Abstract
To find out the effect of organic inputs on productivity, soil fertility and sustainability in ricewheat rotation, a long term field experiments were started from the year 1986 at G.B.P.U.A &T, Pantnagar (India) on silty loam soil and after 10 years of continuous research in the same experiment, the study of another eleven years (1998-2009) on rice–wheat crop cycles were undertaken. Application of Sesbania green manure along with FYM significantly enhanced the average grain yield of rice (5.96 t/ha), wheat (4.71 t/ha) and average total system productivity in terms of rice equivalent yield (11.68 t/ha). Soil fertility status was also significantly enhanced over control and recommended dose of fertilizers. The sustainability index for rice – wheat system was highest (0.90) with 100 % use of organic nutrient sources i.e. Sesbania along with FYM treatment on long term basis over control and recommended NPK. Currently there is growing concern about the sustainability of rice-wheat cropping system as the growth rate of rice and wheat yield either stagnating or declining. The combination of poor soil fertility and inadequate, unbalanced, and inefficient use of fertilizers contributes much to this problem. Therefore, here we demonstrate that the continuous use of either 100 % of organic nutrient sources i.e. Sesbania green manure + FYM or organics along with recommended doses of NPK sustained the system productivity of rice – wheat and also maintain the soil health through maintaining soil physical and biological properties in Indo – Gangetic plains of India.
