Background & Aim:Jasmonic acid (JA) is regarded as endogenous regulators that play important roles in regulating stress responses, plant growth and development.Effect of foliar application of JA on the essential oil and oil chemical components of hyssop (Hyssopus officinalis L.) were investigated. Experimental:  This study conducted in a CRD with three replications and in experimental...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...

The objective of this study was to evaluate the ability foliar application potassium nitrate (KNO3) induce water deficit tolerance in sorghum plants (Sorghum bicolor cv. P898012) subjected at pre-flowering. experiment conducted under greenhouse conditions with 4 treatments: field capacity (FC), (WD), + KNO3 (FC KNO3), and (WD KNO3). Two applications 3% (m/v) were made, first on day zero stress ...

Deficiencies of essential vitamins, iron (Fe), and zinc (Zn) affect over one-half the world’s population. A significant progress has been made to control micronutrient deficiencies through supplementation, but new approaches are needed, especially reach rural poor. Agronomic biofortification pulses with Zn, Fe, boron (B) offers a pragmatic solution combat hidden hunger instead food fortificatio...

Soybean is one of the ten greatest crops in the world, answering for billion-dollar businesses every year. This crop suffers from insect herbivory that costs millions from producers. Hence, constant monitoring of the crop foliar damage is necessary to guide the application of insecticides. However, current methods to measure foliar damage are expensive and dependent on laboratory facilities, in...

In order to study the effect of foliar applications of micronutrients on yield, extraction oil production and chemical composition of pot marigold (Calendula officinalis), two experiments were conducted in the randomized complete block design with three replications in Shahrekord, Iran during two growing seasons 2014 and 2015. The objectives of this study were to determine the effects of foliar...

to investigate the physiological traits of corn in terms of lead contamination with iron spray, research factorial completely randomized design with three replications was conducted in the greenhouse. the treatments consisted four levels of lead (zero, 100, 200 and 400 mg kg-1 of soil), two hybrids of maize (sc260 and sc704) and four foliar applications of iron sulfate (0, 0.2, 0.4 and 6%). lea...

effect of different amounts of foliar- and soil- applied n were evaluated in a factorial arrangement of rcbd with three replications at the agricultural research station of gorgan in 2004-2005 growing season. two promising lines of bread wheat, two levels of foliar application of nitrogen (0 and 5%) at tillering and booting stage, with five rates of 0, 45, 90, 135 and 180kg n/ha as urea were us...
