SUMMARY:

Brazil is characterized as the largest charcoal producer in the world, a factor that boosts the sector. A product of the carbonization of wood, charcoal, also known in agriculture as biochar, is responsible for improvements in the most diverse aspects of soil and culture. It acts as a good soil conditioner, improves fertility and the development of the root part and its products. The pyroligneous extract is a by-product of the smoke collected during the carbonization process and has properties favorable to the development, rooting and protection against pests in the species. Cowpea is a variety widely produced and consumed in the country. Therefore, the present work aims to analyze the action of biochar and saneka mixtures (biochar + pyroligneous extract) on the development of cowpea (Vigna unguiculata (L.) Walp.), in two stages: green and dry. Furthermore, paying attention to the productivity levels, size, quantity and quality of the grains obtained. Seven treatments were used, one being a control, and the dosages were 3, 6 and 9 ton/ha of biochar and saneka. The treatments had eight replications each. Four seeds were planted, thinning the two least vigorous seeds after the first few weeks after emergence. The variables analyzed were: number of pods, pod length, grain size and weight, and root dry mass. The experiment data was collected after a period of three and a half months. After that, they were subjected to analysis of variance and the means were compared using the Tukey test. It was found that, for beans harvested green, the best treatment was 9 tons for all variables. As for beans harvested green, the most relevant treatment was the smallest, with 3 tons/ha having been applied to all the variables analyzed.
