Morpho-physiological response of 7 rice (Oryza sativa L.) varieties viz., Moroberekan, Co39, Azucena, Bala, IR64, Kalinga-III and Nipponbare was assessed under control and 100 mol m NaCl + 5 mol m CaCl2 stress in a flood bench system in greenhouse. Physiological and growth parameters were recorded after 21 or 42 days of salt stress. The statistical analysis revealed significant differences amon...

Irrigation-induced salinization is an important land degradation process that affects crop yield in the Brazilian semi-arid region, and gypsum has been used as a corrective measure for saline soils. Fluvent soil samples (180) were treated with increasing levels of salinization of NaCl, MgCl2 and CaCl2. The salinity was gauged using electrical conductivity (EC). Gypsum was added to one split of ...

The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...

The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...

This experiment was conducted to determine the effect of salinity and nitrogen on growth and yield of tomato and concentration and total uptake of some nutrients in different parts of plant in hydroponics culture. Nitrogen (N) was used at 0, 1.5 and 3% levels as NH4Cl and NH4H2PO4 and salinity consisted of 0, 30 and 60 mM as NaCl and CaCl2 (2:1 w/w). A completely randomized design experiment wa...

intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...

In an effort to elucidate the physiological processes involved in cowpea differential growth response of four major USA cowpea cultivars (CB5, CB27, 8517 and 7964) to increasing salinity, we investigated the effect of salinity on leaf gas exchange of net photosynthetic rate per unit leaf mass (Pnm) and per unit leaf area (Pna), and stomatal conductance (gs) of the four cowpea cultivars. The exp...
