“…As an efficient water‐saving fertilizer application technology that greatly improves the utilization of water and fertilizer resources, drip fertigation helps alleviate water shortages and reduces agricultural fertilizer pollution. Water and fertilizer distribution uniformity are important considerations for the design and operation of drip fertigation systems because non‐uniform applications of water and fertilizer may reduce crop yield (Li and Rao, ; Zhao et al ., ; Wang et al ., ), contaminate groundwater and surface water (Allaire‐Leung et al ., ; Barragan et al ., ) and degrade soil quality (Bracy et al ., ; Wang et al ., ). Several factors such as injector type, pressure difference and lateral layout can potentially affect the water and fertilizer distribution uniformity of drip fertigation systems.…”

The effects of three injector types (differential pressure tank, Venturi injector and water‐driven piston proportional pump), three pressure differences (0.10, 0.15 and 0.20 MPa) and two lateral layouts (longitudinal and transversal) on drip fertigation uniformity were comprehensively evaluated through field experiments. No statistically significant differences in water uniformity were found between injector types or pressure differences, while the influence of lateral layouts on water uniformity was significant (α = 0.05). All affecting factors showed an extremely significant influence on fertilizer uniformity (α = 0.01). Water uniformity was better than fertilizer uniformity, both of which generally decreased with increasing pressure differences. The differential pressure tank produced a lower water and fertilizer uniformity than the Venturi injector and proportional pump. The longitudinal lateral layout produced lower fertigation uniformity than the transversal lateral layout. To ensure both high water and fertilizer uniformity in fertigation systems, a Venturi injector and a proportional pump with relatively constant fertilizer concentration are recommended. When a differential pressure tank is used, the differential pressure should be minimized to mitigate the decrease in fertilizer concentration. The differential pressure tank can give high fertigation uniformity (≥ 90%) comparable to the Venturi injector and proportional pump if the transversal lateral layout is further applied. The research provides scientific guidance for the design and operational management of drip fertigation systems in greenhouse vegetables or field crops. Copyright © 2017 John Wiley & Sons, Ltd.

“…Continuous and extensive investigations on the influence of drip irrigation uniformity on the water, nitrogen and salt dynamics, as well as the crop yield and quality, have been conducted at the WatSave Lab, IWHR, since 2009 to explore the possibility of using a uniformity that is lower than the values recommended by the current standards. These studies were conducted under a wide range of environments from arid to subhumid for typical row crops of cotton, maize and vegetable crops (Zhang and Li, , ; Li et al, ; Zhao et al, ; Guan et al, , ). The soil water contents during the irrigation/fertigation event and during the growing season were continuously monitored using sensors (Hydra Probe, Stevens Water Monitoring Systems, Inc., Portland, Ore., USA; 5TE, Decagon Devices Inc., USA).…”

The use of sprinkler and micro‐irrigation has progressed continuously from being a novelty that was employed by researchers to being widely accepted, efficient methods of irrigation for many crops during the past 30–40 years in China. This paper reviews the studies that have been conducted on sprinkler and micro‐irrigation at the WatSave Lab in the China Institute of Water Resources and Hydropower Research (IWHR) over the past two decades. These studies address several areas of concern and provide partial answers to the questions raised during the application and extension of these relatively new irrigation technologies. With the aim of exploring the consumption of sprinkled water that is intercepted by the canopy, the amount of water interception and the losses were quantified, confirming that sprinkler irrigation is an efficient irrigation method. The standards of sprinkler and micro‐irrigation uniformity were studied with respect to many aspects of water and solute dynamics, environmental effects, and crop yield and quality under a wide range of environments from arid to subhumid climates for typical wheat, cotton, maize and vegetable crops. As a result, new target uniformity values have been recommended. Other studies on water, solute and bacterial transport from normal water and sewage effluent can also be useful in the design, operation, maintenance and management of irrigation systems.

“…Sammis et al (1988) found yields up to 57.1 t/ha, when the planting was made in March, while with the planting delay until April, the yields increased up to 63.2 t/ha. The irrigation of plants increased the total plant mass to 128.50 t/ha, while total yields of heads varied between 68.16 and 72.62 t/ha as shown in a study of Zhao et al (2012).…”

Laczi E., Apahidean A., Luca E., Dumitraş A., Boancă P. (2016) Chinese cabbage is a less known, cultivated and consumed vegetable species in Transylvania, although previous studies have shown that it can be grown successfully in this area. The main purpose of the present research was to underline the effectiveness of various treatments on Chinese cabbage growth, yield and quality of the final product in organic farming system. The treatments included: different fertilisation types, place of the culture and several hybrids. Results showed that all the studied factors had a high influence on cabbage heads characteristics such as length, diameter, and weight, on the number of leaves and also on yield. The best yields were registered when horse manure was used (between 76.50 and 99.30 t/ha), followed by cattle manure (between 76.80 and 93.75 t/ha). A higher yield of better quality cabbage was obtained in a polyethylene tunnel (89.27 t/ha) compared to the open field culture (77.50 t/ha). Hybrid Super provided the highest yield (92.70 t/ha), followed by hybrid Vitimo (86.09 t/ha).
