Abstract: The experiment was conducted during winter season of during 2016-17 and 2017-18 at the Horticulture farm of Udai Pratap, Autonomous College, Varanasi (U.P.), is situated in the South eastern part of Varanasi city was carried out during winter season. The experimental material used for the “Effect of NPK, Vermicompost and Spacing on growth and yield of Broccoli (Brassica oleracea L. var. italica)” The materials used, experimental procedures followed and techniques adopted during the course of experimentation were planted at a spacing of 45cm x 45cm and 45cm x 60cm per plot under open conditions. The experiment was laid out in RBD comprising of Sixteen treatments with three replication study F3 (180:80:80 NPK kg ha-1) and minimum in F1 (140:40:40 NPK kg ha 1) and at 45 and 60 DAP the minimum plant height was recorded with F4 (200:100:100 kg ha 1) and minimum with F1 (200:100:100 kg ha 1) and minimum with F1 (140:40:40 NPK kg ha 1) during both the years of study. In case of spacing S1 (45 x 45 cm) recorded maximum and minimum in S2 (45 x 60 cm) at all the stages during both the years of experimentation. (T1)- 140:40:40 NPK kg/ha + 45x45cm. Spacing + 20kgVermicompost/ha, (T2)-140:40:40 NPK kg/ha + 45x45cm. Spacing + 10 kg PSB/ha, (T3) -140:40:40 NPK kg/ha + 45x60cm. Spacing + 20 kg Vermicompost/ha (T4)-140:40:40 NPK kg/ha + 45x60cm. Spacing + 10kgPSB/ha (T5)-160:60:60 NPK kg/ha + 45x45cm. Spacing + 20kgVermicompost/ha, (T6)-160:60:60 NPK kg/ha + 45x45cm. Spacing +10kg PSB/ha, (T7)-160:60:60 NPK kg/ha + 45x60cm. Spacing + 20kgVermicompost/ha, (T8) - 160:60:60 NPK kg/ha + 45x60cm. Spacing + 10kg PSB/ha (T9) - 180:80:80 NPK kg/ha + 45x45cm. Spacing + 20 kg Vermicompost /ha (T10) - V180:80:80 NPK kg/ha + 45x45cm. Spacing + 10kg PSB/ha (T11) - 180:80:80 NPK kg/ha + 45x60cm. Spacing +20kgVermicompost/ha (T12) - 180:80:80 NPK kg/ha + 45x60cm. Spacing + 10kg PSB/ha (T13) - 200:100:100 NPK kg/ha + 45x45cm. Spacing + 20kgVermicompost/ha (T14) - 200:100:100 NPK kg/ha + 45x45cm. Spacing + 10kg PSB/ha (T15) - 200:100:100 NPK kg/ha + 45x60cm. Spacing + 20kg Vermicopost/ha (T16) - 200:100:100 NPK kg /ha + 45x60cm. Spacing+ 10 kg PSB/ha. The highest yield q ha 1 was recorded in treatment F4 (200:100:100 NPK kg ha 1), while minimum in F1 (140:40:40 NPK kg ha 1) during 2016-17 and 2017-18. The improvement was observed in yield q ha 1 in S1 (45 x 45 cm.) spacing over S2 (45 x 60 cm.) spacing application of B2 (PSB) recorded maximum which was at par with B1 and significantly superior over B1 (Vermicompost).
