Performance of soybean (Glycine max (L.) Merrill) varieties to different spacings on growth, yield characters and yield under mechanization

Abstract

The field experiment was conducted at College of Agriculture, Pune, Maharashtra during kharif 2018 to study the performance of soybean (Glycine max (L.) Merrill) varieties to different spacings under mechanized conditions. Five spacings S1- 45 x 5 cm2, S2- 45 x 10 cm2, S3- 60 x 5 cm2 and S4- 60 x 10 cm2. (Under mechanized condition) and S5- 45 x 5 cm2 (under conventional condition) and three varieties V1: KDS-344 (Phule Agrani), V2- KDS-726 (Phule Sangam), V3- KDS-753 (Phule Kimaya) were tested in split plot design with three replication. The growth characters viz., plant height (cm), plant height (cm), number of branches plant-1, number of functional leaves plant-1, leaf area plant-1 (dm2), number of root nodules plant-1, fresh and dry weight of root nodules plant-1 (g), days to 50 % flowering and days to maturity and dry matter plant-1 and yield attributes viz., number of pods plant-1, number of seeds pod-1, weight of pods plant-1 (g), seed yield plant-1 (g), straw yield plant-1 (g) and test weight (g) were significantly influenced at spacing 60 x 10 cm2 under mechanized condition. Among the varieties KDS-344 gave significantly superior in all growth and yield attributing characters except test weight (g). The test weight (g) was significantly highest value by variety KDS-726 (Phule Sangam).
