AGRO-INDUSTRIAL EVALUATION OF NEW HYBRIDS OF SUGAR CANE (Saccaharum spp.) IN THE DRY TROPIC UNDER NO WATERING CONDITIONS

Abstract

Objetive: The objective of this research was to select new sugarcane hybrids with better adaptation and performance in the field and industrial within the supply area of ??the Quesería sugar mill of the Beta San Miguel group (BSM).

Design/methodology/approach: A group of 11 new hybrids were established in the agroindustrial phase, in order to compare their adaptation and field and the industrial performance using the commercial hybrid Mex 69-290 as control.

Results: The results obtained indicated that during the soca cycle and under local soil conditions, the hybrids ColMex 05-484, ColMex 05-38 (c9) and ColMex 05-627, demonstrated the highest estimated field yields, with values ??of 154, 149 and 143 t / ha-1 respectively. Regarding the highest values ??of percentage of sucrose in cane (Pol), at 12 months of age of the plant, it was obtained by the hybrids ColMex 05-147 (16.8%), ColMex 08-38 (C8) (16.5%) and ColMex 05-897 (16.1%), considered by its intermediate cycle maturation curve.

Limitations on study/implications: The limitations that could affect the results of the investigation were; the abundance of stones on the topsoil and the poor distribution of rainfall during the development of the crop (1203 mm).

Findings/conclusions: It can be concluded that after analyzing the agricultural and industrial performance that, the best hybrid was: ColMex 05-484, surpassing the commercial control Mex 69-290.
