From the experiment it can be concluded that intercropping of onion seed crop with
sugarcane does not have any adverse effect on growth, yield and juice quality of
sugarcane. Onion seed crop intercropping was economically more profitable than sole
cane and the highest economic benefit was obtained from the onion seed crop-
