TL;DR: In this article, the authors used a Probit regression model to identify and analyse the determinants for the adoption of two soil and water conservation techniques, the "zai" and the "stone strip".

TL;DR: In this article, the evapotranspiration (ET), evaporation (E), growth, yield and water use efficiency (WUE) of plastic-mulched spring wheat with hole planting in 1990 and 1991 under full and deficit irrigation at Zhangye Station of Water-saving Agriculture, Gansu Academy of Agricultural Science in northwest China.

TL;DR: In this article, a study was conducted for three growing seasons at the Wuqiao Experiment Station of China Agriculture University to optimize irrigation scheduling for high wheat yield and water use efficiency.

TL;DR: In this article, four different levels of drip fertigated irrigation equivalent to 100, 75, 50 and 25% of crop evapotranspiration were tested for their effect on crop growth, crop yield, and water productivity.

TL;DR: In this paper, the effect of sprinkler irrigation on the meteorological variables and on the estimates of reference evapotranspiration was investigated under day and night operation conditions for solid-set and moving lateral configurations.

TL;DR: In this article, the effect of shallow water tables on crop water requirements was investigated at Lahore, Pakistan, where lysimeters were connected to bottles with Marriotte siphons to maintain the water tables at the desired levels and tensiometers were installed to measure soil water potential.

TL;DR: Growth parameters, leaf area index (LAI) and dry matter accumulation, have been shown to be sensitive to water stress caused by the deficit irrigations, however, growth parameters were found to compensate for water stress at early stages, while at seed maturity the compensation ability was decreased.

TL;DR: In this paper, the authors investigated the changes in soil water content, NO3-N and salinity within a 150 cm deep soil profile in four different types of farmlands: spring wheat (W), maize (F), spring wheat-maize inter-planting (FW-M), and sunflower (F-S).

TL;DR: In this paper, the water requirements of four major horticultural crops grown in an unheated plastic greenhouse located in Almeria, Spain, were investigated and a simple K c model based on thermal time for greenhouse crops with and without pruning, was proposed and validated.

TL;DR: In this article, the effects of four irrigation water salinities (0.25, 2.5, 5, 10 dS m -1 ) and three potassium fertilizer levels (0, 5 and 10 mmol I −1 ) on yield and some quality parameters of a native Central Anatolian tomato species (Lycopersicon esculentum) were investigated under greenhouse conditions.

TL;DR: In this paper, a GIS-based decision support framework that integrates field scale models of these processes for assessment of non-point-source pollution of groundwater in canal irrigation project areas is presented.

TL;DR: In this paper, a short-term conditional prediction scheme of drought classes is tested using Markov chain modelling. But, the persistence of recent climate conditions tend to dominate, so limiting the prediction capability of Markov chains modelling.

TL;DR: In this article, the authors investigated the impact of irrigation under surface irrigated cotton in Queensland and showed that substantial reductions in deep drainage are possible by ensuring that irrigation applications do not exceed the soil moisture deficit.

TL;DR: In this article, the human impact on land degradation through the integrated effect of fertilization and irrigation on secondary salinization for the different cropping patterns and agro-climatic zones of Lebanon is reviewed.

TL;DR: In this paper, Salinity, sodicity and toxicity problems in soils not only reduce crop productivity and quality, but also limit the choice of crops and reduce the selection of crops.

TL;DR: In this article, the water productivity of the lowland rice under aerobic conditions was higher or on a par with that of lowland variety under flooded conditions, reaching values of 0.6-0.8 ǫ−1 water.

TL;DR: In this article, an irrigation experiment with saline water at different concentrations was carried out over a 7-year period on the same clay-silty soil in the Volturno Valley at Vitulazio to evaluate long-term effects of irrigation with NaCl on crops and soil.

TL;DR: In this paper, the effect of two water management strategies i.e. alternate and mixed supply of fresh [canal water (0.55 ǫdS/m)] and saline [drainage water (4.2 ǔ s/m] water in six ratios applied through drip and furrow method on tomato yield and growth, and salt concentration in the root zone were investigated in the Nile Delta, Egypt.

TL;DR: In this article, a field experiment was conducted in an olive orchard of impoverished sandy soil to evaluate the efficacy of different management systems involving the use of plant covers, with respect to the tillage systems generally used in semiarid, continental environments.

TL;DR: In this paper, the effect of various levels of water and N application through drip irrigation on seed cotton yield and water use efficiency was evaluated in two methods of planting (normal sowing and paired sowing).

TL;DR: In this paper, the response of mature "Andross" cling peach (Punus persica L. Batch) trees to regulated deficit irrigation in deep soils was studied for three years.

TL;DR: In this paper, a field experiment was conducted to examine the yield promotion of potato crops cultivated with in plastic-covered ridges and supplied with water from a furrow rainfall harvesting (PRFRH) system.

TL;DR: Major differences in the negative slopes of the correlation lines indicate that decreases in plant water uptake, from 3.5 to 5% per dS m −1 , are cultivar-specific and cannot be generalised.
