Abstract Water conservation starts from rationalizing irrigation, as it is the largest consumer of this vital source. Following the critical and urgent nature of this issue, several works have been proposed. The idea of most researchers is to develop irrigation management systems to meet the water needs of plants with optimal use of this resource. In fact, irrigation water requirement is only the amount of water that must be applied to compensate the evapotranspiration loss. Penman-Monteith equation is the most common formula to evaluate reference evapotranspiration, but it requires many factors that cannot be available in many cases. This leads to… More >

Abstract This study adopted the method of barrel planting to artificially set the salt content of six different soils (CK:1.5 g kg^-1 , T1:3.0 g kg^-1 , T2:4.0 g kg^-1 , T3:5.3 g kg^-1 , T4:6.2 g kg^-1 , T5:7.3 g kg^-1 ) to study the effects of different degrees of mild salt stress on photosynthetic physiology, growth index and yield of cotton under drip irrigation. The results showed that with the increasing salt stress and the prolongation of stress time, the photosynthetic physiological indexes of cotton showed a downward trend (P < 0.01), and the plant height and leaf area… More >

Abstract Maize being sub-tropical crop is sensitive to water deficit during the early growth stages; particularly clay-rich soil, due to the compaction of the soil. It is well-documented that potential sub-surface drip irrigation (SDI) (Full irrigation; SDIFull (100% field capacity (FC)), Deficit irrigation; SDIDeficit (70% FC)) improves water use efficiency, which leads to increased crop productivity; since it has a constraint that SDI excludes soil air around the root-zone during irrigation events, which alter the root function and crop performance. Additionally, in clayrich soils, the root system of plants generally suffers the limitation of oxygen, particularly the temporal hypoxia, and occasionally… More >

Abstract The scarcity of water in arid and semiarid regions of the world is a problem that every day increases by climate change. The subsurface drip irrigation (SDI) and changes in population density of plants are alternatives that can be used to make a sustainable use of water. Therefore, the objectives of this study were to determine the combination that allows for an increased corn performance and efficient use of water without losing the quality of forage. Three different irrigation levels were applied through a system of a SDI at three different densities of forage maize plants in an arid region.… More >

Abstract We investigated the levels of F and its relationship with As, B and V in ground and surface waters of the southern Pampas, where cases of dental and skeletal fluorosis, and arsenic in hair and urine samples have been detected in the rural population. Eating vegetables and cereals grown in irrigated areas with excessive fluoride may increase the risk of fluorosis due to the addition of the extra F contributed from other sources such as drinking water. Moreover, if these elements exceed the tolerance of crops produce toxicity and, like salinity, they decrease the potential crop yield. Within an area… More >

Abstract The objective of this work was to evaluate, under irrigation and limited irrigation, the grain yield of 40 F7 sorghum lines (Sorghum bicolor L. Moench) selected by tolerance to drought in the Facultad de Agronomía at the Universidad Autónoma de Nuevo León (FAUANL) in Marín, Nuevo León, Mexico. Studies were conducted in College Station, Texas in the cycle Autumn-Winter 2011, and in Lubbock, Texas in the growing cycle Spring-Summer 2011. The 40 sorghum lines were divided into two groups of 20 genotypes each to integrate two experiments, and five more experimental lines and a commercial hybrid as a control. Thereafter,… More >

Abstract This research was performed at the agricultural experimental center of the Facultad de Agricultura y Zootecnia, Universidad de Durango, Mexico. The main objetive was to determine the best amount of cow manure application and its effect on corn production, quality and nutrient uptake. Two factors were studied in this experiment that started in 2000. The results presented in this paper correspond to 2001. The factors were (1) crop, with the levels corn alone and corn-soybean, and (2) cow manure (with the levels: 0, 40, 80, 120, 160 Mgr/ha) and chemical fertilizer (100-150-0 kg/ha of N, P₂O₅ and K, respectively). The… More >

Abstract A long-term study was conducted at different locations of Southwestern Buenos Aires to evaluate the effects of N fertilization at different growth stages of soybean on yield, plant nitrogen concentration and seed protein and oil concentrations. Yields were increased in six out of ten trials, and the response was highest with N fertilization at the beginning of grain development (R5). Different nitrogen sources were applied at seeding which gave higher yields and increased seed protein content than the non-fertilized, non-nodulated treatment. Urea was the most effective N source.

Abstract Fresh water is a valuable nonrenewable resource and plays an important role in maintaining economic and social development. Considering its large population and consumption potential, water resource deficits will certainly not allow a sustainable development of basic industries in China in the near future. Application of sewage irrigation, to some extent, was regarded as an alternative way to solve the problem of agricultural water shortage in some areas (such as North China). However, accompanied with an extensive implementation of sewage irrigation, some problems with sewage irrigation became gradually obvious in agriculture, especially those related with pollution and destruction of farmlands.… More >
