Effects of Row Intercropping System of Corn and Potato and Row Spacing of Corn on the Growth and Yields of Atlantic Potato Cultivar Planted in Medium Altitude

Jajang Sauman Hamdani and Yayat Rochayat Suradinata

Abstract: The objective of this research was to study the growth and yield of Atlantic Potato cultivar grown in medium altitude under corn and potato intercropping system and corn row spacing. The experiment was conducted in a research station of Agriculture Faculty of Padjajaran University located in Jatinangor at the altitude of 685 m above sea level with C3 rainfall in Inseptisol soil. It was laid out in Split Plot Design consisting of two factors and four replications. Manipulating growing environment by using corns as shades under different cropping systems was created as the main plot factor which consisted of two cropping systems: 1:1 corn+potato arrangement (one row of corns, one row of potatoes) and 1:2 corn+potato arrangement (one row of corns, two rows of potatoes). The row spacing of corn planted within the rows as the subplots were at 30, 40 and 50 cm. Results of the research indicated that there were no interactions between the corn and potato cropping system and the corn row spacing system over their growth, yields and Land Equivalent Ratio (LER). The plants height of potatoes and their leaf area under 1:1 arrangement were larger compared to those under 1:2 arrangement. On the other hand, the dry mass and the chlorophyll concentrations showed lower value. Although they yield the equal crops, the weight per plot, the yields per hectare and the LER value of 1:1 corns+potatoes cropping system showed higher result. While the row spacing system of corn at 50 cm showed higher value of dry weight, yield per plant, weight per plot and yield per hectare, yet it showed lower value of LER.
