Naturally, it did not all mature at once, but I had planted in such succession that I could grind for nine months steadily, while more was being planted and the ratoons
were springing up.
It can be harvested every 85 days in three ratoons
, a practice of growing a crop from the stubble of previous crop without replanting thus making it cheaper to produce.
1 accumulated 50.1% less degrees days (DD) in relation to the plant-cane, and ratoons
2 and 3 accumulated 38.4% and 55.3% less DD, respectively.
Although statistical differences between ratoon
stages were not found in either total above or belowground biomass, a decreasing trend with the number of ratoons
was observed for aboveground biomass.
Additionally, given the fact that the renewal period of the sugarcane in the Valle del Cauca state is, on average, each 5 cuts, we determined the generated emissions during the preparation of one soil in renovation--i.e., ratoons
in the cut 0--.
In the 1st and 2nd ratoons
, the effective rainfall contributed equally to the expression of the productive potential and biometry of the evaluated cultivars, and the probable detected differences were due to the greater contribution of the irrigation applied notably in the period prior to the rainy season.
(cultivar 'RB855536') were used, following mechanical harvest performed in October 2012.
It is considered a primary sugarcane pest because of the direct damage that its larvae cause to stem tissues, mainly in the dry season (June to August), causing the death of ratoons
and consequent gaps in regrowth, thereby increasing the incidence of invasive plants that compete with the crop.
The average millable and sugar yield of plant cane, 1st and 2nd ratoons
showed significant increases (13- 19%) and (21-30 %) respectively, for all tested compounds except Algifert where it gave a slight sugar yield increase (4 %).
Her rice farm (84 hectares in all) is non-irrigated but the ratoons
have grown very well by just depending on the rain.
Although three ratoons
(new cuts from the same cane plant) were considered to be the optimum, usually many more ratoons
are important for overall profitability of sugarcane cultivation as they save about 30% in the operational cost, mainly that of seed and reduced expenses for soil management (Sundara, et al., 1992).
