Abstract
An experiment was conducted at NPI, Bharatpur-11 Bhojad, Chitwan to assess the effect of mulching materials on vegetative increase and yield of okra. The test turned into completed in Randomized Complete Block Design. There were 5 treatments comprising T1 (Control), T2 (Black plastic), T3 (Silver plastic), T4 (Rice straw), T5 (Rice husk) which was replicated four times. Mulching effect showed significant effect on all growth and yield parameters. The effects revealed that plant top, variety of leaves, plant spreading, total number of fruits, fruit length, fruit diameter, average number of fruit, average weight of fruit/plant, and total yield among the different treatments were statistically significant. Above all treatment silver plastic mulch treatment produced the maximum fruit yield(11.070 t/ha) and had better plant height (148.7 cm), spreading (67.2 cm), number of leaves (42.5), number of fruits per plant(39.2), average fruit length (12.54 cm), average fruit weight (17.93 gm), average diameter (17.73 mm). Thus, silver plastic mulch is better for okra production at Chitwan condition of Nepal.
