Effect of organic source of nutrients in growth and yield parameters of Okra (Abelmoschus esculentus L.) in Karbi Anglong district of Assam

Abstract

A field experiment was conducted in the farmers’ field of Karbi Anglong district of Assam in the year 2016-17 and 2017-18 to study the effect of organic sources of inputs on growth, yield and economics of Okra (Abelmoschus esculentus L.). Results revealed that FYM @ 5t/ha + Vermicompost @ 1t/ha + Seed treatment with azotobacter and PSB @ 7.5 g each/100g+ soil application of rock phosphate @ 13 Kg/ha (T3) showed significantly higher values of plant height (108.50 cm), first fruiting node (5th node), number of fruits per plant (9.25), average fruit weight (21.05 g), average fruit length (16 cm), average fruit girth (4.75 cm) and yield (80.58 q/ha) than T4 (control). The economical parameters in terms of Net return (Rs.105640.00), Gross return (Rs. 161310) and B:C ratio (3.04) were also found to be considerably higher in T3 as compared to T1 (Recommended NPK) and T2 (Recommended NPK + FYM). Farmers’ practice (T4) recorded the least B:C ratio of 2.17. Therefore, T3 was found to be the feasible option for obtaining higher yield and profitable income.
