The article presents the results of research conducted during 2016-2019 on the impact of different rates of mineral fertilizers and by-products of the predecessor on the content of chemical nutrients in plants and the yield of maize hybrids in the Forest-Steppe. The aim of the research was to establish the peculiarities of nitrogen, phosphorus and potassium accumulation in maize plants in ontogenesis in relation to the yield of hybrids of early and middle-early maturity groups to optimize the mineral nutrition of the crop. The research was conducted on dark gray wooded soil using field, chemical, calculation-weight and mathematical-statistical methods. According to the stages of growth and development of BBCH, the peculiarities of the dynamics of nitrogen, phosphorus and potassium content in plants of hybrids with FAO 190 and 280 depending on the agrochemical load of growing technology are established. Varietal regularities of concentration of chemical elements in maize plants in connection with the accumulation of dry matter by crops in ontogenesis and yield were revealed. Hybrids with the corresponding genetically determined level of nitrogen, phosphorus and potassium content in plants have been identified and its influence on the realization of genotype productivity potential has been shown. The decisive role of potassium and nitrogen in the formation of the corn crop on dark gray wooded soil has been experimentally proved and confirmed on the basis of statistical and correlation analyzes. All hybrids were characterized by high tightness of correlations between yield and content in plants of nitrogen (r = 0.760–0.934) and potassium (r = 0.755–0.943) during the growing season as opposed to phosphorus, where these connections were of medium strength (r = 0.334–0.589) and only partially close (r = 0.702–0.806). According to the results of plant diagnostics of mineral nutrition of plants, the most effective growing technologies with different agrochemical loading are singled out, which ensure the yield of early and middle-early maize hybrids in agro-climatic conditions of the Forest-Steppe at 9.56–10.39 and 11.21–12.10 t/ha.

This study aimed to analyze the influence of inoculation methods with Azospirillum brasilense in morphometric and nutritional parameters of the maize crop. Maize plants, hybrid Formula VT®, were grown under different forms of inoculation: absence of inoculation; seed inoculation; leaf inoculation; seed inoculation associated to leaf inoculation. In the phenological stages V8 and VT the parameters number of leaves, aerial height, root volume, stem diameter, besides the leaves, stem, sheath, root and total dry mass and the leaf content of nitrogen, phosphorus and potassium were determined. In the R6 stage, in addition to the previous evaluations the following parameters were determined: ear diameter and length, number of kernel rows, number of kernels per row, the reproductive structure and thousand grains dry mass, and total number of grains, besides the grain’s content of nitrogen, phosphorus, and potassium. The SPAD index from the leave’s apex, medial and basal thirds was measured fortnightly. The inoculation methods with A. brasilense had little influence in maize’s morphometric and nutritional parameters, also not influencing in production. Maize plants inoculated with A. brasilense, via seed and via seed associated to leaf spraying, positively stood out for the stem diameter, leaves dry mas, root volume, and for the nitrogen, phosphorus, and potassium leaf content.
