Abstract: A study was conducted on late planted capsicum under two production system i.e polyhouse and open environment condition with three different hormonal treatments viz. application of triacontanol @ 0.5 ml/ litre at full bloom stage, application of planofix (4.5% NAA) @ 0.25 ml/ litre at full bloom stage, application of Ethrel @ 0.3 ml/ litre at full bloom stage along with a control. Growth and yield of capsicum were significantly influenced by different hormones under both conditions. Among the hormones, planofix had best effect to result highest fruit weight (122.2g and 97.4g), number of marketable fruits per plant (5.6 and 4.2) and yield (39.4 t/ha and 28.2 t/ha) in polyhouse and open field condition respectively. Whereas, ethrel treatment resulted highest number of total fruits (8.2 and 7.2) in polyhouse and open field condition respectively. Again polyhouse was more effective to increase yield of quality fruits in capsicum than open environment condition. About 40% yield increment was recorded under planofix treatment in polyhouse than open field.
