Description Journal article
Two field experiments were conducted at
the Research Farm of ICAR-Indian Institute of Water
Management, Mendhasal, Odisha with wet season
rice. The objective of the first experiment was to
compare the effect of inorganic fertilizers (IF) with the
integrated nutrient management (INM) using in situ
green manure Sesbania and complimentary dose of IF
on rice yield, energy use, economics and residual soil
fertility. In the second experiment, the IF was compared
with the organic nutrient management (ONM)
using in situ green manure Sesbania and vermicompost.
The results of the first experiment revealed that
grain and straw yields of rice were similar with the
INM and IF. However, the INM helped in reducing
energy input (24%), improving energy efficiency
(35%) and net return (20%). Soil organic C, available
N and P contents increased significantly by 14%, 8%
and 53%, respectively, for the INM at the end of
3 years. The results of the second experiment revealed
that the ONM registered rice grain yield reduction by
8% but increased net return (8%) due to a higher
premium of INR 1750 (US $ 26.21) t-1 paddy grain.
The ONM treatment reduced energy input (39%) and
enhanced energy efficiency (57%) as compared to the IF. Soil organic C, available N and P contents
increased by 23%, 39% and 12%, respectively, for
the ONM at the end of 3 years. Thus, the practice of
ONM or INM using Sesbania green manure-cumcover
crop saved energy and fertilizer, and maintained
soil fertility.
