Yield-Maturity Relationships of Summer Maize from 2003 to 2017 in the Huanghuaihai Plain of China

Abstract: Information on yield-maturity relationships is important for maize breeding and cultivation, but it is seldom available in geographic zones where there are limited heat resources for summer maize. Two novel systematic crop yield models were put forward in terms of production efficiency. These models as well as three other conventional models were used to analyze the crop yield and maturity dataset of 23,691 records that were collected from the annual reports for the national summer maize zonal trials conducted… Show more

“…Relative maturity affects plant population relationship with grain yield. Yang et al [30] indicated that early season hybrid maize showed higher increased yield with increasing plant population than the full season hybrids [31]. The results of the present study are in contrast to Wang et al [32] who found that there is high probability for the full season hybrids generally to produce higher yields than early season hybrids, while full season hybrids showed 33% of chance to produce higher yield less than early ones.…”

“…According to earlier work, it has been predicted that a 2.0 °C rise in average temperature can lead to a more than 20 to 40% reduction in cereal grain production, particularly in Asia and Africa. Furthermore, temperature rise can have either negative or positive impacts on crop productivity depending upon regions 36 48 . Shift in the seasonality is the one of the big example of rise in temperature 49 .…”

“…Nevertheless, the challenge remains, that is, the challenge of obtaining earlier maturity cultivars with grain yield equivalent to the yield of normal cycle cultivars. Some studies on common bean and other species indicate, as expected, that the correlation between grain yield and early maturity is negative (Iqbal et al, 2007;Yang et al, 2019;Guilherme et al, 2021). For that reason, the question arises as to what options there may be to mitigate this negative association.…”
