dc.description.abstractThe present study was taken up to evaluate the “Effect of zinc and iron nutrition on growth and yield of Finger millet (Eleusine coracana .L)”. An experiment was conducted during kharif , 2018 at College Farm, College of Agriculture, PJTSAU. The study was taken up in sandy loam. The soil of the experimental site was low in organic carbon (0.42 %), available nitrogen (132 kg ha-1 ), P2O5 (18.13 kg ha-1 ) and high in K2O (464.8 kg ha-1 ).The DTPA extractable zinc and iron was lower than the critical limit. The soil was slightly non-saline in nature. This experiment was conducted in Randomized Block Design with 14 treatments and 3 replications. The treatments were viz.,T1: RDF (60-40-30 Kg N- P2O5-K2O ha-1 ), T2: RDF + Vermicompost @ 5.0 t ha-1 , T3: RDF + ZnSO4 @ 50 kg ha-1 soil application, T4: RDF + ZnSO4 @ 0.2% foliar spray twice at 30 and 60 DAS, T5: RDF + Zn-EDTA soil application @ 10 kg ha-1 , T6:RDF + Zn-EDTA foliar spray @ 0.1 % twice at 30 and 60 DAS, T7:RDF + Zn-Humate soil application @ 42 kg ha-1 ,T8:RDF + Zn-Humate foliar spray @ 0.25% twice at 30 and 60 DAS, T9:RDF + FeSO4 @ 50 kg ha-1 soil application, T10: RDF + FeSO4 @ 0.5% foliar spray twice at 30 and 60 DAS, T11:RDF + Fe-EDTA soil application @ 10 kg ha-1 , T12:RDF + Fe-EDTA foliar spray @ 0.1 % twice at 30 and 60 DAS, T13:RDF + Fe-Humate soil application @ 42 kg ha-1 , T14:RDF + Fe-Humate foliar spray @ 0.25% twice at 30 and 60 DAS. Dry matter production gradually increased with advancement in age of crop upto harvest. The highest dry matter production was recorded in treatment receiving RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS in crop at 30DAS, 60DAS and at harvest followed by RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. There was a significant difference among the treatments and the highest grain yield and straw yield was recorded in treatment receiving RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS in crop followed by RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. N,P,K,Fe content in the crop steadily decreased with advancement in age of the crop upto harvest. The treatment receiving RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS recorded the highest nutrients (N,P,K,Fe) content in crop at 30DAS, 60DAS and at harvest followed by RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. N,P,K,Fe uptake in the crop steadily increased with advancement in age of the crop upto harvest. The treatment receiving RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS recorded the highest nutrients (N,P,K,Fe) uptake in crop at 30DAS, 60DAS and at harvest followed by RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. Zn content in the crop decreased with advancement in age of the crop upto harvest. The treatment receiving RDF + Zn Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing recorded the highest nutrient content in crop at 30DAS, 60DAS and at harvest followed by RDF + Zn Humate soil application. Zn uptake in the crop increased with advancement in age of the crop upto harvest. The treatment receiving RDF + Zn Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing recorded the highest nutrient uptake in crop at 30DAS, 60DAS and at harvest followed by RDF + Zn Humate soil application. The grain quality parameters like N, P, K, Fe, protein, calcium, carbohydrate were highest in treatment receiving RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS followed by RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. Zn content in grain was highest in treatment receiving RDF + ZnSO4 @ 0.2% foliar spray twice at 30 and 60 days after sowing followed by RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS. There was a gradual decrease seen in the available N,P,K content in soil from 30 DAS onwards till harvest. The treatment receiving RDF + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS recorded the highest available N,P,K in soil at 30DAS, 60DAS and at harvest followed by RDF + foliar application of Fe-humate twice at 30 and 60 DAS. There was a gradual decrease seen in the available zinc content in soil from 30DAS onwards till harvest. The treatment receiving RDF+ ZnSO4 @ 50 kg ha-1 recorded the highest available zinc in soil at 30DAS, 60DAS and at harvest followed by RDF+ ZnSO4 @ 0.2% foliar spray twice at 30 and 60 DAS. There was a gradual decrease in the available iron content in soil from 30DAS onwards till harvest. The treatment receiving RDF+ FeSO4 @ 50 kg ha-1 recorded the highest available iron in soil at 30DAS, 60DAS and at harvest followed by RDF+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS.en_US
