| ABSTRACT This study was carried out in a private farm at Haway Rezyana, 15 Km north-east of Mosul-Iraq, during spring season 2009. The aim of this research was to study the effect of two seaweed extracts (Alga 600 and Solauamine) and three methods of application (foliar spray, adding to the soil and foliar spray with adding to the soil) on growth and yield of two potato varieties (Latona and Desiree). A split plot within randomized complete block design with Duncan's multiple rang test at 0.05 were applied for all research data. The obtained results could be summarized as following: Desiree variety was significantly superior in average plant length, plant leaf area, percentage of chlorophyll pigment, root dry weight, average tuber weight, yield of plant, total yield, marketable yield and tuber firmness as compared with latona variety. While a significant increase recorded in mean stem number per plant, percentage of foliage dry weight and tuber specific gravity with latona variety comparing with Desiree variety.Application of Alga 600 treatments caused a significant increase in average plant length, tuber weight, plant yield total yield and marketable yield as compared with control treatment. Adding Alga 600 to the soil caused a significant increase in plant yield, total yield, and marketable yield, while application Alga 600 as a foliar spray resulted a significant increase only in average tuber weight as compared with control. Interaction treatments between verities and method of application caused additional increase most vegetative and yield characteristics. Interaction treatments between Desiree variety with all methods of application caused a significant increase in most vegetative and yield quantity and quality characteristics as compared with the effect of interaction treatments between latona variety and application method of seaweed extracts, which caused a significant increase in both average stem number per plant and tuber specific gravity only. | ||
