الملخص EN

A field experiment was carried out in the fields of the A1 Bandar station of the Faculty of Agriculture - University of Muthanna during the sunnier season 2015 to study the effect of plant density and potassium fertilizers in traits of growth and yield of Peanut (Arachis hypogaea L), the experiment carried out using in RCBD design with three replication by Arrangement Split Pbt , the main plots were occupied of four treatments (83000-52500- 37000-29500 plant hectare'1), while potassium fertilizer occupied in three treatments (0-2- 4 g KiO litter'1) secondary panek.

the results showed that plant density (83000 plant hectare'1) gave the highest values of plant height (53.10 cm) and yield of pods (4007.3 kg / h) and seed yield (2215.3 kg hectare'1).

The plant density (52500 plant hectare'1) was significantly higher in the No.

of branches / plant (16.21 branch plant'1), dry weight of plant (108.53 g plant'1), seed weight plant'1 (35.44 g plant'1), and 100 seed weight (66.35 g), (4 g K2O litter'1) showed a "significant" effect on the rest of the treatments, giving the highest (50.94 cm).

No.

of branches (15.24 branches plant'1) and the highest dry weight (107.13 g plant'1), the highest weight of 100 seeds (64.42 g) and the highest average yield of seeds (3223.25 kg .

hectare'1).

The conciliation of (83000 x 4 g K2O litter'1) gave the highest plant (53.4 cm) and seed yield (2538 kg hectare'1) while (52500 x 4 g KiO iter1) gave No.

of branches plant-1 (16.43 branch plant'1) but there are no significant ini 00 seed weight, yield of pods and dry weight of plant.
