Vertical distribution of root system in five sugar cane cultivars.

Hernandez A. Vertical distribution of root system in five sugar cane cultivars.

Irrigation and Drainage Series Vol.8, Nº 1: 7-20, 1985, Cuba.

In the Irrigation and Drainage Experimental Station of the Havana province, studies of root system in five sugar cane cultivar were carried out. The plants were cultivated in a Red Ferrallitic Compacted soil under irrigation conditions; to take out roots soil probes of type agrologic were used. This method possibility estimates of root relative values so permit it use in the sugar cane. It was determined that the first 0.50 meter of soil depth was founded the major percentage of actives roots.

A high significant correlation between roots and soil moisture extracted was recorded and ranged from 0, 87 to 0, 96 for the different cultivars. To calculate water irrigation requirements may be used 0.30 m. soil depth to sealed crop and the other vegetative cycle 0, 50 m depth must be used, considering the agrotecnic and soil aspects.
