Yield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملEffects of partial root-zone irrigation on hydraulic conductivity in the soil–root system of maize plants
Effects of partial root-zone irrigation (PRI) on the hydraulic conductivity in the soil-root system (L(sr)) in different root zones were investigated using a pot experiment. Maize plants were raised in split-root containers and irrigated on both halves of the container (conventional irrigation, CI), on one side only (fixed PRI, FPRI), or alternately on one of two sides (alternate PRI, APRI). Re...
متن کاملA review on partial root-zone drying irrigation
Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...
متن کاملRoot water potential integrates discrete soil physical properties to influence ABA signalling during partial rootzone drying.
To investigate the influence of different growing substrates (two mineral, two organic) on root xylem ABA concentration ([ABA](root)) and the contribution of the drying root system to total sap flow during partial rootzone drying (PRD), sunflower (Helianthus annuus L.) shoots were grafted onto the root systems of two plants grown in separate pots. Sap flow through each hypocotyl was measured be...
متن کاملWater use efficiency of controlled alternate irrigation on root-divided maize plants
A new method of irrigation was designed and tested for its water use efficiency (WUE). Maize plants were grown in pots with their roots divided and established into two or three separated containers of which irrigation and soil drying were controlled alternately. Results showed that when the two halves of the root system were alternatively exposed to a drying soil and a soil with its water cont...
