to evaluate the effect of on-farm seed priming and methods of zinc sulfate application on seed emergence properties, yield and yield components of two corn cultivars, an experiment was conducted as factorial in randomized complete block design with three replications during 2012 at research farm of bu-ali sina university, hamedan. first factor was methods of zinc sulfate application containing ...

in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...

background and objectives: seedy watermelon (citrullus lanatus) is a crop that is planted in as a second crop after winter crops some parts of country. this crop is more attended by farmers due to the short time between planting and maturity, low production costs and greater profitability rather than other spring crops. in order to evaluate the interaction effects between weeds and seed priming...

to study the effect of vermicompost and urea and iron sulfate fertilizers on the growth characteristics and yield of sunflower seed (helianthus annuus l.) an pediment was conducted in darreh gaz located in khorasan razavi province in 2012. factorial experiment in a randomized complete block design with three factors and three repetition. in this experiment three levels of urea (50; 150 and 250 ...

in this research, the effect of foliar spraying times and different levels of farmax® nano fertilizer on morphological characteristic and dry and fresh flower yield, essential oil and chamazulene percentage of chamomile (matricaria recutita l.) cv. bodegold was studied. the experiment was factorial in the bacic of randomized complete blocked design (rcbd) with eight treatment and four replicati...

the study was carried out to examine the effects of urban sewage and nitrogen fertilizer levels on yield quantity and quality forage of sweet corn was evaluated in yasouj at 2009. the main experimental factor consisted of 5 irrigation levels including: common irrigation water without sewage effluent until the end of plant growth (i1), the first half of plant growth period with sewage effluent a...

water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...
