Abstract

Five hundred thirty three cashew genotypes of seedling origin with 25 years age were evaluated under rainfed conditions in poor, red gravelly lateritic soils. It was found that, 3 trees namely Tree No 33, 38 and 50 recorded more nut weight and yield. Tree No. 38 recorded more nut weight (8 g) and yield (24.3 kg/tree) followed by Tree No 50 with nut weight (7 g) and yield (23.5 kg/tree) and Tree No 33 with nut weight (7 g) and yield (20.7 kg/tree). Thirteen trees viz; Tree No. 34, 35, 51, 62, 63, 73, 110, 127, 385, 407, 408, 412 and 448 recorded nut weight in the range of (7-11 g) and less yield (8.25 - 17.3 kg/tree) and remaining 517 trees recorded less nut weight in the range of (2-3.9 g) and less yield (5- 18.9 kg/tree) than control BPP-2.
