“…Numerous studies have reported that changing the sowing date is an effective method to achieve high yields (Bassu, Asseng, Motzo, & Giunta, ; Bonelli, Monzon, Cerrudo, Rizzalli, & Andrade, ; Tsimba, Edmeades, Millner, & Kemp, ,b; Zhou et al., ). Changing the sowing date of maize changes the growing environment from sowing to harvest, which in turn affects maize growth and yield (Hegyi et al., ; Liu, Hou et al., ; Liu, Xie et al., ; Ruiz Corral et al., ; Tsimba, Edmeades, Millner, & Kemp, ,b). In our study, according to a delay in sowing date, the yield varied from year to year (Figure ).…”

The North China Plain (NCP) is one of the major areas of cereal production, and in recent years its maize (Zea mays L.) production has been influenced by both heat and chilling stresses. Adjusting the sowing date is an effective measure for mitigating these stresses. However, the underlying mechanisms remain poorly understood. We performed a 5‐year field experiment to determine how the sowing date mitigated heat and chilling stresses at Wuqiao Experimental Station in the NCP with three treatments: early sowing (ES), middle sowing (MS), and late sowing (LS). In all 5 years, higher grain yields were observed in the MS (averaged 11.7 Mg/ha) and LS (averaged 11.4Mg/ha) treatments compared with the ES (averaged 10.9Mg/ha) treatment. The lower yield in ES treatment mainly resulted from high temperature 5 days pre‐silking and 5 days post‐silking (>31.8°C). In 2015 and 2016, the lower grain yield in LS (11.4Mg/ha in 2015 and 11.2Mg/ha in 2016) treatment compared with MS (12.1Mg/ha in 2015 and 11.9Mg/ha in 2016) was mainly because the minimum temperature was <13.0°C 5 days before maturity or <13.6°C 10 days before maturity. Long‐term weather data further verified middle sowing would be appropriate in a changing climate. Therefore, we can conclude that sowing date manipulation constitutes a useful method for mitigating heat and chilling stresses for maize production.

“…Previous studies investigated the adaptability and stability of different maize varieties (Ruiz Corral et al, 2008;Hegyi et al, 2005;Scapim et al, 2000); however, few studies focused on the spatial variation in maize yield and aboveground biomass weight, particularly for a widely cultivated maize hybrid over a large region. Ecological factors, especially climatic factors, had widespread effects on maize growth and yield.…”

“…Ruiz Corral et al (2008) studied the climatic adaptation of 42 Mexican maize cultivars and found that maize had evolved adaptability beyond its environment range. Hegyi et al (2005) studied maize's adaptability to various climatic conditions and found that maize yield and yield components were influenced the most by the year of study followed by the maize cultivar and planting location.

Environmental conditions have important effects on maize (Zea mays L.) growth. To examine spatial variation in maize yield and aboveground biomass and to understand differences in the response of maize yield and aboveground biomass to climatic factors under various ecological conditions, we conducted experiments from 2007 to 2010 at 34 locations in seven provinces in the spring maize region of northern China between 35°11′ N lat and 48°08′ N lat. We used a most widely cultivated maize hybrid ZD958. The maize yield and aboveground biomass (presilking and postsilking) were found to be strongly influenced by locations. A nonlinear relationship existed between the maize yields and latitude. Maize yield was the greatest (12.19 Mg ha–1) at 39°08′ N lat, and the corresponding presilking and postsilking aboveground biomass at this location were 143.41 and 215.35 g per plant, respectively. Variations in the harvest index (HI) and 1000‐kernel weight were the main reasons for yield latitudinal trends. Among the climatic factors, air temperature had the best relationships with variations in maize yield, HI, and 1000‐kernel weight. With latitudes increasing northward, presilking aboveground biomass affected by growth duration length and accumulated solar radiation increased significantly. The aboveground biomass of postsilking stage that was affected by the maximum temperature, daily mean temperature, and growing degree days decreased significantly with latitudes increasing northward. However, there were no significant changes of total aboveground biomass with latitudes increasing northward.

“…Berényi (1945) found that rainfall fluctuations in July had a greater influence on the grain yield than temperature variability. Gyenesné et al (2002) recorded a close positive correlation between ear yield and the rainfall quantity in July (Hegyi et al, 2005). Long-term water deficiency during flowering increased the frequency of aborted kernels in the ears (Zinselmeier et al, 1995).…”

A total of 96 hybrids from four maturity groups (FAO 200, 300, 400, 500) were tested in two years (2006, 2007) at two locations in Hungary (Martonvásár, Szarvas). Considerable differences were found between the years for the grain yield per hectare and for the grain quality parameters. In 2006 record yields were achieved at both locations, averaging 11.61 t/ha in Martonvásár and 12.20 t/ha in Szarvas, due primarily to well-timed irrigation in Martonvásár and to good rainfall supplies in Szarvas. In 2007 both locations suffered from drought, with less rainfall than average during the critical months of the vegetation period, which was partially compensated for by irrigation in Martonvásár, giving a yield average of 5.96 t/ha, while the hybrids grown in Szarvas had a yield average of 5.06 t/ha. The grain quality parameters exhibited a close correlation with the grain yield in the individual FAO maturity groups. Hybrids of the flint type, which have a short vegetation period, had high protein and oil contents, but the yield averages were low due to the slower rate of starch incorporation. Hybrids of the dent type have a longer vegetation period and more intense carbohydrate accumulation, but low protein and oil contents. In wet years and locations there was a higher rate of starch accumulation, while dry years are favourable for protein and oil accumulation. The Bravais correlation coefficient was calculated between the yield and the grain quality parameters (averaged over years, locations and varieties). A positive, moderately strong correlation (0.68) was found between the yield and the starch content, a negative, moderately strong correlation (-0.52) between the yield and the protein content, and a loose negative correlation (-0.19) between the yield and the oil content.
