Abstract

The investigation was carriedout tofind out the “Effect of integrated nutrient management on seed production okra (Abelmoschus esculentus (L). Moench)”, using yellow vein mosaic virus resistant variety Varsha Uphar, under sub-tropical conditions of Jammu, Vegetable Experimental Farm, F.O.A, SKUAST, Jammu, Main Campus - Chatha, during rainy season 2005–2006. The experiment was laid out in randomized block design (Factorial) with three levels of nitrogen and phosphorus viz, 50, 75 and 100 per cent (RDF) i.e. 60:30 kg N & PP5 respectively. Potassium was applied uniformly to all the treatments @ 30 kg per hectare in addition to the three different biofertilizers i.e. Azotobacter, Azospirillum and Phosphorus Solubilizing Bacteria (PSB) as soil application @ 2kg ha′ were applied as a soil treatment. There were 12 treatment combinations which were replicated thrice in 36 plots of size, 2.80 x 1.40 sq m with a spacing of 45 x 30 em. There was no significant effect on pod length and seed vigour index. Application of biofertilizers decreased days taken to seed maturity and increased pod width, 100 seed weight, number of seeds perpod and seed yield. Seed yield was maximum in F2B3 which was at par with F3B3 and followed by F3B2. Application of F2B3 (75% recommended dose of fertilizer (NP) along with phosphorus solubilizing bacteria) as soil application @2 kg/ha proved to be most profitable and remunerative for seedproduction of okra crop. The treatment combination of F2 x B3 recorded highest seed yield thereby gave gross income to the tune of Rs. 87040.00 and net income of Rs. 64188.00/ha and Cost: Benefitratio of 1:2.80.
