Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The biosynthesis of secondary metabolites in medicinal and aromatic plants is affected by abiotic stresses such as water deficit. This study was carried out to evaluate seed yield and essential oil of dill under five irrigation dis...

abstract due to limited water resources in agriculture, application of each strategy to economize water use and increase area under cultivation is very important. one such strategy is deficit irrigation. for optimal planning of deficit irrigation, it is necessary to determine different sensitive stages of plant water shortages. in this study the effect of deficit irrigation on growth and yield ...

Water deficit is one of the most important difficulties, in which happes in dry zone and half dry zones.Water deficit, as the determinative factor, determinates the growing and extension of the plant cover inthese areas. Using the supper attractive, may reduce the production in the crops and control the plantcover in face of dry stress and water deficit. In this paper, the effect of supper attr...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

Cotton is one of the major crops cultivated in the Texas Rolling Plains region, and it is a major contributor to the regional economy. Cotton cultivation in this region is facing severe challenges due to an increase in the frequency of droughts and a projected decrease in rainfall in the future. Development and evaluation of deficit irrigation strategies for this region could potentially conser...

deficit- irrigation is one of the measures for water saving and optimum application of water in surface irrigation. however, lack of enough evidences, doubts on the proper application of deficit- irrigation, dissemination of research results and its application by the farmers are of practical challenging issues. this paper summarizes and analyzes some research results on deficit- irrigation in ...

The agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model was calibrated and validated to simulate water–salt transport based on field experiments in an arid region of China. The simulation results show lower soil water content but higher salt concentration under deficit irrigation. Soil water and salinity below 95 cm at 80% evapotranspiration (ETc ) treatments and 65 cm at 60% ETc treatme...
