“…Bergamaschi et al (2006) observed, from a ten-year field experiment in the city of Eldorado do Sul, RS, that total irrigation provided an increase of nearly 70% in maize yield compared with non-irrigated crops. Moreover, Vieira et al (2013) also found a significant increase in irrigated crops compared with non-irrigated plants.…”

-This study assessed the effect of different irrigation levels and plant densities on maize crops cultivated during the second season in the Western Border region of the State of Rio Grande do Sul. This work was conducted at the Federal Institute of Farroupilha -Alegrete Campus/RS -between January and June 2014. Treatments were arranged in a completely randomized 5 × 4 factorial design, with 3 replicates each. Irrigation of fixed amounts of water that were based on the evapotranspiration of the culture (Et c ): 0, 50, 75, 100, and 125% of Et c were applied at 5-day intervals. Four densities of plants were defined (4, 7, 10, and 13 plants m -2 ). We assessed number of maize ears per plant, number of grains per ear, aboveground dry matter, mass of 100 grains, harvest index, and grain productivity. The number of grains per ear, mass of 100 grains, and grain yield were influenced by irrigation levels. Plant density and water depth influenced the number of grains per ear, the mass of 100 grains, and grain productivity. The highest yield of winter maize grain was achieved with a combination of 13 plants per m -2 and an irrigation level of 100% of Et c . Specific densities of plants maximized the yield of maize at each irrigation level, demonstrating that choice of plant density is a critical variable in the second crop of maize, and significantly influences the components of production.

“…For plant height, the hybrid 2B810 had 23% higher plant population when compared to the hybrid with the lowest plant height (MG 580). Although the irrigation depths did not differ significantly for plant height, other studies indicate the importance of water management in this crop (Kappes et al, 2011;Agostinho, 2011;Vieira et al, 2013). Rosa et al (2015) studied the behavior of 50 maize hybrids in response to two fertilization levels and verified mean heights of 213.1, 215.6, and 226.0 cm for hybrids DBK290, 2B810, and AS1633, respectively, in the region of Lucas do Rio Verde, MT, Brazil (Table 3).…”

This study aimed to verify the incidence of Fusarium spp. in commercial maize hybrids and irrigation management strategies utilizing center pivot systems. The experiment was carried out during the second season in a randomized block design with a split-plot arrangement with five maize hybrids (2B810, MG580, AS1633, DKB290, and AG8544). The plots were irrigated with five frequencies (1, 2, 3, 4, and 5 days) in one experiment, and five water depths (at 25, 50, 75, 100, and 125% of crop evapotranspiration) in another experiment. Plant height, ear insertion height, moisture at harvest time, yield, and incidence of stalk rot were evaluated. Neither irrigation frequency nor irrigation depth influenced the incidence of disease. The one-day irrigation frequency provided the highest yield for maize hybrids. Hybrid 2B810 showed the highest yield and the lowest incidence of the disease.
