Influence of organic and inorganic N fertilization on growth yield and economics of transplanted rice
Abstract
A field study was carried out during kharif and rabi seasons of 2001–02 and 2002–03. An appreciable improvement in growth components (plant height, and number of tillers) and grain yield were evidenced in kharif and rabi rice with organic manure Sesbania aculeate, FYM, poultry manure and pressmud along with inorganic N (urea) applied 50% each. The integration of 50% N as organic through sesbania aculeate with 50% as inorganic (urea) brought about conspicuous yield improvement with 24 and 25 per cent in kharif and rabi rice respectively over 100% inorganic N alone. This treatment also recorded the highest net return and benefit.
