| Abstract The cowpea (Vigna unguiculata [L.] Walp) is of social and economic importance in developing countries. There are several factors that lead to low cowpea yields in tropical regions, such as pests and low technological development. This study aimed to identify and quantify losses in the critical component of production, and the key loss factors for three cowpea varieties (buttermilk, milk, and vinegar) grown in Santarém, Brazil, and inoculated or not with Bradyrhizobium japonicum. Crop life tables, loss factors, and production components of the three varieties were evaluated. Differences in yield and total losses were observed between varieties, but not between treatments with and without inoculant. In all three varieties, flowers were a critical... |

| O objetivo do trabalho foi conhecer algumas características biométricas, a produtividade e a renda bruta de quatro clones de taro cultivados em Latossolo Vermelho distroférrico de textura argilosa. Foram estudados os clones Macaquinho, Japonês, Chinês e Cascudo, no delineamento experimental em blocos casualizados, com seis repetições. As plantas dos taros Chinês e Cascudo apresentaram as maiores altura e massa fresca de folhas Os valores de diâmetro e comprimento dos RM, do diâmetro dos RF comerciais e do comprimento dos RF não-comerciais e as porcentagens de massas seca de folhas, RM e RF variaram entre clones. Os quatro clones estudados não apresentaram diferenças estatísticas nos valores de produção (t há-1) de massa fresca de rizomas-mãe (variação de... |

| Roots and shoots from seedlings of 29 coffee genotypes were studied to better characterize the entries from the Coffea germplasm bank of the Instituto Agronômico (IAC), Campinas, State of São Paulo, Brasil. The varieties were seeded in a randomized complete block design with 6 replications and 10 plants per plot. The characters evaluated were: plant (PL), shoot (SL) and root (RL) length; total plant (PDM), shoot (SDM), root (RDM) and lateral root (LRDM) dry matter. A lateral root index (LRI) and shoot root dry matter (SRDM = SDM/RDM) and length ratios; (SRL = SL/RL) were calculated. The dwarf varieties (Catuaí, Icatu-caturra, Vila Sarchi, San Ramon, Vila Lobos, São Bernardo) presented higher LRDM and lower SDM than the normal size varieties such as Mundo... |
