Determination of Crop Water Stress Index for Irrigation Scheduling of Turfgrass (Cynodon dactylon L. Pers.) under Drought Conditions
Abstract The crop water stress index (CWSI) is a valuable tool for monitoring and quantifying water stress as well as for irrigation scheduling. A field experiment was conducted during spring and summer 2012 at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, Iran, to determine CWSI of turfgrass for irrigation scheduling. Four levels of water regime...
متن کاملCrop Production under Drought and Heat Stress: Plant Responses and Management Options
Abiotic stresses are one of the major constraints to crop production and food security worldwide. The situation has aggravated due to the drastic and rapid changes in global climate. Heat and drought are undoubtedly the two most important stresses having huge impact on growth and productivity of the crops. It is very important to understand the physiological, biochemical, and ecological interve...
متن کاملRhizosphere manipulations to maximize 'crop per drop' during deficit irrigation.
Although much of global agriculture is rain-fed, production is frequently (and sometimes catastrophically) constrained by rainfall. Supplementary irrigation can stabilize yield from year-to-year and conventionally has aimed to meet full crop evapotranspiration (ET), since the relationship between ET and crop yield is near-linear at suboptimal water supply (Fereres and Soriano, 2007). Changes in...
متن کاملEffect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
