Abstract:

An experiment was conducted to study the efficiencies of selected protocols for integrated management of nutrients in Brinjal ( Solanum melongena L.)at Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya at Gayeshpur, Nadia during 2011 with Brinjal (cv. F 1 - hybrid VNR -60) as test crop. The experiment has been laid out in a 4 x 4 factorial design with three replications and was conducted with recommended doses of NPK supplemented with selected bio-fertilizers (PSB and Azotobacter along with micronutrients (Fe, Zn, B) fertilizers. Integrated management of nutrients through supplementation of NPK by bacterial fertilizers along with micronutrients inputs increased basal girth, plant height, no. of shoots/plant, no. of fruits/plant and average fruit weight significantly over values obtained under administration of the recommended dose of NPK alone. Maximum increments in basal girth, plant height, no. of shoots/plant, no. of fruits/plant and average fruit weight thus obtained remained to the tune of 36.09, 20.84, 43.95, 123.52 and 60.00% respectively over control. Maximum increments in Brinjal yields thus obtained remained to the tune of 60 % over control. The economic benefits of different management systems were observed to be to the tune of 19.25-60.00 % more net return over the control counterparts (recommended dose of NPK only). This calls for judicious management of natural resources and evolving cost-efficient technologies which can push up vegetable production at a lesser cost rather than expanding the area.
