Effect of methods of sowing and spacing on growth and yield of soybean (Glycine max L.)

Abstract

A field experiment entitled “Effect of methods of sowing and spacing on growth and yield of soybean (Glycine max L.)” was conducted at Agronomy Farm, College of Agriculture, Nagpur, during kharif season of 2021-22 in Factorial Randomized Block Design (FRBD) with eight treatments and three replications. Treatment combinations were comprised of two sowing methods viz., ridges and furrow and broad bed furrow and four treatments of spacing viz., 45 cm x 5 cm, 45 cm x 10 cm, 45 cm x 15 cm and 45 cm x 20 cm. Results revealed that, growth and yield attributes viz., plant height, number of branches plant-1, number of root nodules plant-1, number of days to 50 % flowering, dry matter production plant-1, number of pods plant-1, weight of grains plant-1 and straw yield plant-1, seed and straw yield (q ha-1) were significantly higher due to methods of sowing on broad bed furrow. As regards spacing, growth and yield attributes viz., plant height, number of branches plant-1, number of root nodules plant-1, dry matter production plant-1, number of pods plant-1, weight of grains plant-1 and straw yield plant-1 were significantly higher at spacing 45 cm x 20 cm. However seed and straw yield (q ha-1), gross monetary returns, net monetary returns (Rs. ha-1), protein and oil yield (kg ha-1) were significantly maximum at spacing 45 cm x 5 cm whereas, interaction between methods of sowing and spacing were found non-significant.
