ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...

in recognition of the value and limitations of available water resources in agriculture and the occurrence of periodic drought in iran, water conservation and optimal usage of available water is essential. the main objective of this study was to optimize field water management and cropping patterns using deficit irrigation. the effect of reducing water consumption on different growth stages usi...

this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...

This research proposes A THEORETICAL FRAMEWORK based on model predictive control (MPC) for irrigation control to minimize both root zone soil moisture deficit (RZSMD) and irrigation amount under a limited water supply. We (i) investigate means to incorporate direct measurements to MPC (ii) introduce two Robust MPC techniques e Certainty Equivalence control (CE) and Disturbance Affine Feedback C...

sustainable agriculture for producing food is not possible without optimal use of water resources. because of the limitation of water resources, deficit irrigation would be essential to increase water productivity. in order to evaluate the effects of deficit irrigation on quality and quantity of sugar beet, an experiment was carried out in a farm in miandoab agricultural research station for 2 ...

concerning limitation of water resources, determination of the least water that can lead to the maximum yield is of great importance in crop production. in order to evaluate effects of deficit irrigation on grain yield and water use efficiency of some wheat )triticum aestivum) cultivars under different climatic conditions, two similar field experiments were conducted in 2004 in agricultural res...

the responses of isabgol (plantago ovata forsk.) to micronutrient foliar application under low irrigation condition were investigated. the experiment was carried out in agricultural research farm of zabol university, iran, during growing season of 2007-2008. the experiment was conducted in spilt plot using randomized complete block design with four replications. three irrigation regimes defined...
