Abstract:
The field experiments were carried out at Horticulture Research Farm-I, Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.) during Rabi season of 2018-19 and 2019-20 to study the combined effect of varieties and spacing on growth, yield and quality of Knolkhol (Brassica oleracea var. gongylodes L.). The treatments were designed in a factorial randomized design with three replications, four varieties: V₁ (Pusa Virat), V₂ (White Vienna), V₃ (Early White Vienna) and V₄ (Palam Tender Knob) with four spacings: S₁ (30 x 30 cm²), S₂ (45 x 30 cm²), S₃ (45 x 45 cm²) and S₄ (60 x 45 cm²) were evaluated. The White Vienna with spacing 60 x 45 cm² showed maximum plant height (31.92 cm), number of leaves per plant (19.94), length of leaf (25.75 cm), width of leaf (27.63 cm) and plant spread (31.94 cm), knob weight per plant (238.25 g), diameter of knob (6.36 cm) and volume of knob (119.52 cc). White Vienna with spacing 30 x 30 cm² exhibited that the maximum yield per plot (7.07 kg) and yield (218.06 q ha^-1). The maximum TSS (3.90 ⁰Brix) was observed in Early White Vienna with spacing 45 x 45 cm², maximum vitamin C (39.08 mg/100g) was noticed in Early White Vienna with spacing 30 x 30 cm²) in Knolkhol.
