Evaluation of four types of fertilizers applied to the soil in seedbeds of Saccharum
officinarum, L., sugarcane, at Las Palmas farm, San Antonio, Suchitepéquez.
At present, the increase in prices of chemical fertilizers and the lack of knowledge of the
nutritional contribution of organic fertilizers (sowing), has caused some sugarcane
producers not to provide the proper nutrition to the sugarcane plant, which is reflected in
the yields at the time of cutting.
The research was carried out with the purpose of increasing the sugarcane crop yield
(Ton/ha) and reducing production costs. For this research, the CG-9878 variety was used,
giving the same agronomic management to all experimental units.
Two doses of chemical fertilizers were evaluated, one dose recommended by personnel
from the Tululá sugar mill and the other dose required by the soils prior to soil analysis;
and two organic fertilizers, sow and poultry manure; in addition to a relative control
(without soil fertilization).
The response variables measured in this research were the following: number of
packages/ha (one package is 30 sugarcane cuttings of 60 cm each), morphological
variables of stem length, stem diameter, number of viable buds and the percentage of
sugarcane germination.
In each of the variables measured in the research, the result was that treatment three
(required dose of fertilizer) was statistically the best treatment evaluated in each of the
experimental units.
The financial analysis showed that treatment 2 (recommended dose of chemical fertilizer)
obtained the best benefit-cost ratio of the research, being 1.39 with a profitability index of
39%. |
