this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...

Growth and production of agricultural crops are greatly affected by water shortage. Thus, yield enhancement under drought conditions is a major goal of plant breeding. Four commercial tomato cultivars (Imperial, Pakmore VF, Strain-B and Tnshet Star), a drought-tolerant breeding line (L 03306) and their hybrid combinations were selected in this study to evaluate drought tolerance and to develop ...

sesame could be an appropriate oilseed crop for water limited environments. this research was aimed at studying growth, leaf chlorophyll fluorescence, proline content, yield and yield components of sesame cultivars under different moisture regimes. a 4-replicate split plot rcbd field experiment was conducted at the lavark research farm, college of agriculture, isfahan university of technology, ...

2 The aim of this study was to establish threshold TGR and MDS values which could be 3 used in regulated deficit irrigation in future work. Three irrigation treatments were 4 performed during three seasons in a 37 year-old table olive orchard in Seville (Spain). 5 Control treatment was irrigated with 125% of the crop evapotranspiration. Regulated 6 deficit irrigation (RDI) treatments were perfo...

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...

Water stress and increasing soil salt concentration represent the most common abiotic constrains that exert a negative impact on Mediterranean vineyards performance. However, several studies have proven that deficit irrigation strategies are able to improve grape composition. In contrast, irrigation with saline waters negatively affected yield and grape composition, although the magnitude of th...
