in this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stags on chlorophyll content, yield and yield components of canola plant was investigated. for the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µm) during two different growing stages (first time; when temperature was close to 7-10 °c...

The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...

irrigation water and nitrogen fertilizer are two important factors in increasing the yield and yield components of cotton. in order to evaluate effects of irrigation methods, various levels of water and nitrogen fertilizer on yield and yield components of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plots design with th...

a experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...

In this study effect of irrigation managements including irrigation after 100 and 200 mm pan evaporation as normal and deficit irrigation respectively was investigated in Roselle plants. Effects of humic acid (including 0 and 4 kg ha-1) and mycorrhizal inoculants (including Glomus versiforme (GV) and Rhizophagus irregularis (RI)) were also studied on growth, yield and mycorrhizal symbiosis inde...
