Abstract: The present investigation was carried out at the All India Coordinated Research Project on Cashew, Zonal Research Station, Darisai, Birsa Agricultural University, Ranchi, Jharkhand India during 2017-2018. Twelve cashew genotypes namely NRCC sel-1, NRCC sel-2, M44/3, M15/4, BPP3/33, BPP10/19, BPP30/1, BPP3/28, H303, H255, H367 AND H68 were included for the study. The collected grafted plants were planted at a spacing of 7.5 m x 7.5 m following Randomized Block Design (RBD) having six plants per treatment and replicated twice. Recommended package of practices were adopted uniformly to raise a good crop. Data recorded on various vegetative growth parameters, yield attributing traits and nut yield of different cashew varieties revealed that Among the twelve tested varieties, BPP30/1 recorded maximum for the vegetative parameters like tree height (4.52m) and trunk girth (60.25cm), while canopy spread in North-South direction maximum found in variety M15/4(3.75 m) and canopy spread in East-West direction was recorded maximum in variety, BPP3/33 (3.95 m). Cashew varieties such as H255 (2.44 m) and H367 (2.76m) recorded minimum plant height among the evaluated cashew varieties, indicating their suitability for high density planting. Cashew variety, H367 recorded the minimum trunk girth (41.10 cm) as well as canopy spread in both in East-West (2.15 m) and North-South direction (1.85 m). The number of flowering laterals /m² ranged from minimum 8.90 in NRCC sel-1 to maximum 45.60 in H303. Maximum flowering duration was recorded in variety, NRCC sel-2 (10986 days) followed by H303 (106.74 days), H225 (104.85) and M15/4 (101.25). Minimum flowering duration was recorded in variety, BPP3/28 (87.40) means indicating early variety. Average apple weight ranged from minimum 46.20 g in BPP30/1 to maximum 98.70 g in H367. The nut weight varied from minimum 5.10g in H68 to maximum 8.2g in H303.
