Response of different rice cultivars (Oryza sativa L.) to water-saving irrigation in greenhouse conditions
Due to increasing water and growing demand for food a more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving condition...
متن کاملIrrigation water resource in a rice-growing area: economic evaluation under different pricing conditions
Water Framework Directive (60/20000/EC), in order to assign an appropriate cost to irrigation water resource, urges member states to introduce the concept of full cost and to adopt economic instruments to improve the efficiency of its allocation. The option to apply a volumetric supply fee promoting the rationalization of the resource, could thus play a role in addressing emerging and future pr...
متن کاملEffect of controlled drainage in the wheat season on soil CH4 and N2O emissions during the rice season
The effect of draining crop fields during the wheat season on the soil CH4 andN2O emissions during the rice season in this article. There were four treatments:traditional cultivation during the wheat season + cultivation without fertilizationduring the rice season (CK1 field), traditional cultivation during the wheat season +traditional cultivation during the rice season (CK2 field), draining t...
متن کاملUptake and Bioaccumulation of Heavy Metals in Rice Plants as Affect by Water Saving Irrigation
To reveal the impact of Non-Flooding controlled Irrigation (NFI) on the bioavailability and bioaccumulation of metals (Cu, Pb, Cd and Cr) in rice fields, metals concentration in different organs of rice plant growing under both Flooding Irrigation (FI) and NFI were measured. It indicated that metals concentrations in root are always the highest one among all the plant organs and in the spike is...
متن کاملWater saving in rice-wheat systems
Water shortage is a major constraint to sustaining and increasing the productivity of rice-wheat systems. Saving water can be elusive in that reducing seepage, percolation and runoff losses from fields does not necessarily save water if it can be recaptured at some other temporal or spatial scale, for example by groundwater pumping. Many technologies appear to save substantial amounts of water ...
