Response of different levels of zinc and FYM on soil health and yield attributes of cluster bean (Cyamopsis tetragonoloba L.) Cv. Durgapura Jay

Abstract

The present investigation carried out at research farm, department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during the kharif season of 2019 with the objective to response of different levels of Zinc and FYM on soil health, growth and yield attributes of guar [Cyamopsis tetragonoloba L.] Cv. Durgapura Jay. The experiment was laid out in a randomized block design with nine treatment combinations, consisting of three Zinc levels (0, 50 and 100%) and FYM (0, 50 and 100%). In soil parameters bulk density (Mg m-3) of soil was recorded 1.03 (Mg m-3) in treatment T9 (100% Zinc + 100% FYM). Similar results were also reported in the particle density (Mg m-3) of soil was recorded 2.48 (Mg m-3) in treatment T9 (100% Zinc + 100% FYM). Soil pore space was recorded 51.43% in treatment T9 (100% Zinc + 100% FYM). It was observed that Soil pH after harvesting 7.20 which was recorded in T9 (i.e. 100% Zinc + 100% FYM). Electrical conductivity (dS m-1) after harvesting was 0.18 recorded with T9 (i.e. 100% Zinc + 100% FYM). Organic carbon (%) of soil after harvesting was 0.71% in T9 (i.e. 100% Zinc + 100% FYM). Available nitrogen in soil was 317.25 kg ha-1 after harvesting in T9 (i.e. 100% Zinc + 100% FYM). Available phosphorus in soil was 32.99 kg ha-1 after harvesting and highest was in T9 (i.e. 100% Zinc + 100% FYM). Available potassium in soil was 210.38 kg ha-1 after harvesting and highest was in T9 (i.e. 100% Zinc + 100% FYM). It was observed that for post-harvest, treatment T9 (i.e. 100% ZnSO4 + 100% FYM) was best in terms of growth, yield and economic parameters with maximum plantheight 235.02 cm, number of leaves per plant 42.97, number of clusters per plant 32.15, pods per cluster 13.61, pods per plant 99.29, seeds per pod 8.96 and pod yield 64.19 and maximum cost benefit ratio of 1:4.48.
