EFFECT OF NITROGEN AND SPACING ON THE GROWTH AND YIELD OF CABBAGE

Abstract

An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from October 2012 to February 2013 to study the effect of nitrogen and spacing on the growth and yield of cabbage. The experiment was laid out in a Randomized Complete Block Design with three replications and includes of Factor A: four levels of urea; N 0 : Control, N , N 2 : 250 kg ha -1 and N 3 : 350 kg ha -1 , and Factor B: three plant spacing; S (50 cm x 30 cm), S 2 (50 cm x 40 cm) and S (50 cm x 50 cm). At 80 DAT the highest plant height (37.2 cm), diameter of head (19.5 cm) from N 3 but fresh weight of head (2.1 kg from N 2 ) was found from N 2 and the lowest from N 3 . On the other hand, at 80 DAT the highest plant height (35.3 cm), diameter of head (19.2 cm) and fresh weight of head (1.8 kg) were found in S (2.3 kg from N 2 S 3 3 and the lowest from S ) and marketable yield (128.9 tha 0 1 1 :150 kg ha 1 . The highest fresh weight of head -1 ) were recorded from N and, the lowest fresh weight of head

(1.1 kg from N 0 S 1 ) and marketable yield (53.3 tha ) from N . The maximum benefit-cost ratio (4.7) was recorded in the treatment combination of 250 kg urea ha 0 S 3 -1 with spacing 50 cm × 30 cm(N ) while the lowest in N 0 S (2.1). So, it can be concluded from economic point of view, 250 kg urea ha

-1 3 with spacing 50 cm × 30 cm is suitable for growth and yield of cabbage.
