Abstract

The present experiment was carried out on okra ‘COBhH 1’ during 2010-11 with the objective of studying the influence of nutrients, organics and bio-agents on growth, yield, leaf nutrient status and economics of okra. The results pooled over two seasons indicated that application of Pseudomonas fluorescens (seed treatment @ 10g kg-1 + soil application @ 2.5 kg ha-1 with FYM and foliar spray of humic acid @ 0.2 per cent improved the growth, yield and leaf nutrient contents. The parameters such as plant height, fruit length, fruit girth, fruit weight, fruits per plant, fruit yield per plant and per ha marketable fruit yield per plant and per ha were found highest with application of P. fluorescens. The shortestinter nodal length, the lowest first flowering node, earliness in flowering and higher leaf nutrient content of N, P, K, Ca, Mg, S and micronutrients were observed with application of 0.2 % humic acid as foliar spray. The highest net return per hectare and benefit cost ratio were observed with application ofP. fluorescens.
