Vegetative growth of cabbage (Brassica Oleracea var. Capitata l.). cv. Pusa drum head in relation to plant spacing, boron and molybdenum

In order to evaluate the effect of boron, molybdenum and spacing on different growth and development of cabbage. Field experiment was conducted during the rabi of 2013-14 and 2014-15. Two spacing 60 x 60 (S1) and 60 x 45 (S2) and three levels of each Boron and Molybdenum i.e. B1- (Boron @ 0%), B2- (Boron @ 0.25%), B3- (Boron @ 0.5%), and M1- (Molybdenum @ 0%), M2- (Molybdenum @ 0.25%), M3- (Molybdenum @ 0.5%) were in FRBD with three replications. Foliar spray of boron and molybdenum was done at 30 and 50 days after planting (DAP) and all other cultivation practices were adopted as per recommendations. Spacing S1 recorded higher value for plant height 36.94 cm, plant spread 94.43 cm2, leaf length 27.90 cm, leaf width 23.85 cm, no. of open leaves 16.11 and diameter of head 17.06 cm. Among the boron levels 0.5% boric acid increased all the vegetative character viz. plant height 37.53 cm, plant spread 94.41 cm2, leaf length 28.45 cm, leaf width 24.93 cm and diameter of head 16.15 cm. In case of molybdenum @ 0.5% recorded the maximum value for the plant height 36.41 cm, plant spread 93.28 cm2, leaf length 27.32 cm, leaf width 23.50 cm and diameter of head 15.31 cm.
