abstract     the major constraints of agricultural production in the south western coastal areas of bangladesh are soil and water salinity of varying degrees, lack of fresh water for irrigation, slow soil drying pattern which are being augmented further due to climate change, requires suitable options of farming systems and component technologies. the major constraints and potentials of agricul...

abstract in this study, evaluation of swap model in simulating crop yield, water and salt movement in soil were investigated in the wheat- fodder maize cultivated units. the research was conducted in the voshmgir network, golestan province. the crop yield, soil humidity and moisture data in different times of agriculture year of 2007-2008 were measured. the measured and simulated data were anal...

Salinity is one of the most important stress factors in crop production, particularly in arid regions. This research focuses on the effect of salinity on the growth of lettuce plants; three solutions with different levels of salinity were considered and compared (S1 = 50, S2 = 100 and S3 = 150 mM NaCl) with a control solution (Ct = 0 mM NaCl). The osmotic potential and water content of the leav...

Among abiotic stresses, high salinity stress is the most severe environmental stress, which impairs crop production on at least 20% of irrigated land worldwide. In response to high salinity stress, various genes get upregulated, the products of which are involved either directly or indirectly in plant protection. Some of the genes encoding osmolytes, ion channels, receptors, components of calci...

this study was carried out in order to evaluate allelic diversity of microsatellite markers in qtl region for salinity tolerance on chromosome 10 in rice and evaluation of agronomical traits of some iranian rice cultivars in salinity stress along with two tolerant (pokkali) and sensitive (ir29) check varieties, and association analysis for morphological traits using microsatellite markers.based...

Whilemany studies of non-native species have examined either soft-bottom or hard-bottom marine communities, including artificial structures at docks andmarinas, formal comparisons across these habitat types are rare. The number of nonindigenous species (NIS) may differ among habitats, due to differences in species delivery (trade history) and susceptibility to invasions. In this study, we quant...

Molecular and physiological traits imparting resistance/tolerance and susceptibility to a particular biotic and abiotic stress are important from crop production point of view. There are a number of biotic (viz., insect-pests and diseases) and abiotic stresses (viz., drought, water logging, salinity/alkalinity, low temperatures etc.), which affect crop, among abiotic stresses, high salinity str...

Electrocardiography (ECG) may be used to recognize cardiac disorders. Levels of milk production may change the serum electrolytes which its imbalance has a role in cardiac arrhythmia. Fifty high yielding and fifty low yielding Holstein dairy cows were used in this study. Electrocardiography was recorded by base-apex lead and blood samples were collected from jugular vein for measurement of seru...
