The article presents the main results reached in our study of the influence of mineral fertilizers and growth regulators on the individual grain productivity of field pea varieties in the conditions of Western forest-steppe.
The experimental part of the work was carried out during 2016-2018 in the experimental field of the Training and Production Center "Podilya" at the State Agrarian and Engineering University in Podilya. The field experiment was laid down in the research ten-digit crop rotation. Soil of the experimental field is the typical black earth, characterized as deep, low-humus, and heavy gravel on forest-like loams.
The best results for most indicators were obtained in combinations of mineral fertilizers at a dose of N30P30K45 and Vympel growth regulator. It was observed that the Fargus variety had the highest plants of pea sown (92 cm). The largest number of flowers was noted in the Gotovsky variety and amounted to 13.6 pc per plant, and the best indicator of the achieved beans was 82.7% in the Chekbek variety in the same variant.
