Abstract: CRUCIDO, CELSO S., Don Severino Agricultural College, September 1991. Intercropping Sweet Potato with Bush Sitao and Okra. Major Adviser: Dr. Reynaldo C. Ersando. The study was conducted to (i) evaluate the effect of different intercrop treatments on the growth and yield of sweet potato; (2) identify the most suitable intercrop for sweet potato under upland Cavite condition (3) assess the cost and return of intercropping sweet potato with bush sitao and okra. Sweet potato grown in monoculture had significantly produced the longest vines at all stages of growth, highest number of marketable tuber, fresh weight of marketable tubers per plot and highest fresh weight of tuber per plant. However, lowest non-marketable tuber of sweet potato was obtained in monoculture. Highly significant interaction was noted between sweet potato and intercropping treatment especially on the number of marketable tuber of sweet potato per plot and fresh weight of tuber per plant. Results further indicated that when bush sitao + okra were used as intercrop to Georgia Red and VisCA I cultivars, the plants turned to produce shorter vines, lower number of marketable and fresh weight of tuber; and a higher number of non-marketable tubers. Likewise, when bush sitao and okra were planted together in between the rows of sweet potato, all crops involved in the combination gave a significantly lower yield suggesting a severe interplant competition for all factors affecting growth and development. With regards to intercropping, the Land Equivalent Ratio (LER) and yield efficiency of various intercropping treatment was significantly higher in sweet potato + bush sitao combination. However, none of the intercropping treatment had LER above one, suggesting a net negative effect. Generally, considering the net profit obtained from different intercropping treatment, sweet potato + bush sitao combination gave the highest net return among all the intercropping combination used. The lowest net profit was obtained from the sweet potato + okra intercropping combination.

CRUCIDO, CELSO S., Don Severino Agricultural College, September 1991. Intercropping Sweet Potato with Bush Sitao and Okra. Major Adviser: Dr. Reynaldo C. Ersando.

The study was conducted to (i) evaluate the effect of different intercrop treatments on the growth and yield of sweet potato; (2) identify the most suitable intercrop for sweet potato under upland Cavite condition (3) assess the cost and return of intercropping sweet potato with bush sitao and okra.

Sweet potato grown in monoculture had significantly produced the longest vines at all stages of growth, highest number of marketable tuber, fresh weight of marketable tubers per plot and highest fresh weight of tuber per plant. However, lowest non-marketable tuber of sweet potato was obtained in monoculture.

Highly significant interaction was noted between sweet potato and intercropping treatment especially on the number of marketable tuber of sweet potato per plot and fresh weight of tuber per plant. Results further indicated that when bush sitao + okra were used as intercrop to Georgia Red and VisCA I cultivars, the plants turned to produce shorter vines, lower number of marketable and fresh weight of tuber; and a higher number of non-marketable tubers.

Likewise, when bush sitao and okra were planted together in between the rows of sweet potato, all crops involved in the combination gave a significantly lower yield suggesting a severe interplant competition for all factors affecting growth and development.

With regards to intercropping, the Land Equivalent Ratio (LER) and yield efficiency of various intercropping treatment was significantly higher in sweet potato + bush sitao combination. However, none of the intercropping treatment had LER above one, suggesting a net negative effect.

Generally, considering the net profit obtained from different intercropping treatment, sweet potato + bush sitao combination gave the highest net return among all the intercropping combination used. The lowest net profit was obtained from the sweet potato + okra intercropping combination.
