Abstract:
An investigation entitled “Effect of soil and foliar application of Fe and Mn on nutrient content and uptake by upland rice varieties” was carried out during Kharif 2017 and 2018 at Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola in kharif season. Three upland paddy varieties were tested with seven nutrients levels applied in soil as well as by foliar application of Fe and Mn at flowering and dough stage. The experiment was conducted in factorial randomized block design with three replications. Half dose of N with full dose of P & K along with 25kg Fe and 5 kg Mn was applied at the time of sowing in soil. The remaining quantity of N was applied one month after sowing. Foliar application of Fe and Mn was done at flowing and dough stage for upland rice. Result revealed that, maximum grain yield (3223kg ha^-1 and 3520 kg ha^-1), straw yield (6858 kg ha^-1 and 7037 kg ha^-1) and biological yield (10082 kg ha^-1 and10556 kg ha^-1) were recorded by variety Avishkar and found significantly superior over other varieties. Among the treatments, the application of RDF with FeSO₄ + MnSO₄ (25+5 kg ha^-1) in soil recorded significantly higher grain yield (2880 kg ha^-1 and 3469 kg ha^-1) of rice and straw yield, biological yield as well as harvest index. It was found at par with alone application of FeSO₄, MnSO₄ with RDF in soil as well as RDF + Foliar spray of FeSO₄ @ 1.0% and MnSO₄ @ 0.5% at flowering and dough stage during 2017 and at par with RDF + FeSO4 @ 25 Kg ha^-1 (N₂) during 2018. Significantly increased the N, P, K, Fe and Mn contents in grain and straw were observed by combine application of Fe and Mn in soil with RDF. With respect to nutrient uptake, significantly higher uptake of N, P, K, Fe and Mn by grain and straw was registered in Variery Avishkar with combine application of Fe and Mn with RDF in soil. Several workers have reported that, the combine role of Fe and Mn in plant nutrition is much more important than their individual roles (Karim & Mohsin, 1964). Response to growth Fe and Mn in growth and nutrition of the rice plant has been reported (Chiu, 1967, Alam 1982).
