glasswort(salicornia europaea l.) as an important halophyte plant is capable to accumulate nacl in aboveground part (fully edible) in considerable quantity. to evaluate the effect of irrigation levels and nitrogen fertilizer on the yield of seed and oil, and also harvest index of glasswort, a split plot experiment was conducted based on randomized complete block design with three replications a...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

ABSTRACT Biostimulants currently available on the market include those containing seaweed extract. There is sufficient scientific evidence to conclude that applying biostimulants agricultural crops can positively impact plant growth and yield. However, results differ between plants species environmental conditions. As such, present study aimed assess effects of doses application times a biostim...

Sainpaulias are among the most popular flowering plants and there are so many variations in flower shape, size and color. Aqueous solutions of 0 M to 10 M concentrations of salicylic acid (SA) were foliar-applied on two African violet cultivars to evaluate the influence of different rates of SA on growth and flowering of plants. The solutions were applied to leaves of plants 14, 21, 28 and 35 d...

this experiment was conducted to study the effect of nozzle types and the time of herbicide incorporation in soil on weed control, using split plot design by randomized block design. the main plots were soil and herbicide mixing time and the subplots were nozzle types with three replications. this study was performed in karaj station of seed and plant improvement institute, located 25 km west o...

The potential of entomopathogenic nematodes in suppressing T. squalida population on cauliflower from transplanting to harvest was evaluated. Significant reductions in plant infestation percentage and population density (/m) were recorded throughout the plantation seasons, 2011 and 2012 before and after spraying the plants. The percent reduction in numbers/m was the highest in March for the tre...

proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...
