abstract:
The objective of the study was the determination of the reaction of maize varieties, expressed by their ability of mineral component uptake in the initial stage of development to the method of fertilization and term of sowing. Row fertilization increased the content of phosphorus and nitrogen as well as decreased the content of potassium and calcium in dry mass of above-ground parts of plants in the stage of 4-5 leaves, in comparison to broadcast fertilization. The medium late variety, Marignan, took up the most P, N, K, Mg, and Na. The uptake of all analyzed mineral components by maize increased with delay in the time of sowing from 12th April till 10th May. Row fertilization increased the uptake of P, N, K, Mg, and Na in comparison to broadcast fertilization.
