Stages of vine pruning for vine production of bottle gourd varieties and lines in summer season

Abstract

Four bottle gourd varieties and lines (V1: BARI and three pruning stages (P1: Pruning at two vine stage, P2: Pruning at 3 vine stage and P3: Pruning at 4 vine stage) were implied to observe the effect of pruning on the maximization of vine production in bottle gourd. V4 produced maximum number of vine (117.2/plant) and highest vine yield (10.2 t/ha) among four varieties while P3 produced maximum number of vine (109.2/plant) and highest vine yield (9.1 t/ha) among three pruning techniques. The maximum number of harvested vine (118.0/plant) and highest vine yield (10.73 t/ha) was found from V4P3 which was statistically followed by V4P1 and the lowest vine yield was recorded from V2P1 (6.62 t/ha). LS 0026-5-3 along with pruning of terminal shoots four vine stages can be recommended for better vine production in bottle gourd for use as leafy vegetable.
