Nutrient acquisition and yield response of Barley exposed to salt stress under different levels of potassium nutrition
Abstract: A greenhouse experiment was carried out in 2002 at Jordan University of Science and Technology, Agricultural Experiment Station to examine the effect of potassium fertilization on the response of barley (Hordeum vullgare L.) to different soil salinity levels. Five levels of potassium (0, 0.2, 0.4, 0.6, and 0.8 g K per pot as KCl) and two salt levels (0.75 and 13 ds/m) were investigated ...

Regional-scale assessment of soil salinity in the Red river valley using multi-year MODIS EVI and NDVI
Received for publication April 15, 2009. The ability to inventory and map soil salinity at regional scales remains a significant challenge to scientists concerned with the salinization of agricultural soils throughout the world. Previous attempts to use satellite or aerial imagery to assess soil salinity have found limited success in part because of the inability of methods to isolate the effects ...

Perceptions and practices of farmers towards the salinity problem: the case of Harran Plain, Turkey
The Harran region, located in the South-eastern part of Turkey, is facing an increasing salinity problem due to excessive and inefficient irrigation practices. In this paper, we survey 619 cotton producers in the region and analyse their perceptions and practices towards soil salinity. The survey results indicate that formal education and training are the central factors that determine the ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil
Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the bacterial exo-polysaccharides (EPS), however, such a role of the EPS-producing bacteria in the saline environments has rarely been investigated. Pot ...

Minimal models and agroecological policy at the regional scale: An application to salinity problems in southeastern Australia
A minimal dynamical systems model that couples agricultural activity, native vegetation, and hydrological processes is developed to explore policy options regarding regional-scale soil and water salinization in southeastern Australia. The analysis suggests that although considerable revegetation is required to restore catchment water balance, the current value of water in uses other than ...

Optimizing Crop Yield with Soil EC Sensors
Introduction: Crop yield optimization is a key goal for farmers, as it directly impacts their profitability and food production capacity. Soil EC sensors have emerged as a valuable tool in precision agriculture, helping farmers make informed decisions regarding nutrient management and irrigation practices. In this article, we will explore the benefits and applications of soil EC sensors in ...

Water Stress
Plants experience water stress either when the water supply to their roots becomes limiting, or when the transpiration rate becomes intense. Water stress is primarily caused by a water deficit, such as a drought or high soil salinity. Each year, water stress on arable plants in different parts of the world disrupts agriculture and food supply with the final consequence: famine. Hence, the ability ...

Soil salinity and exchangeable cations in a wastewater irrigated area, India
Received for publication May 29, 2008. The salinity and cation composition of water and soil were documented in a large (98 km2) wastewater-irrigated area (WIA) downstream of Hyderabad, India. The wastewater, which flows in a river that passes through the city, had a high to very high salinity hazard (EC = 1.1–3.0 dS m–1) that increased with distance from the city. The EC of soil irrigated by ...

Types and maintenance of soil salinity sensors
Background: When people think of salt in relation to crops, the impression is that salt is bad for plant growth. However, it must be remembered that whenever we apply fertilizer, we are adding salt to the soil. So, when measuring soil salt, it can be a case of too much or too little. If the salinity is too high, the roots cannot absorb water. If the salinity is too low, the plants may lack ...

Salicylic acid for plants.
In reality the use of salicylic acid for plants has several benefits. In 1933, salicylic acid (SA) was first proposed to develop acquired immunity after disease infection. However, most of our knowledge about plant immune signalling has mainly been recent after it was found that salicylic acid (SA) is defence signal derived from within the plant. So what is this novel plant biostimulant? SA show ...

Salinization/sodification of soil and physiological dynamics of sunflower irrigated with saline–sodic water amending by potassium and farm yard manure
Sunflower (Helianthus annuus L.) plants were grown with saline–sodic water (SSW) by treating with potassium (K @ 100 and 200 mg K2O kg−1 soil) and farm yard manure (FYM @ 5 and 10% of soil, w/w). Irrigation with untreated SSW caused soil salinization/sodification, leading to an increase in electrical conductivity (EC) of 165% and sodium adsorption ratio (SAR) 100% with the subsequent increase ...

Distribution of moisture and salinity under deficit irrigation and irrigation water salinity in an alternative trickle irrigation system of tape
This study was performed to investigate the horizontal and vertical distribution of soil moisture and salinity using an alternative trickle irrigation system of drip tape. Four main treatments consisting of 100, 80, 70, and 60% of the plants’ water requirements and three sub-treatments of 2.1, 4.6, and 10.2 dS/m, were conducted. Following irrigation, the soil moisture and salinity ...

The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip
The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

Salinity effects on seed germination and plant growth of guar
The potential of guar [Cyamopsis tetragonoloba (L.) Taub.] as a feasible crop for saline soils was tested in this study by evaluating seed germination of 42 accessions of guar in sodium chloride (NaCl) solution. The seeds were germinated in 200 mM NaCl or double-distilled water (control). There were significant differences in salt tolerance among the accessions tested. Percentages of seeds ...

Furrow seeding with plastic mulching increases stand establishment and lint yield of cotton in a saline field
Uniform stand establishment is essential for profitable cotton (Gossypium hirsutum L.) production in saline fields. This study was conducted during 2003 and 2004 to determine if furrow-bed seeding and plastic mulching improve stand establishment and cotton lint yield in a saline field. The experiment was arranged in a split-plot design with seeding patterns (flat-seeded and furrow-seeded) as main ...
