| ABSTRACT The objective of this study was to evaluate the energetic values of dry residue of cassava (DRC) and the effects of its inclusion in broiler diets on performance, intestinal morphometry, protein and fat deposition rate, and carcass and cut yields. In experiment I, two metabolism trials were carried out from 11-21 and from 31-41 days of age. The birds were distributed in a completely randomized design and DRC was included at levels of 10, 20, 30 and 40% in the basal diet. In experiment II, 980 male chicks were distributed in a completely randomized design with seven treatments (0; 2; 4; 6; 8; 10; 12% DRC) and seven replicates. DRC levels did not influence (p>0.05) the energetic values. From days 1-7, weight gain (WG) had a linear adjustment, and... |

| Este trabalho teve por objetivo avaliar o efeito da poda da parte aérea, realizada em três épocas distintas, sobre alguns parâmetros fitotécnicos da mandioca (Manihot esculenta Crantz). Todos os tratamentos foram plantados em outubro de 1991. Em 1992, efetuaram-se as podas da parte aérea em maio, julho e outubro. A testemunha foi conduzida sem poda. Em maio de 1993, todos os tratamentos foram colhidos. As produções da parte aérea na poda, foram alteradas pela quantidade de folhas. As produções fresca e seca das raízes e da parte aérea e o índice de colheita, foram modificados após a poda, em relação ao tratamento sem poda. O stand final e o número de raízes por planta, não foram alterados pela poda. |

| 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... |

| In this study, we estimate an output distance function in the context of a multi-output and multi-input production technology by stochastic frontier techniques. Unbalanced panel data for smallholder farms that grown cassava and other crops in Southwestern Nigeria covering 2006/07 to 2008/09 farming seasons is used for the analysis. The results show that the marginal rate of transformation (MRT) between “other crops” grown by the farmers and cassava produced relative to the output mix is negative and significantly different from zero. We observed also that increasing returns-to-scale as well as technical progress characterized cassava production in the region. Furthermore, fertilizer and pesticides are found to have significant substitution effects on... |
