Nutrient removal and yield of different maize hybrids
Objective: to determine the macro and micronutrient removal values and potential yield of different hybrids, and, also to determine the relationship between grain nutrient removal and grain yield. Design/methodology/approach: to assess correlations and determine the association degree between the nutrient removal values and grain yield. Results: the total nutrient removal values were in N> K> Ca> Mg> P, and Mn> Fe> Zn> B> Cu order, which are higher values when compared to another research. Also, these provide the mineral content in grains, which is a nutritional quality-related parameter. Limitations on study/implications: increasing the number of hybrids, different fertilization rates, different soil conditions, and crop management practices should be evaluated to assess whether these influence/inhibit the final nutrient concentration and total removal in grain. Findings/conclusions: The total grain nutrient removal values varied as a function of hybrids, yield goal, and nutrient concentration in tissues. These values allow the adjustment of current fertilization rates. The same hybrids under different management practices (fertilization dose), or soil types, substantially influence the grain nutrient concentration and therefore total nutrient removal.

Findings/conclusions: The total grain nutrient removal values varied as a function of hybrids, yield goal, and nutrient concentration in tissues.
These values allow the adjustment of current fertilization rates. The same hybrids under different management practices (fertilization dose), or soil types, substantially influence the grain nutrient concentration and therefore total nutrient removal. |
