Effect of Varieties and Crop Geometries on Yield and Profitability of Soybean in Semi – Arid Climate of Telangana

Abstract

A field study entitled ʻʻEvaluation of varieties at varied crop geometry for yield maximization in soybeanʼʼ was conducted at College farm, Agricultural College, Polasa, Jagtial, PJTSAU, during the kharif season of 2018. The experiment was laid out in split-plot design with three replications to evaluate the performance of promising varieties of soybean (V1- Basar, V2- JS 335, V3- KDS 756 and V4- MACS 1281) and to standardize the crop geometry for Soybean varieties (S1- 45 x 10 cm, S2- 30 x 10 cm, S3- 45 x 05 cm and S4- 35 x 05 cm) under rainfedsemi arid conditions of Telangana. The results obtained from the present experiment indicated that among the varieties the yield attributes and yield are numbers of pods plant-1, number of seeds pod-1, seed yield, stalk yield and harvest index (%) and monetary returns of KDS 756 variety was significantly higher as compared to other varieties followed by Basar, MACS 1281, respectively. Hundred seed weight was significant among varieties and was higher with variety KDS 756 followed by MACS 1281, JS 335 and Basar. JS 335 showed inferior performance regarding yield attributes yield and monetary returns. Among crop geometry 30 x 10 cm recorded higher yield characters and monetary returns followed by 45 x 05 cm, 30 x 05 cm and 45 x 10 cm, respectively.
