چکیده
The paper presents the materials of field research on study regularities development moisture outlines light soils during drip irrigation vegetable crops. correlation is found between depth moistened layer and area moistening pre-irrigation threshold content active soil layer, standards flow rate drippers, which gives an opportunity to decline unproductive water consumption for filtration. It that in loamy sandy loam chestnut soils, guaranteed rule regime, onion crops, it essential maintain 80% HB with 200 m3 / ha outlets 2.8 l h, 120 m3/ha discharge 1.7 l/h, correspondingly. In tomatoes grown light-loamy light-chestnut appropriate apply 180 ha, provides level humidity 0.6 m not lower than HB, formation required characteristics contour (depth 0.62 diameter 0.37 m), as well enhance efficiency use by 11.1%. results can be applied design systems

Traditional and New Approaches to Irrigation Scheduling in Vegetable Crops
Intensive vegetable cropping systems use large amounts of water and nutrients. Excess application of water and nutrients results in economic losses (higher fertilizers and pumping costs) and contributes to nutrient leaching and environmental degradation. Increasing nutrient use efficiency (NUE) and water use efficiency (WUE) should be a priority for sustainable horticulture. This increased NUE,...
متن کاملInfluence of Drip-irrigation Method on Performance and Yields of Cucumber and Tomato
The conservation of water is crucial to sustainable agricultural production in areas of low rainfall or uneven precipitation distribution. Under such circumstances, drip irrigation methods offer a useful option for economic production of vegetable crops. This preliminary study examined the efficacy and performance of two drip irrigation methods on cucumber and tomato crops grown out of season. ...
متن کاملEffects of salinity and irrigation water management on soil and tomato in drip irrigation
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
متن کاملIrrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...
