Field experiment was conducted at the agricultural experimental farm of agronomy department – Collage of Agriculture – University Of Anbar, during the two winter seasons of 2015/2016 and 2016/2017, to study the effect of amino acids with different concentrations on the yield and yield components of three wheat varieties. The experiment was performed in split - split plot using RCBD in three replicates, where amino acids plots (Tryptophane, Arginine and Tyrosine) were assigned to the main plots, subplots were occupied by acid’s concentrations (0, 100, and 200 ml L-1 each), while the varieties (Alrashed, Tamoz2 and Abu Ghraib3) occupied the sub-subplots. The Obtained results showed that the amino acids significantly affected the studied traits, where applying Tryptophan increased spike length in the 1st season and increased the weight of 1000 grain in 2nd season. Spraying Tyrosine gave the highest average of spikes number per m-2 in the 1st season, grains number per spike 47.33 and 49.94 grain per spike for the both seasons and therefore increased the grain yield 5.92 and 6.83 t.ha-1. Whereas amino acids didn’t show any significant effect on the harvest index. Amino acids concentrations had a significant impact on traits such as spike length, grains per spike, weight of 1000 grain and grain yield. Concentration of 200 mg L-1 gave highest grain yield value reached 6.27 and 7.16 t ha-1 for both seasons respectively, while had no significant effect on the harvest index. Used varieties differed significantly for studied traits in both seasons, Alrashed variety was superior in traits like spike length, number of grain per spike (47.86 and 49.19), 1000 grain weight 34.12 and 35.49 gm, grain yield 6.32 and 7.09 t ha-1 and the harvest index for both seasons respectively. However Abu Ghraib3 variety was superior for spikes per square meter 507.0 and 523.9 spike.m-2.

A field experiment was carried out in clay loam soil during spring and autumn seasons , 2008 to study three levels of K fertilizer ( 0 , 70 and 140 Kg / ha ) and three distances between raws ( 50 , 60 and 70 cm ) on growth and yield of two sorghum cultivars (Ankath and Rabih). A split–split plots design was used according to R.C.B.D. with three replicates. Cultivars was assigned as main plots and plant distance as sup plots , while the sub–sub plots were K fertilizer levels.
Results showed a significant difference between the two cultivars in a day from sowing to 50% of flowering , leaf area , leaf area index, 500 grains weight, grains no. head-1 and harvest index . increased rows distance from 50 to 70 cm caused
earliness of flowering , increased leaf area at in monsoon, leaf K% , grain no. head-1 , 500 grain weight and harvest index (24.56 , 30. 28%) for each season. 50 cm was superior in leaf area index , biological yield and grain yield(7.19 , 10.52 t.ha-1) for each season respectively. Increase of potassium level lead to be earlier flowering and significant increase in all agronomic and yield traits . The potassium level of 140 kg.ha-1 gave the highest grain yield and harvest index of 6.88 and 10.32 t.ha-1 , and 24.47 and 31.11%, for each season respectively. It could be
concluded that grain yield could be increased by using the distance that applied in Iraqi agronomy of 20 X 70 cm, where as, the increase about it 25.92 and30.68% , for each season respectively. Land, production, water management and reduced weeds growth , also could be used , if this distance properly applied.
