Nas últimas décadas do século XX, atenção especial passa a ser dada aos processos de geração, difusão e uso de conhecimentos. Diversos enfoques analíticos e normativos têm sido desenvolvidos visando entender e orientar esses processos. Este artigo objetiva apresentar e discutir os conceitos e sistema de inovação, suas vantagens e desafios, assim como examinar a experiência brasileira na sua utilização e no seu desenvolvimento. Em seu final, o artigo retoma as principais conclusões da análise realizada, destacando: (i) a prioridade de estimular e desenvolver os sistemas produtivos e inovadores mobilizadores do desenvolvimento social-como os de saúde; (ii) a urgência em avançar na compreensão das possibilidades de desenvolvimento dessas áreas, assim como na formulação de políticas que orientem e dinamizem esse desenvolvimento de forma sistêmica e sustentável.

This trial was performed at Bonilla Farm, plot 4, owned by Agroindustrial Los Prados, in San Jerónimo village, Namasigüe, Choluteca, southern Honduras, from late March to mid-May 2021. Harper melon, Capaz hybrid, by Enza Zaden, was transplanted on March 17 and covered with agribon or thermal cloth. Right in front of this planting area was a plot of Harper Melon being harvested with lots of weeds and a huge population of whiteflies constantly moving from that plot and also from abandoned watermelon plots located upwind, in East direction.

The present study reports the effect of the nanotechnology molecule “Nano Gro” on a number of agronomical variables of okra, Abelmoschus esculentus, as well as its effect on leaf miner, white fly, Bemisia tabaci, and Spodoptera larvae attacking the crop. Most initial data was taken in a trial used for the registration of Nano Gro as an agricultural amendment in Honduras, carried in a plot worked by Juan Benito Guevara, a local okra producer farming in Las Bazas, very near the city of Choluteca, next to the Choluteca river, in Southern Honduras. However, other important data was taken on plots from different local okra companies and producers in the Choluteca area. The stimulant Nano Gro is a mixture of sulfates and elements such as Fe, Co, Al, Mg, Mn, Ni and Ag, produced at a concentration of 10-9 mol, available in the form of an oligosacharid pellet. It has OMRI certification and can be used in organic and regular agriculture. According to the Honduran distributor (Núcleo Agro), Nano Gro stimulates the plant´s natural resistance to abiotic stress, which in turn makes the plant produce growth hormones like auxins, gibberellines and cytokinines. This hormone productionmakes the use of nutrients and water more efficient, resulting in greater plant resistance, greater performance and greater quality of fruit harvested.
