“…However, in order to assure maximum yields from crops irrigated with saline water, it is necessary to develop special management procedures (Pasternak and De Malach, 1994). Presently, drip irrigation is widely regarded as the most promising irrigation system to use saline water (Meiri and Plantz, 1985). Several factors contribute to the good results obtained with saline water irrigation using drip irrigation (Dasberg and Or, 1999): (i) less water use (high application efficiency) results in less salt deposited on the field, (ii) avoidance of leaf burn, (iii) high frequency drip irrigation prevents the soil from drying out between irrigation events, thereby avoiding peaks in salt concentration and concomitant high osmotic potentials and (iv) salts are continuously leached out from the wetted section and accumulate at the wetting front away from the active root zone.…”

The use of alkali ground water constitutes a major threat to irrigated agriculture in semiarid parts of India. The entire arid and semiarid region in India is characterized by low rainfall and has the problems either of water scarcity or poor quality ground water and it can be better utilized for irrigation through drip irrigation system. An experiment was conducted on tomato crop at Central Institute of Post Harvest Engineering and Technology (CIPHET) Abohar, Punjab to study the effect of blending fresh and saline irrigation water on yield and quality. The good quality canal water (EC of 0.38 dS/m) and ground water (EC 19.5 dS/m) were mixed in ratio of 100% Fresh (F), 75:25 (Fresh: saline; F:S) and 50:50 (F:S). The irrigation was done through drip system with three discharge rates (1.2, 2.4 and 4.2 lph) at three irrigation levels of 0.6, 0.8 and 1.0. The plant yield decreased significantly with increase in salinity levels of irrigation water (that is, increase in proportion of saline water). The maximum plant yield (3.55 kg/plant) was recorded with fresh water irrigation while 50% saline water blending in irrigation produced the lowest yield (2.64 kg/plant). The average yield decreased significantly when the discharge rate of emitters increased from 1.2 to 2.4 lph. The quality of tomato is observed inferior in saline water treatment compared to fresh water treatment. The TSS and acidity of tomato fruits increased with increase in the saline water ratios of irrigation water. As compared to 100% fresh water treatment, the mixing of 75% fresh and 25% saline water reduced tomato yield by 11% and gave a better quality tomato fruits at the discharge rate 2.4 lph and irrigation level 0.8. Hence, saline water can be utilized through drip system for sustainable yield and quality tomato production in water scarce area having poor quality ground water.

“…Plant response to salt stress can differ greatly depending on environmental factors in the soil. One of these factors is the distribution of salts in the root environment (Meiri and Plaut, 1985; Sonneveld and de Kreij, 1999). Soil salinity is often heterogeneous in saline fields, and thus it has attracted a number of studies on plant response to non-uniform salinity in the root zone (Meiri and Plaut, 1985; Dong et al , 2008, 2010; Bazihizina et al , 2009).…”

A new split-root system was established through grafting to study cotton response to non-uniform salinity. Each root half was treated with either uniform (100/100 mM) or non-uniform NaCl concentrations (0/200 and 50/150 mM). In contrast to uniform control, non-uniform salinity treatment improved plant growth and water use, with more water absorbed from the non- and low salinity side. Non-uniform treatments decreased Na+ concentrations in leaves. The [Na+] in the ‘0’ side roots of the 0/200 treatment was significantly higher than that in either side of the 0/0 control, but greatly decreased when the ‘0’ side phloem was girdled, suggesting that the increased [Na+] in the ‘0’ side roots was possibly due to transportation of foliar Na+ to roots through phloem. Plants under non-uniform salinity extruded more Na+ from the root than those under uniform salinity. Root Na+ efflux in the low salinity side was greatly enhanced by the higher salinity side. NaCl-induced Na+ efflux and H+ influx were inhibited by amiloride and sodium orthovanadate, suggesting that root Na+ extrusion was probably due to active Na+/H+ antiport across the plasma membrane. Improved plant growth under non-uniform salinity was thus attributed to increased water use, reduced leaf Na+ concentration, transport of excessive foliar Na+ to the low salinity side, and enhanced Na+ efflux from the low salinity root.

“…In arid and semi-arid regions salinity is a major constraint on the growth of crops, and there has been considerable research on both the physiology of crop response to salinity (Munns, 1993) and on the management of crops grown on saline soils (Meiri & Plaut, 1985) . Selection of salt-tolerant crop species and breeding for greater salt-tolerance has been pursued in an attempt to increase productivity under saline conditions (Epstein, 1985 ;Saxena et al .…”

Salt-tolerance in potato (Solanum tuberosum L .) was selected on the basis of germination and survival of seed sown in trays of perlite suspended in either 75 or 150 mM NaCl . Salinity reduced the germination of seed . Genetic differences in salt-tolerance were apparent with salt reducing germination more in seed collected from cv . Cara than in that collected from cv. Maris Piper. Progeny from the seedling selection were then grown to maturity to produce tubers .The relative tolerance of the parental cultivars and of unselected and selected progeny to long-term exposure to salinity was examined in a pot experiment in which plants were irrigated with either fresh water or 50 mM NaCl solution from one week after plant emergence . In this experiment, salinity significantly reduced leaf conductance, total dry matter production and partitioning of assimilate to tubers . Salinity reduced dry matter production and assimilate partitioning to tubers to a greater extent in Cara than in M . Piper. Progeny selected for short-term salttolerance did not exhibit greater long-term salt-tolerance than unselected progeny, and both were more sensitive than M . Piper.These results demonstrate genetic variation in salt-tolerance in potato . However, although there was a correlation between the performance of the parent to long-term salinity and survival of progeny in the seedling selection, there was no correlation between short-and long-term salt-tolerance . This suggests that characters underlying short-term tolerance may contribute to long-term tolerance but do not of themselves confer long-term tolerance . Future progress in selecting for improved salt-tolerance depends on understanding the effects of salinity on the physiological processes underlying growth and carbon partitioning .
