ABSTRACT Intensive conventional tillage cultivation of both green and sweet corn can contribute to soil degradation when compared no-till systems. This study aimed assess the agronomic characteristics physicochemical quality grains grown under succession planting using different cover crops. Two experiments were conducted, one with other corn, a randomized block design consisting seven treatmen...

Invasive exotic grasses are among the biggest obstacles to success of reforestation projects. The aim this study was evaluate efficiency crowning with cardboard in suppressing Urochloa humidicola and Megathyrsus maximus aiming its use areas. A field experiment installed a completely randomized design two treatments consisted without (control). caused progressive reduction biomass effective caus...

The forage grasses are explored for the phytoremediation of heavy metals from contaminated areas. The present study evaluates the tolerance of forages grasses to Pb and the availability of Pb for the Mehlich 1, DTPA, and USEPA 3051 and 3052 extraction methods. The forage grasses cultivars Panicum maximum cultivars Aruana and Tanzânia, Brachiaria decumbens cultivar Basilisk, Brachiaria brizantha...

The present study aimed to evaluate the effects of agroforestry system on the feeding behavior of dairy cows in the Brazilian Amazon region. Nineteen cross breed dairy cows (14.0±3.30 kg/d of milk yield and 450±40.1 kg body weight) were used. The following treatments were evaluated: A) animals were maintained in opened pasture of Brachiaria brizantha during all the day; B) animals were...

A pastagem constitui um dos alicerces na produção de carne e o seu adequado manejo se torna substancial garantia excelência da atividade. O crescimento gramínea forrageira está diretamente relacionado às propriedades físicas químicas do solo em que é cultivada. Mediante isto, presente estudo aborda sobre características produtivas estruturais Brachiaria ssp. Latossolo Vermelho-Amarelo. Os resul...

We used two hyperspectral sensors at two different scales to test their potential to estimate biophysical properties of grazed pastures in Rondônia in the Brazilian Amazon. Using a field spectrometer, ten remotely sensed measurements (i.e., two vegetation indices, four fractions of spectral mixture analysis, and four spectral absorption features) were generated for two grass species, Brachiaria...
