The 4 levels of ethephon made significant differences for days to first fruitset and days to first red chilli harvest. Yield increased with ethephon application though it was not statistically significant. Plant stature was affected resulting in dwarf plant habit. Differential response to ethephon application was recorded only for days to first fruitset. Ethephon has only a limited use in chilli.ennullArticle
