In the 1:1 (cotton:grain) system of short-rotation, soybean, bean, mung bean crops were harvested as a repeat crop after winter wheat. Their stem crop and mixed siderate crops (perco, oats, green peas) were planted in the second half of August, and the blue mass crop grown in October-November was harvested for livestock. The lower 15-20 cm part of the stem was plowed under the plow as a blue manure, at the end of one rotation, the amount of organic carbon in the soil increased by 0.041-0.073%, and the total nitrogen content by 0.012-0.016% compared to the initial values. The highest rate of dry mass accumulation of cotton was observed when using short-row rotation 1:1, winter wheat + mixed siderate crops (perco, oat, green pea):cotton system. The dry mass of the leaves of the Navroz variety of cotton was 22.6 g, the dry mass of the stem was 33.4 g, the dry mass of the bolls was 18.5 g, and the dry mass of the cotton was 48.0 g. The total dry mass of 1 plant was equal to 122.5 g. In the 1:1 (cotton:grain) system of short-rotation, when cotton was grown as a repeat crop after legume-cereal (soybean, mung bean) and mixed siderate (perco, oat, green pea) crops, it provided a higher and better quality cotton yield. Cotton yield was 3.2-5.8 tons/ha, fiber output was 1.0-1.5 percent, and 1000 seed mass was 9.0-11.0 g/ha. Besides, the length of the fiber was found to be higher by 1.4-2.0 mm.

Soil salinity has enormous negative impact on crop productivity leading to food insecurity and malnutrition, especially in arid regions. A field experiment was conducted during the summer seasons of 2018 and 2019 to evaluate the effects of various N fertilization rates in combination with Bradyrhizobium japonicum inoculation on the agronomic perfor-mance of soybean (Glycine max L) in saline soils (EC 5.8 dS m-1). The following fertilization treatments were applied: no fertilization (control), N0Р90К60, N30Р90К60, N60Р90К60 individually and in tandem with B. japonicum as a seed bio-inoculant. The experiment in a split-plot design, N fertilization as the main plot, the seed inoculation as the sub-plot was set up in three replicates. Soybean growth, nutrients uptake and yield parameters increased with increasing N fertili-zation rate, however, the effect was more pronounced with the seed inoculation. Averaged over the cropping seasons, the soybean yield was higher by 20.4%, 19.0%, 34.1% and 6.1% in the inoculated treatments of no-fertlization, N0Р90К60, N30Р90К60, N60Р90К60, respectively as compared to the similar fertilization treatments without the seed inoculation. As a result, fertilization rate of N30Р90К60 in with association B. japonicum inoculation was recommended as this study outcome due to the high soybean yield and quality seeds as the crucial components of sustainable agricultural production under salt-stressed field conditions.

Abstract This article provides information on the results of scientific research aimed at maintaining and increasing soil fertility in the country and in the world today, as well as ways to increase it, as well as the impact of organic fertilizers on soil fertility. The article presents evidence-based data on the study of the effect of soybean, mung bean and oat sowing in different ways with deep, medium and shallow tillage after harvesting winter wheat in conditions prone to wind erosion with low fertility, on the mechanical composition of light irrigated meadow saz, slightly saline soils for the number of bacteria accumulating nitrogen in the roots of legumes and root crop residues macroaggregates in the soil between the options increased by 0.1-10%, soil porosity by 0.6-1.5, humus content by 0.001-0.004%, total nitrogen by 0.005%, the content of nitrate nitrogen by 0.1-3.6 mg/kg. In the variants with row crops of soybean and mung bean after tillage to a depth of 30 cm after winter wheat, the yield of mung bean grain was 16.5 c/ha, and soybean 18.8 c/ha, where the mung bean yield was higher by 2.1 c/ha, and soybeans by 2.5 c/ha compared with chisel treatment to an average depth of 22-24 cm. tillage to a depth of 14-16 cm using a cultivator. With ordinary sowing, mung bean achieved a profitability of 48.1%, and soybeans 52.7%. When growing cotton next year against the background of row sowing of repeated crops of mung bean and soybeans with a plow to a depth of 30 cm after harvesting winter wheat, the yield from cotton sown after mung bean was 33.4 centners / ha, and after soybeans 34.2 centners / ha and the level of profitability increased by 39.5%.

Abstract The presence of 0.411% nitrogen, 0.152% phosphorus, 0.209% potassium in the root part of winter wheat, also the presence of 0.207% nitrogen, 0.116% phosphorus, 0.137% potassium element in the stubble part, 1.21% nitrogen, 0.32% phosphorus, 0.5% potassium the root part of legumes, 0.39% nitrogen, 0.2% phosphorus, 0.71% potassium the stubble part, 1.25% nitrogen, 0.88% phosphorus, 1.1% potassium the root part of the bean, 0.86% nitrogen, 0.32% phosphorus, 1.1% potassium the stubble part, 1.38% nitrogen, 0.90% phosphorus, 1.0% potassium the root part of the mung bean, 1.22% nitrogen, 0.29 phosphorus, 1.3% potassium in the stubble part and 0.90% nitrogen, 0.33% phosphorus, 0.99% potassium in the root part of mixed siderite (perco + oats + green peas), 0.61% nitrogen, 0.22% phosphorus and 0.68% potassium the stubble part were found in this research. If the total remnant of stubble and root was 2.74 tons/ha when the norm of mineral fertilizers was N180P125K90 kg/ha in winter wheat, in the case of soybean cultivation as a secondary crop, the norm of mineral fertilizers in winter wheat was N180P125K90 kg/ha+15 tons/ha in the soybean with the use of organic-mineral compost was 2.96 tons/ha, which is 0.22 tons/ha higher than in the background with only mineral fertilizers were observed that 31.1–44.9 kg/ha of total nitrogen remained after soybean per 1 ha. It was found that the norms of mineral fertilizers used in the treatment and care of nitragin before sowing the seeds of mung bean and soybeans grown as a secondary crop after winter wheat affected the amount of root and root residues that left the plants in the soil, 0.73-0.93 tons/ha of roots in the soil, 1.30-1.49 tons/ha of sorghum and 0.81-1.04 tons/ha of roots and 1.70% of soybeans grown as secondary crops, 1.92 tons/ha of ore residues were found to remain.

Inoculation of seeds of legumes (soybean - Glycine max L., mung bean - Phaseolus aureus L., wild beans - Phaseolus) grown as a secondary crop after winter wheat before sowing with nitragin and application of mineral fertilizers in different doses affected the amount of endogenous bacteria formed in the plant root as well as the agrochemical properties of the soil. Inoculation of legume seeds with nitragin before sowing and application of mineral fertilizers at different rates increased the amount of humus in the topsoil (0-30 cm) layer by 0.025-0.029% compared to the initial values, and the total nitrogen content by 0.009-0.012%. The formation of endogenous bacteria in the root of the plant was inoculated with nitrogen before sowing the seeds of soybean, moss, bean crops. The amount of legumes was 22.7-36.7 pieces in the variant, in which the mineral fertilizers N30 R90 K60 kg/ha was applied, whereas it was 12.0-15.6 pieces in the variant without any mineral fertilizers.
