The measurement of evapotranspiration is the most important factor in irrigation scheduling. Evapotranspiration means loss of water from the surface of plant and soil. Evaporation parameters are being used in studying water balances, water resource management, and irrigation system design and for estimating plant growth and height as well. Evapotranspiration is measured by different methods by ...

proper irrigation scheduling, i.e. timely and adequate irrigation is an important prerequisite to profitable crop production. high temperatures along with soil moisture deficits are some of the main limiting factors for canola (b. napus l.) production in dry land cropping systems. these factors negatively affect the formation of pods during the flowering stage, resulting in decrease in seed yie...

Cotton is one of the major crops cultivated in the Texas Rolling Plains region, and it is a major contributor to the regional economy. Cotton cultivation in this region is facing severe challenges due to an increase in the frequency of droughts and a projected decrease in rainfall in the future. Development and evaluation of deficit irrigation strategies for this region could potentially conser...

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 ...

Irrigation scheduling techniques is one of the suggested solutions for water scarcity problem. The study aims to show possibility using practical and applicable irrigation program which was designed by Water Resources Department at University Baghdad Spreadsheet Formulas Microsoft Excel program, version 2007, with some modification generalize it made various climatic zone different soil types, ...
