Pear (Pyrus communis) is an economically important fruit crop. Drops in yield and even losses of whole plantations are caused by diseases, most importantly fire blight which is triggered by the bacterial pathogen Erwinia amylovora. In response to the infection, biphenyls and dibenzofurans are formed as phytoalexins, biosynthesis of which is initiated by biphenyl synthase (BIS). Two PcBIS transc...

Soil amendments (e.g., compost) require uniform incorporation in the soil profile to benefit plants. However, machines may not mix them uniformly throughout upper layer commonly explored by plant roots. The study focuses on using image texture analysis determine level of mixing uniformity following passage two kinds harrows. A 12.3-megapixel DX-format digital camera acquired images soil/expande...

ABSTRACT Most studies about soil organic carbon stock changes in the Cerrado (Brazilian Savanna) biome are either related to field data collected clayey Ferralsols or different land uses, as if they were equilibrium. This study aimed evaluate effect of tillage systems and crop sequences on yield, a sandy Ferralsol from Bahia, Brazil. The experimental design was randomized blocks, with four repl...
