Effect of sprayed Soluble different levels of iron chelate Nano fertilizer on nutrient uptake efficiency in two varieties of spinach (Varamin88 And Virofly)

ABSTRACT: Nano fertilizer with rapid absorption and optimized delivery of nutrients to the plant is new compounds to replace conventional fertilizer. To evaluate the effect of Nano fertilizer , a factorial experiment was preformed In a randomized complete block design with two cultivars (Varamin, Virofly) and chelated iron Nano-spray levels (0, 2 and 4 per thousand) with three replications on Research Farm of Sodoor Ehra Shargh co during crop year 2011. Our results indicate that sodium and nitrate accumulation in leaf were under the influence of Cultivars, so the nitrate concentration was less for Varamin Figure and sodium concentration was lower in Virofly Figure . Also Application of fertilizer was significant impact On all traits statistically. Application of Nano-chelate levels Increased accumulation of iron, potassium and decreased Accumulation of sodium, nitrate and Nitro in spinach leaves. Interaction Varieties and fertilizer on the ratio of sodium to potassium in the leaves Also had a positive impact so that its application of fertilizer leads to a reduction in the number of Virofly that were compared.
