O açaizeiro é uma palmeira de grande importância para a região amazônica, pois produz frutos que são amplamente consumidos através do processamento da polpa, e com isso, tem-se grande potencial de expansão em cultivos comercias, haja vista que a produção é basicamente do tipo extrativista. O objetivo deste trabalho foi avaliar o crescimento de açaizeiro solteiro (Euterpe precatoria) em consórcio com bananeira em Rio Branco, AC. O experimento foi instalado e conduzido no campo experimental da Embrapa Acre. O delineamento utilizado foi em blocos casualizados completos com quatro repetições e oito plantas por parcela. Os tratamentos foram assim dispostos: T1 - Açaizeiro em 4 x 3 m; T2 - Açaizeiro (3 x 4 m) com bananeira (3 x 2 m); T3 - Açaizeiro (3 x 4 m) com bananeira (3 x 3 m); T4 - Açaizeiro (6 x 3 m) com bananeira (4 x 2 x 2 m); T5 - Açaizeiro (4 x 2 x 3 m) com bananeira (4 x 2 x 2 m). Avaliou-se à altura, diâmetro do estipe e da copa e número folhas, a cada dois meses, e o vigor e a sobrevivência na última avaliação, aos 360 dias após o transplantio. O açaizeiro apresenta melhor crescimento em altura e diâmetro do estipe, e maior número de folhas emitidas em sistema de monocultivo até os 360 dias após o transplantio. Porém, em cultivo consorciado o vigor e a sobrevivência das plantas são maiores. Em cultivos consorciados, o açaizeiro apresenta comportamento semelhante quanto ao crescimento até os 360 dias após o transplantio. The assai is a palm tree of great importance for the Amazon region, because it produces fruits that are widely consumed through the processing of the pulp, and with this, there is great potential of expansion in commercial crops, since the production is basically of the type extractivist The objective of this work was to evaluate the growth of single assai (Euterpe precatoria) in consortium with banana tree in Rio Branco, AC. The experiment was installed and conducted in the experimental field of Embrapa Acre. The experimental design was a randomized complete block with four replicates and eight plants per plot. The treatments were thus arranged: T1 - Assai in 4 x 3 m; T2 - Assai (3 x 4 m) with banana tree (3 x 2 m); T3 - Assai (3 x 4 m) with banana tree (3 x 3 m); T4 - Assai (6 x 3 m) with banana tree (4 x 2 x 2 m); T5 - Assai (4 x 2 x 3 m) with banana tree (4 x 2 x 2 m). The height, diameter of the stipe and crown and number of leaves were evaluated every two months, and vigor and survival at the last evaluation, at 360 days after transplanting. The assai presents better growth in height and diameter of the stipe, and greater number of leaves emitted in monoculture system until the 360 days after the transplanting. However, in intercropped cultivation the vigor and survival of plants are greater. In intercropped crops, the assai shows similar growth behavior up to 360 days after transplanting.

Three field experiments were carried out in 1997/1998, 1998/1999 and 1999/2000 to investigate the relationship between severity (S) of alternaria leaf spot, caused by Alternaria helianthi, area under disease progress curve (AUDPC), healthy leaf area index at any given day (HLAI), healthy leaf area duration (HAD), radiation intercepted by healthy leaf area at any given day (HRI), total healthy leaf area absorption (HAA), and yield components of sunflower sown on four dates. AUDPC showed a relationship with yield in two years, following the negative exponential model coefficient of determination (R2 = 0·79 and 0·60). The HAD?yield relationship was linear for each of three trials (0·73 < R2 < 0·83). Among the integral variables analysed, the HAA?yield relationship was the best, fitted by the exponential model (0·77 < R2 < 0·89). Single-point models using disease severity, HLAI and HRI to estimate yield at various times during the crop season were tested. The slope of the severity?yield relationship was stable from the R1 (inflorescence visible) growth stage. The HLAI?yield relationship was stable between R1 and R6 (anthesis completed) and increased from the R7 (first phase of achene development) stage. The HRI?yield relationship was variable and not stable. The relationship between severity and yield in the R3 (second phase of inflorescence elongation) growth stage proved that plants with disease severity higher than 10% had yield lower than 500 kg ha1, regardless of the sowing date. This value can be used as a damage threshold for the disease. Disease severity can be used as an independent variable in a sunflower?-alternaria leaf spot management system and can be used to produce recommendations at the research level, such as genetic breeding for disease resistance or studies on sowing date.
