Investigating the advantages of sub-surface irrigation method in winter wheat productivity

Abstract

Studies have found that the sub-surface method of winter wheat irrigation halves the number of irrigations and reduces the crop water consumption by 970-1015 m3, inter-row treatment procedures, and the consumption of fuels and lubricants. The productivity of winter wheat grain in comparison with the control (without sub-surface irrigation) is increased by 0.9 t/ha, environmental pollution from agrochemicals is prevented. The sub-surface irrigation method in conditions of meadow soils with a groundwater level of 1-3 m and mineralization of 1-3 g/l experimented in this paper and the influence of this method on the development dynamics of winter wheat (Polovchanka) on obtaining high yields was also tested. The number of irrigations increased to 6-7 times instead of 3-4. Therefore, on such lands, we recommend while designing the drainage system, the designers should plan the depth of the drains no more than 1.5 meters. Sub-surface irrigation is a temporary closure of closed drainage during the growing season of winter wheat, leading to an increase in groundwater level (80-130 cm), thereby leading to an increase in the moisture reserve in the soil.

Efficiency of growing cotton with physiological active substance without application of mineral fertilizers in the case of Uzbekistan

“…Due to the fact that Uzbekistan ranks 5-6 among the largest cotton-growing countries in the world and cotton is grown on more than 1.0 million hectares, the cotton crop is exported to more than 30 countries in the form of fiber, yarn and other products and this is of economic importance of the country [1,4].…”

“…In order to increase soil fertility and the efficiency of the use of macro and micro elements in the soil, to stimulate plant growth and development, the physiologically active substance Tevevit Boms is used [3]. The mechanism of action of Tevevit Boms is associated with the improvement of metabolism in the plant and is accompanied by the activation of the activity of the photogorms auxin and cytokine, which regulate natural growth [4,5].…”

Compatibility of ‘soil-variety-fertilizer’ to fertilizer norms and dynamics of food elements

“…The role of soil fertility and high-yielding varieties and modern technologies in improving the well-being of the population, including Uzbekistan, and its appeal to the world community is invaluable [1,8,9]. Today, not only Uzbekistan, but all over the world requires the rational use of land and water resources, their conservation, the provision of the population with environmentally safe food on a global scale.…”

Technology development for the production of soy protein supplements in meat products

“…At present, there is a lack of food rich in easily digestible proteins in the diet of the population. One of the ways to solve this problem is to replace animal proteins with vegetable ones, which are both cheaper and healthier [1]. Soy is the only crop that contains high quality protein.…”

“…On the basis of protein, highly effective protein-vitamin and mineral complexes are obtained -soy protein concentrates, consisting of soy proteins, vitamins, minerals and enzymes [1,9].…”
