Abstract

A pot trial study was conducted during agricultural season for 2016-2017 at College of Agriculture - University of Anbar-Abu Ghraib, alternate location. To study of effect method addition of humic acid and level of fertilizer recommendation in growth and yield of wheat Triticum ssp. Ibaa type -99. The experiment was conducted with two factors the first factor was four levels of the fertilizer recommendation it's: F0 without adding, F1 50%, F2 75% and F3 100%, from fertilizer recommendation. The second factor was ways to add the humic acid in four ways to add H0 Without adding, H1 add spray, H2 add ground and H3 add (spray + ground). The study was conducted with three replicates with using with design of randomized complete block design (RCBD).
The result of the study showed that The highest yield of wheat grains in the fertilizer recommendation 50% and the ad The addition of levels of the fertilizer recommendation led to increase the concentration N, P and K in wheat seeds as a percentage addition of humic acid spray + ground, it was 30.40 gm.pot-1 and the addition of humic acid lead to increased concentration this element in wheat seeds.
