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...

As sugar beet source leaves lowered the CO(2) concentration to compensation point in a closed atmosphere, leaf thickness and relative water content decreased. Leaf water potential declined rapidly from -0.5 to -1.4 megapascals. At 340 microliters CO(2) per liter, water potential and sucrose, glucose, and fructose contents were steady in photosynthesizing source leaves. Within 90 minutes after l...

Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate t...

in this research, some of the echo-physiological characteristics of pistachio trees were studied to understand crop response to drought stress and determine the best irrigation interval. this experiment was carried out in an orchard with a sandy loam textured soil and a commercial cultivar of pistachio named ouhadi grafted on pistacia vera l. rootstock for three years. the irrigation system sel...

drought stress is one of the most important problems of agriculture and an important factor of plant product reduction. application of absorbent materials can help usage of sporadic rain fall and cause more maintenance of water storage. in order to study the effect of super absorbent polymer, potassium sulfate and manure under drought condition and favorable irrigation on some traits of foxtail...

Six months-old seminal plants of 36 cacao genotypes grown under greenhouse conditions were subjected to two soil water regimes (control and drought) to assess, the effects of water deficit on growth, chemical composition and oxidative stress. In the control, soil moisture was maintained near field capacity with leaf water potentials (ΨWL) ranging from -0.1 to -0.5 MPa. In the drought treatment,...
