2. Times and methods of black oat management on corn plantability
ABSTRACT The importance of maintaining straw on the soil surface is a subject widely discussed and proven in the literature. However, the effects of this straw on planting efficiency and quality still lack information. In this sense, both time and method of the black oat management influence the permanence of the straw on the soil and, thus, can interfere in

3. Hole spacing in soybean hill drop sowing1
ABSTRACT The aim of this study was to evaluate the development, yield and its components of soybean sown in hill drop method with variation in hole spacing, compared to the conventional sowing method in lines. The experiment was conducted in a randomized block design, with six treatments and four replications, using the variety M7739 RR IPRO with four plans

4. 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.

5. Nondestructive analysis of photosynthetic pigments in forage radish and vetch
ABSTRACT Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely t

6. Alternative method of sowing canola hybrids using adhesive tape
ABSTRACT Canola, which has tiny oil-producing seeds, requires care during planting, so that there is an ideal number of plants. The aim of this study is to evaluate alternative method of sowing using adhesive tape and the influence it has on the emergence and vigor of the seedlings of different canola hybrids and define the best positioning of the adhesive t

7. Equipments to manage soil and irrigated rice straw for the sequential sowing of soybean in tropical floodplains1
RESUMO A presença de palha dificulta a semeadura de soja cultivada em sucessão a arroz, em áreas irrigadas por inundação. Objetivou-se avaliar a combinação de configurações de colhedora de arroz e operações subsequentes na demanda operacional e energética do manejo da palha de arroz e na rugosidade superficial do solo, visando ao cultivo da soja

8. Thermal Requirements and Photoperiod Influence in the Leaf Development of Two Forest Species
ABSTRACT The aim of this work was to evaluate the effect of thermal time methods and to identify the phyllochron and photoperiod response in seedlings of two forest species: Corymbia citriodora and Eucalyptus urophylla. A field experiment was installed under a completely randomized design, in a 2 × 11 factorial scheme, with two forest species and eleven sow

9. Antibiofilm Activity of an Experimental Ricinus Communis Dentifrice on Soft Denture Liners
Resumo A desvantagem dos materiais resilientes é a dificuldade de controle do biofilme. Este estudo comparou um dentífrico experimental contendo Ricinus communis, com dentifrícios comerciais quanto atividade contra biofilme formado em reembasador de próteses totais. Seiscentos espécimes foram distribuídos em 5 grupos (n=18/microrganismo): água; dentif

12. Plot size and number of repetitions in vetch
ABSTRACT The objectives of this work were to determine the optimum plot size and number of repetitions to evaluate the fresh matter weight of vetch (Vicia sativa L.) in sowing densities. Fortyeight uniformity trials of 6 m × 6 m were conducted. Sixteen trials were evaluated in each sowing density (40, 60, and 80 kg∙ha−1). Each trial was divided into 36
