This research was carried out at the Technical Institute of Wasit governorate in Iraq in the agricultural area of the Hay district for evaluate the effect of the zero tillage farming system and compare it with traditional Tillage farming with applied four rates of urea 46% fertilizer (zero, 30, 40, 50 kg / d and three rates of superphosphate 20% fertilizer (zero, 30, 40 kg / d.) on some vegetative growth and yield traits for wheat Iba-99 variety in agricultural season 2016- 2017. Where planted seeds at rate 40 kg / donum equal 240 g /plot, by using RCBD design with three replicates. The results showed an increase in the zero tillage culture than traditional culture in the level 0.05,but did not differ significantly from the traditional culture at 0.01probability in all vegetative and yield traits. The values were superior in the zero tillage culture as follows: Plant length 81.3cm, Number of tillers 7 /plant, Spike length 11.5 cm, Number of spikes302/m2, Number of grains 51/spike ,Weight of a thousand grains 43, 2 g and total grains yield 3,680 tons / hectare while values of traditional agriculture were ; Plant length 81.2cm, Number of tillers 6/ plant, spike length 11.4 cm, Number of spikes 301/m2 , Number of grains 50/spike, Weight of 1000 grain 42.1 g and total grains yield 3,520 t / h. showed the urea fertilizer superior at a rate of 50 kg / d in all of traits; Plant length 92.3cm, Number of tillers 9 /plant, Spike length 11.9 cm, Number of spikes 307/m2, Number of grains 57/spike, Weight of 1000 grain 46,4 g and total grains yield 4,160 tons / h, showed the superphosphate fertilizer superior at a rate 40 kg/h in all traits ; Plant length 88.6cm, Number of tillers 8 /plant, length of spike 11.6 cm Number of spikes 304 / m2, Number of grains 55/ spike, Weight of 1000 grain 45.2 gm and total grains yield 4,060 t / h. The interaction between the zero tillage culture system and both levels of fertilizer (Nitrogen 50, Phosphate 40 kg / d) showed significant superiority in probability level 0,05 and not differs in probability level 0,01 in all traits, where total grain yield reached 4,269 and 4,165 ton/ h respectively. Conclusion that both N,P fertilizers kinds were better than the interaction between traditional farming and both 2 kinds of fertilizer in all traits of plant. Evaluates the zero tillage system farming better than traditional farming due to improving of all traits of plant in addition of its ecological, economical importance in achievement of sustainable agricultural development.
