Abstract

The objective of this work was to evaluate the dry yield of four introduced clones of sugarcane under two seed densities. The research was carried out in the department of La Paz, geographically located at 14º 20 '06' 'South latitude and 67º 36' 47 '' West longitude and at an altitude of 171 meters. The plant material was used: NA 89-1090, NA 85-1602, NA Playera, NAM 56-26, from the North of Argentina, which were evaluated under the random blocks model in divided plots and three replicates. The vegetative cycle of the crop was of 12 months until reaching the maturity factory, employing like seed density three and four cuttings to continuous cord tip with tip. The main results show that the appropriate seed density is three cuttings per row for optimum yield. The clone factor influences the development of the number of photosynthetically active leaves per plant and the yield by weight of sugarcane stems for one hectare surface and this is related to plant height, diameter and population of Stems The percentage rates of cane fiber fluctuate between: 15.86; 15.27; 14, 23 and 13.60; Which are framed in the reference value of 11 - 16%. Regarding the percentage ºBrix J.E. Presented values ​​of: 20.15 - 19.1 - 17.85 - 17.05 ºBrix J.E. Parameters that are framed in the reference value of 15 - 22%, according to these results are clones with desirable characteristics for their propagation for commercial purposes. The percentage of sucrose in cane, shows an overall average of 11.29%, which is considered a normal value in a reference range of 8 to 15%, which for the purposes of the sugar industry is the optimum manufacturing maturity reached for the harvest.
