Experience has shown that by increasing the grip width it would be possible to reduce the intensity of rain while maintaining labor productivity, which is achieved by studies using the proposed newly developed spouts installed on the ISAD sprin-kler, which provides a relatively low rain intensity, which is explained by the desire to create a microclimate for plants with low water consumption with limited geometry of the irrigated areaThe experimental work that we carried out here at the accepted research facilities in Terter, Zagatala and Ganja on the irrigation of soya, sugar beet, corn and tobacco allows us to give an approximate average rain intensity (mm/min) at an irrigation rate of 300-500 m3/ha, depending on the soil: Sandy -0.3 0.4, light loamy -0.2, 0.3

If we look at the existing irrigation methods used today in the country, then they are divided into: ground, rainfall, underground or underground, drip and spray. Basically, they are transferred to the irrigation field in two forms: through gravity and pressure irrigation systems. Naturally, a gravity irrigation system is economically more expensive than a low pressure irrigation system. However, from a performance appraisal stand point, pressure irrigation methods are less efficient and have serious disadvantages

In Afghanistan, water is mostly used for agricultural purposes. The water supply chain requires updating to ensure its sustainability. Different irrigation methods – such as surface water based irrigation (via canals), groundwater based irrigation, and the Karez irrigation system – are applied across the country. Considering the compatibility of the Karez system with the environment, it can be deemed the most effective irrigation scheme, as it allows collecting a significant amount of groundwater and conveying it to land surface via sub-horizontal tunnels using gravity. This article analyzes Afghanistan’s Karez irrigation systems currently feeding water to over 170,000 ha of farmland with a potential to expand and become a component of sustainable water supply chain.

Purpose: development of a computer algorithm for a quantitative assessment of the hydraulic parameters of an irrigation and drainage system with the possibility of integrating different irrigation methods. Materials and methods. The design of structures for combined irrigation is based on hydraulic calculation. A feature of such systems is the ability to change irrigation methods, which is associated with a significant change in hydraulic parameters and the complication of hydraulic design of structures. Automation of hydraulic calculations based on a universal computer algorithm is the most acceptable way to solve the problem and the basis for designing combined irrigation systems. Results. A feature of the proposed algorithm for determining the quantitative parameters of the combined irrigation system is the use of a step-by-step approach followed by the formation of a generalized hydraulic screenshot of the entire structure. A screenshot of hydraulic parameters here means a quantitative assessment of hydraulic indicators for all nodal points of a structure, implemented by a calculation method for given, stationary modes of system operation. A set of this kind of static screenshots allows you to evaluate the process in dynamics, as well as to carry out comparative assessments of hydraulic parameters under different operating modes of the combined irrigation system. The algorithm offers an original way to identify objects based on the use of a linear coordinate system. The method makes it possible to organize an enumeration of the structural elements of the system and a step-by-step calculation of hydraulic parameters from the inlet section of the design segment to any given nodal point. Conclusions. The calculation results according to the proposed algorithm make it possible to form a specially organized data array, which is a set of symbolic-numeric values that determine the pressure level and water flow rate and identify them with the nodal point of the system.

Preserving the sustainable agriculture concept requires identifying the plant response to the water regime and rationing the water for irrigation. This research compares different irrigation designs coupled with a parametric evaluation system on soil water erosion and soil suitability to assess the sites vulnerable to soil erosion based on a soil water erosion model (ImpelERO) in an area of 150.0 hectares, Ismailia Governorate, Egypt. Land suitability maps are prepared using the Geographic Information System (GIS), and the soil properties are analyzed and evaluated for the different surface, sprinkler, and drip irrigation methods. The results show that the sprinkler and drip irrigation strategies are more practical irrigation methods and additional environment friendly than surface irrigation for enhancing land productivity. Moreover, the principle acumen for creating use of the surface irrigation on this space is for lowering the soil salinity. Land capability index for surface irrigation ranges from 20.5 to 72.2% (permanently not suitable N2 to moderately suitable S2); and the max capability index (Ci) for drip irrigation was 81.3% (highly suitable-S1), while the mean capability index (Ci) was 42.87% (Currently not suitable-NI). The land suitability of the study area using sprinkler irrigation was ranked as highly suitable (S1), moderately suitable (S2), marginally suitable (S3), and currently not suitable (N1). Thus, the obtained data indicated that applying drip irrigation (trickle irrigation) was the most efficient system compared to the sprinkle and surface irrigation systems. To identify the soil, water erosion vulnerability, and soil optimal management strategies for the agricultural parcel in that region, the ImpelERO model (soil erosion vulnerability/impact/management) was applied. Erosion risk classes ranged from V2 (small) to V3 (moderate), that that region categorized as small-sensitive to water erosion by alfalfa, to moderate-sensitive to water erosion by olive. The results of soil losses varied from 7.1 to 37.9 t ha−1 yr−1 with an average of 17.7 t ha−1 yr−1. Thus, guarantee efficient water use and soil suitability for food production in the future will require the use of an efficient irrigation system.
