Abstract

Ten blackgram genotypes were evaluated with and without iron for their tolerance to iron deficiency in terms of chlorophyll content, plant growth and seed yield under field conditions in black calcareous soil. Among the genotypes, COBG 6 was found efficient which registered higher plant growth and yield and chlorophyll and followed by ADT 3, TMV 1, CTU 17-4 and COBG 703. The T.K Local showed poor performance by registering low chlorophyll content and low yield. Soil application of Ferrous sulphate @ 50 kg ha^-1 (+Fe) resulted in higher plant growth and yield in all the genotypes as compared to control (-Fe).

Keywords

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.

Keywords
