This experiment was conducted to determine evapotranspiration, crop coefficient and water use efficiency of cucumber and tomato for a period of six months in the Resarch Greenhouse of Urmia University. Daily evapotranspiration of cucumber, tomato and reference crop was measured using lysimeter method. Based on the results, cucumber evapotranspiration for growth period of 130 days was 272.4 mm a...

In recent years, a lot of research has been done on the Aquacrop model, the results show that this model simulates the product performance for deficit irrigation conditions. But this model, like other models, is sensitive to values of independent variables (model inputs). In this research, the sensitivity of the Aquacrop model was analyzed for 4 input parameters of reference evapotranspiration,...

SUMMARY Diagnostic residual and partial residual plots are proposed to identify nonlinearity in covariates for generalized linear models. It is shown that these plots are complement each other in the detection of nonlinearity. In addition, a transformed additive model which allows the resulting residual and partial residual plots to be obtained through the standard least squares approach is pro...

Agricultural irrigation practices will likely be affected by climate change. In this paper, we use a statistical model relating observed water use by U.S. producers to the moisture deficit, and then use this statistical model to project climate changes impact on both the fraction of agricultural land irrigated and the irrigation rate (m³ ha⁻¹). Data on water withdrawals for US states (1985-2005...

A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...

abstract- efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. this research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (wp) with different water management scenarios at farm level at ...
