Abstract
High-quality seeds are the most efficient means of intensifying production and the cheapest factor of the impact on increasing productivity of agricultural crops. The purpose of the study is to examine the impact of fertilization and sowing scheme on the seed productivity of the tomato variety Lehin under conditions of drip irrigation in the Southern Ukrainian Steppe. The experiment was carried using the method of split plots by randomization and four times replicated, in accordance with the methodology of conducting field experiments on improving the elements of the technology of crop production. General scientific (analysis, synthesis, observation, comparison, measurement), special (field, laboratory), mathematical and statistical, calculation and comparison methods were used in the research. On average, over 2016–2018 the maximum productivity of tomatoes was 98.23 t/ha in the variant of a complex combination of organic and mineral fertilizers. The tomato seed productivity was 159.3 kg/ha. Direct positive correlation was established between the fruit productivity and the seed productivity, the correlation coefficient was r=0.92. Under the sowing scheme 50+100 cm the highest tomato productivity indexes were obtained – 74.45 m/ha (fruits) and 144.3 kg/ha (seeds). Any considerable impact of the investigated factors on the seed quality was not revealed.
