Abstract

The present experiment was carried out during 2020-21 and 2021-22 in Jorhat, Assam with the objective to optimize the planting density for maximum yield and yield related attributes. The experiment was laid out in factorial randomized block Design with 3 factors viz. spacing, fruit thinning and INM (Integrated nutrient management) with three replications and the data of individual years were subjected to pooled analysis. The spacing levels were D1 (2.5m x 2m), D2 (1.5m x 1m) and D3 (1mx 1m) where F1 (no thinning), F2 (Thinning up-to 1 fruits /primary vine) and F3 (Thinning up-to2 fruits/primary vine) were the fruit thinning levels. A total of 4 INM treatments were given i.e. N1 (100% RDF), N2 (50% RDF + 50% RDN through FYM), N3 (50% RDF + 50% RDN through vermicompost) and N4 (50% RDF + 25% RDN through vermicompost + 25% RDN through FYM). The treatments significantly influenced the various parameters except a few. The experiment's findings showed that thinning the fruit and increasing the spacing between them had a favorable effect on the watermelon's growth and yield-related characteristics. Additionally, integrated nutrient management and fruit thinning at level F2 enhanced the watermelon's growth, yield, and quality metrics. Among the levels, N3 (50% RDF + 50% RDN through vemicompost was found to be the best.
