| Abstract | The effect of foliar application of seaweed extracts Bio-algeen S90 (Ascophyllun nodosum) and Kelpak SL (Ecklonia maxina) and humic and fulvic acids from leonardite HumiPlant on plant growth and marketable tuber yield of early potato crop was investigated. The application of seaweed extracts resulted in a faster rate of plant growth. Bio-algeen S90 affected potato growth more than Kelpak SL. The plants grew taller and produced a greater above-ground biomass. With the use of HumiPlant, stems were shorter but had a similar weight to plants in the cultivation without biostimulant. Biostimulants caused enlargement of the assimilation leaf area, but had no effect on the weight of leaves, leaf weight ratio (LWR) or leaf area ratio (LAR). The yield-increasing effect of biostimulants depended on hydrothermal conditions during potato growth. Seaweed extracts produced better results in a warm and a very wet growing season, whereas humic and fulvic acids produced better results in a cool growing season with drought during the tuber growth period. |
