Effect of integrated nutrient management on grain, straw yield and soil fertility status after harvest of chickpea

Abstract

The field experiment was conducted in the Pulses Improvement Project MPKV, Rahuri, Dist. Ahmednagar during 2007-08 to -2011-12 on medium black soil to study the “Effect of Integrated nutrient management on grain, straw yield and soil fertility status after harvest of chickpea.” The experiment was laid out in randomized block design included ten treatments. The treatment were, T1 - Absolute control, T2 – GRD, T3 - As per soil test, T4 - STCRC (25 qha-1 target), T5 - Vermicompost @ 2.5 tha-1, T6 - FYM @ 5 tha-1, T7 - Jeevamrut – 3 times application, T8 - Jeevamrut – 6 times application, T9 - 25% N-FYM + 75% RDN, T10 - 25% N-Vermicompost+ 75% RDN. The pooled results (2007-08 to 2011-12), resulted that there was significant influence of different treatments on grain yield of chickpea. Application of T10, 25% N- Vermicompost + 75% RDN through urea treatments, gave significantly higher grain yield (2733 kgha-1), which was followed by T4, (2450 kgha-1). In case of straw yield gave maximum T10, (3274 kgha-1) with application of 25% N- Vermicompost + 75% RDN through urea treatments, which was followed by T9, (2916 kgha-1). The data presented revealed, that the maximum organic carbon content (0.058%), available nitrogen (240.7 kg ha-1), Phosphorous (14.75 kg ha-1) and potassium (531 kg ha-1) was obtained by application of T10, 25% N- Vermicompost + 75% RDN through urea treatments. The application of 25% N- Vermicompost + 75% RDN through urea increased the uptake of nitrogen (139.4 kg ha-1), Phosphorous (42.4 kg ha-1) and potassium (74.7 kg ha-1), which was followed by T4, treatment with uptake of nitrogen (131.1 kg ha-1), Phosphorous (38.6 kg ha-1).
