Subsurface drip irrigation success depends on surpassing the backpressure obstacle, a phenomenon which occurs when water application intensity exceeds infiltration rate of soil, reduces emitter flow rate. Thus, this study aimed to determine variation, in relation surface flow, four emitters buried at two depths loam soil (Yolo Loam soil), and generated by subsurface condition. The cavity radius...

In the absence of suitable specialized models to simulate soil wetting patterns in subsurface drip irrigation systems considering hydraulic conditions along laterals, a new model was developed and named “comprehensive model” this study. This couples lateral characteristics with properties utilizes Hydrus-3D software as complementary section front beneath lateral. To evaluate model, three 16 mm ...

Highlights Subsurface drip irrigation (SDI) has continued to expand in area within the U.S. during last 15 years. Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, turf). usage on many crops matured through research development of appropriate strategies technologies Despite some persistent challenges successful use SDI, important opportunities...

Due to rising food demand and the limitation of water resources, achieving security is essential. The lettuce crop affected when grown under limited supplies as it produces small heads, especially during late growing stage. For this reason, important maximize use efficiency productivity. Two successive experiments were conducted 2021 2022 reduce losses via deep percolation using a geotextile la...

A 4-year study was conducted to establish the effects of drip irrigation configuration and rate on fruit yield and quality of young highbush blueberry plants (Vaccinium corymbosum L. ‘Duke’). Plants were grown in a silt loam soil on raised beds and were non-irrigated or irrigated using either one or two lines of suspended drip tape. Each line configuration had in-line emitters spaced every 0.3 ...

Agriculture is the economic sector that consumes around 70 % of total water extracted globally, considering itself a victim its own inefficiency. The present work was oriented to look for irrigation alternatives allow greater productivity water. trial carried out at Faculty Agricultural Sciences, Technical University Machala, Ecuador. amount applied corn crop through furrow and drip evaluated. ...

Potatoes are a high-value crop with shallow root system and high fertilizer requirements. The primary emphasis in potato production is minimizing nitrogen-leaching losses from the zone through fertigation. Therefore, field experiment was conducted for two consecutive years, 2018–2019 2019–2020 to assess effect of nitrogen irrigation amount frequency on tuber yield, water balance components prod...
