Evaluation of agronomic characteristics and productivity of elephant grass (pennisetum Purpureum schum) cv. Brs Capiaçu in different dosages of phosphate fertilization

Abstract

Elephant grass BRS capiaçu is a new cultivar in the forage area, having productive potential both in the form of silage and in chopped green form, however this plant requires good availability of phosphorus in the soil to obtain this productive potential, due to the P deficit. in soils and the lack of information about it,  given the need for new studies related to phosphorus and its productivity. The objective of this work was to evaluate agronomic characteristics and productivity at different levels of phosphorus (P) in elephant grass cv. BRS Capiaçu. The experimental design used was randomized blocks (DBC), with four treatments and four replications, totaling 16 experimental units. The treatments were composed of four doses of P2O5, T1=0, T2=100, T3=250 and T4=400 kg/ha. Each block contained 4 lines and 7 plants per line, with a spacing of 0.75 m between plants and 1 m between lines, totaling an area of 60 m2. The experiment was conducted in the agricultural experimentation area of the Centro Universitário Tocantinense Presidente Antônio Carlos – UNITPAC, in the municipality of Araguaína Tocantins between the months of October 2023 and June 2024.
