Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture
Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

Stochastic order-based optimal design of a surface reservoir–irrigation district system
This paper explores the effects of streamflow uncertainty and the type of stochastic order, which is used for comparing stochastic variables, on optimal design of a reservoir multi-crop irrigation district system. Four nonlinear mathematical programs with an economic objective function including deterministic, stochastic-EXP with expected value order, stochastic-SD with stochastic dominance ...

Irrigation polyethylene pipe
Modern irrigation systems give maximum productivity and efficiency from water, and play an important role in the production of agricultural products. One of the main elements in the modern irrigation system is the use of polyethylene pipes to transport water. In this article, we will examine the features and benefits of using ldpe pipe (low density polyethylene pipe) and we will examine how to ...

Enhancing Crop Yield through Advanced Irrigation Controllers
Introduction Agriculture is the lifeblood of our civilization, providing sustenance and resources essential for human survival. In the pursuit of sustainable and efficient agricultural practices, advanced irrigation controllers have emerged as a transformative technology with the potential to enhance crop yield while promoting water conservation. This article explores the multifaceted role of ...

Site-specific nitrogen and plant density management in irrigated maize
Economic or environmental benefits resulting from variable-rate (VR) application of N and seed are uncertain in irrigated maize (Zea mays L.) systems with high yield potential. We evaluated different plant population and N management strategies in two irrigated maize fields in Nebraska. Inputs were varied according to yield zones derived from yield maps, detailed maps of soil organic matter ...
