safflower (carthamus tinctorius l.) is one of the oilseed crops adaption on a wide range circumstance of iran edaphic, which deficiency of micronutrients cause in its quality and quantity yield. to assign the effect of amount and utility period of micronutrients fertilizer on grain yield, yield components and characters of oil quality of safflower var mexi141 an experiment by factorial base ran...

Field trials were used to investigate the phytotoxicity of foliar sprays of 2,4-D amine to sugarcane. Yield losses of variety NCo 376 resulted from band sprays when 3,3 kg ae/ha was sprayed onto plant or ratoon cane which had unfurled three or more leaves per shoot. The greater the foliar development of the crop at the time of spraying, the greater was the resulting crop loss. At similar stages...

This study was conducted to compare the effects of foliar spray and rhizosphere irrigation with purple phototrophic bacteria (PPB) on growth and stevioside (ST) yield of Stevia. rebaudiana. The S. rebaudiana plants were treated by foliar spray, rhizosphere irrigation, and spray plus irrigation with PPB for 10 days, respectively. All treatments enhanced growth of S. rebaudiana, and the foliar me...

in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...

In Poland nearly 40% of land under agricultural use is characterised by a progressing deficit of copper available to plants. Inventory studies revealed that 25% of rapeseed plantations are undernourished with this component. The objective of the study was to estimate the yield-forming effects of foliar and soil fertilisation of rapeseed with copper, to identify the optimum dose of Cu for the cr...
