Previous studies on intercropping in sugarcane have reported
variable effects of intercrops on sugarcane yield. Shukla and Pandey
(1999) in India and Ali et al. (2001) in Pakistan recorded no adverse
effects of mustard and lentil intercropping on cane yield. Cadersa
et al. (2001) from Mauritius reported similar cane yield from
sole and potato intercropped sugarcane. Similarly, the intercropping of velvet bean (Mucuna deeringiana), sugar bean (Phaseolus limensis) and sweet potato (Ipomoea batatas) recorded no adverse effect on cane yield (Berry et al., 2009). In contrast, sugarcane intercropped with sunflower reduced cane yield than sole sugarcane (Afzal et al., 2003). Similarly, Munoz et al. (2001) in Cuba obtained lower yield of sugarcane intercropped with peanuts or maize fodder, however, the total system productivity and profitability from intercropping was greater than sole sugarcane.
