Impact of Bio-fertilizer on vegetative growth quality of cauliflower (Brassica oleracea L. Var.botrytis) CV. Pusa Snow Ball K-1

The present study examined the effect of bio-fertilizers on growth of cauliflower (Brassica oleracea L. var. botrytis) cv. Pusa Snowball K-1. The study was conducted during Rabi 2015–2016 at Horticulture Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow, Uttar Pradesh. The treatment combination of bio-fertilizers was studied with different doses as T1 (Control), T2 (FYM, 20 t/ha.), T2 (Vermicompost, 5 t/ha.), T4 (Azotobacter, 2 kg/ha.), T5 (PSB, 2 kg/ha.), T6 (Neem Cake, 10 t/ha.), T7 (FYM + Vermicompost, 5 t/ha.), T8 (FYM + Azotobacter), T9 (FYM + PSB), T10 (FYM + Neem Cake), T11 (FYM + Vermicompost + Azotobacter) and T12 (FYM + Vermicompost + Azotobacter + PSB). Cauliflower growth including Plant height (cm), Number of leaves per plant, Length of leaves (cm), Width of plant (cm), Spread of plant (cm) and Stem diameter (cm) were measured at 30, 60 and 90 days after transplanting respectively. Significant differences were observed for all the above mentioned parameters across the biofertilizer doses in cauliflower under Lucknow conditions.
