“…Pereira et al (2007) evaluated the nutritional quality of maize silage and found no difference for the variables mineral matter and ethereal extract. Pinto et al (2010) found for ether extract, 4.80%, which is close to the value found in this study.…”

“…These values are lower than those found by Pinto et al (2010), which ranged from 49.1 to 56.2%. Gomes et al (2004) evaluated the characteristics related to maize silage productivity and observed that the correlations of NDF and degradation were negative in most cases.…”

“…Table 2 -Productivity of silages from corn hybrids lower than those found by Pinto et al (2010), who evaluated twelve cultivars of corn intended for silage production and found CP concentration between 7.1 and 8.8%. Also the mineral matter and the ethereal extract contents did not differ between the hybrids studied (P>0.05) and showed, respectively, the following average values: 3.68 and 4.09%, based on DM.…”

“…However, the hybrid with the highest plant height (SHS4070) also showed higher height of ear insertion, although it was not significant. Pinto et al (2010), leading a study on evaluation of maize for silages, in which 12 cultivars were tested, found variations in plant height between 1.82 and 2.47 m, positively correlating with dry matter production ranging between 17.10 and 18.10 t/ha. Rose et al (2004), evaluating the agronomic performance of maize plants and the silage nutritional value, found height of 1.84 m and dry matter yield of 12.48 t/ha for hybrid AG-5011.…”

-The objective of this research was to identify the potential of maize hybrids for the production of silage.Hybrids 1671B, 2B433, 20A78, SHS4070, BX1280 and DKB390 were tested in a randomized block design with three replications. The hybrids yields were evaluated (average plant height, height of ear insertion, number of broken and lodged plants/ha, leaf:stem and ear:plant ratio and production of of DM, CP and TDN/ha). There was no difference between hybrids for the variables studied, except for the height of ear insertion. With respect to chemical characteristics, N-NH3/NT organic acids, and pH, there was also no difference between cultivars and hybrid silages are rated as of very good quality.

“…De acordo com Oliveira et al (2010), essa utilização dos híbridos de milho constitui um dos fatores responsáveis pelo aumento da produtividade na cultura. No entanto, com o aumento da oferta de híbridos no mercado nacional, crescem as incertezas do agricultor quanto à escolha correta dos híbridos (SILVA et al, 2015).…”

Resumo: Uma das formas de maximizar a produtividade de grãos de milho é a escolha correta do híbrido para condições edafoclimáticas regionais. Nesse contexto, objetivou-se avaliar o desempenho agronômico de onze híbridos de milho na região sudeste de Goiás, Brasil. O experimento foi conduzido a campo, na safra (primavera-verão) 2013/2014, em Latossolo Vermelho distrófico sob condições edafoclimáticas do Cerrado, na região sudeste de Goiás. O delineamento experimental utilizado foi o de blocos ao acaso, sendo 11 tratamentos representados pelos híbridos de milho, com quatro repetições. Foram avaliados o estande final de plantas, número final de espigas, características morfológicas das plantas (altura da planta, altura da espiga e diâmetro do colmo), componentes da produção (comprimento da espiga, número de fileiras por espiga, número de grãos por fileira, número de grãos por espiga e massa de 100 grãos) e a produtividade de grãos. O estande final de plantas e o número de espigas foram semelhantes entre os híbridos. Os híbridos comerciais de milho apresentam grande variação no desempenho agronômico na região sudeste de Goiás. Com relação à altura das plantas e da espiga, os híbridos LG6036 e 20A55 apresentaram as maiores alturas de plantas e o híbrido LG6036 apresentou maior altura de espiga. Já, para o diâmetro do colmo, as plantas dos híbridos Feroz, BX1293, LG6036, 20A55, Maximus e P3862 apresentaram colmos grossos. Na avaliação dos componentes da produção, os híbridos de milho demonstraram variação nos resultados. Os híbridos simples Maximus e P3862, e os triplos 20A55 e 30A95 foram os mais produtivos.

Zea mays L.Abstract: One way to maximise grain yield in maize is the correct choice of hybrid for soil and climatic conditions in the region. The aim therefore was to evaluate the agronomic performance of eleven maize hybrids in the southeast of the State of Goias, Brazil. The experiment was carried out in the field during the 2013/2014 crop (spring-summer), in a dystrophic Red Latosol, under the soil and climatic conditions of the Cerrado in the southeast of Goias. The experimental design was of randomised blocks, with 11 treatments represented by the maize hybrids, with four replications. Evaluated were the final plant stand, final number of ears, morphological characteristics (plant height, ear height and stem diameter), production components (ear length, number of rows per ear, number of grains per row, number of grains per ear and 100 grain weight) and grain yield. The final plant stand and number of ears were similar between hybrids. The commercial maize hybrids showed great variation in agronomic performance for the southeast of Goias. For plant and ear height, the hybrids LG6036 and 20A55 had the greatest plant heights, and the hybrid LG6036 had the greatest ear height. For stem diameter, the plants of the Feroz, BX1293, LG6036, 20A55, Maximus and P3862 hybrids had thick stalks. With evaluation of the produc...
