1. PRODUCTIVITY OF CORN HYBRIDS IN RELATION TO SOWING OVERLAP
ABSTRACT The automatic control of section shut-off in seed drills minimizes seeding overlap and can reduce productivity losses, especially in responsive crops such as corn. In that context, this study evaluated the effect of sowing overlap on the grain yield and productivity of three corn hybrids. A DB-50 precision seed drill, with 33 rows equipped with a 16

2. Methods and rates of poultry litter fertilization for corn silage in organic system
ABSTRACT. The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at

3. THERMOGRAVIMETRIC AND FTIR ANALYZES OF CORN COB PYROLYSIS
Charcoal has a large share in the Brazilian market. The production is carried out by pyrolysis of biomass at different temperatures, between 300 and 500 °C. In this study, the corn cob pyrolysis was investigated using thermogravimetric analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR). Samples after pyrolysis were compared with raw biomass t

4. Effects of storage conditions on phytochemical and stability of purple corn cob extract powder
Abstract Recently, purple corn cob has been gaining popularity for a dietary supplement and natural colorant. However, phytochemicals in waxy purple corn cob (WPC) are likely degraded during storage; thus, the microencapsulation by spray drying was used for lengthening those compounds. This work focused on the phenolic and anthocyanin content and antioxidan

5. Isolation of whiskers from natural sources and their dispersed in a non-aqueous medium
Abstract Whiskers have been used as a nanomaterial dispersed in polymer matrices to modify the microscopic and macroscopic properties of the polymer. These nanomaterials can be isolated from cellulose, one of the most abundant natural renewable sources of biodegradable polymer. In this study, whiskers were isolated from sugarcane bagasse and corn cob straw f

6. Utilization of Agro-industrial Wastes for the Simultaneous Production of Amylase and Xylanase by Thermophilic Actinomycetes
Agro-industrial wastes such as sugarcane bagasse, wheat bran, rice bran, corn cob and wheat straw are cheapest and abundantly available natural carbon sources. The present study was aimed to production of amylase and xylanase simultaneously using agro-industrial waste as the sole carbon source. Seven thermophilic strains of actinomycete were isolated from th

7. Quantitative characterization of corn plant components according to planting time and grain maturity stage
The objective of this experiment was to characterize the dry matter production of vegetative components (stalk, leaf, husk, and cob) and reproductive components (grain) of the corn plant according to planting time and the grain maturity stage. Eight corn hybrids with different agronomic characteristics were used to carry out the experiments. Two experiments

8. Bromatological evaluation of eleven corn cultivars harvested at two cutting heights
The objective of this study was to evaluate the chemical composition and dry matter in vitro digestibility of stem, leaf, straw, cob and kernel fractions of eleven corn (Zea mays) cultivars, harvested at two cutting heights. The experiment was designed as randomized blocks, with three replicates, in a 2 × 11 factorial arrangement (eleven cultivars and two c

9. Influence of stage of maturity on bromatological quality of corn forage
The objective of this study was to evaluate the effects of stalk/leaf ratio and the stage of maturity on the digestibility of the corn plant. Hybrids AG1051, AG4051, AG5011, DOW2B710, DOW2C577, DOW2A525, NB7315 and P30F90 were used, harvested at the one-half milk line (½ ML), three-quarters milk line (¾ ML) and black layer (BL) stages. A randomized block d

10. Atividades Biológicas De Xilana De Sabugo De Milho
O sabugo de milho é um subproduto agrícola ainda pouco utilizado, isto se deve em parte ao baixo conhecimento do potencial biotecnológico de suas biomoléculas. Xilana de sabugo de milho (XSM) é um polissacarídeo presente em maior quantidade na estrutura do vegetal e seu potencial biotecnológico é pouco conhecido. Este trabalho teve como objetivo a ex

11. Xylanase production by a thermo-tolerant Bacillus species under solid-state and submerged fermentation
Effects of xylose on xylanase production by a thermophilic Bacillus sp showed diverse patterns on corn cob (CC) and wheat bran (WB) as sole carbon sources in solid- state fermentation (SSF) and submerged fermentation (SmF). Supplementation of these media with either mineral salt solution (MSS) or yeast extract peptone (YEP) also exerted variable effects. Whi

12. O comportamento alimentar do turista e sua segurança no consumo de milho verde e churros à beira-mar
The aim of this research is to analyze the perceived and objective quality of the products and services offered along the sea front of the town of Balneário Camboriú in the State of Santa Catarina, considering the behavior and food safety of tourists who consume corn on the cob and churros (snacks made from fried dough with a sweet filling) sold along the
