The aims of this study were to evaluate the effects of shade in pineapple plant with cassava, on the yields of pineapple fruit sand cassava roots, on the morph-anatomical variation, damage by solar radiation and chlorophyll content of pineapple leaves. Pineapple plants were cultivated in plots comprising three parallel row sunder different shade conditions provided by cassava plants grown at various spacings within single rows located on either side of the plots. The experiment was of a randomized block design with five treatments (cassava spacings of 0.50, 0.75, 1.00 and 1.25 m and a pineapple monoculture) and four replications. Yields of fruits and roots, together with the morphological, chemical and histological characteristics of the "D" leaves of pineapple, were determined14 months after planting the pineapples plant. Data were submitted to analysis of variance with the Scott-Knott test or Friedman test (P< 0.05) and to regression analysis. Pineapple plants grown under the majority of shade conditions presented higher fruit weight and overall yield per hectare in comparison with plants grown in direct sunlight. The maximum productivities of pineapple fruit were achieved when cassava plants were spaced 0.75 m apart and, under these shade conditions, fruits were fully protected against burning by the sun. The ?D? leaves of shaded plants were longer and thicker, with higher content of chlorophyll a and total chlorophyll, reduced stomatal density and dimensions of stomatal pores, narrower guard cells, thinner aquiferous hypodermis, and reduced abaxial and adaxial epidermis. The yield of cassava roots per plant increased linearly with increasing distance between the plants, but the yield per hectare decreased with decreasing plant density.

Knowledge on apparent digestibility coefficients (ADC) is necessary to maximize the feed efficiency, thus lessening dietary nutrient and energy losses. This study tasks the determination of apparent digestibility of selected feedstuff to striped surubim Pseudoplatystoma reticulatum, a carnivorous, South American catfish of economic importance for fisheries and fish culture alike. Juvenile striped surubim (82.4 ± 17.7 g and 23.0 ± 1.6 cm) was distributed in 21 cylindrical, plastic cages (80 L), housed in seven 1000 L feeding tanks under constant water flow and aeration and conditioned to a two daily meals (20h00m and 22h00m) feeding regimen on a practical, reference diet (RD) (460.0 g kg -1 crude protein (CP); 19.23 kJ g -1 gross energy (GE)]. Test diets were obtained by adding of 1 g kg -1 chromium III oxide and 300 g kg -1 of one the following feedstuffs: fish meal (FM), meat and bone meal (MBM), poultry by-product meal, feather meal, blood meal, soybean meal, wheat bran, corn and corn gluten meal to the RD. After the last daily meal, fish were transferred to cylindrical, conical-bottomed aquaria (200 L) under aeration and continuous water exchange, coupled to refrigerated plastic bottles for faeces collection by sedimentation. Best ADC of protein (99.36%) and energy (86.25%) were recorded for poultry by-product meal and MBM, respectively, which are thus deemed ideal surrogate feedstuffs to FM in the formulation and processing of diets for striped surubim. |
