Abstract

A field experiment was conducted at Al- Qurna (Al-Sharash) district, during the 2017 autumn season to investigate the effects of foliar Nano-fertilizer application rates (0, 6, 12 and 18 g L -1), which contains 11 nutrients (5% nitrogen, 3% phosphorus, 3% potassium, 6% calcium, 6% magnesium, 8% zinc, 4.5% iron, 0.7% manganese, 0.1% boron, 0.65% copper, 65% molybdenum) on growth and yield of three genotypes of corn (Cadiz, Sagunto, and Abcaro). Increasing Nano fertilizer rate to 18 g.l-1 highly increased number of days from planting to 50% male and female flowering (61.25 and 65.17 days), plant height (189.38 cm), leaf area (4629.96 cm2), number of grains per ear (561.28 grain ear-1), weight of 300 grains (103.43 g) and grain yield (6.79 t ha-1). Sagunto genotype gave the highest number of grains per ear (574.23 grain), and grain yield (6.16 t ha-1). Sagunto treated with 18 g.l-1 was superior treatment in terms of plant height (192.25 cm), leaf area (5262.25 cm2), and grain yield (7,99 t ha-1).
