Abstract
A field experiment was conducted at Regional Agricultural Research Station, Tirupati, Acharya N.G. Ranga Agricultural University during rabi, 2022 and 2023 to study the impact of mid-season moisture stress (40-80 DAS) on yield attributes and quality traits of groundnut genotypes. The experiment was carried out in randomized block design with factorial concept with two main treatments i.e., control and mid-season moisture stress (40-80 DAS) and 12 sub treatments i.e., two check varieties and ten contrasting groundnut genotypes in three replications. Among the groundnut genotypes and check varieties tested for their tolerance to moisture stress the genotypes, TCGS 2326, TCGS 1792, K9 and TCGS 2333 were found to withstand mid-season moisture stress and maintained highest 100 kernel weight, shelling percentage, protein and oil content indicating tolerance to moisture stress.
