Wild jujube, Ziziphus lotus, is a multipurpose xerophytic shrub of the Rhamnaceae family widely distributed in arid and semi-arid regions of Tunisia, where it occupies most soil types. The fruit is the edible part of the plant by local population. The reintroduction of this shrub requires the control of its multiplication in response to water shortage. This study aims to evaluate growth and wat...
in order to investigate the effect of sodium nitroprusside (snp) application on yield and yield components of kidney bean under water deficit stress, a field experiment was conducted in split-factorial based on randomized complete block design with three replications in hamedan, in 2012. water deficit stress at four levels including vegetative stress, reproductive stress vegetative+reproductive...
Water deficit is the major abiotic factor limiting plant growth and crop productivity around the world (Kramer, 1983). Approximately one third of the cultivated area of the world suffers from chronically inadequate supplies of water (Massacci et al., 2008). In all agricultural regions, yields of rain-fed crops are periodically reduced by drought (Kramer, 1983), and the severity of the problem m...
Plant responses to water deficit are dependent on the amount of water lost, the rate of loss and the duration of the stressed condition. The characterization of a large number of genes induced by stresses involving water deficit has significantly improved understanding of the response. There appear to be several pathways for gene induction involved, and these are being elucidated by the analysi...
experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...
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 ...
the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...
At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
this study evaluates the effect of irrigation method on the water use efficiency and yield of onions at the zahak agricultural research station in sistan province. the testing was conducted using a split plot arrangement and a randomized complete block design with three replications during the 2005-2006 crop seasons. irrigation methods were basin and drip tape irrigation and the irrigation leve...
the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...
