The objective of this trial was to evaluate two intervals of grazing on elephant grass (Pennisetum purpureum Schum.) pasture. It was tested a variable grazing interval when it was observed an interception of 95% of active photosynthetic radiation by sward, and a 26-day fixed grazing interval. The experimental design was a complete randomized design with time repeated measurements. The interval of grazing, pre and post grazing sward heights, sward interception of active photosynthetic radiation and leaf area index were greater […]

The objective of this research was to describe comparatively the dynamics of herbage accumulation in Xaraés palisadegrass pastures [Brachiaria brizantha (A. Rich.) Stapf cv. Xaraés] submitted to rotational stocking managements, defined either by pre-graze light interception (LI) by the canopy (95% or 100% LI) or calendar days (28d). Pre-graze forage mass (FM) was higher for 100% LI pastures. Pastures grazed at 95% LI and 28-d resulted in similar pre-graze FM in the spring, both lower than that of the 100%-LI […]

The objective of this research was to quantify morphological responses of Tanzania grass (Panicum maximum Jacq. cv. Tanzania-1) under three grazing intensities in an irrigated, rotationally stocked setting. Treatments consisted of three grazing intensities represented by three post-graze forage masses (T1=1,000; T2=2,500, and T3=4,000 kg green dry mass/ha), in a randomized complete block design with four replications. During the grazing season (eight 36-d cycles; three days of grazing followed by 33 days rest), the following measurements were taken: mean sward […]
