Nutritional management is an important factor in the success of crop production. In order to evaluate different level of nitrogen, potassium and zinc fertilizers on agro physiological characteristics of green bean a field experiment was conducted as split-plot based randomized complete block design in three replications, in Varamin university field research during 2011. The main plot included u...

in order to determine the effects of zinc foliar application on the vegetative characteristics, yield and fruit quality in strawberry (fragaria × ananassa duch) cv kordestan under salinity stress conditions, an experiment was carried out hydroponically in glasshouse as a controlled environment during 2009 through 2010. three levels of nacl (0, 15, 30 mm) and three levels of zn (0, 1.5, 3 g/l) w...

Fertilizer was applied annually for eight years to individual ramets in a loblolly pine (Pinus taeda L.) seed orchard at rates ranging from 0 to 448 kg nitrogen (N) ha(-1) year(-1). Clonal effects accounted for a major source of variation in both flowering and foliar nutrient concentrations. Foliar N concentrations were generally correlated with the intensity of fertilizer application, but were...

this experiment was carried out to evaluations the allopathic foliar application of safflower)carthamus tintorius) aqueous extracts on growth and leaf cell membrane leakage of hairy vetech (vicia villosa).  the experimental arrangement was crd in four replications. results showed that by increasing the concentration of safflower extracts, shoot dry weight and peroxidase enzyme activity decrease...

effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...

in order to investigate the effect of sodium nitroprusside (snp) application on yield and yield components of kidney bean under water deficit stress, a field experiment was conducted in split-factorial based on randomized complete block design with three replications in hamedan, in 2012. water deficit stress at four levels including vegetative stress, reproductive stress vegetative+reproductive...

several species of phytophthora cause crown and root rot diseases of herbaceous and woody plants. crown and root rot of pistachio trees cause significant damages in infected orchards. the effect of foliar application with elite (fosetyl-al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. the frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...

to study the effect of foliar application of humic acid on morpho-physiological traits, nutrients uptake and postharvest vase life of cut marigold, an experiment was conducted with five levels of humic acid (0, 250, 500, 750 and 1000 ppm) based on completely randomized design with three replications. based on the results, in compared with control, leaf number and leaf area, total phenol and aer...

to evaluate the effects of pgpr foliar spraying on forage and grain yield of forage sorghum (var. speedfeed), a farm experiment was conducted in research farm of college of agriculture, university of tehran in 2009. the experimental design consisted of a randomized complete blocks consisting of 17 treatments in every block. in this research, the effect of foliar application of 16 different stra...
