“…Germination of cotton seed and emergence of seedlings are generally delayed and reduced by salinity (Ashour and Abd ElHamid, 1970;Latif and Khan, 1976;AbulNaas and Omran, 1974;Soliman et al, 1980;Nazir et al, 1983;Younis et al, 1987;More and Malewar, 1988;Hamdy et al, 1993;Varghese et al, 1995;Qadir and Shams, 1997). However, there are varietal differences in response to salinity as, for example, cvs.…”

“…Electrical conductivity is a measure of the risk of salinity, the excess of it reduces the osmotic activity and interferes with the uptake of water and nutrients from the soil to the plant, so while the higher the EC less water will be available to plants (Nagaraju et al 2006;Joshi et al 2009, Ishaku et al, 2011, Obiefuna and Sheriff, 2011Nag and Ghosh, 2013). EC values under 250 µmhos/cm at 25 °C in the irrigation water are considered excellent (C1) of 250-750 are classified as good (C2) of 750-2000 (C3) are admissible in 2000 3000 (C4) is considered to be doubtful use, so the water above 3000 µmhos/cm at 25 °C values (C5) are considered inadequate, since soil salinity tends to increase in proportion to the concentration of salts in the water that is irrigated (Hamdy et al, 1993, Sharma andRao 1998;PerezSirvent et al, 2003), the concentration of salts in the soil can be two to six times corresponding to conductivity of irrigation water (Hamdy et al, 1993;PerezSirvent et al, 2003).…”

Quality indices of groundwater for agricultural use in the Soconusco, Chiapas, Mexico

et al. 2017

In Soconusco, Chiapas, in spite of the high availability of surface water, it is resorting to the use of groundwater. Knowledge about the quality of surface or groundwater used to irrigate crops in that region is low. This paper aims to contribute to the knowledge of the quality of groundwater for agricultural use through the characterization of the spatial variability. Assuming a random spatial distribution of 45 samples which were collected in situ were determined: acidity and alkalinity (pH), electrical conductivity (EC), Total Dissolved Solids (TDS), cations and anions and trace elements; in addition to the agricultural index: Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Soluble Sodium Percentage (SSP), Sodium Percentage (% Na), Kelly Ratio (KR), Magnesium Adsorption Ratio (MAR), Permeability Index (PI), Effective Salinity (ES), Salinity Potential (SP) and Osmotic Potential (OP). In general, SSP, % Na, KR, PI are low, there is only one anomalous point (9) with high values at W of the study area. Similarly, PS, ES, Cl, Na and SAR are low except point 16 and conversely, RSC and pH are high, except at this point located in the center of the study area. The results allow us to infer that the water in that aquifer presents no problems or sodicity toxic ions. In 27 sites sampled values above 250 µmhos/cm were found at 25°C, classified as medium to high risk of salinity, unsuitable for agricultural use. Analysis of the combined effect of the presence of sodium (SAR) and salinity (EC or TDS) shows that 27 of analyzing sites have restricted water medium at very high for use in irrigation.

“…Crops that are relatively salt sensitive can be irrigated with saline water during the less sensitive stages of growth (Rhoades, 1984). Specifically, fresh water should be used in early stages and saline water in later stages (Hamdy et al, 1993).…”

An experiment was undertaken at the McGill University experiment station at Ste-Anne de Bellevue, Canada, to study the effect of different fertilizers on green pepper yield as it is influenced by saline water supplied through a subirrigation system, which was used to supplement water stored in the soil. Green peppers (Capsicum annuum L.), cv. Bellboy, were grown in field lysimeters filled with a sandy loam soil. The lysimeters were covered with plastic sheets to prevent rainfall/surface water entry. Water having salinities of 1, 3, 5, and 7.5 dSиm Ϫ1 , was applied through the bottoms of the lysimeters, and steady-state water tables were maintained at 0.45 or 0.9 m from the surface. The soil solution salinity in the soil profile remained less than 3.5 dSиm Ϫ1 during the growing season, and there was no appreciable increase in soil solution salinity in the root zone. Five rates of fertilizers were applied on the soil R. M. Patel is Research Associate, S. O. Prasher
