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.
