New Strategy for Optimizing Water Application under Trickle Irrigation
The determination of water application parameters for creating an optimal soil moisture profile represents a complex nonlinear optimization problem which renders traditional optimization into a cumbersome procedure. For this reason, an alternative methodology is proposed which combines a numerical subsurface flow model and artificial neural networks ~ANN! for solving the problem in two, fully s...
متن کاملWater-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes
The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...
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...
متن کاملResponse 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...
