EFFECT OF POULTRY MANURE AND FARMYARD MANURE WITH AND WITHOUT CHEMICAL FERTILIZERS ON THE GROWTH AND YIELD OF BRRI DHAN28

A field experiment was conducted at the Agrotechnology Field Laboratory of Khulna University, during boro season 2005 to find out effects poultry manure (PM) and farmyard (FYM) in presence absence chemical fertilizers on BRRI dhan28. The laid-out a randomized complete block design with three replications. There were ten treatments viz. T1: 100% RFD (Recommended fertilizer doses), T2: RFD+10 t FYM, T3: RFD+ 5 T4: 50% RFD+5 T5: 10 T6: + PM, T7: 2.5 T8: T9: PM T10: Control (without manures fertilizers). doses inorganic N, P, K, S Zn 80, 50, 40, kg ha-1. All combined application significantly increased plant height, number tiller hill-1, dry matter grain straw yield over control. highest recorded treated plot which similar FYM plot, while lowest Half recommended ha-1 or produced statistically yields as by indicates that can be replaced without any loss yield.
