Abstract: PASCUAL, ARNULFO C,, Institute of Graduate Studies, Central Luzon State University, Mufoz, Nueva Ecija, October 1985. Productivity of Selected Upland Gabi Cultivars Intercropped with Corn, Peanut and Sweet Potato. Major Advisers Dr. Josue A. Irabagon The experiment was conducted to determine the influence of different. intercrops on the productivity of selected upland gabi cultivars. Gabi grown in monoculture had a significantly higher number of marketable cormels with similarly greater length and diameter, greater leaf area index (LAI) and dry weight but with slightly shorter petioles compared to those grown with sweet corn. Highly significant interaction was noted between variety and intercropping pattern particularly on the weight of harvested cormels, Results further indicate that when peanut was used as intercrop to Dasheen and Tininta cultivars, the plants tended to produce shorter petioles due to shading effects offered by the intercrop which grew close to the height of the cultivars mentioned. On the other hand, the weight of harvested cormels and LAI of San Fernando cultivar was significantly affected by sweet potato. This was probably due to its late bulking characteristics which commenced at almost the same time with the intercrop, resulting in a strong competition for soil moisture and nutrients. Likewise, when sweet corn and peanut were grown together between rows of gabi cultivars, all the crops involved in the combination gave a significantly lower yield suggesting a severe interplant competition for all factors affecting growth and development. In relation to monoculture, the Land Equivalent Ratio (LER) and yield efficiency of various intercropping scheme was significantly higher in corn + gabi combination, However, none of the intercropping patterns had LER above 1 suggesting a net negative effect. Generally, considering the net profit obtained from each intercropping scheme, corn + gabi combinations gave the highest net returns among all the intercropping combinations used.

The experiment was conducted to determine the influence of different. intercrops on the productivity of selected upland gabi cultivars. Gabi grown in monoculture had a significantly higher number of marketable cormels with similarly greater length and diameter, greater leaf area index (LAI) and dry weight but with slightly shorter petioles compared to those grown with sweet corn.

Highly significant interaction was noted between variety and intercropping pattern particularly on the weight of harvested cormels, Results further indicate that when peanut was used as intercrop to Dasheen and Tininta cultivars, the plants tended to produce shorter petioles due to shading effects offered by the intercrop which grew close to the height of the cultivars mentioned.

On the other hand, the weight of harvested cormels and LAI of San Fernando cultivar was significantly affected by sweet potato. This was probably due to its late bulking characteristics which commenced at almost the same time with the intercrop, resulting in a strong competition for soil moisture and nutrients.

Likewise, when sweet corn and peanut were grown together between rows of gabi cultivars, all the crops involved in the combination gave a significantly lower yield suggesting a severe interplant competition for all factors affecting growth and development.

In relation to monoculture, the Land Equivalent Ratio (LER) and yield efficiency of various intercropping scheme was significantly higher in corn + gabi combination, However, none of the intercropping patterns had LER above 1 suggesting a net negative effect.

Generally, considering the net profit obtained from each intercropping scheme, corn + gabi combinations gave the highest net returns among all the intercropping combinations used.
