A Field experiment was conducted at Cashew Research Station of All India Coordinated Research Project on Cashew (ICAR) under OUAT, Bhubaneswar, Odisha, India to study the performance of pre released cashew genotypes for vegetative growth parameters, yield attributing traits and nut yield. The experiment was laid out by adopting RBD replicated thrice having four plants per treatments. The treatment consisted of 11 entries such as BH 6 (Jagannatha), BH 85(Balabhardra), H 1597(Amrutha), H 662, H 675, H 32/4, K 22-1, H 11, H 14, and Goa 11/6(Bhaskara) including BPP 8(H 2/16) as local check. The clonal planting materials were planted at a spacing of 7.5m x 7.5 m during 2003 by adopting recommended package of practices uniformly to raise a good crop. The results on vegetative growth parameters revealed that the cashew types K-22-1 exhibited semi tall growth habits hence can be utilized for adopting high density planting in cashew with proper canopy management. The overall results revealed significant superiority of cashew genotypes such as BH-6, BH-85, H-1597, H-32/4, Goa-11/6 and BPP-8 for majority of the vegetative growth parameter such as plant height(m), trunk girth(cm), canopy spread(both in E-W and N-S direction) and canopy spread (m2). Similarly, the cashew types such as BH 85, BH 6, and H 1597 recorded significantly better performances for mean nut weight(7.13 to 7.80 g), shelling %(28.70 to 31.10%) and mean annual nut yield(13.40 to 14.82kg ha-1) than rest of the tested cashew types. It may be concluded that the cashew genotypes such as BH 85 (Balabhardra), BH 6 (Jagannatha) and H 1597 (Amrutha) may be recommended for commercial cultivation in the state of Odisha.
