A field trial was carried out in 2010 to investigate the effect of foliar application of seaweed extract “Primo” as an organic biostimulant on potato cv. ‘Sante’. Foliar application of seaweed extract was carried out at different growth stages of the crop (i.e. 30 days; 45 days; 60 days; 30 and 45 days; 30 and 60 days; 45 and 60 days; 30, 45 and 60 days after sowing). Control plants were sprayed with water without seaweed extract. A significant improvement in growth, yield and tuber quality of potato was observed where treatment was applied. The highest tuber yield was recorded with applications of seaweed extract at 30 + 60 days interval after planting. The treatment also improved nitrogen, total soluble solids and protein contents of the potato tubers. The results of the study concluded a positive response of potato plant growth and yield to the foliar application of seaweed extract.
