Effect of head manipulation techniques and planting distance on seed yield and yield contributing parameters of cabbage (Brassica oleracea var. capitata)

Abstract

The present investigation was conducted during Kharif of
2014 and Rabi of 2015 at the experimental farm of Department
of Vegetable Science, V.C.S.G. Uttarakhand University of
Horticulture and Forestry, Ranichauri Campus, Tehri-Garhwal
with cabbage cultivar Golden Acre. The experiment was laid
out in two factor Randomized Block Design (RBD) with three
replications includes three head manipulation techniques
viz., Stump method (T1), Stump with central core intact
method (T2) and Head intact method (T3) and four different
planting distance viz., 60x60 cm (S1), 60x45 cm (S2), 45x40 cm
(S3) and 40x30 cm (S4). The results of the study revealed
significant differences among the treatments, stump method
(T1) exhibited earliest flowering (92.75 DAT), seed maturity
(140.56 DAT), maximum number of primary branches per
plant (47.12), siliqua per primary branch (65.81), seed yield
per plant and per hectare (20.21 g and 9.01q) respectively.
Whereas planting distance of 40x30 cm was found promising
for days to 50 per cent flowering (102.0 DAT), seed maturity
(154.0 DAT) and seed yield per hectare (9.99q). The stump
method accompanied with 60x60 cm spacing gave highest
seed yield per plant (23.03 g) However, maximum seed yield
was realized in stump method along with 40x30 cm planting
distance (10.50q/ha).
