Cytokinins may reflect soil water status and regulate rice (Oryza sativa L.) grain filling. This study investigated the changes in cytokinin levels in rice plants and their relations with grain filling under alternate wetting and drying irrigation. Two 'super' rice cultivars were field grown. Three irrigation regimes, alternate wetting and moderate soil drying (WMD), alternate wetting and sever...

Environmental stresses such as deficit irrigation and ultraviolet radiation can influence plant growth and development. Among the environmental variables, ultraviolet radiation is an important factor in plant response to other stresses, such as deficit irrigation. The purpose of this study was to investigate the effects of ultraviolet B radiation (UV-B), irrigation stress and combined effects o...

In this study effect of irrigation managements including irrigation after 100 and 200 mm pan evaporation as normal and deficit irrigation respectively was investigated in Roselle plants. Effects of humic acid (including 0 and 4 kg ha-1) and mycorrhizal inoculants (including Glomus versiforme (GV) and Rhizophagus irregularis (RI)) were also studied on growth, yield and mycorrhizal symbiosis inde...

Optimum irrigation is very important for nursery stock management of F1-hybrid oil palm (Elaeis guineensis Jacq.), constituting a major production cost. Generally, over watering of nursery stock can be a cause of loss of productivity. The aim of this study was to investigate the physiological and biochemical responses of oil palm nursery stock to reduced soil water content (SWC) and during the ...

To optimize irrigation, agronomists need to modulate crop water productivity (CWP) throughout phenology. We compared regulated deficit irrigation (RDI) and sustained (SDI) in chickpea (Cicer arietinum L. var. Blanoro), expecting RDI during vegetative growth (VG) enhance CWP, as opposed flowering (F) pod-filling (PF) stages. The effects of SDI on grain yield, plant height, weight, caliber, pods ...

In order to investigate the effect of deficit irrigation and chemical fertilizers on yield some physiological traits quinoa an experiment was conducted in 2019 as split plot based a randomized complete block design two locations (Mashhad Neishabour). Irrigation included, I0: full irrigation, I1: no at emergence stage, I2: stem elongation I3: flowering I4: seed setting stage. Fertilizer treatmen...

In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...
