“…This disagrees with published results where under salt stress, the increase in chloride uptake was accompanied by a decrease in shoots nitrate (Yadav et al, 2011). Further, sorghum labeled with 15 N urea and receiving continuously saline water (7 dS m -1 ) derived less N from fertilizers, as compared to less saline treatments (Al Ain et al, 2017).…”

In this study the aim was to evaluate alternative crops able to tolerate thefuture rise in salinity, likely to occur in the East Mediterranean coastal areas. For this, two genotypes of pearl millet (Tall and IP13) were submitted to saline conditions (4, 8, 12 dS.m-1 and 2 dS.m-1 as control) in a field trial. Water consumption using neutron probe technique, physiological response and the production were studied. The neutron probe technique showed that 96% of consumed water originated in the upper 0.45 m. As salinity increased, water consumption became shallower, suggesting a different root distribution. Physiological aspects related to plant height, foliar potassium and uptake of nitrogen were investigated. Tallest plants were found in 4 dS.m-1 in Tall, and in 2 dS.m-1 in IP13. Foliar potassium was similar in Tall variety, while IP13 excluded the potassium, in order to reduce cellular ions. In Tall the 15N technique showed that 40-50% of plant N originated from the fertilizers, irrespective of saline conditions. Fresh weight was not different between 4 and 8 dS.m-1, in three cuts out of five in 2016 and 2017. Tall produced higher dry matter, especially under saline conditions. Best water use efficiency was in 4 dS.m-1 (10.4 kg.m-3 in Tall; 8.8 kg.m-3 in IP13). The plotting of dry matter production against salinity gave quadratic equations, with a peak at 5.6 dS.m-1 for IP13 and 7.1 dS.m-1 for Tall. Tall can be used for phytoremediation of soils in coastal areas, and as a forage crop.

“…As a recognition of the importance of using brackish water for irrigation in the CCRs where fresh water is becoming scarce (Knox et al, 2010;Vu et al, 2018), scholars have explored the studies regarding the utilization of brackish water for agricultural irrigation (Farid et al, 2017;Rahman et al, 2015). For example, Anízio et al (2020) studied the relationship between biochemical indicators and the yield of sugarcane RB 92579 variety in Recife, Brazil.…”

Background: Globally, irrigation water deficit (IWD) due to saline intrusion and decreased rainfed continues to affect coastal cultivation regions (CCRs). Coastal lowland regions have increasingly frequent saline intrusion, resulting in the IWD as a part of climate variability. Cu Lao Dung Isle, a terrain-low coastal plain in Vietanm is facing revenue loss due to adverse cultivation conditions in recent years. Methods: The objective of this study was, therefore, to assess the effectiveness of the mixture of brackish and freshwater (MBF) for irrigating the spring crop sugarcane in the 2019/20 season grown in a household farming in Cu Lao Dung Isle. An experiment was exploded with the MBF varying from 1.5 to 5.0 dS m-1 corresponding to 100 and 120% of the crop evapotranspiration (ETc). Determination of daily ETc was conducted simulating the FAO-Penman Monteith model based on the weather data obtained using an automatic weather station, locating in the study area. Result: Based on the findings, the MBF at 3.0 dS m-1 levels corresponding to 120% of ETc was stated to be suitable for normal growth of sugarcane Khonkaen III variety. The results showed that the MBF of increasing levels varying from 3.5 to 5.0 dS m-1 significant influenced the growth process and yield of sugarcane. In general, the utilization of brackish water for irrigating in the CCRs is a suitable solution for economic efficiency.

“…Different organic fertilizers are used in the agriculture of dry tropics, depending on their availability [7]. Manure has been used for centuries, as well as green manure resulting from tree pruning [8]. The combination of both has been little practiced and studied [1], although it may have the advantage of the difference in the decomposition rate and concentration of nutrients.…”

Soils in the semi-arid region of northeastern Brazil have low natural fertility and therefore, plant growth and productivity can be adversely affected. The application of mineral fertilizers is economically unfeasible by farmers in this region. The use of organic inputs found in farms, such as animal manure and the biomass of gliricidia leaves and branches (Gliricidia sepium Jacq. Walp), is a viable and low-cost option. Thus, the objective of this study was to evaluate influence of organic fertilizations over six years on the physical and chemical characteristics of a Fluvic Entisol cultivated with beans, cotton, corn and sunflower was evaluated. Fertilizations, of 20 Mg ha -1 year -1, were: GIsoil-incorporated gliricidia; GS -surface gliricidia; EI + GI -manure and incorporated gliricidia; EI + GS -soil -incorporated manure and surface gliricidia, EI -soil -incorporated manure; and controlwithout addition of organic fertilizer. In the combined applications, half the fertilizer came from each source. All fertilization systems decreased bulk density, compared to the control treatment, and in the EI + GS system, there was an increase in total soil porosity. The GS system resulted in the largest SOM stocks and C / N ratio. The EI + GI system increased the total phosphorus stock. The use and application of gliricidia biomass as a green fertilizer over time improves the soil physical and chemical conditions, promotes good agricultural productivity without the need of mineral fertilizers, being an alternative of high relevance in the reduction of costs in agricultural practices.
