Abstract:
Experiment was conducted in a farmer’s holding at Peryumpathi village of Zamin Kaliyapuram Block of Coimbatore district (10°77¢32.9² N, 76°93¢13.7²E. The experiment was conducted with forty groundnut genotypes replicated three times in Randomized Block Design (RBD). The crop was grown up to maturity and harvested. The soil was deficient in available zinc (Zn) status with DTPA - Zn content of 0.92 mg kg-1.The genotypes exhibited high variation with respect to yield, Zn content and Zn uptake. The highest pod yield was registered in JL 24 (2592 kg ha-1) which was comparable with CO 7 (2559 kg ha-1), ABHAYA (2556 kg ha-1) and TMV 7 (2546 kg ha-1). The genotypes Abhaya (1866 kg ha-1) and ALR 3 (1848 kg ha-1) recorded the highest kernel yield and the genotypes VRI 13153 (799 kg ha-1) and VRI 13154 (814 kg ha-1) recorded lowest kernel compared to other genotypes. The genotype Dharani (54.7 mg kg-1) exhibited higher kernel zinc content while the lowest was recorded in VRI 13154 (18.1 mg kg-1). Kernel zinc uptake ranged from 14.7 g ha-1 to 100.5 g ha-1 with mean value of 44.9 g ha-1. The genotypes viz., VRI 8, TMV 2, TMV 7, JL 24, Narayani and Dharani were found to be efficient genotypes showing higher uptake of zinc even at low zinc soil condition. Based on the yield data and Zn content, genotypes, CO7, ALR 3, TMV 7, TMV 13, JL 24 and ABHAYA were identified as efficient genotypes with respect to kernel yield. DHARANI, NARAYANI, TCGS1157, TMV 7, VRI 8, TMV 1, TMV 2, TAG 24 and TMV 13 were grouped as efficient genotypes with regard to kernel zinc content.
