Abstract:

A field experiment was done to assess the influence of INM practices with in-situ green manuring on growth and yield of potato at College of Agriculture, Hassan, UAS, Bangalore during Kharif 2013. The experiment was laid out in a factorial Randomized Complete Block Design (FRCBD) with three replications and twelve treatment combinations including 2 fertilizer levels (75 and 100% RDF), 3 compost levels (0, 12.5 and 25 t ha-1 compost) and in-situ green manuring with sunhemp and cowpea. The investigation revealed that among treatment combinations, 100% RDF + 25 t ha-1 compost + in-situ green manuring with cowpea recorded significantly higher plant height (73.1 cm), number of leaves (83.3 plant-1), leaf area (7576 cm2 plant-1), leaf area index (6.3), leaf area duration (101.3 days) and total dry matter production (71.5 g plant-1). The higher net returns and B:C ratio (Rs. 1,01,550 ha-1 and 2.58, respectively) was recorded in the treatment with 75% RDF+12.5 t ha-1 compost + in-situ green manuring with cowpea (T4) followed by 100% RDF + 25 t ha-1 compost + in-situ green manuring with cowpea (T12). Application 75% recommended dose of NPK with 12.5 t ha-1 compost and in-situ green manuring with cowpea recorded less reduction in the tuber yield with high net returns and B:C ratio and it is economically feasible for the potato cultivation by saving 25% fertilizer and 50% compost.
