Feeding ruminants in arid and semi-arid regions has always been a challenge for producers, due to the edaphoclimatic conditions in these regions. The cactus pear is configured as a strategic food resource used in animal feeding in the aforementioned regions, this forage has morphophysiological characteristics that give it adaptation, in addition to high acceptability by ruminants, the cactus pear is considered ...
Research with forage palm in semi-arid regions are driven by the importance of its production of juicy fruits and stems (cladodes), which guarantee a source of water and nutrients in quantity and quality for people and animals in these places. Recently, the search for natural substances, including secondary plant metabolites (MSPs), showed an expressive amount of these substances in the forage palm, with effec...
Allelopathy is an ecological mechanism that influences the development of neighboring plants. The objective was to evaluate the allelopathic potential of Cenostigma bracteosum and Sarcomphalus joazeiro on seed germination and initial growth of Mimosa caesalpiniifolia seedlings. Seeds of this species were placed to germinate on paper towel substrate, and then moistened with extracts from dry leaf of S. joazeiro ...
Cotton growing in Brazil is characterized by a great diversity of production systems, including modernization intense based in agribusiness from Cerrado region, beside small production centers directed to niche markets linked to family-based agriculture that is expansion process and structuring in the Semiarid Region. Thus, this study aimed to develop models based on NIR hyperspectral measurements for seed anal...
Objetivou-se neste estudo caracterizar os padrões alométricos da Copernicia prunifera em região semiárida do Rio Grande do Norte. O levantamento foi realizado em uma área rural do município de Lagoa de Pedras, RN. Foram amostrados todos os indivíduos adultos reprodutivos em uma área de 1,1 hectares, totalizando 33 plantas. As relações alométricas avaliadas foram entre: altura total x altura do fuste, CNS (circu...
Sterculia foetida é uma espécie florestal exótica com potencial para produção de biodiesel, porém pouco se sabe sobre sua propagação. O objetivo do trabalho foi caracterizar morfometricamente as sementes e avaliar a emergência e crescimento inicial de plântulas de Sterculia foetida, submetidas a diferentes concentrações de esterco bovino. Procedeu-se a instalação do experimento a partir do delineamento em bloco...
