“…The ear diameter causes an increase in the number of grain rows per ear and consequently increases the number of grains per ear, resulting in higher grain yield (Homayoun, 2011). According to Edwiges et al (2017), the presentation of specificities for each hybrid analyzed occurs because they are commercial hybrids that have traits defined in the plant breeding program of each company.…”

Objetivou-se com a pesquisa avaliar os caracteres agronômicos e produtivos de híbridos de milho em dois locais. O delineamento experimental utilizado foi de blocos casualizados em esquema fatorial 11x2 (11 híbridos e dois locais) com quatro repetições. Cada parcela foi constituída por quatro linhas de cinco metros. As avaliações ocorreram nas duas linhas deixando 0,50 m de bordadura nas extremidades. As variáveis analisadas foram: altura de planta, altura da primeira espiga, diâmetro da espiga, número de fileira de grãos, número de grãos por fileira, comprimento da espiga, massa de mil grãos e produtividade. Os híbridos de milho se adaptaram melhor no município de Santa Isabel. Em relação a produtividade, no município de Santa Isabel os híbridos apresentaram mais adaptados e em Campinorte o híbrido MG 711 PWU foi que obteve melhor desempenho. O hibrido MG 580 PWU apesentou o pior resultado para os dois locais.

“…The means of EH (Table 4) ranged from 83 to 148 cm, and the cultivars were divided into two groups of means under low P and four groups in high P. Exceptfor cultivar PR 27D28 which did not differ in the two trials, the cultivars presented higher values of AE in high P. According to Edwiges et al [23] and Kopper et al [24], there is a positive correlation between PH and EH, that is, generally taller plants also have higher ears.…”

Aims: The research was carried out to evaluate the agronomic performance of corn cultivars in contrasting phosphorus environments in the state of Pará, Brazil. Study Design: The experimental design was randomized blocks with ten treatments and three replications. The treatments were composed of ten cultivars: AG 1051, AG 8088PRO2, BR 206, BRS 3046, PR 27D28, 2B655PW, AL BANDEIRANTE, ANHEMBI, CATIVERDE 02 and ORION Place and Duration of Study: In the 2017/18 crop, two competition trials of corn cultivars were carried out at Sítio Vitória, municipality of Santa Maria das Barreiras, state Pará, Brazil. Methodology: Two competition trials of corn (Zea mays L.) cultivars were carried out under contracting conditions of phosphorus: high P (100 kg ha-1 of P2O5) and low P (50 kg ha-1 of P2O5), using simple superphosphate (18% P2O5) as the source. The agronomic efficiency of phosphorus use was obtained by the difference between grain yield in both levels, divided by the difference between doses. The variables evaluated were: ear height, plant height, ear diameter, number of rows per year, number of grains per rows and grain yield. Results: The mean grain yield of the cultivars ranged from 5,446 kg ha-1 (low P) to 11,486 kg ha-1 (high P), and the means of all cultivars were higher in high P. The means agronomic efficiency ranged from 25.1 kg kg-1 (AL BANDEIRANTE) to 96.6 kg kg-1 (AG 1051). Conclusion: The highest phosphorus dose (100 kg ha-1 of P2O5) resulted in higher values in the variables studied. The cultivars that stood out the most, under high and low phosphorus, were AG 8088PRO2, AG 1051 and BRS 3046, the last two being agronomically efficient.

“…On the other hand, temperatures were normal and ranged from 8 o C to 34 o C in 2019 and from 16 o C to 33 o C in 2020 during the maize-growing period. Considering that temperature in the maize crop must vary between 10 o C and 35 o C for its optimal development (Edwiges et al, 2017), the plants were expected to have a good development.

One of the bottlenecks for maize (Zea mays L.) production is the need for a large supply of nitrogen fertilizers, which burdens farmers. A solution to this problem is the use of proteobacteria Azospirillum brasilense as an inoculant. However, experimental results regarding this inoculant vary depending, for instance, on the soil cultivation practices used. The objective of this study was to evaluate the influence of inoculation with Azospirillum brasilense on morphophysiological characters and yield characteristics of three maize genotypes in two off-season cultivated in no-tillage system (NT). Fallow soil (FS) was used as control. The results showed that soil cultivation had a significant effect on morphophysiological and productivity parameters compared to inoculation with Azospirillum brasilense. There were no distinct morphophysiological differences among the treatments. FS (inoculated or not) was more closely related to productivity parameters (grain yield-YI, weight of 100 seeds-100SW, plant height-PH and number of leaves-NL) than NT in both off-seasons. Among the hybrids, Dekalb 255 PRO3 (DKB 255) showed the highest YI and 100SW. Thus, this hybrid was considered well-adapted to off-seasons in western Paraná, Brazil. The inoculation effect was practically null and did not influence the estimated productivity of the different chosen hybrids.
