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...

abstract- maize production, which is ranked after wheat and barely in fars province, iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. therefore, proper planting method can improve irrigation water management. the objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...

Drylands cover about 40 % of the terrestrial land surface and account for approximately 40 % of global net primary productivity. Water is fundamental to the biophysical processes that sustain ecosystem function and food production, particularly in drylands where a tight coupling exists between ecosystem productivity, surface energy balance, biogeochemical cycles, and water resource availability...

Pasture performance of 924 dairy farms in a major irrigation district of Australia was investigated for their water use and water productivity during the 2015-2016 summer which was the peak irrigation period. Using satellite images from Landsat-8 and Sentinel-2, estimates of crop coefficient (Kc) were determined on the basis of a strong linear relationship between crop evapotranspiration (ETc) ...

BACKGROUND: While recognizing the economic obstacles that currently block widespread use, many concerned with improving agricultural productivity and food security in Sub-Saharan Africa (SSA) are focusing on fertilizer as a remedy for declining soil quality and stagnant yields. Some have suggested that SSA needs to increase fertilizer use from 9 to at least 30 kg/ha during the next decade. Othe...

A field soil water balance model is developed for non-ponded “aerobic rice” in North China Plain. Increasing water scarcity necessitates the development of irrigated rice systems that require less water than traditional flooded rice. The aerobic rice is an effort to save water in response to growing worldwide water scarcity with the pressure to reduce water use and increase water productivity i...
