To maximize land use in small farms and increase income, intercropping mulberry with corn, peanut, and onion was done. Based on mulberry leaf yield performance and income from the intercrop and cocoons, peanut is the best intercrop followed closely by corn. Onion requires high labor input hence, is not a good source of income. To predict the sustainability of intercropping peanut or corn to mulberry for a period of 10 years, an intercropping data from 1995-1997 was fitted into the SCUAF model of Young and Muraya (1989). Results revealed a very minimal decrease of soil organic C, N, and P for the next 10 years hence, a sustainable supply of those elements for the growth of mulberry and intercrop. Between the intercropped mulberry and mulberry alone, the decrease is sharper in the former because of lower rate gains from humification and greater losses from oxidation. Income trend will remain stable. Reducing mulberry branches to 5 and 7 per tree is an effective and sustainable component of the intercropping technology because growth of the intercrop is enhanced and better leaf harvest is produced. Eventually, good quality cocoons and high net returns from cocoons intercrop product is attained
