The effect of fertilization on the development and productivity of cotton (Gossypium hirsutum L.) when growing by the seedling method

Abstract

Introduction. In the last decade, cotton has increasingly attracted the attention of not only researchers, but also farmers of the Lower Volga region and other regions of our country. This is due to the fact that Russia does not have its own raw materials of this strategically important crop. Therefore, the development of cotton production has good prospects in the southern regions of our country. For the further development and intensification of cotton growing in the Volgograd region, it is necessary to develop not only methods of agricultural techniques for growing cotton with high commodity indicators, but also to solve a number of logistical issues. Object. Cotton seedlings. Materials and methods. A scheme has been developed for a laboratory experiment using mineral (0.4% solution of compound fertilizer 350 ml/0.5 l of soil) and organic top dressing (zoohumus 5 g/0.5 l of soil) when growing cotton seedlings, with further observations in the open ground. Results and conclusions. The use of fertilizing at the early stages of the development of cotton seedlings has had a positive effect, including during its further cultivation in the open ground. A significant increase in yield was obtained due to higher plant preservation and improvement of their morphometric parameters. The profitability of using pet humus in the early stages of seedling development exceeded the control by 149.4% and by 135.2% – the option with the use of mineral fertilizers. Further study of the possibility of using zoohumus as a plant growth stimulant is required.
