ABSTRACT

An experiment was conducted to evaluate the residual effect of poultry manure on grain and straw yield and mineral concentration of BR11 rice during the Aman season. To study the residual effect of poultry manure and chemical fertilizers on yield and yield contributing characters of rice. The experiment was laid-out in a Randomize Complete Block Design (RCBD) with three replications assigning 12 treatment combinations comprising 4 levels of poultry manure (@ 0,2.5,5,7.5 t ha^-1) and 3 levels of chemical fertilizers (control, half and full recommended dose). Poultry manure was applied during previous crop season. Only chemical fertilizers were applied during this experiment. The recommended full dose of urea, TSP, MOP and gypsum were 150, 100, 60 and 50 kg ha^-1, respectively. The residual effect of poultry manure and chemical fertilizers increased plant height, effective tillers hill^-1, panicle length, and 1000-grain weight, no. of grains panicle^-1, grains and straw yields of BR11 rice. The highest grain yield (5.700 t ha^-1) and straw yield (8.930 t ha^-1) were obtained by the T₁₂ (PM_7.5 N₂ P₂ K₂ S₂) treatment. Combined effect of residual poultry manure and chemical fertilizers had significantly positive effect on the availability of nitrogen, phosphorus, potassium, sulphur, copper, zinc, manganese, iron, boron, and protein content in grain and straw of BR11 rice. Nutrient content in grain and straw was lowest at T₁ (control) treatment and the highest was at T₁₂ treatment. T₁₂ treatment was the best of all the treatments. It may be concluded from the above study that residual effect of poultry manure and chemical fertilizer showed better performance on yield of BR11 rice and had significant effect on N, K micronutrient (Fe, Zn, Mn and B) and protein contents in rice grain and straw.
