Abstract

This study was conducted in vegetable farm, Department of Horticulture, College of Agriculture, University of Baghdad for fall season 2008 and spring season 2009. To investigated the influences different applied to the soil of nitrogen fertilizer and foliar sprays (Terra-Sorb) on growth yield some potato cultivars. RCBD design for split-plot was adapted, the cultivars Binella and Riviera for fall season and Desiree and Riviera for spring season were main-plot.

While the seven levels of N fertilizer with control treatment in sub-plot as follows: (T0) as control (without fertilizer) and (200 , 400 , 600 Kg N/ha) and ((200 , 400 , 600 Kg N/ha + 3ml/L terra-sorb) and only (3ml/L terra-sorb).
The results shown the superior of Binella and Desiree cultivars in vegetative and yield characters, compare with Riviera cultivar. While the fertilizer treatments significantly influenced the vegetative characters, the highest level of( 600 Kg N/ha + terra-sorb) significantly gave the highest emergence percentage (92.12 and 100.0%), numbers of main (4.15 and 4.70 stem/plant), the highest of plant (68.41 and 77.55 cm), leaf area (7793.4 and 10534.4cm2), leaf area index (4.15 and 5.61), the percentage of chlorophyll in leaf (41.83 and 45.83 SPAD), the dry weight of vegetative parts (63.13 and 66.78 g/plant) for fall and spring season respectively. While (400 kg N/ha + terra-sorb) significant influenced the number of tubers (9.50 and 10.78 tuber/plan), plant yield (1033.3 and 1034.3g/plant), total yield (49.11and 53.52tan/ha) for both season respectively.
