| Evaluate the behavior of commercial corn hybrids, with or without artificial inoculation of Stenocarpella. Maydis fungus was aimed by this work. Experiments were conducted along the harvesting periods of 2010/11 and 2011/12, in Guarapuava - PR. Treatments were evaluated in a factorial scheme 4x2, being four hybrids of corn (DKB245, DKB390Y, P30F53H and P30R50H) with and without artificial inoculation with fungus S. maydis. Delineation was in randomized full blocks in a factorial scheme. The following characteristics were evaluated, amount of rancid grains, weight of a thousand grains and yield of grains. Results evidenced hybrid DKB390Y with genotype more susceptible to fungus S. maydis independent of agricultural harvest and presence or not of artificial... |

| This study aimed to evaluate the performance of 46 maize lines (S4) obtained from crosses between the commercial hybrids Penta x P30F53 in topcrosses with the commercial simple cross hybrid Dow8460 (tester) and checks (hybrids Penta, P30F53, Dow8460 and Status). The grain yield was evaluated in two environments in Guarapuava, Paraná State, and the effects of genotype, environment and genotype x environment interaction were significant. The grain yield of the topcross hybrids ranged from 8,416 to 13,428 kg ha-1. The agronomic characteristics of the forage and the bromatological characteristics of the silage were evaluated in environment 1. The green mass yield of the forage ranged from 48,767 to 87,714 kg ha-1 and the dry mass yield ranged from 14,749 to... |

| The aim of this research was to evaluate vitreousness in commercial corn hybrids with flint and dent grains and to study the effect of this characteristic on agronomic behavior, nutritional value, and ruminal degradability of grains harvested in silage maturity. Twelve commercial corn hybrids were evaluated. They were divided in two groups (six with flint grains and six with dent grains). The experiments were conducted in two municipalities represented by Guarapuava and Laranjeiras do Sul, both in Paraná State. The harvest for the grain quality analysis was performed at ¾ of the milk line stage in the grain. The following characteristics were evaluated: grain yield, grain yield in silage maturity, vitreousness, ruminal digestibility of grain, neutral... |

| The aim of this study was to evaluate the effect of nitrogen fertilization with and without humic acid in barley cultivars on the export of nitrogen, phosphorus and potassium grains. The experiment was performed in the city of Guarapuava, PR, during the 2015 and 2016 growing seasons. The experimental design was in RCB in factorial 5 x 2, with the following sowing fertilization (kg ha-1): 0, 100 NPK, 100 NPK+HS, 250 NPK, 250 NPK+HS and two cultivars, BRS Brau and BRS Elis. The dose of 250 kg NPK with humic substance increased the nitrogen export to barley grains, with the highest levels occurring in the BRS Brau cultivar under favorable climatic conditions. Under favorable climatic conditions, the export of phosphorus to barley grains in the agricultural... |
