“…With the increasing problems of disposal of saline drainage water and expanding demands on high-quality water for other purposes, on-farm management of saline drainage water for crop production has gained recognition (Rhoades et al, 1989;Sharma et al, 1989Sharma et al, , 1991. Various strategies have been proposed to use drainage water for irrigation (Rhoades, 1984(Rhoades, , 1987Boumans et al, 1988;Sharma et al, 1993Sharma et al, , 1994Sharma and Rao, 1998;Tyagi and Tyagi, 1990).…”

The irrigated arid and semi-arid zones in India face twin problems of overall water scarcity and waterlogging accompanied by salinity. Subsurface drainage has proved successful in the rehabilitation and conservation of waterlogged saline soils. Drainage water from subsurface drainage systems seems to be an important source of water in the next millennium to tide us over the anticipated water scarcity problem in agriculture. However, the drainage waters from subsurface drainage systems are often saline and in the absence of a natural outlet, their disposal creates a problem. Various possible options have been discussed to mitigate the environmental threat posed by low quality drainage waters. Issues relating to potential reuse of low quality drainage waters along with management practices are addressed. Effects of factors influencing the long-term sustainable use of saline drainage waters are presented and it is emphasized that special management practices have to be followed/evolved for sitespecific water quality, soil, crop and climatic conditions. However, the extent of salt leaching and crop establishment will depend on the total amount of monsoon rains and adequate subsurface drainage. It has been concluded that the use of a part of the saline drainage water in the post-reclamation phase will not only augment the water supply but also minimize effluent disposal requirements.

“…But the disposal of poor quality drainage water poses a serious environmental problem (Sharma et al, 1993). The conjunctive use of drainage effluent allows the development of irrigated agriculture and also solves its disposal problem (Rhoades, 1987;Westcot, 1988;Sharma et al, 1991). The adoption of salt tolerant crops is suggested, while utilizing the poor quality groundwater, as it reduces the harmful effects of salts on plant growth .…”

“…For explaining this further, it is important to mention here that irrigation waters with EC-6, 9 and 12 dS/m were formed by mixing treatment-specific fixed proportions of canal (CW) and drainage waters (DW) in the experimental area. Natural electrical conductivities of especially drainage (DW) waters varied considerably (18-27 dS/m) over seasons (Sharma et al, 1991) thereby resulting into applied irrigation waters with lower electrical conductivities than actually designed 6-, 9-and 12-dS/m concentrations, during the experimental period. Irrigation treatments associated with mixing of larger proportions of drainage waters were, in general, associated with larger differences between the actual and design electrical conductivities.…”

Conjunctive use of saline/non-saline irrigation waters is generally aimed at minimizing yield losses and enhancing flexibility of cropping, without much alteration in farming operations. Recommendation of location-specific suitable conjunctive water use plans requires assessment of their long-term impacts on soil salinization/sodification and crop yield reductions. This is conventionally achieved through long-term field experiments. However such impact evaluations are site specific, expensive and time consuming. Appropriate decision support systems (DSS) can be time-efficient and cost-effective means for such long-term impact evaluations. This study demonstrates the application of one such (indigenously developed) DSS for recommending best conjunctive water use plans for a, rice-wheat growing, salt affected farmer's field in Gurgaon district of Haryana (India). Before application, the DSS was extensively validated on several farmers and controlled experimental fields in Gurgaon and Karnal districts of Haryana (India). Validation of DSS showed its potential to give realistic estimates of root zone soil salinity (with R = 0.76-0.94; AMRE = 0.03-0.06; RMSPD = 0.51-0.90); sodicity (with R = 0.99; AMRE = 0.02; RMSPD = 0.84) and relative crop yield reductions (AMRE = 0.24), under existing (local) resource management practices. Long term (10 years) root zone salt build ups and associated rice/wheat crop yield reductions, in a salt affected farmer's field, under varied conjunctive water use scenarios were evaluated with the validated DSS. It was observed that long-term applications of canal (CW) and tube well (TW) waters in a cycle and in 1:1 mixed mode, during Kharif season, predicted higher average root zone salt reductions (2-9%) and lower rice crop yield reductions (4-5%) than the existing practice of 3-CW, 3-TW, 3-CW. Besides this, long-term application of 75% CW mixed with 25% TW, during Rabi season, predicted about 17% lower average root-zone salt reductions than the cyclic applications of (1-CW, 1-TW, 2-CW) and (2-CW, 1-TW, 1-CW, i.e., existing irrigation strategy). However, average wheat crop yield reductions (16-17%) simulated under all these strategies were almost at par. In general, cyclic-conjunctive water use strategies emerged as better options than the blending modes. These results were in complete confirmation with actual long-term conjunctive water use experiments on similar soils. It was thus observed that such pre-validated tools could be efficient means for designing, local resource and target crop yield-specific, appropriate conjunctive water use plans for irrigated agricultural lands.
