Abstract:
A study with 9 different therapies, including the experiments used a randomized block design (RBD) with three replications and consisted of nine treatments: control (T₁) 100% RDF (T₂), 100% RDF + Zn (0.5%) (T₃), 100% RDF + B (0.5%) (T₄), 100% RDF + Rhizobium (20 g kg^-1) (T₅), 100% RDF + Zn (0.5%) + B (0.5%) (T₆), 100% RDF + Rhizobium (20 g kg^-1) + Zn (0.5%) (T₇), 100% RDF + Rhizobium (20 g kg^-1) + B (0.5%) (T₈), and 100% RDF + Rhizobium (20 g kg^-1) + B (0.5%) + Zn (0.5%) (T₉). Based on the findings of the current study, it is possible to draw the conclusion that the application of 100% RDF + Rhizobium (20 g kg^-1) + B (0.5%) + Zn (0.5%) applied to chickpea significantly increases plant height, number of branches per plant, accumulation of dry matter, and yield attributes such as number of grains per pod, number of pods per plant, and test weight (g). Additionally, the results demonstrated that, among the various fertility levels, the application of 100% RDF + Rhizobium (20 g kg^-1) + B (0.5%) + Zn (0.5%) considerably improved productivity metrics, including grain yield, stover yield, and biological output, over the control, except for harvest index. Higher economic values were observed for chickpea when 100% RDF + Rhizobium (20 g kg^-1) + B (0.5%) + Zn (0.5%) were applied, with the exception of the B:C ratio (2.74) which is maximum when 100% RDF + Rhizobium (20 g kg-1) were applied. Gross return was Rs. 110810.10 ha-1, net return was Rs. 69121.10 ha^-1, and cultivation cost was Rs. 41689.
