Abstract:

A field experiment was conducted during Kharif 2015 and 2016 for two consecutive years at Regional Research Station Farm, TNAU, Paiyur to study on effect of zinc and iron application on yield, available nutrient status and nutrient uptake of finger millet under rainfed condition. The experiment was laid out in a randomized block design with 10 treatments and replicated thrice. The pooled mean results revealed that an application of zinc and iron either enriched with FYM or foliar form along with macro nutrients (NPK) at different rates significantly influence the grain yield and nutrient (N, P & K) uptake of finger millet. Higher grain (2258 kg ha-1) and straw yield (3692 kg ha-1) were obtained in the treatments of application of RDF (40:20:20 N: P2O5: K2O kg ha-1) along with ZnSO4 (0.5%) + FeSO4 (1%) + citric acid (0.1%) spray twice at vegetative and flowering stages which was statistically on par with NPK + ZnSO4 (12.5 kg ha-1) + FeSO4 (25 kg ha-1) as EFYM. The lower grain yield (1613 kg ha-1) was recorded with application of RDF alone. The total nutrient uptake such as N, P & K at harvest stage were higher with the treatment receiving NPK + ZnSO4 (0.5%) + FeSO4 (1%) + citric acid (0.1%) spray twice at vegetative and flowering stages which was on par with NPK + ZnSO4 (12.5 kg ha-1) + FeSO4 (25 kg ha-1) as EFYM. The higher iron uptake was recorded in the treatment receiving NPK along with ZnSO4 (0.5%) + FeSO4 (1%) + citric acid (0.1%) spray twice at vegetative and flowering stages which was statistically on par with T6, T10 and T5 treatments. The higher nutrient uptake of zinc was recorded in the treatment receiving NPK + ZnSO4 (12.5 kg ha-1) + FeSO4 (25 kg ha-1) as EFYM which was statistically on par with T9, T5, T10, T7 and T3 treatments.
