Effect of Land Configuration, Seed Rates and Variety on Growth and Yield of Soybean in Central India

Abstract

The present experiment was conducted under ongoing ‘All India Coordinated Research Project’ (AICRP) for Dry land Agriculture at College of Agriculture, Indore to study the effect of land configuration, seed rates and variety on growth and yield of soybean in Central India. The study was carried out with 03 main plot treatments (03 land configurations i.e. L1- Flat sowing-45 cm, L2- Raised bed of 90 cm with 3 Rows bed-1 and L3- Raised bed of 60 cm with 2 Rows bed-1) and 04 sub plot treatments (02 varieties of soybean i.e. V1-RVS 2001- 4 and V2-JS335; 02 seed rates i.e. S1-60kg ha-1 (75% of Normal seed rate) and S2 40kg ha-1(50 %of Normal seed rate)). The various observations related to plant growth parameters viz., plant height, number of branches per plant, leaf area, number of nodules per plant, plant dry weight, number of pods per plant, number of seeds per pod, grain weight per plant, grain yield, straw yield and harvest index were recorded. The obtained data was analyzed by method of variance and the null hypothesis was tested by the ‘F’ test. Further, the critical difference was worked out to judge the difference between the two treatment means. The results revealed that the land configuration, seed rates and variety showed significant effect on growth and yield of soybean.
