Plant adaptations to cope with shade may vary according to the degree of shade tolerance and nutrient availability for each species. Studies of diff erent understory species and their responses to combined shade and N eff ects are important to identify ways to optimize the quantity and quality of forage production. Our objective was to measure the dry matter yield (DMY) and nutritive value of six C4 grasses grown in two systems (full sunlight [FS] vs. a naturally shaded system composed of Eucalyptus dunnii Maiden trees) with two N levels (0 vs. 300 kg N ha?1yr?1) using the same target sward conditions (i.e., 50% depletion of the canopy height set by 95% light interception). Over 3 yr, the decreases in DMY under shade compared with FS ranged from 7% [Urochloa brizantha (Hochst. ex A. Rich) R.D. Webster] to 56% (Cynodon spp.) in fertilized treatments and between 11% (Paspalum notatum Fluegge) to 46% (Cynodon spp.) in treatments without N. Th e N eff ect was more important to the nutritive value of the forage than the shade eff ect, particularly for crude protein (CP, +46 g kg?1 with N supply), acid detergent fi ber (ADF, ?46 g kg?1) and leaf proportion (+11.2%). However, most of the species displayed higher leaf digestibility under shade due to decreases in ADF. Even with intense shading (light approximately 48% of unshaded), the digestible DMY and CP yield under trees were, on average, 70 and 71% of the 6.8 and 1.4 t ha?1 recorded in FS, respectively. |

The objective of this work was to evaluate the effect of different ackagings for the transportation of the Rama Forte persimmon (Diospyros kaki) cultivar on the sensory characteristics and consumer acceptance of the product during storage. Three types of packagings were evaluated: wooden crate; ardboard boxes; and a new packaging made of recycled polyethylene thermosinjected structure with 10% fodder fiber associated with a polypropylene tray, thermoformed in the exclusive design for persimmon. Check-all-that-apply (Cata) questions were used for the sensory characterization of fruits, revealing differences among samples throughout storage time regarding persimmon sensory attributes and consumer preference. Consumer acceptance of fruits from the wooden crate and cardboard box decreased from the first and fifth day onwards, respectively, as storage time progressed, differing from those from the new packaging, whose appearance was liked up to the ninth day. Persimmon transported in the new packaging showed superior quality throughout shelf life. The new packaging, with an appropriate design, maintains the sensory characteristics of persimmon for a longer time than the other studied packagings. |
