“…With wheat, Mojid and Hossain [14] and Mojid et al [12] stated that saline water irrigation could be applied at later growth stages when plants have better salinity tolerance. On the other hand, the cotton yield contributing attributes and yield was significantly higher when fresh water was used to irrigate and significantly decreased with increasing the levels of salinity from 4-12 dS m −1 [44]. In this study, irrigation levels also significantly (p < 0.001) depressed the yield components of sunflower-like seed weight head −1 , as well as sunflower seed yield, if a single application of LSW was followed by two applications with MSW (Tables 3 and 4).…”

The intensification of cropping systems in the salt-affected coastal zones of the Ganges Delta can boost food security in the region. The scarcity of fresh water, coupled with varying degrees of soil and water salinity are however limiting factors for the expansion of irrigated cropping in that area. In this study, we assessed the potential of growing sunflowers using combinations of low and medium saline water for irrigation. The experiments were conducted at two locations with six irrigation treatments in 2016–2017 and 2017–2018. The treatments were: T1—two irrigations at early vegetative (25–30 days after sowing; DAS) and flowering stages (60–65 DAS) with low salinity water (LSW, electric conductivity, ECw < 2 dS m−1); T2—two irrigations, one at the vegetative stage with LSW and one at the flowering stage with medium salinity water (MSW, 2 < ECw < 5dS m−1); T3—two irrigations, one at the vegetative stage with LSW and one at seed development stage (75–80 DAS) with MSW; T4—three irrigations at the vegetative, flowering and seed development stages with LSW; T5—three irrigations, at vegetative stage with LSW, and flowering and seed development stages with MSW; and T6—three irrigations, two at the vegetative and flowering stages with LSW and one at the seed development stage with MSW. Irrigation with LSW at early growth stages and MSW at later growth stages did not significantly (p < 0.05) affect the yield compared to the LSW irrigation at early and later growth stages. Crop water productivity and irrigation water productivity of sunflowers (p < 0.001) increased substantially with the decreasing amount of irrigation water with an average of 1.18 kg m−3 and 2.22 kg m−3 in 2017 and 0.92 kg m−3 and 1.29 kg m−3 in 2018, respectively. Grain yield was significantly correlated with root zone solute potential. The flowering and seed development stages of sunflowers in February–March were sensitive to both low and medium saline water irrigation for seed yield. Overall, the results show that irrigation with LSW (ECw < 2dS m−1) at early growth stages and MSW (2 < ECw < 5dS m−1) at later growth stages could be an option for dry-season sunflowers in the coastal zones of the Ganges Delta which would allow double cropping in this area.

“…Li et al (2019) opined that under fresh water shortage conditions, application of non-saline water at the seedling and flowering stage while saline-water application at fruit set-stage was the most suitable mode of irrigation for high yield production of tomato without deteriorating the soil properties. Gandahi et al (2017) concluded from a pot experiment that cotton gave the economical yield if six irrigations were provided with saline water and six irrigations with non-saline water in a conjunctive manner. Similarly, Chen et al (2018) suggested that the optimal mixing of nonsaline and saline water may be more beneficial for cotton production and avoid secondary salinization when using saline water.…”

A pot study was conducted to develop reasonable irrigation scheduling methods for rice-wheat crop rotation by conjunctive use of low-quality brackish water and good quality canal water. Treatments tested were; T1 (canal water), T2 (brackish water), T3 (brackish water for rice and canal water for wheat), T4 (last two irrigations to rice, and initial two irrigations to wheat with canal water), T5 (last two irrigations to rice but two initial and one last irrigation to wheat with canal water). Results revealed that irrigation with canal water resulted in the maximum mean biomass and grain yield of rice and wheat crops followed by cyclic use of brackish and canal water. While continuous irrigation with brackish water resulted the lowest mean biomass and grain yield. The different modes of irrigations also influenced chemical properties of soil, brackish water adversely affected the soil properties, and maximum pH of soil saturated paste (pHs), electrical conductivity of soil extract (ECe) and sodium adsorption ratio (SAR) were recorded where brackish water was used continuously. Therefore, it was concluded that when water is valuable and freshwater resources are limited, cyclic use of the canal and brackish water is also profitable with marginal effect on biomass and grain yield and proves least detrimental for soil health.
