DOI: 10.22161/ijeab.75.4

Abstract:
The effect of NF on sunflower cultivars of Flamy (FL) and Manon (MA) were tested during planting at three NF of 175, 200 and 250 kg.N.ha-1. The experiments were conducted in a factorial experiment under complete randomized design with three replications. The results showed that the MA cultivar was significantly better than the FL in all studied conditions. The soil properties SBD, TSP, RL, RDFW, PDFW, SD, Sl, PVI and GY were; 1.29mg.cm-3 ,1.30 mg.cm-3,1.33 mg.cm-3, 51.32%, 50.94%, 49.81% ,24.115 cm , 161.419 g, 184.624 g, 38.01 mm, 22.58mm , 80.39 cm and 5.311 t.ha-1, respectively. The NF of 250 kgN.ha-1 was significantly superior to the levels of 175 and 200 kg N.ha-1 in all studied conditions.
