| Abstract | ||
| Field study was conducted in loamy soil through spring loop 2010 agriculture season , to study the effect of nitrogen and organic fertilization in addition to their overlap on the growth and potato yield / Desere variety. The study include two levels of nitrogen fertilizer ( Urea 46% N ) which was 200 and 400 Kg N/ h , and two levels of organic fertilizer ( ferment cow waste ) which was 2 and 4 ton/ hectare . RCBD with three blocks were used , and LSD test used to differences between average values of plant characteristics .The result shows that the treatments of mineral fertilizer mixed with organic fertilizer (200 kg /h +2 ton/h ) , (400 kg /h +2ton /h ) , (400kg /h +2 ton /h ) , and (400 kg /h + 4 ton / h ) appear high significant differences comparing with another treatment , causing increasing in plant heigh ( cm ) , number of stems , wet and dry matter of plant (gm) , number of tubers , weight of tubers , in addition to percent of Nitrogen, phosphorus and potassium uptake by plant leaves . | ||
