Determination of promising varieties of (saccharum officinarum l.), soca cane year 3, in the edaphoclimary conditions of Rio Verde, Province of Santa Elena

Determinación de variedades promisorias de (saccharum officinarum l.), caña soca

Abstract

The work carried out evaluates the agronomic behavior of the sugar cane corresponding to the third soca, carried out at the Río Verde Production and Practices Center belonging to the Santa Elena Peninsula State University, it was carried out in order to determine if the cultivation maintains your productivity and profitability. Its objective was to determine the agronomic behavior of eight varieties of sugar cane (Saccharum officinarum L.), during the soca phase, year three. The vegetative material is native to Barbados, Brazil, Colombia, Cuba, Hawaii, India, the Dominican Republic and Venezuela. The Ragnar variety was used as a protective barrier. The variables that were evaluated are, plant height, stem diameter, Brix degrees and cane yield. The completely randomized block design was used, with eight treatments and three repetitions. The outstanding varieties in agricultural yield were CC 85-92 and CR 74-250, followed by V 71-51. The lowest performance figures were obtained with Co 213P and B 49-119, those that presented a higher value of Brix degrees are SP 80-1842 and CC 85-92. Determining that the varieties that expressed a better agronomic performance both in yield expressed in tons of cane per hectare, as well as in other variables, Brix degrees, plant height and stem diameter are CC 85-92 and CR 74-250 , due to their characteristics, are suitable for production in the province of Santa Elena.
