Abstract The global climate changes and their influence on agriculture in Uzbekistan were analyzed, including problems of irrigation water shortage irrigated lands the lower reaches Amu Darya with greatest due to repeated dry years. Additionally, recommendations for effective use resources conditions meadow alluvial soils salinization shallow salinized groundwater proposed subirrigation drip ir...

abstract to study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. analysis of variance showed considerable variation among cultivars. water stress reduced all of the studied morphological characteristics, espe...

Preharvest conditions, including photoperiod and irrigation regime, affect the keeping quality of long stem roses (Rosa x hybrida). Rose plants cultivar ‘Charming Black’ were subjected to four different treatments investigate how nocturnal supplemental lighting regimes influence post-harvest performance. Vase life, ornamental quality, water balance, petal color, vacuolar pH, soluble sugar conte...

Due to climate change, the application of water saving strategies is of particular interest. The aim of this study was to evaluate the effects of deficit irrigation (DI) and partial root-zone drying (PRD) techniques on the crop water stress index (CWSI), water use efficiency (WUE), and quality parameters in processing tomatoes grown in open field conditions in a Mediterranean climate. Two culti...

The primary natural source of water for the Hass avocado crop in tropics is precipitation. However, this insufficient to provide most crops’ requirements due spatial and temporal variability. This study aims demonstrate that requires irrigation Colombia, done by analyzing dynamics local precipitation regimes influence Intertropical Convergence Zone phenomena (ITCZ) on requirement (IR). was carr...

to investigate the effect of supplemental irrigation and nitrogen fertilizer on kernel weight, test weight and wheat grain yield under dryland conditions, a two-year field experiment was conducted in the research farm of college of agriculture, shiraz university during 2004-2005. five irrigation regime including dryland conditions, irrigation at stem elongation, booting, flowering and grain fil...
