Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
In order to evaluate the effect of row and plant spacings on the yield and yield components of three cultivars of forge sorghum, a field experiment was conducted in Isfahan University of Technology, Lavark, during spring, 2001. Experimental design was a split-factorial with three replications. Main plots consisted of three row spacings (45, 60, 75 cm) and subplots were combinations of three cul...
A greenhouse experiment was conducted to evaluate the effect of nitrogen (N) and salinity on dry matter yield, N uptake, nitrate (NO3-) concentration, agronomic efficiency (AE), physiologic efficiency (PE), apparent nitrogen recovery (ANR) and chlorophyll content of spinach shoots (cv. Viroflay), and also total N, NO3-N and electrical conductivity of post-harvest soil. The experiment was factor...
Red light-emitting diodes (LEDs) are a potential light source for growing plants in spaceflight systems because of their safety, small mass and volume, wavelength specificity, and longevity. Despite these attractive features, red LEDs must satisfy requirements for plant photosynthesis and photomorphogenesis for successful growth and seed yield. To determine the influence of gallium aluminium ar...
Heavy metal stress is one of the key factors for crop yield along with other abiotic stresses such as drought, salinity, extreme temperature and light. Due to natural and anthropogenic activities heavy metal pollution is increasing daily. Hence, it is must to know the effects of heavy metals in depth on crop growth and development ultimately yield levels. In the present work we assessed the imp...
Long-term use of drip irrigation technology may lead to root degradation and affect shoot growth and yield. A field experiment was conducted to investigate aboveand belowground growth responses to drip irrigation under mulch film (DI) in comparison to flood irrigation under mulch film (FI) in cotton. The monolith method was used to harvest roots at seven timepoints in the growth periods, and th...
This research was performed in 2011 at University of Mohaghegh Ardabili, Iran, to evaluate osmotic-stress tolerance, at seedling stage, of rapeseed (Brassica napus L.), as a split plot experiment based on randomized complete blocks design with four replications. Levels of osmotic stress were considered as main factor and twelve rapeseed cultivars were sub-factor, that were evaluated under aquac...
in order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the research institute of forest and rangelands, karaj, iran, in 2013-14. the treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). the experimental design was a factorial experiment based on randomized ...
evaluation of essential oil yield, morphological and phenological traits of seven populations of twochamomilespecies )matricaria aurea and m. recutita), were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-2012. data were collected for 12 morphological and phenological traits. analysis of variance showed si...
Translocation of micronutrients was investigated in Phaseolus vulgaris (var. Annapurna) grown on soil amended with paper mill sludge. The plants of P. vulgaris were grown in soil amended with 20%, 40%, 60%, 80%, and 100% paper mill sludge to study the accumulation and translocation of iron (Fe), zinc (Zn), cadmium (Cd), copper (Cu), chromium (Cr) and lead (Pb) in plant parts (shoot, root, leave...
