Effect Of Alley Size And Hedgerow Pruning Interval On Phenology And Yield Of Okra [<i>Abelmoschus Esculentus</i> (L.) Moench] In Hill Slope

Abstract

An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from May 2002 to November 2004 to find out the effect of alley size (3.0 , 4.0, and 5.0 m) and hedgerow pruning interval (1, 2, and 3 months) on phenology and fruit yield of okra in hill slope condition during the rainy season. The highest fruit yield (16.14 t/ha) was produced by the plants grown in 3.0 m size alley. In case of hedgerow pruning interval, the highest yield (16.07 t/ha was recorded from 2 months pruning interval and it was significantly different with other two pruning intervals. The treatment combination of 3.0 m size alley with I month pruning interval produced significantly highest yield (17.67 t/ha). The highest gross return (Tk.176700/ha), net return (Tk.120380/ha) and BCR (3.14) were also found from the same treatment though highest cost of production was involved in this treatment.  

Key words: Alley size; pruning interval; phenology; okra yield; cost benefit.
