Effect of organic fertilizers on growth and yield of coriander (Coriandram sativum) under subabul (Leucaena leucocephala) alley cropping system

The experiment was conducted to estimate the effect of different organic fertilizer levels on growth and yield of coriander, Coriandram sativum L under subabul, Leucaena leucocephala (Lam) de Wit alley cropping system. Coriander crop was grown under four to five years old existing tree species of subabul-based alley cropping system. The experiment was laid out in randomized block design (RBD) with three replications and 8 treatments. The treatments used were T₀: control, T₁: 100% recommended dose of fertilizer (RDF) through vermicompost (VC), T₂: 100% RDF through neem cake (NC), T₃: 100% RDF through farmyard manure (FYM), T₄: 50% RDF through VC + 50% RDF through NC, T₅: 50% RDF through NC + 50% RDF through FYM, T₆: 50% RDF through VC + 50% RDF through FYM and T₇: 50% RDF VC + 25% RDF NC + 25% RDF FYM. Results revealed that the T₇ emerged superior in respect of growth attributes as well as yield of coriander and gave maximum seed yield (19.76 q/ha) followed by treatment T₄ with 16.06 q/ha seed yield while minimum was recorded in control. Therefore a systematic coriander cropping with sufficient management practices is more beneficial for livelihood on a sustainable basis.
