Regulated Deficit Irrigation Improves Yield Formation and Water and Nitrogen Use Efficiency of Winter Wheat at Different Soil Fertility Levels

Agronomy
Water scarcity and spatial variability in soil fertility are key constraints to stable grain production in the Huang-Huai-Hai Plain. However, the interaction mechanisms between regulated deficit irrigation and soil fertility influencing yield formation ...

Irrigation scheduling and regulated deficit irrigation in stone fruits

Proceedings of the 4th Workshop on Agri-Food Research. WiA
In recent years the interest for applying irrigation techniques aiming to reduce water consumption has increased, mainly in areas with scarce water resources. We studied the effect of different regulated deficit irrigation (RDI) strategies on peach (Prunus persica (L.) Batsch cv.

The Physiological Mechanism of Coupled Regulation Between Water Deficit Severity and Deficit Period on Winter Wheat Yield

Agronomy
Regulated deficit irrigation is a vital method for developing water-saving agriculture. The degree of and the period of water deficit are two key factors determining the effectiveness of regulated deficit irrigation.

Assessing the impact of deficit irrigation strategies on agronomic and productive parameters of Menara olive cultivar: implications for operational water management

Frontiers in Environmental Science, 2023
The olive tree is an iconic tree in the Mediterranean region, traditionally cultivated under rainfed conditions; however, olive cultivars are also found outside the Mediterranean region and are widely used for oil and olive production.

The Mechanism of Regulation of ‘Bartlett’ Pear Fruit and Vegetative Growth by Irrigation Withholding and Regulated Deficit Irrigation

Journal of the American Society for Horticultural Science, 1986
Abstract After initially withholding irrigation (WI) to dry out the root zone of pear trees, regulated deficit irrigation (RDI) applied to replace 23% and 46% of evaporation over the planting square (Eps) was compared with 69% and 92% Eps applied during the WI and RDI periods, respectively (full irrigation ...

Irrigation of pear (A review)

International Journal of Horticultural Science, 2009
The plantation of intensive growing orchards and steady increase in yield is essential to return the growing cost by sale. Seasonal crop fluctuation of pear is increased by the frequently occurrence of drought and climatic changes.

Effects of regulated deficit irrigation on crop water productivity, yield components, and yield response factor of common bean (Phaseolus vulgaris L)

Central Asian Journal of Water Research, 2022
Due to declining water resources allocated to agriculture and rapid population growth, it is important to use water efficiently and increase crop water productivity (CWP). Deficit irrigation is considered an important strategy to achieve this goal.
