Deficient irrigation is a very significant study, especially with the limited water. Therefore, current research aims to study deficit depending on several different scenarios, by adding amounts of water and rates (10%, 30%, 50%, 70%, 90%) full changing time studying its effect productivity. The results showed that there clear productivity barley at level (10%-30%) for all dates when date first...

Despite the importance of Artemisia annua L. as the only source of the anti-parasitic drug artemisinin, little is known on the effects of biotic and abiotic stress on artemisinin accumulation. Water deficit is the most limiting factor on plant growth, however it can trigger secondary metabolite accumulation, depending on the plant growth stage and intensity. A. annua cultivated in growth chambe...

The present study was carried out at Sakha Agricultural Research Station (clayey soils) during 2018 and 2019 to find the role of water deficit on yield some relations for sorghum cowpea summer forage crops. Three irrigation levels were executed; 100% (full irrigation), 90% (10% deficit) 80% (20% deficit). Results showed that increasing deficit, markedly led decreasing fresh, dry plant height th...

in order to investigate the effect of hexaconazole (hex) on the increasing tolerance to water deficit stress of two soybean (glycine max l.) cultivars, an experiment was conducted in faculty of agronomy of tarbiat modares university as factorial experiment in randomized complete block design arrangement. factors examined in this study were included soybean cultivars (l17 and clark63), hex conce...

The extensive use of pesticides in agriculture is compromising soil and water quality. One major concern is protecting water resources from contamination. The main objective of this research was measuring 2,4- D in a silty clay soil and simulating temporal transportation of this herbicide in soil using a LEACHP model, in a corn root zone field. 2,4- D was applied at 3.5 kg a.i./ha, followed by ...

introduction grain legumes are considered as the second source of human nutrition after cereals and play an important role in community food supply, sustainable agriculture and economic profitability. among grain legumes, common bean has the most consumption in the world compared with others. however there are always some constraints in common bean production and drought is most important facto...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

water scarcity in arid and semi-arid climate of iran has made deficit irrigation as a strategy for optimal water use and conservation in agricultural sector. this study aimed at evaluating the effects of water-deficit stress and n fertilizer levels on sugar beet performance. the study was conducted in split block design based on randomized complete block design arrangement. the row factor consi...

crop models need more evaluation and study for use in deficit irrigation. the main objective of this paper was to study the efficiency and accuracy of dssat model, in estimating of moisture in the soil profile under two levels of water application¬¬¬ in silage maize field. two irrigation treatments including deficit irrigation (0.7 smd), and a full irrigation (smd) were considered for two years...
