| Abstract | ||
| A field experiment was carried out in one of the fields of plot 158 district 41 Husseiniya , township of Taliaa, Babylon Governorate, to study fertilizer use efficiency of nano fertilizers micronutrients foliar application on Jerusalem artichoke (Helianthus tuberosus L.).The experiment included 17 treatments of spraying the nano-fertilizes micronutrients of nano iron 13% Fe ,nano zinc 20% Zn, nano copper 15% Cu and nano manganese 18% Mn, single spray, dual, triple and quadruple combinations, as well as a quadratic combination of a traditional source as well as the treatment of water-only control. In nutrients content in arial parts and tubers, nutrients uptake, total uptake ,FUE,MNUE. RCBD design with three replicates, and the solutions were sprayed early in the morning after 60 days of planting and at 25, 50, 75 and 100 g fertilizer 100 L-1 Water for to spray the first, second, third and fourth respectively, and according to the recommendation by 1 kg Naon fertilizers h-1, and another 400 liters of spray solution h-1. The results of the duncan test showed a probability level of 0.05 The superiority of the single spray treatments followed by the treatment of nano (Zn+Cu+Fe+Mn) in micronutrients content of arial parts and tubers of zinc, copper, iron, manganese and total uptake, While achieved the nutrient use efficiency of nano-zinc, nano-copper, nano-iron and nano-manganese (93.10, 85.00, 99.00 and 85.50%) sequentially. For individual spray treatments and (91.60, 81.30, 91.85, and 83.40%) sequentially for the treatment of nano spray common quartet (Zn + Cu + Fe + Mn). . | ||
