“…Additionally, the low salinity in 2012/2013 is most likely affected by the lack of significance of salt stress in this year. Similar results were reported by (Sharma et al, 1994(Sharma et al, , 2001Chauhan et al, 2008;Verma et al, 2012), these authors reported that in the regions with a monsoon climate (with an average annual rainfall exceeding 500 mm), more than 80% of the salts accumulated during winter wheat cultivation are leached without any long-term increase in the soil salinity.…”

“…The threshold value is the maximum average salt concentration in the root zone at which crop yield is not significantly reduced. Soil resource health and crop yield are two variables of great interest when using saline water for crop production (Verma et al, 2012). Therefore, the effects of saline water on crop production and soil salinity should be studied simultaneously.…”

Crop models assist in generating crop productivity trends under future climate and different irrigation water supply scenarios. In this study, the AquaCrop model with a salinity module to simulate the grain yield and water productivity of four wheat varieties, including three salt-tolerant (i. ) for grain yield, were 0.85, 0.96, 0.94 and for biomass 0.7, 0.95, 0.95, respectively, for all varieties and salinity levels. It was observed that the AquaCrop model was better at predicting the grain yield compared to biomass and water productivity for all varieties and salinity levels.

“…Meanwhile, the quality of irrigation water is also becoming low. As a result, saline water irrigation and lower qualitywater, such as saline groundwater have been used more readily in agriculture to overwhelmed drought and sustain crop production (Verma et al, 2012;Li et al, 2015). Reuse of diluted saline water for irrigation of plants becomes the readily available water when water resources are scare.…”

Salinity is one of major environmental problem which is limiting the agricultural production. This research was conducted to evaluate the effect of re-watering on Brassica napus L., and determination of an appropriate regime for dilution of salted water by studying photosynthetic and growth response of B. napus to salt stress and subsequent re-watering. Plants were treated with NaCl (Nc 1 : 2.5, Nc 2 : 5, Nc 3 : 10; g L -1 ); Na 2 SO 4 (Ns 1 : 2.5, Ns 2 : 5, Ns 3 : 10; g L -1 ) and mixed salts treatments (M 1 : Nc 1 + Ns 3 ; M 2 : Nc 3 + Ns 1 ; M 3 : Nc 2 + Ns 2 ; g L -1 ) and 0 as control, followed by re-watering. In salt stress phase, maximum reduction in net photosynthetic rate (P N ) was noted 79.54%, 80.72%, 84.54%, and 74.84% for Nc 3 , Ns 3 , M 1 and M 2 , respectively, under high concentration levels. To maintain P N , carbonic anhydrase (CA) activity was stimulated and kept water status stable under low (Nc 1 and Ns 1 ) to medium concentration levels (Nc 2 , Ns 2 and M 3 ), and the decreases in P N under Nc 2 , Ns 2 and M 3 were 48.28%, 55.58% and 58.69%, respectively. However, during rewatering phase, growth and physiological parameters were recovered well due to regulation of CA activity under low to medium concentration levels. Relatively as compare to other stress levels more recovery in P N was found after rewatering under medium concentration levels, which were 44.94%, 53.45% and 63.04%, respectively. Though aimed at consideration of high production in B. napus, the best re-watering time was found to be when plants undergo medium concentration levels. Therefore, this study provides a new method for dilution of saline irrigation based on plant physiology.
