 ABSTRACT

In addition to the macronutrients (N, P, K, Ca, Mg and S), micronutrients (Fe, Mn, Zn, Cu, B and Mo) are required for optimal plant growth. In India deficiencies that occur are related to specific crop requirements and soils and are wide spread. For evaluation, correction of wide spread deficiencies of micronutrients and to emerge a viable nutrient recommendation to maize crop a  field experiment was conducted during the kharif season of 2015 in the sandy loam soils of Agricultural College Farm, Mahanandi, Andhra Pradesh. The objective of the study was to identify the micronutrients uptake by maize and the effect on grain production, and to recommend micronutrients that would improve the quality and quantity of the produce. No significant yield advantage was found between the recommended amounts of major plant nutrients of nitrogen (N), phosphorous (P2O5) and potash (K2O) at a rate of 250:60:60 kg per hectare and the various combinations of secondary and micronutrients.  Application of recommended dose of fertilizers with 0.1 per cent ZnSO4 showed the significant effect on uptake of micronutrients by maize crop. Response of maize to micronutrients was consistent, where amount of N, P, and K were adequate in the leaf samples. Diethylene triamine penta acetic acid (DTPA) extractable Zn was found to be below the critical level while Fe and manganese (Mn) were adequate. Zinc content in maize leaf was deficient, whereas Cu and Mn were in the normal range and Fe was in excess.

Key words: Maize, Micronutrients, DTPA and Uptake.
