Abstract

A field experiment was carried out in one of the farms in the district of Al-Suwaira-Wasit governorate for the 2021 agricultural season. To find out the effect of adding levels of NPK and the sites of addition on their concentrations in the vegetative and fruiting part and the productivity of the eggplant crop. The study included three levels of NPK and was given the symbols (C0, C1, and C2) and two places to add fertilizer 10 and 20 cm next to the plant, and they were given the symbols D2 and D1 sequentially. Six treatments were produced from the fertile levels, and the additional distances are C2D2, C2D1, C1D2, C1D1, C0D2, and C0D1; with three replications, experimental units become 18 units. A completely randomized block design (RCBD) was used to distribute treatments. The dry weight and root diameters of the plant were taken, and the NPK concentrations were estimated in the vegetative part at the end of the season, as well as the NPK concentrations in the fruiting part of the first and last fairies and the cumulative yield was taken. The results showed a significant effect of NPK levels on nitrogen and phosphorous concentrations in the vegetative and fruiting parts, while the effect was not significant on potassium concentration. The position of the fertilizer application did not significantly affect the concentration of NPK in the plant. The level of the second fertilization, C2, had a significant effect on the dry weight of the plant. Fertilization levels had a significant effect on root diameter and yield. Keywords: Mineral fertilization, application, NPK, eggplant.
