Coffee productivity during intercropping with five leguminous species in the western region of Sao Paulo State, Brazil
Coffee (Coffea canephora) productivity was evaluated during three years of intercropping with five leguminous species: sunn hemp (Crotalaria juncea), Crotalaria spectabilis, dwarf velvet bean (Stizolobium deeringeanum [Mucuna pruriens]), soyabean (Glycine max), and pigeon pea (Cajanus cajan) in the western region of Sao Paulo State, Brazil from 1991 to 1993. Leguminous species were sown 50 cm away from the coffee shoot and incorporated at flowering stage. Coffee yield was not affected when Crotalaria spectabilis, dwarf velvet bean and soyabean cv. IAC 9 were used as interrow crops, while pigeon pea and sunn hemp treatments significantly decreased yield. Linear correlation analysis showed that coffee yield was inversely correlated with leguminous drybiomass and positively correlated with coffee shoot height and stem diameter during the harvest year.
