Abstract:
study was undertaken to find out the effect of spacing and bud pruning on the
growth and yield of brinjal (cv. 'Khotkhotia'), The experiment was conducted at
Sher-e-Bangla Agricultural University, during March to September 2006. Three
different spacing S1 (60 cm x 60 cm), S2 (80 cm x 80 cm) and S3 (100 cm x I 00
cm) and three types of bud pruning; P0 (without pruning), P1 (pinching off of the
lateral bud), P2 (Pinching off of the terminal bud) were tested. The experiment was
laid out in a Randomized Complete Block Design (RCBD) with three replications.
Increasing the spacing increased the number of branches per plant, number of
leaves per plant, number of flowers per plant, average number of fruits per plant
and individual weight of fruit. Number of branches ( 14.11 ), number of leaves
(I 00.2) and length of lamina (19.2 cm) was the highest in S3. Number of flowers
(12). number of fruit (18.47) and individual weight of fruit (90.24 g) was the
highest in S3• The closest spacing S
gave the highest number of fruits per plot
(68.50) but the total yield of fruit per plot was the highest in S3 ( 1677 g). Neither
spacing nor bud pruning had any significant influence on the plant height of
brinjal. P2 produced the highest number ( 17. 7) of branches and leaves (I 0 I. 78). P
1
gave the largest size (88.84 g) of fruits compared to P2 (84.47 g). The result of the
present study showed that the widest spacing (S3) and lateral bud pruning (P
gave the highest yield per plant. Further study could be undertaken with spacing
higher than S3 (100 cm x 100 cm) and pinching off of the lateral bud
