The article describes the technology of laying a film covering with a specially selected perforation of holes on the laid groove with fastening the edges of the covering along its entire length. Calculations of the irrigation rate are given, which must be strictly observed for economical water use when irrigating along furrows. The use of a perforated polyethylene film screen will provide the required moisture capacity throughout the season. Stabilization of the irrigation regime will ensure high yields while complying with the requirements of the law on environmental protection. The most effective agrotechnical conditions are proposed and recommendations for the growing season are given.

Main Factor

Soybean is one of the most important agricultural crops, which although in general very unpretentious, but under the environments of the Altai Territory (Prialeyskaya steppe) it is almost impossible to obtain consistently high yields due to unfavorable climatic conditions. The main factor in obtaining consistently high yields and involving additional areas for soybean crop in this climatic zone is the use of complex agrotechnical techniques, namely regular irrigation. The purpose of the work was to develop an optimal mode of soybean irrigation under the environments of the Prialeyskaya steppe in the Altai Territory. The possibility of effective soybean cultivation on the irrigated lands of the arid Prialeyskaya steppe in the Altai Territory has been theoretically substantiated and experimentally confirmed in the paper. The regularities of the influence of different irrigation regimes on soybean productivity have been established. The specific water consumption per unit of marketable output has been determined depending on the irrigation regime. The relations of grain yield with the change of irrigation regime have been established. The maximum yield of soybean grain has been obtained in the 80% LMC variant (the lowest moisture capacity), which was 3,3 t/ha in 2016. The average yield for 3 years of research was 3,1 t/ha and exceeded the yield on the control variant by 2,1 t/ha. In the 80% LMC variant but with the treatment of soybean seeds before sowing with an inoculant the average yield was 3,5 t/ha, which exceeded the yield in the control variant by 2,5 t/ha. Also in the 80% LMC variant and with inoculant seed treatment the yield of soybean grain exceeded the yield in the non-treated variant by 0,4 t/ha. Thus, it has been established that to obtain the maximum yield of soybean under the environments of the Prialeyskaya steppe should support the level of pre-irrigation soil moisture at 80% LMC.

Abstract Due to water scarcity and dry Mediterranean conditions, improving water use efficiency is a major challenge for sustainable crop production and environment protection. Field experiments were conducted for two consecutive years (2010 and 2011) to assess the effects of variety and irrigation method on potato crop, following a 2 × 4 factorial experiment type arranged in a split plot design with two spring potato varieties (Spunta and Marfona), and four irrigation methods (drip irrigation with two modes of dripper spacing/dripper flow: 30 cm at 4 l/h and 60 cm at 8 l/h, sprinkle irrigation, and furrow irrigation), with three replicates. Potato was irrigated when soil moisture in the active root depth was within the range of 75-80% of field capacity as determined by the neutron probe technique. Results did not show any differences between both varieties. Moreover, no differences in marketable yield, total dry matter, and harvest index were found between irrigation methods. However, results showed that sprinkle irrigation significantly enhanced nitrogen use efficiency. Furthermore, both water productivity and irrigation water use efficiency were significantly increased under drip irrigation compared with the other irrigation methods. They were about twice those under furrow irrigation, indicating that the employment of drip irrigation method can effectively address water shortage and sustainable potato production, in the dry Mediterranean region.

Agricultural water is a limiting resource in many semi-arid countries of the world due to low precipitation and high evapotranspiration. Installation of water-saving technologies has been implemented in many parts of the world to use water more sustainably. The use of water-saving irrigation technology for cotton-grain crop rotation has not been adequately studied in the Khorezm region of Uzbekistan. This study provides insights into such technology used on irrigated meadow-alluvial soils of the Khorezm region with a groundwater level of 2-3 m. On the basis of the irrigation regime, experimental work was carried out in the cotton field to determine the sustainability of irrigation technology. In addition, it was determined the duration of irrigation and the soil moisture pattern along the length of the furrows with a field moisture capacity of the soil 70-80-60%. The results indicate that regardless of the soil physical properties (light, medium and heavy), applying irrigation for cotton using counter furrows showed the highest yield of raw cotton, i.e. 4.1-4.2 ton/ha, which is 1.1-1.2 ton/ha more compared to traditional furrow irrigation. Moreover, under variable-jet furrow irrigation the yields of raw cotton was amounted at 4-4.1 ton/ha, which is about 0.9-1 ton/ha more compared to traditional method of irrigation. At the same time, about 16-18% of irrigation water was conserved

AbstractIn recent years, it has become popular for some of countries and regions to adapt the system of governance to varied and complex issues concerned with regional development and the environment. Watershed management is possibly the best example of this. It involves flood control, water use management and river environment simultaneously. Therefore, comprehensive watershed-based management should be aimed at balancing those aims. The objectives of this study are to introduce the notion of environmental governance into the planning process, to establish a method for assessing the alternatives and to develop a procedure for determining the most appropriate plan for environmental governance. The planning process here is based on strategic environment assessment (SEA). To verify the hypothetical approach, the middle river basin in the Tokachi River, Japan was selected as a case study. In practice, after workshop discussions, it was found to have the appropriate degree of consensus based on the balance of flood control and environmental protection in the watershed.

Field experiments were conducted to investigate methods of controlling red rice (Oryza sativaL. ♯ ORYSA) in drill-seeded rice (O. sativa). Treatments included the rice cultivar ‘Mars', coated with calcium peroxide (CaO2) at 40% (w/w) and a crop protectant, R-33865 (O,O-diethyl-O-phenyl phosphorothioate) at 0.5 and 1% (v/w). Molinate (S-ethyl hexahydro-1H-azepine-1-carbothioate) at 6.7 kg ai/ha was applied preplant incorporated (ppi). The land was flooded (2.5 to 5 cm deep) after seeding with rice (100 kg/ha, 2.5 cm deep), and the water was maintained throughout the growing season. CaO2, with or without molinate, increased rice grain yield 50% and increased rice culm density fivefold above untreated rice. Molinate applied ppi controlled 96% of the red rice. Rice seed coated with only CaO2or with CaO2plus R-33865 at 0.5%, each combined with ppi molinate, produced 5690 and 6030 kg/ha of grain, respectively. These high yields were associated with red rice control by molinate and good stands of rice provided by O2supplied by CaO2. R-33865 applied to rice seed at 1% (v/w) injured rice by reducing rice culm densities 41%, compared with rice without protectant.

Properties Of Soil

A pot experiment was executed to investigate the impact of biochar and compost with water-saving irrigation on the rice yield, water use efficiency, and physicochemical properties of soil. Two irrigation regimes—namely alternate wetting and drying (AWD) and continuous flooding (CF)—and four types of organic amendments (OA)—namely rice husk biochar (RHB), oil palm empty fruit bunch biochar (EFBB), compost and a control—were applied to evaluate their effects. Under the AWD irrigation regime, the maximum grain was produced by RHB (241.12 g), whereas under the same organic amendments, both AWD and CF produced a similar grain yield. Under the same organic amendment, a significantly higher water use efficiency (WUE) was observed from the AWD irrigation with RHB (6.30 g L−1) and EFBB (5.80 g L−1). Within the same irrigation regime, soil pH, cation exchange capacity, total carbon, total nitrogen and available phosphorus were enhanced due to the incorporation of biochar and compost, while higher soil exchangeable potassium was observed under CF irrigation for all treatments. RHB and EFBB significantly reduced the soil bulk density (up to 20.70%) and increased porosity (up to 16.70%) under both irrigation regimes. The results imply that the use of biochar with AWD irrigation could enhance the nutrient uptake and physicochemical properties of soil and allow rice to produce a greater yield with less water consumption.
