“…This function depicted that as salinity level of irrigation water increased, the yield level of wheat decreased. This result is in full agreement with that of Data et al (1998). Water productivity for grain production under the treatments synchronized with grain yield of the corresponding treatments.…”

Response of wheat (Triticum aestivum L., cv. Shatabdi) to irrigation water of five salinity levels was investigated at the Bangladesh Agricultural University (BAU) farm with a view to search for a possible advantageous salinity level for the crop. The experiment comprised five treatments − I 1 : irrigation by fresh water of background salinity 0.385 dS m −1 (control) and I 2 − I 5 : irrigation by synthetic saline water (prepared by mixing sodium chloride salt with fresh water) of electrical conductivity (EC) 4, 7, 10 and 13 dS m −1 (at 25 o C), respectively. Wheat was grown under three irrigations applied at maximum tillering, booting and milking/grain filling stages, and with recommended fertilizer dose. Irrigation water of EC ≥10 dS m −1 significantly (p = 0.05) suppressed most growth and yield attributes, and yield of wheat compared to irrigation by fresh water (I 1 ). An attention-grabbing observation was that irrigation by saline water of 4 dS m −1 (I 2 ) contributed positively to the crop attributes. Leaf area index (LAI), spike length, spikelets and grains per spike, 1000-grain weight and above ground dry matter (ADM) of wheat increased by 1.9−3.4, 0.9, 2.6, 7.4, 2.1 and 2.8−6.0%, respectively in I 2 compared to the control. The improvement in the LAI and ADM in I 2 was significant over I 1 . Because of the largest spike density, the utmost grain (3.85 t ha −1 ), straw (5.09 t ha −1 ) and biomass (8.93 t ha −1 ) yields of wheat were however obtained under I 1 . The proposition of the advantageous irrigation water salinity level of 4 dS m −1 thus warrants further investigation.

“…Very few studies exist for crop response under saline conditions. In cases of poor water quality, the level of sodium content in water should be considered as a third factor because sodium content strongly affects crop production (Dinar et al, 1991;Datta et al, 1998;Beltrã o et al, 2002a).…”

This paper uses a dynamic model to explore the issue of irrigation-induced salinity, which puts irrigation at risk in most irrigated areas throughout the world. We address the design of instruments that an irrigation district board could implement to induce irrigators to take sustainable irrigation decisions. In our approach, the irrigators located above an aquifer participate in the accumulation of groundwater, a stock pollution. We analyse input-based instruments to induce the agents to follow the optimal stock path.
