plot design with two varieties i.e. (V1) BRRI dhan56 and (V2) BRRI dhan71 in the main plots and four fertilizer treatments such as T1 (Control), T2 (soil test based fertilization), T3 (farmers practice) and T4 (soil test based fertilization and 5 t/ha cowdung) in the subplots with three replications. Results found that, T4 treatment produced the highest grain and straw yield in both varieties. The highest N, P, K, S content (%) and uptake (kgha-1) in both grain and straw were also recorded in T4 treatment. BRRI dhan71 performed better than BRRI dhan56 in terms of yield, nutrient content and uptake. From the combinations of variety x treatment, V2T4 (BRRI dhan71 x Soil test based fertilization and 5 t/ha cowdung) was the best for maintaining rice yield and quality. Therefore, this combination could be recommended with some farmer’s field trials for sustainable rice production without declining soil fertility.
