Effect of synergism on uptake of macronutrients at phenological stages of maize
Author(s): Maize, secondary nutrients, micronutrients, and uptake
Abstract: Decision support for nutrient application remains an enigma if based on soil and plant nutrient analysis. If the crop could be used as an auxiliary indicator, the plant nutrient status during different growth stages could complement the soil test, improving the fertilizer recommendation. Variation of macronutrient level uptake of maize plant was studied at three different stages of growth namely 30, 60 and 90 days after planting. The objective of this study considers the temporal variation of the nutrient uptake rate, which should define crop needs as compared to the critical content in soil solution. Results obtained in this study show that the Requirement of essential nutrients for yield maximization of Pioneer Hybrid Maize 3369 was studied under field condition. The highest grain yield of maize of 4.8 t/ha was obtained with the application of micronutrient mixture along with recommended NPK. The levels of macronutrients in the plant were found to increase from early stage to the later stages of growth and the accumulation of nutrients is much faster from the first to the second stages of growth is much when compared with later stages and remaining constant or decreased within period.
