Produção de chicória da amazônia cultivada sob densidades de cultivo e poda do pendão floral

Chicory is a vegetable Amazon unconventional flavor that has attracted the attention of researchers for its great versatility, which makes it a promising vegetable. However, jobs are scarce in the literature on cultivation techniques for the species. This study aimed to evaluate the effect of pruning tassel floral and different spacing, the yield on Amazon chicory. Three different spacings: E1 = 0.15 x 0.15 m, with 44 plants m(2), E2 = 0.20 x 0.20 m, with 25 plants m(2), and E3 = 0.25 x 0.25 m, with 16 plants m(2), with and without pruning floral tassel. The experiment was conducted in a randomized block design in a split plot design 3 x 2, with six replications. The characteristics evaluated were: number of leaves, fresh weight and dry weight of shoots, number of tassel floral tassel floral fresh weight, yield (kg m(-2)), and leaf area index (LAI). The largest production of chicory Amazon was obtained in plants grown at a spacing of 0.25 x 0.25 m subjected to pruning floral tassel. The highest yield for Amazon chicory was obtained in plants grown at a spacing of 0.15 x 0.15 m submitted pruning floral tassel.

Biodegradação da vinhaça resíduo da produção de etanol

The State of São Paulo is responsible for the largest sugar cane production in Brazil, as well as the largest production of ethanol made of this raw material – which is widely used as fuel for automobiles. This utilization began in the 1970’s, with the institution by the Brazilian government of the National Alcohol Program (PRO-ÁLCOOL), as a consequence of the petroleum crisis, rising again five years ago, with the development of flex fuel cars. The obtaining process of ethanol originates residues; amongst them, vinasse is the one that’s generated in the largest amount (an average of 10 to 13 litres/litre of ethanol produced). The disposal of this residue in waters was only forbidden in 1978, but before that, researchers had already been investigating its utilization as raw material. This paper had the objective of accompany the biodegradation of vinasse by evaluating the oxygen comsumption during it until the ultimate Biochemical Oxygen Demand (uBOD), performed in twenty days; another objective was to analyse the biomass production of Saccharomyces cerevisae in this residue. Physical and chemical analyses of the residue were also performed, as well as acute toxicity essays using Daphnia similis and Dugesia tigrina, before and after its biodegradation. The physical and chemical analyses pointed elevated acidness (pH = 3,98), conductivity (8,30 mS/cm) and COD (25.693,43 mg O2/L) and mean quantity of suspended solids (5.246 mg/L). The toxicity essays indicated absence of toxic potential in vinasse after biodegradation for both species. The uBOD degradated until 88,22% of the COD, demonstrating the possibility of biodegradation of most of the residue’s organic load in a relatively short period of time. S. cerevisae caused a 37,03% COD diminution in vinasse, diminished its conductivity and promoted a slight elevation of the pH; it obtained low biomass...(Complete abstract click electronic access below)

Produção e aplicação de adubo orgânico, proveniente da compostagem de resíduos da FCT/UNESP

This work presents the objective of producing organic fertilizer from the waste generated at FCT/UNESP and its use in the growing sunflower. For this, there were collected wastes of pruning/weeding and organic waste from the canteen. It were made two types of treatments, one conventional and the other mechanized, using three mass ratios: ratio 1 (30% wastes of pruning/weeding (RP) + 70% organic waste (RC)), ratio 2 (50% RP + 50% RC) and ratio 3 (70% RP + 30% RC). The conventional system was done windrow with turning manual and the mechanized system was developed in reactors by injecting compressed air. The compounds produced were analyzed in terms of pH, organic matter, organic carbon, mineral residue, nitrogen, phosphorus and potassium, which could be compared to the values stipulated by the Instrução Normativa n° 25 de 23/07/2009 do Ministério da Agricultura, Pecuária e Abastecimento. The compounds produced were used on growing sunflowers in 14 different conditions for the systems manual and mechanized, totaling 26 treatments with the following proportions...
