No. of bitstreams: 0 Previous issue date: 2021-01-01 Federal University of Piaui This study aimed to evaluate the agronomic parameters and the chemical composition of the cactus pear variety Doce (Nopalea cochenillifera) in different Brazilian savannah localities, subjected to different nitrogen fertilization strategies. A randomized block design was used in this experiment, with a 2x 4 x 2 factorial arrangement with five replications. The factors corresponded to two application frequencies of nitrogen fertilization (30 days and 30/60 days), four nitrogen doses (0, 100, 200, 400 kg ha(-1) year(-1)), and two cactus pear cultivation localities, with Locality 1 corresponding to the municipality of Curimata and Locality 2 corresponding to the municipality of Riacho Frio. After one year of cultivation, there was no interaction (P>0.05) for frequency x doses x locality, doses x locality, and frequency x doses. The means observed for fresh and dry matter production varied from 57.0 to 68.0 +/- 2.9 t ha(-1) and from 2.4 to 3.7 +/- 0.2 t ha(-1), respectively. There was an interaction (P |
