Abstract
This studies was conducted in the experimental field, Department of Horticulture, College of Agriculture, University of Baghdad , Abu- Ghraib, during the fall and Spring seasons 2006-2007 using Desiree cultivar potato seeds, To investigate effect of manures and mulching on the concentrations of N,P,K and growth of potato plant. The first factor inculded either the using of black polyethylene sheet (M1)or without it (M0). The second factor included using of 6 types of organic manure; the first was without organic manure( control T0), The second was chemical fertilizer(T1), the third was sheep manure (T2), The forth was local peatmoss(T3), the fifth was dry Pow humus(T4) and the sixth was liquid Humic acid, In split - plot design with three replicates. Results showed that concentrations N,P and K in leaves were significanty increased in mulching potato plants wth black polyethylene (M1) to reached ( 13.4, 8.0, 14.5 g.kg-1) and (20.5, 12.0, 34.4 g.kg-1) for fall and spring season respectively as compared with the control (M0). This has positively reverse on morphological characteristics (numbers of stems , height of plants, leaves area) to ( M1 ) compared with (M0) and Treating potato plants with chemical fertilizer (T1) Sheep manure (T2) significantly increased the concentrations of N,P,K in leaves in fall season to reached (14.6, 9.3, 15.5 g.kg-1) and (13.4, 8.7, 15.1 g.kg-1) respectively. As compared with the control (T0) to reached (9.4, 5.5, 12.0 g.kg-1 ) while in Spring season to reached (2.19,1.10, 3.61% and (19.9,10.8, 34.4 g.kg-1)respectively As compared with the control (T0) to reached (16.1,7.1, 27.9 g.kg-1). Results showed significant increases occurred in height of plant and everage leaves area in the interaction between mulching and sheep manure (M1T2) to reached (45.11 cm and 6678.90 cm 2) and (67.88 cm and 10168 cm2) for fall and spring season respectively as compared with the control (M0T0) to reached (39.55 cm and 4621.10 cm2) and 41.88cm and 5023.00 cm2) for both seasons respectively.
