Introduction. Rice grawing is an important branch of crop sector in Kuban, which produces about 80% of Russian rice. One of the significant factors reducing the yield of this crop is the presence of high-stemmed weeds growing in the canals and on the rollers of the rice paddy fields. The problem is the lack of structural and technological scheme for the sprayer to protect the rice irrigation system from the reeds providing local treatment of their panicles. When treating the weeds that are on the perimeter of the rice paddy field, the unit is under the influence of disturbances that arise from the unevenness of the relief of the field. These disturbances cause oscillation of the boom in the vertical and horizontal directions, which has a negative impact on the quality of processing the reed panicles. Aim of the Article. The work is aimed at increasing the efficiency of rice paddy fields protection from the reeds by substantiating the design and technological scheme of the sprayer for local treatment of the reed panicles and the model of the sprayer movement according the relief of the rice cheek. Materials and Methods. In theoretical studies, the mathematics and theoretical mechanics methods were used. Experimental studies were conducted on rice irrigation systems of Krasnoarmeiskiy district of Krasnodar region using planning experiments. Results. The design and technological scheme of the sprayer with a right-handed boom, formed according the placement of the reed upper points y = 310,84x0,0955, located in the channel of the paddy field is proposed. Based on the sprayer movement model, the range of boom position variation differs from the regulated value for plowing – 3.1 %; rice stubble – 1.4 %; rape – 0.6 %; clean fallow – 2.3 %; winte r wheat – 1.4 %. Discussion and Conclusion. The obtained data show an insignificant difference in the variation of boom oscillation of the proposed sprayer from the adjustment value, which positively affects the quality and accuracy of treating reed panicles. The obtained results can be used for serial production of sprayers for treating high-stemmed weeds in rice irrigation system and high-growing crops.

Abstract. Different share types of tine type inter-row cultivator are used to remove the weeds and loosen the soil surface between the rows during the first true leaf stage of cotton. The efficiency of these shares can be changed by soil properties and working parameters. Therefore, this study evaluated the effects of different share geometries for a tine inter-row cultivator on weed control and plant growth parameters at three different working depths (100, 150 and 200 mm) and a constant working speed (5.4 km h-1) under cotton planted field conditions. Measurements included the weeding efficiency within row and between rows, the percentage of damaged plants, root dry weight, shoot dry weight, NDVI (Normalized difference vegetation index), SPAD (the relative content of chlorophyll) values and seed cotton yield. The results indicated that the inter-row cultivation at the first true leaf stage of cotton significantly increased the plant growth parameters (root dry weight, shoot dry weight, NDVI, SPAD) and seed cotton yield. The share types had a strong effect on the weeding efficiency and the percentage of damaged plants. The increased working depth increased the weeding efficiency, plant growth parameters and seed cotton yield, but also significantly increased the percentage of damaged plants. Overall, the results from this study suggest that the inter-row cultivation during the early stage of cotton will be an effective approach in improving the weed control and the plant growth in cotton production. These outcomes depend on the share type and working depth of the tine type inter-row cultivator.

It was shown that soil is a specific type of natural resource that can be renewed when reasonably cultivated by various tillage methods. It requires the availability of working bodies that meet the qualitative agrotechnical indicators of the technological process. (Research purpose) To improve the design of the working body meeting the qualitative agrotechnical indicators of the shallow tillage technological process. (Materials and methods) The main agrotechnical indicators of the cultivator's working body were determined. (Results and discussion) It was proved that the working bodies developed at the Agrarian Scientific Center "Donskoy" meet the agrotechnical requirements for the indicators of the shallow tillage technological process in terms of the crumbling quality: the content of fractions less than 25 millimeters in size in the treated soil layer is 81-92 percent in terms of quantitative composition. It was found out that the highest quality of seam crumbling during the shallow tillage process with a predominant content of fractions less than 25 millimeters in size (on average 90-91 percent) was made possible with the help of a working body with a 30-degree rack sharpening angle. It was determined that at the same time the share of erosive dust-like particles increased by 1.3-3.0 percent, which is unacceptable due to the agrotechnical requirements for shallow tillage. (Conclusions) Working bodies with a rack sharpening angle of 50 and 70 degrees and a paw opening angle of 94, 104 and 114 degrees compile with agrotechnical requirements for all qualitative indicators of the shallow tillage technological process and can be applied as anti-erosion ones when used in the combined units equipped with a device for mulching the surface soil layer on stubble backgrounds without preliminary processing.
