Formulação de extrato aquoso de tremoço branco (Lupinus albus L.) adicionado de suco de pitanga utilizando metodologia de superfície de resposta

The aim of the present study was to verify, through the response surface methodology, the optimum conditions for the combined use of aqueous extract of white lupine (Lupinus albus L.) and tropical pitanga juice (Eugenia unifl ora L.) in the development of a drink. Therefore, the independent variables were represented by the volume of aqueous extract of lupine (mL) and by the volume of pitanga juice (mL). The dependent variables (responses) were obtained through sensory test of acceptance (“appearance”, “aroma”, “taste” and “overall acceptability”). The combined optimization of the variables pointed the second formulation (50mL of aqueous extract of lupine and 30mL of pitanga juice) of the experimental project as the most adequate. In conclusion it was possible to get a drink with attractive sensory characteristics using aqueous extract of white lupine and tropical pitanga juice. The usage of response surface methodology made possible the determination of regions of maximum acceptance for each attribute evaluated in the formulation of a drink with aqueous extract of white lupine and pitanga juice, with a minimum of tests.

Nitrogen management in maize cover crop rotations

Winter cover crops can affect N nutrition of the following maize crop. Although legumes have been recommend for maize rotations, in tropical areas grasses may be more interesting because they provide a longer protection of soil surface. Legumes can add N to the system and grasses can compete with maize for the available nutrient. An experiment was conducted in Botucatu, São Paulo State, Brazil, to study N dynamics in the soil surface straw-maize system as affected by N fertilization management and species included in the no-till rotation. Treatments were fallow, black oat (Avena strigosa), pearl millet (Pennisetum glaucum), white lupins (Lupinus albus), black oat fertilized with N. and pearl millet fertilized with N. Maize was grown afterwards in the same plots, receiving 0.0, 60.0 and 120.0 kg ha(-1) of N sidedressed 30 days after plant emergence. Soil, straw and maize samples were taken periodically. The highest corn yields were observed when it was cropped after pearl millet fertilized with N. Nitrogen side dressed application up to 120 kg ha(-1) was not able to avoid corn yield decrease caused by black oat. Grasses can be recommended in maize rotations in tropical areas, provided they receive nitrogen fertilizer and show no allelopathy. Due to its higher ON ratio and dry matter yield they are better than legumes, protecting the soil surface for a longer period. Pearl millet is particularly interesting because it enhances N use efficiency by the following maize crop. For a better N availability/demand synchronism, the cover crops should be desiccated right before maize planting.

Formas de fósforo no solo após o cultivo de braquiária e tremoço branco

Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ruziziensis) and white lupin (Lupinus albus L.). The study was carried out in a greenhouse at Botucatu, State of São Paulo, Brazil. Brachiaria and white lupin were grown in pots with soil fertilized with 0, 20, 40, 60 and 80mg dm-3 P. The plants were grown for 60 days, when they were harvested and the soil was sampled. Dry matter yields of both species were increased with P rates. Soil bioactive P is increased with P fertilization, but is not affected by the plant species. White lupin is more effective in taking up the organic soil P, but Brachiaria was more effective in reducing the soil maximum P adsorption capacity.

Nutrição mineral de plantas ornamentais XI: deficiências de macronutrientes e de boro em Catharanthus Roseus (L.) G. Don e Catharanthus roseus f. albus (sweet) G. Don

Plantas de duas formas botânicas de Catharanthus roseus, de flores lilases e de flores brancas foram cultivadas em soluções nutritivas deficientes em N, P, K, Ca, Mg, S e B, e em solução completa, a fim de se obter o quadro sintomatológico das deficiências, assim como os níveis analíticos de nutrientes nas folhas, caules, raízes e flores. Manifestaram-se sintomas de deficiência claros para todos os nutrientes estudados. Nas plantas de flores lilases, as concentrações de nutrientes na matéria seca de folhas de plantas normais e deficientes foram, respectivamente, para cada nutriente estudado: N(%): 3,53-1,20; P(%): 0,35-0,11; K(%): 2,45-0,76; Ca(%): 1,77-0,81; Mg(%): 0,55-0,46; S(%):0,21-0,12; B(ppm): 382-37. Nas plantas de flores brancas, estas concentrações foram: N(%): 3,78-0,92; P(%): 0,38-0,09; K(%): 2,60-0,86; Ca(%): 1,37-1,15; Mg(%): 0,56-0,44; S(%): 0,10-0,07; B(ppm):372-39.

TYPIFICATION OF LUPINUS-VILLOSUS WILLD (LEGUMINOSAE, PAPILIONOIDEAE)

The neotype of Lupinus villosus Willd., chosen on the suposition that the original collection had been lost during the destruction of the Berlin Herbarium (B) is rejected here. A lectotype is proposed based on the specimens of Willdenow's Herbarium (B-W), still extant.
