Response of Vermicompost and Neem Cake on Soil Health and Yield Attributes of Cluster Bean (Cyamopsis tetragonoloba L.) var. Pusa Naubahar

Abstract

An experiment was carried out at during the Zaid season of 2021-22 at central research farm of Soil science and agriculture chemistry at different level of vermicompost and neem cake on soil health, growth and yield attributes of cluster bean [Cyamopsis tetragonoloba L.] var. Pusa Naubahar. The experiment was laid out in a randomized block design with nine treatment combinations of total 27 combination consisting of three vermicompost levels (0, 50 and 100%) and neem cake (0, 50 and 100%). In soil bulk density (Mg m-3) of soil was recorded 1.18 Mg m-3, particle density (Mg m-3) of soil was recorded 2.14 Mg m-3, pH of soil after harvesting 7.56, Electrical conductivity (dS m-1) after harvesting was 0.270, Organic carbon (%) of soil after harvesting was 54.5 , available nitrogen in soil was 276.49 kg ha-1 after harvesting, available phosphorus in soil was 30.74 kg ha-1 after harvesting , available potassium in soil was 262.65 kg ha-1 after harvesting   and highest was in T9 (100% NPK + 100% VC + 100% NC). It was observed that for post-harvest treatment T9 (100% NPK + 100% VC + 100% NC) was best in terms of growth, yield and economic parameters with maximum plant height 82.25 cm, number of leaves plant-1 26.19, number of branch plant-1 6.90, pods plant-1 79.50, pod yield 56.13 and maximum cost benefit ratio (C: B) of (1:2.52).
