ABSTRACT
An experiment was conducted to study the effect of fertilizers and pesticides on the growth and yield of BRRI Dhan 30 rice. There were twelve treatments T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11 and T12. The rates of different fertilizers were 90 kg N from urea, 50 kg P2 O5 from TSP, 40 kg K2 O from MP, 10 kg S from gypsum, 4 kg Zn/ha from ZnSO4 .H2 O. The recommended doses of diazinon (Di) and sodium arsenite pesticides as 1680 and 500 ml/ha, respectively were used in the experiment. All the treatments significantly increased the grain and straw yields of BRRI Dhan 30 rice over control except T12 which showed a decreasing trend. The combined application of N, P, K, S, Zn and Di produced the highest grain yield (4773 kg/ha) which was 47.31% increase over control. On the other hand, single application of As decreased the yield (3088 kg/ha) by 4.69% over control.
