Studies on the effect of integrated nutrient management and bio enhancer on growth and economics of Rabi onion (Allium cepa L.)

Abstract

The present investigation entitled “Studies on Effect of integrated nutrient management and bio enhancer on productivity of Onion (Allium cepa L.)” was carried out during the year 2015-16 in Rabi season at present investigation was carried out at the Agricultural Farm Razaula, M.G.C.V.V. Chitrakoot (M.P.) The experiment was laid out in randomized block design with 14 treatments and three replications. Significantly higher values were recorded for plant height (52 cm), number of leaves (8.85), leaf length (39.27 cm), leaf width (1.96 cm), collar thickness (6.38 cm), fresh weight of leaves ( 86.44 g) and dry weight of leaves (11.44 g) in the treatment T1 consisting of 100 per cent of recommended RDF (100:80:80 kg/ha) which was at par with T13 (51.68 cm), While lowest growth was recorded in T14 (45.83 cm). The highest net return and benefit: cost ratio was found in T1 of Rs 135669.05/ha and 4.5 respectively and lowest net returns were found in T14 of Rs 75979.80/ha and lowest benefit: cost ratio (2.37) was found under T3.
