Mandioca tipo mesa cultivada com bioinsumos no município de Campo Alegre, Alagoas.

Abstract

Cassava (Manihot esculenta Crantz.), a perennial shrub belonging to the Euphorbiaceae family, can be classified according to the concentration of hydrocyanic acid into table and industrial types. Table-type cassava is widely cultivated in Alagoas, mainly in the rural region of the state.The demand for roots and aerial partsis growing. Producersseek modern, low-cost technologies to increase productivity and product quality. In this scenario, bioinputs emerge as a promising option. Therefore, the objective of the present work was to evaluate the productivity of the roots and shoots of a table-type cassava genotype, cultivated with the use of bioinputs. The study was conducted at the Santa Maria farm, in Campo Alegre, Alagoas, from October 2022 to June 2023, using a randomized block experimental design with six treatments and three replications. The treatments consisted of different doses of bioinputs (control, 150, 250, 350 and 500 mL of Biomaphos and 150 mL of Biotrophycus) sprayed on the seed plants of the Recife cultivar, planted in furrows with a spacing of 1,0 meter between rows and 0,60 meters between plants. The planting was irrigated. The evaluations were carried out at harvest, eight months afterplanting, covering the following characteristics: plant height, stem diameter, length and diameter of marketable roots, weight of marketable and non-marketable roots, weight of leavesand stems, determination of the content of starch, flour yield and cooking time. It was foundthat the different treatment doses did not affect plant height, stem diameter, root length, starchcontent, flour yield and cooking time. The 150 mL dose of Biomaphos contributed to greaterleaf productivity and total aerial part weight. Regarding root productivity, the application of250 mL of Biomaphos resulted in yields greater than 9 t ha-1compared to the 150 mL dose ofBiotrophycus.
