Impacts of Calotropis and Azadirachta Green Leaf Manure and Bio Decomposer on Growth and Yield of Lentil

Abstract

A field experiment was conducted to study the effect of integrated nitrogen management on growth and yield of lentil (Lens culinaris Madik.) at Agronomic Research Farm, R. S. M. (P. G.) College, Dhampur (Bijnor) during the Rabi season 2023. The experiment was laid down in a randomized block design having seven treatments i.e. Control, RDN (80% N) + Calotropis gigantea green leaf manuring (GLM) (20% N), RDN (80% N) + Neem GLM (20% N), RDN (80% N) + Calotropis gigantea GLM (20% N) + waste decomposer soil application (WDSA), RDN (80% N) + Neem GLM (20% N) + WDSA, RDN (80% N) + Calotropis gigantea leaf Cutting (20% N) dipped in waste decomposer (WD) solution, RDN (80% N) + Neem leaf Cutting (20% N) dipped in WD solution) and replicated three times. Significant increase in growth characters (plant height and fresh weight), yield contributing character (number of pods) and yields (grain yield and straw yield) was observed with integrated nitrogen management over control. Moreover, among integrated nitrogen management treatments, the integration of RDN (80% N) + Neem leaf Cutting (20% N) dipped in WD solution) came out to be best for growth parameters, yield attribute and yield. It is concluded from the experiment that RDN (80% N) + Neem leaf Cutting (20% N) dipped in WD solution is the most effective treatment for enhancing lentil production under Dhampur conditions. Recommendation of this findings would allow Lentil farmers to save money which otherwise would be spent on nitrogenous fertilizer.
