Factors increasing productivity of aubergine under seedless cultivation in irrigated conditions of Astrakhan region

Relevance. To increase the yield of aubergine, a number of agrotechnical methods have been studied. In the conditions of the Astrakhan region, one of the methods is the cultivation of aubergine without seedlings, in which it is very important to select varieties adapted to these conditions, suitable for the duration of the growing season. Cultivation of aubergine without seedling method, in comparison with seedling method, allows to exclude material and technical costs for growing seedlings. To increase the productivity of selected varieties, an important agronomic technique is the use of plant growth regulators that increase plant resistance to unfavourable environmental factors and have a stimulating effect on plant growth and development. Material and methodology. In conditions of Astrakhan region on alluvial-meadow, medium-loamy soils with granulometric composition were carried out studies to identify varieties that are best adapted to these natural-climatic conditions and give the highest yields in seedless cultivation. In the second experiment on seedless aubergine the effect of growth regulators on plant productivity was studied using preparations -Melafen, BP, Gibbersib, P, Biodux, Zh, Epin extra, R.
