Abstract:
A field experiment was carried out during Rabi, 2019-2020 at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat). There were 12 treatments laid out in randomized block design with a view to study the effect of Iron ferti – fortification in grain Amaranthus (Amaranthus hypochondriacus L) grown under Typic Ustocrepts. The results revealed that recommended dose of fertilizer, 15 kg FeSO₄ ha^-1 through enriched 200 kg FYM recorded 15% higher grain yield over control. While, maximum grain Fe content and uptake was recorded under soil application of 11.25 kg FeSO₄ ha^-1 through enriched 200 kg FYM. Among the different Fe ferti-fortification treatment recommended dose of fertilizer along with soil application of FeSO₄ @ 7.5 kg ha^-1 through enriched 200 kg FYM showed highest iron use efficiency (15.07%) as well as partial factor productivity (862) over rest of the treatments. However, highest Fe harvest index (13.7%) was noticed in treatment receiving recommended dose of fertilizer coupled with FeSO₄ @ 11.25 kg ha^-1 and bio NPK Consortium is adjudged as the best Fe ferti-fortification strategy for grain amaranthus crop in the middle Gujarat condition.
