Abstract

Bio stimulants like amino acids and filmic acids, aid in the penetration of nutrients into the plant system and increase the antioxidant enzyme activity which provides stress tolerance to plant and enhances crop performance. To evaluate the potential effectiveness of foliar application of Ambition- a biostimulant in apple, an experiment was conducted at Regional Horticultural Research & Training Station, Sharbo (Kinnaur, Himachal Pradesh), to determine the response of Ambition- a biostimulant on yield and quality of apple cv.
