ABSTRACT.- Apple pedestrian system allows performing all cultural practices from the ground and allows the mechanization of some practices such as thinning and pruning. The objective of this study was to evaluate the performance of different training systems in a pedestrian orchard. A trial with ?Gala Baigent? (Brookfield®) apples was installed at INIA Las Brujas, Canelones, Uruguay, in 2014/2015 growing season. Five training systems were evaluated:one leader/spindle, three and four leaders, guyot (around 5 leaders), and horizontal palmette. Trees were grafted onto ?M.9 NAKB T337?
ABSTRACT.- Soybean plants that express various insecticidal proteins of the bacterium Bacillus thuringiensis have been widely adopted globally in many crop systems. This technology effectively controls the main defoliating pest species in most countries and reduces insecticide spray requirements. However, widespread use of Bt crops also generates high selection pressure against pest populations, leading to resistance concerns. Refuge areas are established to delay this phenomenon, but little is known about their other ecological functions.

ABSTRACT.- This study aimed to estimate prediction ability and genetic parameters for residual feed intake (RFI) calculated using a regression equation for each test (RFItest) and for the whole population (RFIpop) in Nellore beef cattle. It also aimed to evaluate the correlations between RFIpop and RFItest with growth, reproductive, and carcass traits. Genotypic and phenotypic records from 8354 animals were used. An analysis of variance (ANOVA) was performed to verify the adequacy of the regression equations applied to estimate the RFItest and RFIpop.
