Yield and biometry of fertilized sugar cane with organomineral fertilizer of sewage sludge and biostimulant

Abstract

The dependence of mineral fertilizers, increasingly, has brought concern facing the increased demand and because it is a non-renewable mineral resource. The organic fertilization, exclusively, it is impractical in large scale, however, the combination of organic and mineral sources have already proved to be feasible, both from the point of view of nutrition of plants as well as in the aspect of recycling of urban and industrial waste by agriculture. This research had as objective to determine the efficiency of aorganomineral fertilizer formulated on the basis of sewage sludge in substitution of mineral fertilizer in the cultivation of sugar cane in environments with different levels of soil fertility. An experiment was conducted in greater soil fertility, in the Institute Federal Goiano– Campus, Morrinhos-GO, Brazil. The other, less soil fertility, was implanted in the ethanol industry Tijuco Valley, located in Rio do Peixe, district of Prata-MG, Brazil. The experimental design was randomized blocks in a factorial 5 x 2 +1 being five doses, with and without a biostimulant plus an additional with mineral fertilization, in four replications. The doses were in function of fertilization recommendation of planting and coverage for each environment, consisting of: 100 % of the mineral source and percentage 0; 60; 80; 100 and 120 % of organomineral fertilizer. We evaluated the productivity, tillering, diameter and height of stem in Prata-MG the different percentages of the fertilization of planting favored and increased productivity, height and stem diameter of sugar cane; the use of biostimulants not contributed to increase crop yield. In Morrinhos-GO, the different percentage of planting fertilization did not increase the productivity, tillering, height and diameter of the sugarcane stem; the use of biostimulants increases the productivity yield of sugarcane. Organomineral fertilizer based on biosolids is similar to fertilization with mineral fertilizer in environments.

“…There was no difference among treatments for stem length (Figure 3a). Similar results were reported by Moraes et al [43] who studied the vegetative and biometric development of sugarcane fertilized with organo-mineral fertilizer based on sewage sludge and biostimulants. Treatments also did not influence stem diameter at 150 days after planting (Figure 3b).…”

Chemical and technological attributes of sugarcane as functions of organomineral fertilizer based on filter cake or sewage sludge as organic matter sources

“…The sewage sludge chemical characteristics satisfied the standards prescribed by CONAMA Resolution No. 375/2006 [ 19 ], and the values were close to those reported by Moraes et al [ 33 ].…”

“…The yield and productivity of sugarcane and other crops are influenced by the quantity and balance of nutrients in the soil. Sugarcane productivity, plant height, and stem diameter are positively correlated with organomineral fertilizer application rates at planting [ 33 ]. In sorghum, a plant in the Poaceae family and morphologically and physiologically similar to sugarcane, organomineral fertilizer supplementation influences ethanol, reducing sugars, and total recoverable sugars production [ 34 ].…”

“…The use of sewage sludge has already been demonstrated to be feasible from a sanitary point of view [ 30 ], through disinfection at high efficiency and from an agronomic perspective for the fertilization of sugarcane [ 33 ]. Sewage sludge-based fertilizers supplemented with mineral fertilizers are viable alternatives and improve agronomic parameters; however, an evaluation of their effects on industrial sugarcane yield parameters is required.…”

A Tool Derived from the Vicia faba Micronucleus Assay, to Assess Genotoxicity, Cytotoxicity or Biostimulation of Novel Compounds Used in Agriculture

“…Alternatives to conventional biostimulants have made use of wastes from agriculture [24] and from cities [25], nanoparticles and nanomaterials [26], composts [27], sewage sludge [28] and waste-water from processing industries [4]. These novel alternatives may present potential risks to living organisms.…”
