“…Therefore, selection of the proper conjunctive use mode is required for salinity management at the root zone. Wheat yields reported by Naresh et al (1993) and Sharma et al (1994) have also been given in Table III to discuss the validity of the preference order. In the case of wheat crops, the highest yield of 5.45 t ha À1 was reported (Naresh et al, 1993), where all irrigations were given by canal water.…”

Use of saline groundwaters is inevitable in rice-wheat, cotton-wheat, and millet-wheat crop rotations in the northern region of India due to limited canal water supplies. The UNSATCHEM model is calibrated and validated with field data on saline water use for the wheat and cotton crop. The calibrated and validated model has been employed to study different aspects of the salinisation process. The effect of irrigation water quality on the salinisation process is understood with the help of simulations in which irrigation waters of different SAR, SO 4 2Àand Cl À concentrations are used. A linear relation is observed between the weighted average of irrigation water salinity and the root zone. The salinisation process under different conjunctive use practices is understood through simulations. The practices are compared on the basis of temporal changes in root zone salinity with reference to the sensitivity of the wheat crop to salinity for deciding the preference of one conjunctive use practice over another. The preference order, thus prepared, is verified with the published yield data of wheat from conjunctive use field studies. The effect of soil texture on salinisation is studied through simulations. The saturated water content influences the salinisation process more than the hydraulic conductivity. The long-term simulations as per water quality guidelines for a six-year period under wheat-cotton rotation are carried out to assess the sustainability of saline water use for crop production.

Le modèle UNSATCHEM a été calibré et validé en utilisant des données de terrain recueillies sur l'utilisation des eaux salées pour la culture du blé et du coton. Ainsi calé, il a été utilisé pour étudier les différents aspects du processus de salinisation. L'effet de la qualité de l'eau d'irrigation sur le processus de salinisation a été analysé avec l'aide des simulations dans lesquelles sont utilisées des eaux d'irrigation de concentrations différentes de SAR, SO 4 2À et C1 À . Une relation linéaire a été obtenue entre la salinité moyenne de l'eau d'irrigation calculée et la zone racinienne. Le processus de salinisation dans différentes pratiques d'utilisation conjointe eau de surface (douce)/eau souterraine (salée) a été analysé par le biais de simulations. Les pratiques sont comparées sur la base de changements temporels dans la salinité de la zone racinienne, en particulier pour ce qui concerne la sensibilité du blé à la salinité, dans le but de classer les utilisations conjointes par rapport à d'autres pratiques. L'ordre de préférence ainsi établi a été vérifié avec les données de rendement publiées sur le blé à partir des études d...

“…This strategy may work better in arid climates with very low rainfall but it is of natural occurrence under the monsoon climate. Experiments by Sharma et al (1994), where combined use of saline drainage water (EC ¼ 10.5-15.0 dS m À1 ) and canal water (EC ¼ 0.5 dS m…”

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.

“…Sharma et al [7] mentioned that cyclic irrigations with canal and drainage water at different sequences resulted in wheat yields of 88% to 94% of the potential, at the same time it did not cause any significant reduction in pearl-millet and sorghum yields. Also Sharma et al [8] reported a sunflower yield of 82% of the potential using the same manner of irrigation technique.…”

Background:A pot experiment was conducted to determine the effects of alternate irrigation with saline (S) and fresh (F) water on growth, nitrogen uptake and nitrogen use efficiency in Sorghum crop (Sorghum bicolor L.) manured with Elaeagnus angustifolia leaves (GM) using 15 N. Method:Five types of irrigation systems abbreviated as (F, 2F:1S, 1F:1S, 1F:2S and S) and one rate of Green Manure (GM) were employed. Result:Results showed reductions in both Dry Matter yield (DM) and nitrogen uptake (NY) in sorghum grown under different types of irrigation systems as compared with the control (F). The reduction rates of these two parameters increased with increasing number of irrigations with saline water. However, E. angustifolia leaves applied as green manure mitigated the harmful effect of salinity on plant growth parameters. The percent increments as a result of GM application were 9, 19, 43, 43 and 65% for DM, and 33, 30, 42, 36 and 60% for NY in F, 2F:1S, 1F:1S, 1F:2S and S, respectively. Nitrogen use efficiency of added green manure ranged between 25 and 47% in the different types of irrigation systems. Our results indicated that increment of NY in green manured sorghum plants was mainly attributed to its nitrogen availability. According to the availability of S and F water resources, and the economic returns aimed by farmers in the semi-arid regions, it is recommended to use (2F:1S, 1F:1S and 1F:2S) in combination with E. angustifolia leaf GM. Such a procedure can be considered as a promising agricultural practice to improve yield with a proper water resource investment.
