ABSTRACT The research was performed at the Experimental Center"El Porvenir" Municipality of San Buenaventura in the department of La Paz, geographically located to 14° 20 '06' 'South latitude and 67° 36' 47 " west longitude at an altitude of 171 m. To achieve the main objective of evaluating the performance of four clones rainfed sugarcane introduced undertwo seeding the plant material was used: NA 89-1090, 85-1602 NA NA T, NAM 56-26, from the North of Argentina, all of which were assessed under the random pattern block arrangement in divided plots and three replications. The crop cycle was 12 months to reach maturity factory, using as seeding three four cuttings continuous bead end to end. The main results say the proper planting density is three seedlings per hill for optimal performance. The clone factor influences the development of the number of photosynthetically active by plant leaves and yield by weight of the stalks of sugar cane area of one hectare and this is related to plant height, diameter and population stems. Percentage rates cane fiber ranging from: 15.86 to 15.27 -14, 23 and 13,60; that fall under the reference value of 11 to 16% overthe Brix percentage JE presented values: 20.15 to 19.1 - 17.85 to 17.05 Brix JE parameters that are part of the reference value of 15 to 22%, according to these results are clones with desirable characteristics for propagation for commercial purposes. The percentage of sucrose in cane, show an overall average of 11.29% sucrose, which is normal in a reference range of 8-15% to the end of the sugar manufacturing industry is the optimal maturity reached for harvest.
