1. Interaction between growth strategies and phosphorus use efficiency in grasses from South America natural grasslands
ABSTRACT South American natural grasslands are composed of several species with different growth strategies, with variations in specific leaf area (SLA), leaf dry matter content (LDMC), specific root length (SRL) and specific root area (SRA). The objective of this study was characterizing in grasses cultivated with different levels of phosphorus (P) in the s

2. INFLUENCE OF DRAINAGE METHODS ON SOYBEAN DEVELOPMENT IN LOWLANDS
ABSTRACT The need for crop rotation and profitability in lowland areas are the two main reasons for the introduction of soybean cultivation in the state of Rio Grande do Sul, Brazil. These areas have poor natural drainage, which impedes proper soybean growth. In this sense, this study aimed to assess the efficiency of using broad base ridges in comparison to

6. Development of a weather-based forecasting model for Alternaria leaf blight of carrot
RESUMO No presente trabalho foram estudadas, em condições de câmara climatizada, a influência da temperatura (10, 15, 20, 25 e 30°C) e da duração do molhamento foliar (6, 12, 24 e 48 horas) na severidade da queima das folhas da cenoura incitada por Alternaria dauci. A densidade relativa de lesões foi influenciada pela temperatura e pela duração do

7. MINI-CUTTING TECHNIQUE FOR VEGETATIVE PROPAGATION OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagati

11. SPRAY RETENTION ON COFFEE LEAVES ASSOCIATED WITH TYPE AND CONCENTRATION OF ADJUVANTS
ABSTRACT Agricultural spray adjuvants (ASA) are widely used in pesticide applications to enhance the performance of pesticides. The aim of this research was to investigate the effects of ASA on static surface tension (SST) and foliar spray retention on coffee leaves. The SST of ASA at different concentrations was determined by the drop weight method. Spray r

12. Does the Use of Adjuvants Alter Surface Tension and Contact Angle of Herbicide Spray Droplets on Leaves of Sida spp.?
RESUMO: O espalhamento das gotas sobre superfícies vegetais pode indicar melhor eficiência numa aplicação de herbicidas. Com este trabalho, objetivou-se avaliar a tensão superficial e o ângulo de contato de gotas do herbicida aminopiralide + fluroxipir associado a adjuvantes sobre a superfície foliar de três espécies do gênero Sida. O experimento f
