Effect on yield attributes, yield and economics of different soybean varieties for Bundelkhand region in M.P.

Abstract

The experiment entitled, “Effect on Yield attributes, Yield and Economics of different Soybean varieties for Bundelkhand region in M.P” was conducted in kharif 2018-19 at Research Farm, J.N.K.V.V., College of Agriculture, Tikamgarh (M.P.). The experiment was laid out in Randomized block design allocating fourteen varieties of soybean. For yield attributing character the variety NRC 37 gave the significantly higher number of pods and seeds than most of the remaining varieties. However, this was followed by JS 20-69. The variety JS 20-34 showed poor yield attribute characters. The variation in pod bearing ability among the varieties may be due to variability in the varietal’s inheritance. The varieties NRC 37 recorded significantly higher seed index (13.03 g) showed bigger seed size than other tested varieties. Thereafter, the varieties JS 20-69 and JS 90-41 performed equally well in this parameter (12.00 to 11.02 g). Almost the significantly lowest seed index was noticed in varieties JS 93-05 and NRC 86 (7.92 to 7.93 g). For yield and economics study the variety NRC 37 produced significantly higher seed and Stover yield and proved drought tolerant at flowering and pod formation stage than that of other tested varieties. However, the second best variety was JS 20-69. The other varieties viz. JS 335, JS 95-60, and JS 20-29, also yielded the lowest, because these were adversely affected due to drought. Accordingly, the variety NRC 37 resulted in significantly. The highest harvest index (28.60%) as compared to the remaining varieties of soybean. However, the next best varieties were JS 20-69 (27.36%) and the lowest harvest index is JS 20-29 (25.53%). Amongst the fourteen varieties under test, NRC 37 gave the maximum net monetary return of and B:C ratio This was followed by JS 20-69 and B:C ratio.
