in this regard, the morphophysiologic and anatomic characteristics of six olive cultivars (nabali, feshomi, arbequin, zard, gordal and roghani) were investigated under drought. experiments were designed based on factorial and complete block random plot with two control treatments, -1.5 mpa stress and three replicates. the investigated factors were as follows: leaf area, specific leaf area, leaf...

Abstract:  In order to evaluate the effect of drought stress and salicylic acid on mineral content and some  physiological traits of soybean genotypes (Glycine max L.) a greenhouse experiment was conducted as factorial based on completely randomized design with three replications in Mohaghegh Ardabil University in 2014. The first factor consisted of three levels of water deficit (85%, 65% ...

An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
