Abstract

The article presents the results of the study of the influence of the nutrient regime on the typical black soil of a humus-type soil on the dynamics of the development of plants of the bee-pollen hybrid Janos F1. The influence of the use of organic and mineral fertilizers on the dynamics of content in the arable layer of ammonia and nitrate form of nitrogen, mobile phosphorus and exchangeable potassium is investigated. According to the results of the data analysis, the mathematical relationship between the number in the period of mass flowering and fruiting of the lateral shoots and the provision of plants at the beginning of vegetation by mobile phosphorus (r = 0.69-0.76) and exchangeable potassium(r = 0.45-0.65). Biometric indices have been established that play an important role in the formation of commercial yield of cucumber seeding bee pollen hybrid Janos F1. The correlation analysis revealed a mathematical relationship between the fruit yield and the number of leaves, the leaf area on the plant (r = 0.95), and the number of first-order side shoots (r=0.94). The highest commodity yield of cucumber provides for the consistent use of Agrovit-Kor 1.5 t/ha + N30Р24К24- 35.9 t/ha, on average, during the years of the experiment, the increase in commodity yields for the combined use of fertilizers was relative to control (without finishing) 49.6 %, reference N30R60 K45 (locally) 14.3 %
