History, projects and research


Parnaíba Farm started in the 80s in a shed, where the cotton gin is currently located. In 1994, it planted cotton as an experiment, which was harvested by hand. In 2000, it began with a crop of 50 ha. Today, the Farm has three headquarters, a Cotton Processing Unit and a Grain Processing Unit. The Unit has headquarters in the municipality of Tasso Fragoso (MA).


Social projects

Volunteers from Parnaíba Farm (MA) started a project to encourage reading and writing at the Escola Ana Alves de Araújo Morais, located in the Paraíso community, in Tasso Fragoso (MA). The goal is to motivate and encourage students to make reading a habit and consequently improve writing. The project includes a writing and drawing contest in addition to weekly lectures.


Parnaíba Farm has an area of approximately 125 ha for field tests where the behavior and response of agricultural crops to crop treatments are assessed, in addition to phytotechnical tests assessing adaptability and stability of genotypes. Studies of nutrition, pest control, diseases and weeds have also been carried out.
