Com grande importância no Brasil, a cultura do milho ainda apresenta produtividade baixa, devido dentre outros fatores, à falta de cultivares adaptadas às regiões de cultivo emergentes. Desta forma, objetivou-se avaliar o desempenho agronômico e econômico de 16 genótipos de milho no per...
Leaf area is an important parameter in agronomic and physiological studies; thereby, the techniques used for its determination should be simple, fast and accurate. The objective of this study was to evaluate the efficiency of an equation for the indirect determination of leaf area&...
O objetivo dessa pesquisa foi realizar a avaliação econômico-financeira da soja, safra 2017/2018, na região norte do estado de Rondônia, Sudoeste da Amazônia. Foi conduzido um experimento na Unidade de Referência Tecnológica implantada no campo experimental da Embrapa em Porto Velho, Ro...
A inserção de plantas leguminosas pode representar uma estratégia para fertilização em solos distróficos na região amazônica. Objetivou-se avaliar o acúmulo de nutrientes, recalcitrância da palhada e o efeito de diversas plantas leguminosas sobre o status nutricional do milho em sucessão. Fo...
The presence of weeds on fields is a concern for farmers, due to competition with the commercial crops, reducing yields. The intercropping of maize with legumes provides weed control; after senescence, the nutrients accumulated by plants are released, recycling nutrients. The study of&#...
The intergenerational transfer of plant defense compounds by aposematic insects is well documented, and since 2006, has been shown for Cry toxins. Cry toxins are proteins naturally produced by the soil bacterium Bacillus thuringiensis (Bt) and its genes have been expressed in plants...
The cellular uptake of dsRNA after dietary exposure is critical for RNAi efficiency; however, the mechanism of its uptake in many insects remains to be understood. In this study, we evaluated the roles of the endocytic pathway genes Clathrin heavy chain (Chc), Clathrin adaptor ...
Correlations and path analysis allow the understanding of the interrelations between characteristics of interest to the plant breeding. However, in order for their results to be reliable, the undesirable effect of multicollinearity must be excluded. The objective of this study was to es...
tBacterial endophytes are considered to have a beneficial effect on host plants, improv-ing their growth by different mechanisms. The objective of this study was to investigatethe capacity of four endophytic Bacillus strains to solubilize iron phosphate (Fe-P), pro-duce siderophores and indole-ac...
