Abstract
A field experiment was carried out in the province of Muthanna / station Al Bandar during the growing season in 2015 to study humic acid and potassium on growth and yield of the wheat crop, the experiment carried out using a Split Plot Design with three replications the main plots were occupied of three treatments of humic acid is (0-2-4) ml liter -1, while potassium fertilizer occupied in three treatments (0-80-160) kg. h-1 in the form of potassium sulfate (52% K2O) secondary plots wheat class (Abu Ghraib), the results showed superiority of the treatment of 4 ml liter -1 morally in plant height 107.3 cm, and the number of tillers / plant 7.3 Area flag leaf 33.55 cm 2 while the treatment of the control as little as possible plant height, reaching 96.22 cm, and the number of tillers / plant where it reached 4.5 Area flag leaf, which amounted to 26.11 cm 2, and for yield and its components, the results showed that there were significant differences between acid treatments humic in The traits quotient and its components except 1000 grains, where he excelled treatment of 4 ml liter -1 morally in spike length 13.88 cm, and a number of spikes / m2 317.7 spike and number of grains in the spike 65.44 grains and yield grain 4.734 tons / h, while the treatment of the control as little as possible spike length 11.65 cm, and the number of spikes / m2 299.7 spike and number of grains in the spike of 57.2 grains and yield grain 3.504 t / ha higher than the treatment of 160 kg / h was significant for plant height where it reached 105 cm, and the number of tillers / plant where it reached 6.9 Area flag leaf, which amounted to 31.7 cm2 while the treatment control the least we can plant height, reaching 100.2 cm, and the number of tillers / plant reaching 5 tillers, Area flag leaf, 25.11 cm2, the results showed that there were significant differences between potassium treatments in the qualities of yield and its components except number of grains / spike, where he excelled treatment of 160 kg / h was significant spike length 13.88 cm, and a number of spikes / m2 310.6 spike and 1000 grains weight 41.76 g and yield grain 4.55 ton / h, while the treatment of the control as little as possible spike length 11.65 cm, and a number of spikes / m 2280 spike and 1000 grains weight 31 grams and yield cereals 3.66 ton / h, and the results showed that the overlap between the humic acid treatments and fertilizer potassium has achieved the best results in the treatment of (160 x 4) in the recipe plant height (107.1 cm) and number of spikes / m 2 (309 spike ) , number of grains in the spike (73.3 tablets) and yield grain per hectare (4.7 tons / h), while it was not the overlap between the treatments were significant differences in the qualities of tillers and leaf area and spike length and weight of 1000 grains.
