An attempt was tried to evaluate the different greengram genotypes for enhancement of Fe nutrition in calcareous soil of Somankottai Perivu village of Tiruppur district in Tamil Nadu. A field experiment was conducted with two treatments viz., control (-Fe) and 50 kg FeSO4 kg ha-1 (+Fe) in factorial randomized block design (FRBD) and replicated thrice with recommended dose of NPK @ 25:50:25 kg ha-1. Among the ten genotypes tested, the CO 6 was found to record higher seed yield and Fe content. It was followed by, the CO 5 performed with comparable yield and Fe content. The performance of remaining genotypes is given in the descending order COGG 973 > CO 7 > COGG 979 > COGG 668 > Samrat > Pusha vishal. The COGG 975 genotype showed poor performance and recorded lower Fe content, uptake and protein content in seeds.

Abstract


An attempt was tried to evaluate the different greengram genotypes for enhancement of Fe nutrition in calcareous soil of Somankottai Perivu village of Tiruppur district in Tamil Nadu. A field experiment was conducted with two treatments viz., control (-Fe) and 50 kg FeSO4 kg ha-1 (+Fe) in factorial randomized block design (FRBD) and replicated thrice with recommended dose of NPK @ 25:50:25 kg ha-1. Among the ten genotypes tested, the CO 6 was found to record higher seed yield and Fe content. It was followed by, the CO 5 performed with comparable yield and Fe content. The performance of remaining genotypes is given in the descending order COGG 973 > CO 7 > COGG 979 > COGG 668 > Samrat > Pusha vishal. The COGG 975 genotype showed poor performance and recorded lower Fe content, uptake and protein content in seeds.
