plant performance and freshness is related to the pattern of its root growth development, which is highly affected by the water amount and water use management. therefore, the spatiotemporal variation of maize root under five treatments including full irrigation treatment (fi), partial root-zone drying treatments at two levels (receiving 75% of et =prd75, and 55% of et= prd55) and deficit irrig...
Water scarcity causes production losses in arid and semi arid regions. In this condition, deficit irrigation is one of the most important methods to minimize effects of water shortage. This research was conducted to evaluate the effects of two kinds of irrigation management (deficit irrigation and partial rootzone drying technique) on some of physiological and phenological characteristics and w...
Abstract In order to study the effect of water deficit stress on some physiological characteristics including leaf water osmotic and turgor potentials and osmolytes including sugars, proline and invertase activity of Persian melon (Cucumis melo Group. cantaloupensis cv. samsoury), an experiment was conducted in complete randomized design. Treatments including three irrigation levels (start of ...
an application of new irrigation methods to increase water use efficiency is essential, due to global water shortages, and as well a consumption of more than 70% of fresh water in the agricultural sector. in this study, the effect of full irrigation (fi), partial root-zone drying (prd) treatments at two levels (provision of 75% of et (prd75) and 55% of et (prd55)) vs. deficit irrigation treatme...
