The present investigation was carried out during 2023-24 at Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh to study the effect of calcium chelate and carbonic powder on growth, yield and quality of Strawberry (Fragaria x ananassa Duch.) cv. Winter Dawn under agro-climatic conditions of Prayagraj. The experiment was laid out in RBD, replicated 3 times with 16 treatments with different combinations. The characters of growth, yield and quality characters are noted. Based on above characters it is concluded that treatment combination T­₁₅ (Calcium chelate (5g/L)+Carbonic powder (5g/L)+RDF(19:19:19) performed best in terms of plant height (cm) (33.74), plant spread (cm) (41.18), number of leaves per plant (44.01) , petiole length (cm) (14.96) , days to first flowering (40.18) , days to first fruiting (48.57), number of flower per plant (20.62), number of fruit per plant (16.30), fruit weight (gm) (40.78),fruit per plant (g) (664.77) , fruit yield t ha^-1 (26.59) , TSS ⁰brix (10.45), juice content (%) (94.58) and pH(3.17) of strawberry. Importance of conducting this experiment is defined that calcium chelate and carbonic powder improves the fruit size, fruit weight and firmness. So, the quality and shelf-life of a fruit also increases. It will help to export the fruits to other countries.
