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 @ at 45 and 75 DAS+ Citric acid @ at 45 and 75 DAS + 5 t FYM ha -1 significantly increased nitrogen and iron content, uptake and quality parameters of groundnut. | Effect of iron fertilization on nitrogen and iron content, uptake and quality parameters of groundnut (Arachis hypogaea L.)
