ABSTRACT: Soil and water salinities are major environmental factors limiting the productivity of agricultural lands especially in arid and semi arid regions. To determine salinity threshold values and slope of the yield decrements for crops of wheat, barley and maize, SWAP model was study for an arid region located in Semnan Province (52◦25' N 35◦11' E), central part of Iran with area of 35000 ha including 94 villages belonged to irrigation network of Garmsar district. The data collected from the above 94 villages for years 1998 to 2007 were used to calibrate and simulate yield of wheat, barley and maize using the SWAP model. The irrigation water salinities of 2, 4, 6 and 8 dS m-1 were used and yield reductions versus soil saturation extracts were evaluated and salinity threshold values and slope of the yield reductions were determined for each of the above crops. The results showed that the SWAP model predict crop yields with good accuracy and the threshold values and slope of the yield reductions are site dependent. These values should be determined for each area in order to be able to plan better irrigation scheduling for arid regions which have soil and irrigation water salinities problems.

Underground irrigation water, particularly saline, when in arid and semi-arid regions of India may contain toxic amounts of B, from a trace up to 10 mg B/l (Anon. 1981–82). Continuous use of such water for irrigation may lead to the accumulation of salts and B in soil and this creates toxicity problems. Kanwar & Mehta (1970) have reported that water containing 2 mg B/l is hazardous if used on heavy soils. For sandy loam soils of semi-arid tracts in India, Chauhan & Powar (1978) have reported reductions in the grain yield of wheat and pea at 4 and 6 mg B/l respectively, while under similar conditions grain yield of lentil and barley was reduced at 3 and 6 mg B/l respectively (Chauhan & Asthana, 1981). So far, few attempts have been made to evaluate the effect of boronated saline water on soil and crops, under different agroclimatic conditions. A study of the effect of boronated saline water on an important oil-seed crop, linseed, on alkaline sandy loam soil in the semi-arid region of Agra, India was therefore undertaken.

Abstract The application of hydrogel in agriculture has gained a wide interest in the last decades due to the great benefits that it has provided to this sector. In Algeria, agriculture suffers from two main issues: water shortage and climate change, especially in the south of the country (Sahara), which is classified within the arid and semi-arid regions, where irrigation is based exclusively on groundwater. This paper presents an experiment of hydrogel application in agricultural soil for reducing overexploitation of groundwater used for irrigation. Hydrogels are super absorbent polymers. They are biodegradable and have the ability to absorb and retain a large amount of water. The aim of this work is to evaluate the effect of hydrogel on the efficiency of soil moisture retention through treating sandy soil with different doses of hydrogel. The results indicate that the application of hydrogel can increase the water retaining capacity of sandy soil up to 40%.

This study aimed to assess the spatiotemporal sensitivity of the net irrigation water requirement (NIWR) to changes in climate, for sixteen crops widely cultivated in four irrigation projects located in arid and semi-arid regions of Iraq. Using LARS-WG and five GCMs, the minimum and maximum temperature and precipitation were projected for three periods from 2021–2080 with 20-year steps (P1, P2, and P3) under representative concentration pathways (RCPs) 2.6, 4.5, and 8.5. Weather data available for a reference period from 1990–2019 in four representatives’ meteorological stations were used. The climate variables and other required data were inserted into the CROPWAT 8 NIWR tool. Findings revealed that the increase in the NIWR for the considered crops due to climate change falls in the range 0.1–42.4%, 1.8–44.5%, 1.2–25.1%, and 0.7–14.7% for the North Jazeera Irrigation Project (NJIP), Kirkuk Irrigation Project (KRIP), Upper Khalis Irrigation Project (UKIP), and Dalmaj Irri-gation Project (DLIP), respectively. Barley is more susceptible to changes in climate, whereas maize, potato, soybean, and millet are found to withstand changes in climate better than others. The novel outcomes of this study support optimal spatiotemporal allocation of irrigation water requirement and the sustainable management of water resources in a changing climate in arid and semi-arid regions.

Tetragonia Tetragonioides

The main purpose of this experiment was to study the effect of several irrigation water regimes on Tetragonia tetragonioides (Pall) O. Kuntze in semi-arid regions. During the experiment period, it was measured that several irrigation regimes were affected in terms of growth, biomass production, total yield, mineral composition, and photosynthetic pigments. The experiment was conducted in the greenhouse at the University of Algarve (Portugal). The study lasted from February to April in 2010. Three irrigation treatments were based on replenishing the 0.25-m-deep pots to field capacity when the soil water level was dropped to 70% (T1, wet treatment), 50% (T2, medium treatment), and 30% (T3, dry treatment) of the available water capacity. The obtained results showed that the leaf mineral compositions of chloride and sodium, the main responsible ions for soil salinization and alkalization in arid and semi-arid regions, enhanced with the decrease in soil water content. However, the minimum amounts of chlorophyll, carotenoids, and soluble carbohydrates in the leaf content were obtained in the medium and driest treatments. On the other hand, growth differences among the several irrigation regimes were very low, and the crop yield increased in the dry treatment compared to the medium treatment; thus, the high capacity of salt-removing species suggested an advantage of its cultivation under dry conditions.

The high salt concentrations found in irrigation formation of water in semi-arid regions lead to changes on crops growth and development and can lead to halomorphicsoils formation. In this context, it was proposed to evaluate the morphophysiology and production of colored herbaceous cotton BRS Topaz fertilized with nitrogen under a saline-sodic soil and submitted to the irrigation with water of different salinities. The experiment was conducted in an eutrophic sandy quartzarênico Neossol in the municipality of Campina Grande, Paraíba, Brazil, adopting a completely randomized design in 5x5 factorial with three repetitions, with five salinity levels of the the irrigation water (0 7; 2.7; 4.7; 6.7 and 8.7 dS m-1 at 25°C) and five levels of nitrogen (40; 60; 80; 100 and 120 mg of N kg-1). Regarding cotton growth, no effect was observed for the interaction between salinity and soil nitrogen doses. The absolute growth rate for height, stem diameter and leaf area decreased with an increase in the irrigation water electrical conductivity, being leaf area the most affected variable.The number of bolls and the cotton seed production per plant decreased with the salinity increase and increased with in increase of nitrogen fertilization.
