| The widespread adoption of cropping systems that are sustainable and environmentally friendly is vital for the macroeconomic survival of civilization. Intercropping could ensure stability of insect populations in a system. A 3-yr (2005-2007) field trial was therefore carried out in Nigeria under regular and ratoon crops to evaluate five recently developed pigeon pea (Cajanus cajan [L.] Huth) genotypes (ICPL 87, ICPL 161, ICPL 85063, ICP 7120, and ICPL 87119) from the International Crops Research Institute for Semi-Arid Tropics (ICRISAT) and one local variety for their relative performance and susceptibility to insect pests. The pigeon pea genotypes were in a mixture with two maize genotypes (Zea mays L., open-pollinated and hybrid) in regular crops for 2... |

| ABSTRACT We aimed to determine an adequate planting density and arrangement for the mechanized spraying of vertically staked tomatoes. Two experiments were carried out in the 2013/14 and 2014/15 harvests in the city of Calmon, state of Santa Catarina, Brazil, both in randomized block design. In 2013/14, treatments were arranged in a 4x2 factorial, corresponding to four planting densities (10,753, 12,903, 16,129 and 21,505 plants/ha) and two planting arrangements (single and double rows). In 2014/15, treatments were arranged in a 5x2 factorial, corresponding to five plant densities (the same planting densities of the previous harvest beyond 32,258 plants/ha) and the same planting arrangements. Total, marketable (considering extra AA and extra A fruits as... |

| The objective of this work was to study the yield performance and to determine the gross income of arracacha (Arracacia xanthorrhiza Bancroft), cultivar Amarela de Carandaí, grown in monoculture as well as in intercropping with the Japanese bunching onion (Allium fistulosum L.), cultivar Todo Ano (A-JBO) and parsley (Petroselinum crispum (Mill.), cultivar Lisa Preferida (A-P). Arracacha and the Japanese bunching onion were vegetatively propagated, while parsley was propagated by seeds. The Japanese bunching onion was first harvested 87 days after the planting (DAP), with resprouts harvested 154 and 212 DAP. Parsley was first harvested 105 days after the sowing (DAS), and, resprouts, 171, 212, and 268 DAS. Arracacha was harvested 268 DAP. At the harvest... |

| Em um Latossolo Vermelho da região do Cerrado, representativo de grandes áreas de cultivo de soja [Glycine max (L.) Merr.] e milho (Zea mays) no Brasil, os efeitos imediato e residual do P, aplicado nas doses de 0, 218 e 436 kg de P ha-1, em 2003, foram quantificados através de três diferentes tecnologias e estratégias envolvendo as culturas do milho e da soja em rotação: (1) Genética do milho, incluindo diferentes cultivares; (2) Sistema Santa Fé - Milho consorciado com braquiária; e (3) Inoculação de microrganismos. Os experimentos foram conduzidos no período de 2003 a 2014, na área experimental da Embrapa Milho e Sorgo, Sete LagoasMG. Verificaram-se, ao longo desse período, decréscimos acentuados na ?biodisponibilidade? de P residual (extrator Mehlich1)... |
