Evaluation of groundnut for kharif uplands and summer rice fallows

Abstract

A widely divergent collection of 93 groundnut varieties was screened to select the bestsuited variety for the kharif uplands and summer rice fallows. They were evaluated in preliminary trials in uplands as well as in rice fallows. The varieties exhibited wide diversity for important economic traits within and between seasons and many of them were far superior to the recommended varieties. Based on the performance in the preliminary trials, thirty one varieties including the recommended varieties (TMV 2 and TMV 7) were selected for comparative yield trials. They were tested in two seasons each in uplands and rice fallows. The varieties differed in yield and other economic traits in both seasons. The performance of the same variety, m general, varied from upland to rice fallows. TG 14 in uplands and TG 3 in rice fallows were the top ranking varieties. Spanish Improved was found to be a high yielder at both seasons. Five promising varieties were selected and they along with 3 standards were further tested in multi-locational trials at 5 locations in summer rice fallows and 6 locations in kharif uplands. The multi-locationa! trials further confirmed that TG 14 and TG 3 were the highest yielders in uplands and rice fallows respectively. Spanish Improved was also another high yielder at both seasons.
