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 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 ...
متن کاملComparing canopy temperature and leaf water potential as irrigation scheduling criteria of potato in water-saving irrigation strategies
Irrigation scheduling is important in irrigation water management. In this study, full (FI),deficit (DI) and partial root drying (PRD) irrigation strategies were applied in Agria and Ramospotato cultivars. Canopy temperature (CT) and leaf water potential (LWP) were assessed as thepotential tools for irrigation scheduling during the vegetative and productive growth stages.LWP varied between ca. ...
متن کاملBeet Cut-off Irrigation as Efficient Way in Water Saving
Under surface irrigation, particularly in clay soils cut-off technique is considered as one of the most practical way in saving irrigation water that traditional farmers could be easily implemented. Such farming way is processing through find out the optimum length of irrigation run at which watering should be stopped instead of irrigation till the tail end of the furrows or borders. Such proce...
