RESUMO - O estudo desenvolvido neste trabalho foi estabelecido para determinar o efeito de população de plantas e espaçamento entre fileiras, sobre os componentes do rendimento por planta de soja submetida a irrigação em diferentes estádios de desenvolvimento. A irrigação durante o período vegetativo e o florescimento aumentaram o peso de 100 sementes. O número de legumes por planta foi superior na população de 250.000 plantas/ha, não diferindo entre população de 350.000 e 450.000 plantas/ha. Conforme se aumentou o espaçamento entre fileiras, houve decréscimo no rendimento por planta, no número final de plantas por área, no numero de legumes por planta e no número de sementes por legume. ABSTRACT - The study reported herein was designed to determine the effect of plant population and spacing between rows on yield componenta and yield por plant of soybean under irrigation in different development stages. Irrigation during vegetative and flowering periods increased the hundred-seed weights. The number Of pods por plant was higher in the population of 250,000 plants/ha, but there was no difference between the population of 350,000 and 450,000 plants/ha. The final number of plants per area, seed yield per plant, number of pods per plant and number of seeds per pod were decreased with increased row spacings. |

Piezodorus guildinii (Westwood) is a soybean pest that causes significant economic losses in the Americas. The variability of overwintering (diapause) traits was evaluated in populations of the Southwest (SW) (33°55′?34°17′S, 57°13′?57°46′W) during 2-year period (2011?2013) and of the Northwest (NW) (32°01′?33°02′S, 57°50′?57°24′W) during 1-year period (2014?2015) Regions of Uruguay. Samples were taken from different plant species (cultivated legumes, wild shrubs, and trees) and from overwintering sites (leaf litter and bark). Alfalfa, Medicago sativa L. was the main host, with a collection period of 10?11 months in the SW and 12 months in the NW. Cluster analysis for each sex was carried out to group the months according to the similarity in diapause traits of populations (body size, body lipid content, immature reproductive organs, and clear type of pronotum band and connexivum in females). Female diapause in the SWwas longer (beginning of autumn to end of winter) than that in the NW (mid-autumn to mid-winter). Male diapause was longer (mid-autumn o mid-winter) in SW1 (1st year) than in SW2 (2nd year) and NW (lateautumn to mid-winter). In both regions, male diapause was shorter than female. Differences were associated with maximum temperature at daylight hours ≤ 12.1, being necessary maximum temperatures below 23.8 °C for females and 19.2 °C for males to initiate diapause. |
