Bu araştırmada, serada yetiştirilen hıyar bitkisinin yarı ıslatmalı sulama (YIS) ve geleneksel kısıntılı sulamaya (KS) tepkisinin belirlenmesi amaçlanmıştır. Çalışma, Türkiye’nin güneyinde Antalya koşullarında plastik örtülü cam olmak üzere iki farklı yürütülmüştür. Kontrol konu (K100) ile birlikte (KS75 KS50), ardışık-yarı (A-YIS75 A-YIS50) sabit-yarı (S-YIS75 S-YIS50) yedi konusu ele alınmışt...

an application of new irrigation methods to increase water use efficiency is essential, due to global water shortages, and as well a consumption of more than 70% of fresh water in the agricultural sector. in this study, the effect of full irrigation (fi), partial root-zone drying (prd) treatments at two levels (provision of 75% of et (prd75) and 55% of et (prd55)) vs. deficit irrigation treatme...

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...

Partial rootzone drying (PRD) is a new irrigation technique which improves the water use efficiency (by up to 50%) of wine grape production without significant crop reduction. The technique was developed on the basis of knowledge of the mechanisms controlling transpiration and requires that approximately half of the root system is always maintained in a dry or drying state while the remainder o...

in this study, the pattern of changes in the values of soil electrical conductivity (ec) and soil temperature (t) under full irrigation treatment (fi) as compared with prd75 and prd55 treatments (partial root-zone drying which received 75 % and 55% water of fi at each irrigation event) was investigated in 1389 on a maize filed in sari university of agricultural sciences and natural resources. r...

When soil moisture is heterogeneous, sap flow from, and ABA status of, different parts of the root system impact on leaf xylem ABA concentration ([X-ABA]leaf). The robustness of a model for predicting [X-ABA]leaf was assessed. 'Two root-one shoot' grafted sunflower (Helianthus annuus L.) plants received either deficit irrigation (DI, each root system received the same irrigation volumes) or par...
