Effect of inorganic fertilizers, Azotobacter and GA₃ on quality parameters of sprouting broccoli under subtropical condition of Garhwal Himalaya

The present study was accomplished on sprouting broccoli (Brassica oleracea L. var. italica) to investigate the effect of inorganic fertilizers, Azotobacter and GA₃ on growth and yield parameters of sprouting broccoli. The experiment was conducted in Randomized Block Design (RBD) and replicated 3 times with 16 treatments. The maximum total soluble solid (10.66 ⁰Brix) was recorded in treatment T₂ (NPK 75%), which was found to be significantly superior over other treatments. Whereas, the minimum total soluble solids (5.34 ⁰Brix) were found in treatment control T₁₆. The maximum vitamin C (100.58 mg/100g) was recorded in treatment T₆ (NPK (100%) + azotobacter followed by (94.60 mg/100g) in treatment NPK (100%) + GA₃ (50ppm) T₇, which was found to be significantly superior over other treatments and the minimum vitamin C (60.10 mg/100g) content was found in treatment control T₁₆.
