Influence of Zn, Fe and B applications on nutrient availability in soil at critical growth stages of maize (Zea mays) in vertisol of Marathawada region of Maharashtra, India

The experiment was conducted during Kharif 2017-18 to study the “Influence of Zn, Fe and B applications on nutrient availability in soil at critical growth stages of maize crop in Vertisol of Marathawada Region of Maharashtra” at the research farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture Badnapur. The experiment was planned in randomized block design with nine treatments with three replications in randomized block design. The treatment consists of T1 RDF (150:75:75 NPK kg ha-1 ), T2 (RDF + ZnSO4), T3 (RDF + FeSO4), T4 (RDF + Borax), T5 (RDF + ZnSO4 + FeSO4), T6(RDF + ZnSO4 + Borax), T7 (RDF + FeSO4+ Borax), T8 (RDF + ZnSO4 + FeSO4 + Borax),T9 (RDF + Foliar application of grade II micronutrient application at 45 DAS).The results emerged out clearly indicated that nutrient availability in soil was increased due to application of micronutrients. It was inferred from the results that application of RDF + ZnSO4 @ 20 kg ha-1 + FeSO4 @ 20 kg ha-1 + Borax @ 10 kg ha-1 found superior over only N P and K application i.e. RDF (150:75:75 N, P2O5 and K2O kg ha-1 ). | Influence of Zn, Fe and B applications on nutrient availability in soil at critical growth stages of maize (Zea mays) in vertisol of Marathawada region of Maharashtra, India
