Abstract
The field experiment was conducted during two subsequent years, i.e., 2017-18 and 2018-19 at the Department of Horticulture, Hisar with aim to study the effect of organic manures and Azotobacter on quality and leaf nutrient status of strawberry cv. Winter Dawn under hi-tech greenhouse conditions of Haryana. In this experiment, organic manures in combination with biofertilizers comprised of nine treatments, viz., T1: Sand: FYM (3:1), T2: Sand: FYM (2:1), T3: Sand: Vermicompost (3:1), T4: Sand: Vermicompost (2:1), T5: Sand: FYM (3:1) + Azotobacter, T6: Sand: FYM (2:1) + Azotobacter, T7: Sand: Vermicompost (3:1) + Azotobacter. T8: Sand: Vermicompost (2:1) + Azotobacter and T9: Control (Sand); were tested as potting media in complete randomized block design. Maximum TSS, ascorbic acid, anthocyanin content and minimum acidity content and leaf with maximum N, P and K content were observed under sand: vermicompost (2:1) + Azotobacter in comparison to the other treatments. The results of this experiment revealed that, the combination of sand: vermicompost (2:1) with Azotobacter showed significant influence on leaf nutrient content of strawberry and produced better results with respect to quality of strawberry fruits.
