Productivity of some sunflower hybrids by modern systems of irrigation and fertilization under newly reclaimed soil

Abstract: The experiments in this respect were conducted in 1997 and 1998 seasons in El-Ghorieb. Three experiments were carried out in each season representing the systems of irrigation, i.e. surface, sprinkler and drip systems in which every experiment was represented by one system of irrigation. Through each experiment four hybrids, i.e. Pioneer 6480, Vidoc, Phoebus and Bioseed were distributed in the main plots. The spaces within plants, i.e. 20 and 30 cm were in the sub-plots. The results obtained proved that drip irrigation favoured growth traits, yield & yield components, oil percentage, oil yield/feddan, seed moisture percentage, water consumptive use (CU) and water use efficiency (WUE). All the previous traits were affected significantly among the hybrids studied. Spacing of 20 cm within the row produced higher seed yield/feddan. Here the recommended fertigation rate of 30 + 15 + 12.5 kg/feddan for N, P2O5 and K2O, respectively favoured the traits studied
