Performance of different vegetable cowpea (Vigna unguiculata (L.) Walp) genotypes under Rayalaseema region of Andhra Pradesh

Abstract

The present exploration was carried out to study the performance of different vegetable cowpea genotypes under Rayalaseema region of Andhra Pradesh during the period from November, 2019 to February, 2020 at Horticultural Research Station, Dr. Y. S. R Horticultural University, Mahanandi, Kurnool district, Andhra Pradesh involving twelve genotypes were replicated thrice under Randomized Block Design. Among the twelve genotypes studied, Kashi Nidhi took minimum days for first flowering (39.00 days), 50% flowering (41.67 days), first picking (51.00 days), whereas Kashi Shyamal and Kashi Gauri took maximum days for final harvest (98.00 days). Kashi Nidhi recorded maximum pod length (42.93 cm), maximum pod diameter (8.60 mm), maximum green pod weight (21.07 g), highest green pod yield plant-1 (373.20 g), highest green pod yield plot-1 (9.67 kg), highest green pod yield ha-1 (161.17 q ha-1) and highest TSS content (4.94oBrix). In the present study, Kashi Nidhi is the most promising genotype with respect to yield characters and the mean values were found to be superior than the national check Kashi Kanchan for most of the characters.
