1. Use of mineral particle film to protect ‘Okitsu’ tangerine and ‘Valencia’ orange against Anastrepha fraterculus and the effect on fruit quality
ABSTRACT The particle film technology has been reported as a promising tool in pest control. The objective of this work was to evaluate the efficiency of kaolin-based products against the oviposition of South American fruit fly, Anastrepha fraterculus (Dip.:Tephritidae), and its effect on the quality of citrus fruits. The experiment was conducted in orchards

2. Agronomic performance of soybeans with the presence of volunteer RR corn
ABSTRACT The presence of volunteer corn plants among soybeans, both resistant to glyphosate, has increased in recent years in Brazil. The objective of this study was to quantify the impact on the agronomic performance in RR soybeans by the presence of volunteer RR corn in field conditions. The experiment was conducted in Tiradentes do Sul (RS), 2018/19 harve

3. Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method
ABSTRACT Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in the post-harvest. The leaf area measurement is fundamental in plants because the leaves are directly related to several processes such as transpiration, radiation interception and CO2 fixation that enable the plant to grow. The objective of t

4. Productivity and postharvest durability of Heliconiaceae grown in full sun in the Midwest region of Brazil
ABSTRACT Flower stems of the Heliconiaceae family are gaining more and more space in the Brazilian market of ornamental plants and further knowledge about quality, productivity, and postharvest management is necessary. The objective of the present study was to evaluate heliconiaceae cultivated in full sun in the central-west region of Brazil in terms of agro

5. Base-temperature, plastochron and chia (Salvia hispanica L. - Lamiaceae) yield for different sowing times
ABSTRACT Chia is a plant whose seeds are used in cooking and is a natural source of omega-3 fatty acids, fiber and protein, as well as other important nutritional components such as antioxidants. The objective of this work was to estimate the base temperature, plastochron and chia seed yield for different sowing times in Cruz Alta, Rio Grande do Sul, Brazil.

6. GROWTH PROMOTION OF GENETICALLY IMPROVED Pinus taeda SEEDLINGS BY INOCULATION WITH SPECIES OF Bacillus.
ABSTRACT This study was carried on evaluating effects of inoculation with Bacillus species and generations of genetically improved seeds on Pinus taeda growth in nursery conditions. Two experiments, based on distinct inoculation methods (sowing and post-emergence) were performed under a 3 x 2 factorial, completely randomized block design (3 levels of inocula

7. Pre-harvest desiccation in biomass sorghum with herbicides
ABSTRACT The purpose of this study was to assess the effect of different herbicide treatments on moisture removal and calorific power of biomass sorghum for co-generation of electric energy through burning. The experiment was conducted in randomized complete block design with four replicates per treatment and a 6x4 factorial scheme (six herbicide treatments

8. Amaranth in southernmost latitudes: plant density under irrigation in Patagonia, Argentina
ABSTRACT In Argentina there have been few evaluations of Andean pseudocereal plantings. This study explored the response of Amaranthus cruentus cv Mexicano to different plant densities under furrow irrigation in the lower valley of the river Negro, Patagonia, Argentina. The experimental design consisted of 3 blocks with randomized treatments (subplots), each

9. Arbuscular mycorrhizal fungi action on the quality of strawberry fruits
RESUMO A inoculação de fungos micorrízicos arbusculares (FMAs), aumentando sua influência rizosférica, pode induzir maior biossíntese de compostos bioativos em plantas. Dessa forma, objetivou-se avaliar a influência da inoculação de FMAs nos componentes físico-químicos de frutos de cultivares de morangueiro cultivadas a campo. Utilizaram-se frutos

10. Phenological behavior and agronomic potential of blackberry and hybrids in a subtropical region
ABSTRACT The purpose of this study was to evaluate the phenological behavior and agronomic potential of blackberry varieties and hybrids in a subtropical region. Blackberry seedlings of four varieties and two hybrids were purchased in April 2015 in the form of stem cuttings and transplanting in July 2015. Winter pruning was carried out on August 18, 2016 and

11. Growth and yield parameters of white oat and wheat as affected by canola residues
ABSTRACT Despite being an important crop option for Brazilian agriculture, canola has some characteristics that may limit its insertion in some cropping systems, such as its allelopathic effects. Thus, the present work aimed to study the effect of canola crop residues on the seed germination, growth and grain yield of white oat and wheat plants. In laborator

12. Adubação nitrogenada e intervalos de colheita na produtividade e nutrição da erva-mate e em frações de carbono e nitrogênio do solo
Resumo Na erva-mate (Ilex paraguariensis) o principal produto colhido é composto por folhas (FO) e galhos finos (GF), resultando em elevada exportação de nutrientes, dentre eles o N. As informações técnico-científicas disponíveis para subsidiar uma recomendação da adubação nitrogenada racional são insuficientes, o que põe em risco a sustentabil
