In a 2yrs field study the effect of concentration and time of salicylic acid (SA) foliar application on growth of barley under non-saline and saline (2 and 12 dS m-1 of NaCl, respectively) conditions was evaluated in National Salinity Research Center of Iran, Yazd, central Iran during 2012-2014 growing seasons. The treatments of SA (11 treatments) included without SA and SA foliar application a...
wheat crop, considering its high planting area and consumption at national scale, demand a regular yield increase. humic acid, as an organic acid obtained from humus and organic sources without any environmental destructive effects, improves wheat yield particularly in variable environment conditions. in order to evaluate the effects of different levels of humic acid on shoot and wheat yield, a...
introduction half of the world's population suffers from micronutrients malnutrition. use of bio-fertilizers in sustainable agricultural systems is important in production and enables plants to absorb more water from soil and improves plant nutrient uptake and photosynthesis. benefits of vermicompost application in agriculture is due to its content of organic matter, plant nutrients and plant g...
