    EFFECTS OF INORGANIC PHOSPHORUS AND POTASSIUM ALONG WITH COWDUN.G AND VERMICOMPOST ON GROWTH, YIELD AND NUTRIENT CONTENT OF BRRI dhan62
    (Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University., 2014-06) HOSSAIN, MD. AWLAD
    An experiment was conducted at the experimental field of the farm of Sher-e-Bangla Agricultural University during the period from May to October, 2014 to study the effects of different combinations of cowdung (CD) and vermicompost (VC) along with P and K on BRRI dhan62 using RCBD with three replications. The treatments were - Control. 'F1 - 100% inorganic fertilizer (IF), T2 —25 % P from + 75% p from IF. T3 —50 % P from CD + 50% P from IF, 1'4 75 % P from CD + 25% P from IF. T5 — 25 %Pfrom VC +75%Pfrom IF, T6-50%P from VC± 50%Pfrom IF, T7 — 75 %P from VC + 25% P from IF. T8— 25% K from CD + 75% K from IF, T950% K from CD + 50% K from IF. T10— 75% K from CD + 25% K from IF. T11 —25 % K from VC + 75% K from IF, T12 —50% K from VC + 50% K from IF. T13 —75% K from VC 25% K from IF. Most of the growth and yield parameters differed significantly due to the combinations of organic and inorganic sources of P and K. Ilighest plant height. effective tillers bilE', total tillers hill1, longest panicle were produced by 50% K from VC + 50% K from IF while 50% p each from VC and produced the highest number of filled grains panicleT The highest grain yield was obtained from 50% K from VC + 50% K from IF which was statistically similar to 50% p from VC + 50% P from IF. The highest straw yield was observed from 50% P from VC + 50% P from IF which was statistically similar to 50% K from VC + 50% K from IF. The highest P and S content in grain was observed from 50% p from VC + 50% p from IF while highest K content in grain was observed from 50% K from VC ± 50% K from IF. The overall results suggest that farmers can be advised to use 50% P or K from VC and 50% from IF for better growth and nutrient content of BRRI dhan62 under the agro climatic condition of Sher-e-Bangla Agricultural University.
