“…Different remedial approaches are available to mitigate the drought and salinity stresses in paddy fields. These generally include cultivation of salinity and drought-tolerant rice genotypes, using rice growth-regulators, applying plant growth-promoting microorganisms associated with rice roots (Etesami, 2019), removing deposited salt, and adjusting fertilizer management (Djaman et al, 2020). Among these approaches, the use of microorganisms that associate with rice plant roots has been shown to improve rice productivity via inducing rhizosphere fertility (Etesami, 2019), ultimately increasing rice yield.…”

“…Early spring preplant irrigation was more effective compared to the fall off season irrigation [4]. For sustainable crop production under salt-affected soils, salt in the soil profile is managed and leached out using off season precipitation and preplant irrigation with good quality water during fallow periods [23][24][25][26]. Ayars reported the successful salt management by preplant irrigation in the San Joaquin Valley of California and other regions across the world [24].…”

Soil moisture content early growing season is determinant for crop season planning mainly a decision on planting date. In the region where off season or early season precipitation does not much the conditions for seed germination and plant growth/ development, preplant irrigation is applied to meet these conditions. Also, under limited water availability or low system capacity to meet crop water requirement at peak evapotranspiration, preplant irrigation could be applied to store water within the crop root zone. However, its efficiency or effectiveness depends on the soil type and soil water storage efficiency. This review explored the advantages and disadvantages of the practice and its impact on crop yield and water productivity using summaries of different researches conducted mostly in the United States and other regions. The consideration of applying preplant irrigation should be examined regarding soil type, crop management practices, tillage and residue management, irrigation technique, actual precipitation pattern and forecast, crop choice to optimize the preplant irrigation practice for system sustainability.

“…Grains yield characteristics like panicle length, panicle numbers, 1000grain weight and grain quantity are all negatively affected by soil salt levels beyond the critical threshold (3.0 dSm − 1 ) (Mumtaz et al 2017). Moreover, rice grain yield was reported to be reduced by 50% under the electrical conductivity (EC) of 6.0 dSm − 1 (Djaman et al 2020).…”

Purpose: Over the past two decades, rice production has been seriously threatened by the progressively diminishing agricultural land caused by both environmental and anthropogenic issues. To support the policy decisions for food security in Bangladesh, we must use marginal soil, such as salt-affected soil and suitable variety for a particular region for higher yield. Methods: A field experiment was conducted in saline soil (8.7 dS m-1) in Khulna, Bangladesh during December 2020 to April 2021 to identify the best rice cultivar following Randomized Complete Block design with three replications. Six rice varieties (BRRI dhan47, BRRI dhan28, BRRI dhan67, Black rice, Violet rice and Heera hybrid) were tested in this experiment to observe their growth and yield performance as well as macro nutrient uptake. Results: In this study, Black rice died at 74 days after transplanting due to the excess salt stress. The findings revealed that Heera hybrid rice produced significantly (p ≤ 0.05) higher tiller hill-1, panicle hill-1, panicle length, biological yield, harvest index, grain yield, straw yield, total grain panicle-1 and filled grain compared to other varieties except BRRI dhan67. On the other hand, significantly highest number of leaf hill-1, 1000-grain weight, P, S and Na uptake was obtained from BRRI dhan67. Additionally, maximum grain N and K uptake was observed for Heera hybrid rice as compared with other cultivars. Conclusions: It can be summarized that Heera hybrid and BRRI dhan67 could be effective to improve rice production and nutrient uptake in coastal saline soil of Bangladesh followed by BRRI dhan47, BRRI dhan28 and Violet rice.
