| This study aimed to quantify and compare water balance components over the course of a year for different Pinus taeda planting densities in an oxisol in southern Brazil. This experiment was conducted on 6-year-old trees in a clay oxisol at the Monte Alegre Farm, a property of the Klabin Company. The experimental design was a randomized block with four replicates and five treatments with different amounts of soil coverage: T100 (100% coverage - standard planting coverage); (T75, 75; T50, 50; and T25, 25%), and; T0 (without cover - clearcutting). The soil water storage and actual evapotranspiration under non-standard conditions were determined in a weekly estimated soil water balance (SWB) with measured components. By the end of the year, the treatments had... |

| The present work had the objective of evaluating the effect of different line spacing upon some agronomic parameters of cassava (Manihot esculenta Crantz) culture. The experiment was conducted in county of Palotina, in the west region of Paraná State, Brazil. The studied spacing were 0.8, 1.0, 1.4 e 1.6 m between lines and 0.6 m between plants, which rendered population densities of 20,830, 16,660, 13,880, 11,900 and 10,410 plants/ha. For the production of fresh and dry root matter and stem fresh matter, the best space between lines was 1.0 m. The highest number of tuberous roots per plant, obtained with the space of 1.40 m between lines did not guarantee the highest productivity of root matter/ha. The production of the vegetative portion was not... |

| The influence of plant population (31,250 and 46,875 plants ha-1) and nitrogen doses (0, 100, 200, and 300 kg ha-1) on the accumulation of macronutrients by cabbage plants was studied in Jaboticabal, Brazil, from February 18 to June 2, 2004. The experimental design was a randomized complete block in a 2 × 4 factorial scheme, with three replications. Differences in the amount of macronutrients accumulated by cabbage as function of N dose and plant population, were observed. The largest amounts of macronutrients were detected at the end of the plant cycle when the plant population was the lowest. The amounts of N, P, K, and S were not significantly different when the N dose was increased from 100 to 300 kg ha-1. The accumulated amounts of Ca and Mg were not... |
