AbstractAn experiment was carried out at the field of Agriculture college/ Abu-Ghraib during fall season of 2006 to study the effect of number of sprays with Foliar nutrient fertilizer (Scotts) on growth and production of potato Cv. Desiree in Soil (pH = 7.5) and (Ec = 4.2). Scotts foliar fertilizer (Scott Company product) contains 10% N, 15% P2O5, 31% K2O, 0.1% MgO 0.1 and amount of chelated B, Cu, Mg, Zn and Fe at the rate of 2 ml/ L of water, plants were sprayed to drip point with either distilled water (30 days), or with nutrient solution, once (45 days), twice (45 and 60 days), or three times (45, 60 and 75 days) after planting plus control. Randomize Complete Block Design was adapted with three replicates. Plant height and number of branches/ plant increased when sprayed three times to 49cm and 13.67 branch/plant respectively, All treatment increased vegetative growth dry weight to 68, 64 and 61.7 g/ plant when sprayed three times, twice, once respectively. Dry weight percentage, tuber weight and plant yield increased when sprayed three times at 26.67%, 93.7 g/ tuber and 883.3g/ plant.
