2. EFFECTS OF PHOTOSELECTIVE SHADE NETS ON EARLY GROWTH OF SUGARCANE SEEDLINGS
ABSTRACT Sugarcane has a great economic interest in Brazil, so it needs technologies to increase its yield strength, especially for seedling production. This study aimed to ascertain the influence of shading nets on early growth and development of pre-sprouted sugarcane seedlings. An experiment was conducted in a protected environment, in the Rural Federal U

3. Evapotranspiration and water sensitivity of Amazonian yellow ipe seedlings under different shading conditions
RESUMO A falta de informações técnicas sobre as exigências agroclimáticas e ecofisiológicas de espécies florestais, principalmente na fase inicial, limitam a produção de mudas de qualidade, o planejamento e a otimização de viveiros. Determinou-se a evapotranspiração, coeficientes de cultivo (kc) e os fatores de sensibilidade hídrica (ky) de mud

8. Microclimate alterations caused by agricultural hail net coverage and effects on apple tree yield in subtropical climate of Southern Brazil
ABSTRACT The use of hail net coverage on plants is an effective measure to mitigate damage caused by hailstorms. In southern Brazil, areas with apple orchards under hail net coverage have increased in recent years. However, little is known about the possible effects on the microclimate and, consequently, on plant growth, crop yield and fruit quality. The hyp
