The study was carried out to investigate the effect of variety and NPKZnB fertilizers on growth and yield of Kohlrabi using two varieties viz, Early 005 and, Quick Star, and five different levels on NPKZnB fertilizers viz, F0: Control (N0P0K0Zn0B0), F1: 50 kg N ha + 12.9 kg P ha + 62.25 kg K ha + 2 kg Zn ha + 1 kg B ha, F2: 75 kg N ha + 25.8 kg P ha + 124.5 kg K ha + 4 kg Zn ha + 2 kg B ha, F3: 100 kg N ha + 38.7 kg P ha + 186.75 kg K ha + 6 kg Zn ha + 3 kg B ha and F4: 125 kg N ha + 51.6 kg P ha + 249 kg K ha + 8 kg Zn ha + 4 kg B ha. The two-factor experiment was laid out in RCBD with three replications. Different variety and NPKZnB fertilizers showed highly significant influence on almost all the studied parameters. In case of variety, the taller plant height (28.47 cm), fresh weight of knob and root (407.33 and 3.32 g plant), the highest gross (22.47 kg plot) and marketable (19.55 kg plot or 67.89 t ha) yield were obtained from Quick Star while the dwarf plant (24.60 cm), fresh weight of knob and root (378.67 and 2.51 g plant), the lower gross (21.67 kg plot) and marketable (18.18 kg plot or 63.04 t ha) yield were found from Early 005. In case of NPKZnB fertilizers, the tallest plant (28.63 cm), fresh weight of knob and root (467.50 and 3.23 g plant), the highest gross (25.34 kg plot) and marketable (22.44 kg plot or 77.92 t ha) yield were obtained from F4: 125 kg N ha + 51.6 kg P ha + 249 kg K ha + 8 kg Zn ha + 4 kg B ha while the dwarf plant (24.00 cm), fresh weight of knob and root (279.20 and 2.57 g plant), the lowest gross (16.40 kg plot) and marketable (13.40 kg plot or 46.36 t ha) yield were found from F0: control (no fertilizers). In case of combined effect, the tallest plant (31.20 cm), fresh weight of knob and root (478.30 and 3.80 g plant), the highest gross (25.41 kg plot) and marketable (22.96 kg plot or 79.72 t ha) yield were obtained from Quick Star grown under 125 kg N ha + 51.6 kg P ha + 249 kg K ha + 8 kg Zn ha + 4 kg B ha, whereas the dwarf plant (22.93 cm), fresh weight of knob and root 263.30 and 2.30 g plant ), the lowest gross (15.52 kg plot) and marketable (12.64 kg plot or 43.55 t ha) yield were found from variety Early 005 grown with F0: control (no fertilizers). These findings concluded that variety Quick Star with 125 kg N ha –1 + 51.6 kg P ha + 249 kg K ha + 8 kg Zn ha + 4 kg B ha was the best successful combination for the highest production of Kohlrabi.
