| An experiment was conducted to evaluate the effect of plant spacing and nitrogen fertilization on Swiss chard's yield, from September to November 2009. The experimental design was of randomized blocks in split plot with four replications. In the plots were allocated the two plant spacings (0.30 and 0.50 m) and in the subplots the five doses of nitrogen (0, 40, 80, 120 and 160 kg ha-1). The crop was harvested 90 days after transplanting. The plant spacing of 0.50 m provided increased production of total fresh weight of shoot (961.7 g plant-1) and marketable (873.1 g plant-1). However, the highest total yield (77.8 t ha-1) and marketable (64.5 t ha-1) was achieved with the smaller spacing between plants (0.30 m). The N rates applied in coverage until 160 kg... |

| ABSTRACT The eggplant is a highly valuable horticultural crop grown all over the world and it is of substantial economic importance in Asia. However, its production is severely threatened by several soil-borne and foliar diseases, insect-pests, drought, heat, and frost damage. Therefore, efforts to transfer useful resistance genes into eggplant from their wild relatives is important. In the present study, interspecific and intraspecific hybridization was carried out, that included three cultivated genotypes of eggplant (Solanum melongena MEE, Solanum melongena MEP, Solanum melongena MEB) and one wild Solanum species (Solanum incanum INC). The F1 hybrids were made by inter and intraspecific hybridization. A total of 632 possible inter and intraspecific... |

| ABSTRACT Fertilizers supply in the appropriate period and dose is important to obtain satisfactory production. In this research we studied the effect of different split applications and doses of nitrogen in top dressing on the production of the carrot and the physicochemical characteristics of the roots. Nine treatments, resulting from a factorial of 4x2+1 (control without nitrogen fertilization), were evaluated in the randomized blocks experimental design, with four replications. The first factor were four nitrogen (N) doses in top dressing (60, 90, 120 and 150 kg ha-1) and the second were two forms of splitting [three equal applications (1/3+1/3+1/3 of the dose) and one with increasing proportions (1/6+2/6+3/6 of the dose) applied 15, 30 and 50 days... |

| The water consumption, crop coefficient and effective rooting depth of the peach palm cultivated in a Vertisol were evaluated over two years and three months, from planting to fifth harvest, in Juazeiro, Bahia State, Brazil. Plants were irrigated by microsprinklers under two irrigation treatments, full irrigation (FI) and reduced irrigation (RI), and the amount of water applied in RI corresponded to 75% of that of FI. Water consumption and crop coefficient has increased markedly at the first harvest (7.3 mm day-1 and 1.2, respectively, in FI treatment) in the thirteenth month, as a consequence of plant canopy development. After that, plants were harvested every three or four months, and these values varied a little due to decrease of the stand. The... |

| The production of scallion has been widely exploited on small farms, since it requires little care and is largely commercialized close to the production sites. Pink root, caused by Phoma terrestris (syn. Pyrenochaeta terrestris),is among the main diseases affecting this crop. However, little information on aspects related to yield and few cultivars resistant to the disease are available. In this study we evaluated these variables on Konatsu, Natsu and Nebuka cultivars. The experiment was carried out in Lontras, Santa Catarina state, Brazil, in a complete randomized blocks design with four replications. After 80 days of transplantation the following parameters were evaluated: plant mass, total and marketable number of leaves, total and marketable mass of... |

| Heart-of-palm, palm heart, or "palmito" can be considered as a non-conventional vegetable, largely consumed in Brazil and exported to more than sixty countries. Timing of heart-of-palm harvesting is a critical issue in palmito agribusiness, since it affects yield, quality and costs. A three-year field experiment was utilized to identify the correct timing for king palm heart-of-palm harvesting, from the standpoint of maximizing yield and minimizing growing period. The experimental site was located at Pariqueraçu, Vale do Ribeira, a region where palmito agribusiness has increased recently, due to adequate climatic conditions, low costs and high industry demand. Crop was grown in 2 x 0.75 m spacing, utilizing six-month old seedlings. Growth was assessed... |

| ABSTRACT In Brazil, studies on commercial exploitation of yacon are still scarce. A growing interest in this vegetable has demanded some researches on this crop cultivation management, though. Considering that yacon has a long cycle, which exposes the soil, studies on mulch management will be of great value. We used a randomized complete block design, with five replicates, under different soil mulches for yacon cultivation: two plastic film covers (black and double-sided), four mulches (corn husk, coffee husk in three levels), and the control (bare soil). Plastic mulch can be used for yacon cultivation, considering that the double sided plastic provides greater production of total roots; however, the same yield of the most valued roots was obtained using... |

| The purpose of this experiment was to analyze the effect of five irrigation water depths on oregano production. Oregano is a plant rich in essential oil, commonly used as seasoning in food preparation. The water depths were estimated based on the class A pan evaporation (CPE): 0 CPE (without water replacement); 25 CPE, 50 CPE, 75 CPE, and 100% CPE. The analyzed variables were fresh and dry weight of leaves and roots, yield, net return, and water use efficiency. The experiment was carried out in Presidente Prudente, São Paulo State, Brazil, from February to May 2006. The best results for all the studied variables were found when 100% CPE was used. A linear positive relation was observed between water increments and fresh and dry weight of both the... |
