Evaluation of bitter gourd varieties on different methods of cultivation

Abstract

An experiment on evaluating bitter gourd varieties on different cultivation methods was conducted at the Agriculture Research Institute Tarnab Peshawar, Pakistan, in 2016. The experimental plots were arranged in Randomized Complete Block Design (RCBD) with split plot arrangement. Layout methods were considered the main plots, and varieties were allotted to subplots. Different varieties of Bitter gourd Kiran, Jaunpuri, and Peshawar Local were trailed on various layout ways, i.e., Vertical on net trailing method and conventional on the ground trailing method. Results showed significant variations among different layout methods. Vertically on net trailing method took minimum (39) days to flower, while maximum fruit length (17.44 cm), vine length (4.32 m), fruit diameter (4.82 cm), fruit weight (67.25 g) yield plot (12.27 kg), fruit yield (13.63 t ha), and the net return in the cost-benefit ratio was (7.69) rupees. Kiran variety produced significantly more number of fruits vine (17.6), individual fruit weight (68.02 g), fruit length (19.18 cm), vine length (4.45 m), number of branches vine(10.03) while yield plot were (12.01 kg) and fruit yield (13.34 t ha). The interaction among the layout methods and varieties showed that less number (38) of days were taken to flowering by the Kiran variety, maximum vine length (4.46 m), number of branches vine (10.03), and fruit yield (15.51 t ha) when trained vertically on the net. From these findings, it is observed that the vertical trailing method on net and Kiran variety is prominent both in production and quality.
