Soil salinity and sodicity are among the main problems for optimum crop production in areas where rainfall is not enough for leaching of salts out of the rooting zone. Application of organic and Ca-based amendments have the potential to increase crop yield and productivity under saline–alkaline soil environments. Based on this hypothesis, the present study was conducted to evaluate the potential of compost, Ca-based fertilizer industry waste (Ca-FW), and Ca-fortified compost (Ca-FC) to increase growth and yield of maize under saline–sodic soil conditions. Saline–sodic soil conditions with electrical conductivity (EC) levels (1.6, 5, and 10 dS m−1) and sodium adsorption ratio (SAR) = 15, were developed by spiking soil with a solution containing NaCl, Na2SO4, MgSO4, and CaCl2. Results showed that soil salinity and sodicity significantly reduced plant growth, yield, physiological, and nutrient uptake parameters. However, the application of Ca-FC caused a remarkable increase in the studied parameters of maize at EC levels of 1.6, 5, and 10 dS m−1 as compared to the control. In addition, Ca-FC caused the maximum decrease in Na+/K+ ratio in shoot up to 85.1%, 71.79%, and 70.37% at EC levels of 1.6, 5, and 10 dS m−1, respectively as compared to the control treatment. Moreover, nutrient uptake (NPK) was also significantly increased with the application of Ca-FC under normal as well as saline–sodic soil conditions. It is thus inferred that the application of Ca-FC could be an effective amendment to enhance growth, yield, physiology, and nutrient uptake in maize under saline–sodic soil conditions constituting the novelty of this work.

<p>Saline-sodic soil is considered as a serious problem which could negatively affect rice water use efficiency, plant growth, and yield. Therefore, the objective of the current study was to investigate the effects of gypsum applied before sowing (i.e. gypsum and without gypsum) and irrigation interval treatments applied after anthesis (irrigation every 4, 6, 8 days) on chemical characterizations of clay saline-sodic soil. In addition, the effect of these treatments on rice growth, water use efficiency and related parameters and yield were investigated. A significant higher efficiency in reclamation of clay saline-sodic soil was obtained in terms of reducing SAR, Na<sup>+</sup> and EC when gypsum was applied and water was added every four or six days intervals in comparison to non-treated soil with gypsum and water added every eight days interval. The highest number of spikelets per panicle, ripened grains percent, grain and straw yields were obtained when rice plants were grown on soil treated with gypsum and irrigated every four and/or six days intervals compared to soil with no gypsum and irrigated every eight days interval. The highest water use efficiency was obtained from rice irrigated every six days interval. In conclusion, it may reduce the hazards of the saline-sodic soil due to application of gypsum which improved soil properties, rice growth and its productivity when plants were irrigated every four or six days intervals. This might be due to the valuable nutrient source of gypsum interns of Ca, which mitigated the toxicity caused by salts in saline soils. Gypsum can also be considered as an effective application for clay saline-sodic soil in the North Delta, Egypt.</p>

The experiment was carried out with rice (BRRI dhan48) grown in saline soil at the premises of the Department of Soil, Water and Environment, University of Dhaka to evaluate the impacts of agricultural amendments, such as rice hull (RH), rice straw (RS) and sawdust (SD) each applied at the rates of 0, 4 and 8 t ha-1 in moist (80% moisture) and saturated soil conditions. Most of the growth and yield components of rice were found to increase significantly (p ≤0.05) with the increased rates regardless of kinds of organic treatments under both the moisture levels. The tallest plant heights (99 cm in moist, 105 cm in saturated condition) were recorded at maturity stage of rice with the RH8RS8SD8treatment, which received the highest rates of these three organic amendments. The shortest plant heights (79 cm in moist; 86 cm in saturated conditions) were recorded in control pot (RH0RS0SD0), where no amendment was made. The maximum numbers of tillers were observed in RH8RS8SD8followed by RH8RS8SD4, RH8RS4SD8, RH4RS8SD8 and RH4RS4SD8 treatments at saturated condition. The straw dry matter and grain yields of rice were also found to vary significantly (p ≤0.05) by the individual application of rice hull, rice straw, sawdust and moisture conditions, but their combined effects were found to be highly significant at their higher doses of combination. The highest grain yield (4.4 t ha-1) was recorded in RH8RS8SD8 treatment followed by RH8RS8SD4 (4.2t ha-1) and RH8RS4SD8 (4.1t ha-1) at saturated condition. Harvest index and 1000 grain weight of the rice were attained positive under both the moisture conditions, but at saturated condition of the soil, the amendments (RH, RS and SD) produced better response for these components compared to those of the moist soil condition.
