The field experiment were carried out to study the “Effect of paraquat on mechanical harvesting of greengram (Vigna radiata L. Wilczek) genotypes” at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The field experiment was laid out in split- split plot design with two main plots (methods of harvesting), three sub plots (genotypes) and two sub sub plots (paraquat spray and control. All the three genotypes namely DGGV-2, DGG-1 and Nirmal recorded more than 50 cm height, bearing first pod at 30 cm above the ground and more than 11 pods were (all most all pods) found above 30 cm height, then registered higher values of yield attributes like number of branches (more than 7), length of pods (9 - 10 cm), number of pods plant-1 (12 - 17), test weight (4.4 - 5.2 g), grain yield plant-1 (3.20 - 3.53 g), pod weight (4.31 - 4.82 g), harvest index (0.29) and grain yield (1181 - 1156 kg ha-1). Therefore, these three genotypes with all these set of traits were well suited for mechanical harvesting.
