Background: Hyssop (Hyssopus officinalis L.) is herbaceous perennial plants of Lamiaceae family grown in Europe, the Middle East, Asia, and Northern Africa. Objective: In this research, the effect of harvesting time was studied on essential oil, photosynthetic pigment, and some morphological characteristics of hyssop. Methods: A Field experiment was carried out during 2015/2016 at the Res...

in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...

ABSTRACT The objective of this study was to evaluate the effects saline water irrigation management strategies and potassium doses on concentration photosynthetic pigments, gas exchange, fruit production ‘BRS GA1’ yellow passion fruit. experiment carried out under field conditions using a randomized block design, with treatments based 6 × 2 factorial scheme, related six for (irrigation low-sali...

water deficient is one of the most important limiting factors in rapeseed (brassica napus l.) production in arid and semiarid areas speciallyiran, which is the best approach to deal with the introduction of resistant and compatible varieties to drought stress. the response of fourteen rapeseed cultivars to water stress was studied in a split plot experiment based on complete randomized block de...

the main objective in production of any rainfed crop, including barley farming is to increase water productivity along with stability in the production of the rainfed crop through improvement of the agronomic management including limited single irrigation (si) and sowing date (sd). in order to determine optimal si management and limited water allocation scenarios, a field experiment was conduct...

background & aim: thyme is common named thymus vulgaris l. belongs to lamiaceae family. thyme is a most important medicinal plant that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. experimental: determine optimum of harvest time this plant was done in a random block design with three replications was conducted in field islamic azad universi...

Drought stress is one of the most important abiotic stresses influencing performance of crop plants. Therefore, the identification or development of tolerant genotypes is of high importance for incorporating in cotton production. In this study to evaluate the effect of drought stress on some cotton traits, 5 improved cotton varieties were studied in a split plot design with three replications i...

Grain yield (GY) prediction for wheat based on canopy spectral reflectance can improve selection efficiency in breeding programs. Time-series information from different growth stages such as flowering to maturity is considered have high accuracy predicting GY and combining this multiple could effectively accuracy. For this, 207 cultivars lines were grown full limited irrigation treatments, thei...
