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 (5 th 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.

Effect of organic and inorganic source of nutrient on growth, yield and quality attributes of okra seed cv. Kashi Pragati

“…Organic and inorganic combined nutrient supplies have favourable effect on increasing the growth yield quality characters. These findings are in close conformity with Dutta, (2020). In conclusion, the combined application of organic and bio-fertilizer (Vermicompost @ t/ha + PSB @ 5 kg/ha + Azospirillum @ 5 kg/ha) improved plant height, number of branches, number of fruit per plant, fruit weight, fruit length, fruit yield per plant, seed weight per plant, seed yield per plot, seed yield, 100 seed weight and germination percentage Moreover, vigor index Ⅰ increase with the application of vermicompost @ 5 t/ha and vigor index Ⅱ increase with the application of Mustard cake @ 2.0 t/ha.…”
