15. Estudo comparativo de respostas da banana Ãs aplicaÃÃes de fertilizante mineral e biofertilizante na Chapada do Apodi - CE / Comparative study on the responses of the banana to mineral fertilizer and biofertilizer applications
The liquid biofertilizers have been used with relative success in the recovery of banana plantations that have low productivity due to long time of cultivation. The area of the present study needs further investigations because there is little information available related to the cultural practices that could increase the time of the crop yield. The objectiv

16. Respostas de plantas de feijÃo-de-corda à aplicaÃÃo de biofertilizantes via foliar, sob condiÃÃes de baixa e alta salinidade / Responses of cowpea plants foliar application of biofertilizers, under salinity conditions.
Diante da necessidade de se buscar altas produtividades e menores custos em Ãreas salinizadas, o uso de fertilizantes orgÃnicos vem sendo muito utilizado na agricultura, como à o caso do biofertilizante bovino, entretanto estudos mostram que sua utilizaÃÃo, como minorador dos efeitos adversos da salinidade, vem sendo pouco estudada. Objetivou-se com ess

20. Agricultura de base ecológica em sistemas urbanos: potencialidades, limitações e experiências.
ABSTRACT: Urban agriculture conducted with ecological principles is an alternative to produce healthy food, but it demands planning and suitable technologies. This ecological approach must be based on crop diversity, organnic or mineral fertilizers from natural origin and control of pests and diseases by non-toxic means. Cultivation of different species is t
