The influence of various doses of mineral fertilizers and biologically active substances on the yield of Dutch indeterminate tomato Torero in the conditions of BRB APK LLP, Almaty region

Abstract

Tomato is one of the main vegetable crops. Tomato occupies about 2.7 million hectares in the world. The share of the crop in global vegetable production is 14.3% 4 . The main advantages of tomato are its high content of vitamins, minerals, organic acids, carbohydrates and especially carotenoids, which are so necessary for the normal functioning of the human body. Every year the area under tomato grows, its growing technology is improved, in particular, new industrial technologies for its production are developed, and profitability increases. A balanced mineral nutrition system plays a major role in increasing tomato yields. Recently, the size of greenhouses in our country has increased dramatically. According to the information of the RK ASM, the area of greenhouse vegetables is currently 576 ha. 230 ha of it is a high-tech greenhouse. Although the total production of greenhouse vegetables has reached 90,000 tons, it covers only 69% of the domestic needs of the country during the summer season.

For this reason, the government is creating the necessary conditions for the development of the production of dairy products and reducing the amount of taxes. Currently, the consumption of fresh and processed vegetable garden products in the country is on average 3.2 million tons per year. In it, the share of tax is about 7%. Cultivation of vegetable crops in a greenhouse is one of the most developing branches of agriculture today. Therefore, studying the timing, type and quantity of mineral fertilizers, especially biologically active substances, allows to obtain a high yield from the tomato crop. The role of biologically active substances in the quality of the product is more important than other nutritional elements. Therefore, one of the main elements of tomato cultivation technology is the use of fertilizers with rational biologically active substances that ensure high quality and productivity.
