A mineração de cassiterita na mina Serra da Onça, localizada Floresta Nacional do Jamari, Estado Rondônia, causou profundas alterações físicas, químicas e biológicas nos solos. Em 1997, a área foi dividida em parcelas dado início um programa recuperação, que consistiu modelagem terreno, construção terraços, calagem, fertilização, plantio leguminosas espécies nativas. cada ano se sucedeu, foram instaladas novas para serem recuperadas, às quais aplicou o mesmo tal modo que, no momento...
Rice (Oryza sativa L.) stands out as a staple food of the world population due to important nutritional properties. However, rice physico-chemical parameters vary according genotype and management, for example, use nitrogen fertilizer.

O arroz ( Oriza sativa L.) destaca-se como alimento basico da populacao mundial devido suas importantes propriedades nutricionais. No entanto, as caracteristicas fisico-quimicas do grao de variam com a cultivar, podendo ainda ser influenciadas pelo manejo cultural, exemplo adubacao nitrogenada. presente trabalho teve por objetivo avaliar dos graos treze cultivares terras altas, sob irrigacao suplementar aspersao, submetidas diferentes doses nitrogenio (0, 40, 80, 120 e 160 kg ha-1) em...
Biofortification is a process in which plant species are improved order to raise the nutritional content of product consumed. The following some main techniques that can be introduced breeding programs improve quality food produced. rice for higher Fe and Zn grain, β-carotene folate used transformation, transformation via protoplasts, bioballistics (or biolistic), Agrobacterium tumefaciens, identification vitro selection transformed tissues, concepts gene expression regulation, protein...
Abstract Maize intercropping with forage crops and N under no‐tillage management have led to discrepant results regarding the impact on crop yield. Therefore, understanding various production systems is necessary assist producers in decision making. The aim of this experiment was evaluate whether maize ( Zea mays L.) Urochloa ruziziensis (R. Germ. C.M. Evrard) Crins promotes differences agronomic performance if split top‐dressing fertilization previous (common bean [ Phaseolus vulgaris L.])...
