Nutritional assessment of micronutrients on quantitative and qualitative characteristics of amaranth seed production (Koniz)

The aim of this study was to determine the best amount and timing of fertilizer micro zinc, iron and manganese on yield and seed quality is produced by Amaranth. Field experiments for combined analysis factorial randomized complete block design with three replications in two years (2014-2015) were conducted at the research station of Islamic Azad University of Malekan. The factors included micro fertilizers (iron, zinc and manganese), four different concentrations (7, 5, 3 per thousand and zero or non-use) and three stages (vegetative, reproductive and vegetative + reproductive + grain filling) was considered. The results showed that the highest number of seeds and grain yield (respectively 4460 number 17/99 gr/crop) were obtained using an iron concentration of 7 per thousand. Grain yield increase of 29/24 percent than control. The highest protein content was obtained by foliar application 7 per thousand micronutrients. Maximum panicle was 3/042 number by foliar application 7 per thousand on three phases. Maximum chlorophyll content (32/1 CCI) by application iron with 5 per thousand concentration. The maximum oil grain and oil yield, respectively (33/59%) and (6/083 gr/crop) if foliar application with zinc 7 per thousand concentrations were obtained. Based on the results of traits for fertilizer micro traits can be stated that maximum of the grain, grain yield, oil content and oil yield was achieved by foliar application 7 per thousand element and 7 per thousand micro elements concentration of protein content increased.
