Effect of foliar application of sida compound fertilizer on growth, yield, and fruit chemical composition of ‘early superior’ grapevine

This experiment aimed at studying the effect of Sida Compound fertilizer containing seaweed extract, natural fertilizers, growth promoters and micronutrients in chelated form on growth, yield and berry quality of table grape ‘Early Superior’. Foliar application of Sida Compound at concentration 0.05 to 0.20%, three times in a season increased shoot length, leaf area and content of N, P and K in the leaves as well as total soluble solids and total sugar contents in fruits. Yield of fruits increased by 29 and 14%, depending on the season.
