Balanced N and C input recommendations for rain‐fed maize production in northern China based on N balances and grain yields

Abstract

The study suggests that N balances close to neutral be given priority to improving N-use efficiency, and more positive C balances also be important for sustaining target yields and soil fertility levels. © 2017 Society of Chemical Industry.

Maize yield, biomass and grain quality traits responses to delayed sowing date and genotypes in rain-fed condition

“…As a key factor influencing farming activities, sowing time is highly associated with cereal grain yield and quality around the world (Bajaj et al, 2008;Wang et al, 2018). Previous studies have demonstrated sowing time is closely related to agro-meteorological factors, such as effective accumulated temperature, precipitation photosynthetic active radiation, even nutrient uptake (Gaile 2012;Verma et al, 2012).…”

“…Costabr et al, (2013) reported sowing date, varieties and seeding rate significantly affected test weight in bread wheat plants, and grain test weight with delayed sowing showed decrease tends under irrigated Mediterranean systems, and the similar result was also found by Ozturk et al, (2010) in Erzurum (Turkey) dryland conditions. And, the changing in grain qualities by delayed sowing date are related to duration of critical periods for growth or crop establishment, especially for grain filling, but also to genetic and the changes of environmental conditions (Jaliya et al, 2008;Wang et al, 2018).…”
