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...

organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. one of these compounds is humic acid that was used widely in research and commercial programs. humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. in order to inves...

in order to study drought stress, zn and, fe foliar application on grain yield and yield components of sorghum (sorghum bicolar l .moench)in sistan region, an split plot experiment was carried out base on randomized complete block design with 3 replications during summer2010. three irrigation levels (normal irrigation, pre-anthesis drought stress and post-anthesis drought sress) ialocated in ma...

The effect of exogenous application; seed priming or foliar spraying of salicylic acid (SA) on Yecora Rojo and Paragon wheat cv. under NaCl-salinity. Gas exchange parameters, growth parameters, yield and yield components were reduced in both cultivars under salinity stress with foliar spray and soaking seeds. Exogenous application of SA through foliar spraying or seed soaking showed a slight in...

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...

Powdery mildew infection in cucumber plants was significantly reduced by foliar application of 2,6dichloroisonicotinic acid (INA). Although the overall isozyme banding patterns of superoxide dismutase (SOD) and peroxidase (POD) were very similar, there were differences in the densities of major bands between the leaves of control and INA-applied plants. When plants were subjected to foliar appl...
