| 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... |
