Effect of Iron Fertilization on Nitrogen and Iron Content, Uptake and Quality Parameters of Groundnut (Arachis hypogaea L.)
Year: 2018
Type: article
Abstract: A field experiment was conducted to study the effect of iron fertilization on nitrogen and iron content, uptake and quality parameters of groundnut (Arachis hypogaea L.) during kharif, 2016 at instructional farm, SKRAU, Bikaner. The results revealed that application of FeSO4 @ 25 kg ha-1 as basal + foliar spray of FeSO4 @ 0.5% at 45 and 75 DAS+ Citric acid @ 0.1% at 45 and 75 DAS + 5 t FYM ha -1 significantly increased nitrogen and iron content, uptake and quality parameters of groundnut. Nitrogen and iron content and uptake and protein content in kernels also enhanced with application of FeSO4 @ 25 kg ha-1 as basal + Foliar spray of FeSO4 @ 0.5% at 45 and 75 DAS+ Citric acid @ 0.1% at 45 and 75 DAS + 5 t FYM ha -1. However, oil content was not influenced due to soil and foliar applied iron treatment alone or in combinations. Similarly, Application of FeSO4 @ 25 kg ha-1as basal + foliar spray of FeSO4 @ 0.5% at 45 and 75 DAS + Citric acid @ 0.1% at 45 and 75 DAS + 5 t FYM ha-1 significantly increased nitrogen and iron content and uptake in kernel over control and at par with foliar spray of FeSO4 @ 0.5% at 45 and 75 DAS + Citric acid @ 0.1% at 45 and 75 DAS + 5 t FYM ha–1 as basal application treatment.
