Abstract
El objetivo del presente trabajo fue evaluar el rendimiento a secano de cuatro clones introducidos de caña de azúcar bajo dos densidades de siembra. La investigación fue realizada en el departamento de La Paz, geográficamente localizado a 14° 20' 06'' latitud Sur y 67° 36' 47'' longitud Oeste y a una altitud de 171 msnm. Se empleó el material vegetal: NA 89-1090, NA 85-1602, NA Playera, NAM 56-26, procedente del Norte de Argentina, mismos que fueron evaluados bajo el modelo bloques al azar con arreglo en parcelas divididas y tres repeticiones. El ciclo vegetativo del cultivo fue de 12 meses hasta alcanzar la madurez fabril, empleando como densidad de siembra tres y cuatro esquejes a cordón continuo punta con punta. Los principales resultados muestran que la densidad de siembra adecuada es de tres esquejes por surco para obtener un rendimiento óptimo. El factor clon tiene influencia en el desarrollo del número de hojas fotosintéticamente activas por planta y en el rendimiento en peso de los tallos de la caña de azúcar para superficie de una hectárea y este está relacionado con la altura de la planta, diámetro y población de tallos. Los índices en porcentaje de fibra en caña fluctúan entre: 15,86; 15,27; 14,23 y 13,60; que se enmarcan en el valor de referencia de 11 -16%. Respecto al porcentaje °Brix J.E. presentaron valores de: 20,15 - 19,1 - 17,85 -17,05 °Brix J.E. parámetros que se enmarcan en el valor de referencia de 15 - 22%, de acuerdo a estos resultados son clones con características deseables para su propagación para fines comerciales. El porcentaje de sacarosa en caña, muestra un promedio general de 11,29%, que es considerado un valor normal en un rango de referencia de 8 a 15% que para fines de la industria azucarera es la madurez fabril óptima alcanzada para la cosecha.
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.
