to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...

the experiment in this study was conducted as a completely randomized block design with ten treatments and four replications. treatments included: to- control, t1- 50g of zn per tree as broadcast application, t2-100g zn per tree, broadcast application, t3- 200g zn per tree as broadcast application, t4- 50 g zn per tree as band application, t5- 50g zn per tree, band application, t6-100g zn per t...

this experiment was conducted to investigate the effect of salinity and aba foliar application on growth and physiology of two canola varieties (fornex and okamer). salinity levels (0 and 12 ds/m) and aba foliar application (0, 15 and 30 µmol l-1) were investigated using a factorial split design in 3 replications. results showed variety fornex was salt stress tolerance variety. aba foliar appli...

background and objectives: drought stress is one of the most important environmental factors reducing growth and yield of crops, especially in arid and semiarid regions of the world. during drought stress, nutrient uptake diminishes due to rising of solute concentrations and so increasing of osmotic potential in the root zone. with increasing soil ph, micronutrient uptake decreases more than ot...

in order to evaluate the effects of irrigation levels and foliar application with fe and zn on quantitative and qualitative traits of red bean, an experiment was designed as split plot based on a completely randomized block design with three replications in lordegan country in summer 2011. irrigation as the main plot at three level such on: irrigation after 50, 75 and 100 mm evaporation, and fo...

in order to study the effects of soil and foliar application of fe-eddha on some biochemical and physiological traits in safflower under two irrigation regimes an experiment was conducted in 2008 growing season in research field of faculty of agriculture, shahed university. the experimental design was a split-plot based on randomized complete blocks with four replications. mainplots consisted o...

background & aim: this experiment investigated the effect of foliar application of methanol and ethanol on the biomass yield of medicinal plant echinacea purpurea. purple coneflower is an herbaceous perennial in the asteraceae family that is used in therapy of respiratory tract infection and bacterial otitis. experimental: this experiment was conducted in randomized complete block designed...
