This study was conducted to investigate the effect of bacterial bio-fertilization A. chroococcum and P. putide and four levels of compost (0, 1, 2, 3) tons.h-1 on the leaves content of N.P.K elements. The experiment was carried out in one of the greenhouses of the College of Agriculture - University of Al-Qadisiyah during fall season 2018-2019. It designed in accordance with the Randomized Complete Block Design (RCBD) with three replicates in sandy loam soil. The means of treatments were compared with the least significant difference (LSD) at (5)% probability level. The results present that the treatments of A. chroococcum, P. putide and compost at (3) tons.kg-1 significantly increases the leaves content of K.P.K compared to all other treatments in the flowering stage (4.970, 0.5000, and 4.930) mg.kg-1, respectively. This treatment was followed by the effect of the treatment of A. chroococcum and compost at (3) tons.kg-1, which increases the values of all traits except the leaf content of (P). Bio-fertilizer with P. putide + A. chroococcum significantly increases the leaves' content of P.

Field experiment is conducted at the college of Agriculture - University of Diyala to study the effect of two factors : organic fertilizer and nitrogen fertilizer on the grow and productivity of wheat that grow in salt soil (10 dS m-1), two levels of organic fertilizer were used (2 and 4 t h-1 ) and three levels of nitrogen were used (0, 50 and 100 kg h-1). Result show that both of organic fertilizer and nitrogen levels have significantly effect on agronomy and productivity attributes of wheat, interaction between the second level of organic fertilizer and the third level of nitrogen is the best result in plant height 75.9 cm, tillers 7.1, flag leaf area 31.4 cm2, dry weight of shoot 365 g, spike weight 3.36 g, number of spikes/ m2 203, number of seeds in the spike 36.9 and the weight of 100 seeds 11.22 g are significantly differences in other treatments.

An experiment has been conducted in Altalia'a City / Babylon on Paprika Capsicum annunm, California wander cultivar , during the season 2012 under open field in loamy soil . This study includes (9) treatments which are resulted form three levels of humic acid ( 0 , 30 , 40 )g/m2 with 3 dates of added at (15 , 30, 45 days ) from transplanting and their effect on vegetative and fruit growth . The experiment adopts the Split Plot Design (SPD) within RCBD with three replicates and the means are compared to Duncan's Multiple Range Test at the probability level of 0.05.
Results show superiority of all concentrations of humic acid treatments significantly as compared with control treatment in all vegetative growth and fruiting properties and the interaction of is C×T significantly affected the above parameters to control treatment for the four pickings ( 2 , 4 , 6 , 8 ) , for recipes studied .
The treatment dates added have more than the first date on the other two date for prescription rate of plant height (cm) of the four pickings and the results are ( 115.3 , 120.4 , 130.7 , 145.4 ) cm , respectively .While the number of leaves / plant and the area cm2 / plant the second and the third date is superior on the first date , while the number of fruits / plant for the third date has significant above the picking (4, 6 , 8) and the results are ( 20.37 , 19.84 , 13.70 ), fruit / plant , respectively .
Whereas fruit weight in first and second dates are superior. Either recipe yield plant kg / plant outweigh the second date of the another dates and for the four pickings ( 2, 4, 6, 8 ) are ( 0.719 , 2.058 , 2.842 , 3.490 ) kg / plant , respectively
