Effect of different organic sources of nitrogen on yield and quality of kharif rice (Oryza sativa L.)

Abstract

A field experiment was conducted at the Agricultural College Farm, Bapatla, during kharif, 2012 to study the effect of different sources of organic nutrients (poultry manure, FYM, neemcake and vermicompost) and recommended dose of NPK on grain yield and quality of rice. The experimental results indicated that the different sources of organic nutrients significantly influenced the grain yield. However the quality parameters viz., protein, amylose contents, milling per cent, hulling per cent, head rice recovery, L/B ratio, volume expansion ratio, kernel elongation ratio, water uptake and solid loss were not influenced by the different organic sources of nitrogen.
