| ABSTRACT This study aimed to evaluate NPK formulations used in fertilization at sowing associated with and without humic substances (HS) in terms of the agronomic characteristics and grain quality for malt from the barley cultivars BRS Brau and BRS Elis, focusing on the agricultural years 2015 and 2016 in Guarapuava, PR. The experimental design was a randomized block, in a factorial 5 x 2 format, with five fertilizations: 0 kg ha-1 (control); 100 kg ha-1 of NPK; 100 kg ha-1 NPK + HS; 250 kg ha-1 of NPK; and 250 kg ha-1 NPK + HS, using two barley cultivars, BRS Brau and BRS Elis, replicated four times. The variables evaluated were hectoliter weight, grain yield, malt quality by means of sort 1, 2 and 3, and the protein percentage. The data evaluated were... |

| ABSTRACT The main objective of this study was to evaluate the agronomic characteristics of commercial maize hybrids with modern and old architecture, under the influence of nitrogen (N) as top dressing with different plant populations. Two independent experiments were conducted, one in the municipality of Guarapuava (reduced spacing = 0.45 m) and the other in the municipality of Laranjeiras do Sul (conventional spacing = 0.90 m), in the Paraná state, Brazil, in the 2012/2013 growing seasons. The experiments were set in a randomized block design, with three replicates, in a factorial scheme (6 x 3 x 3), corresponding to six maize hybrids (with modern and old architecture), three plant populations (60000, 75000 and 90000 plants ha-1) and three N doses as top... |
