Ethylene enhanced waterlogging tolerance by changing root architecture and inducing aerenchyma formation in maize seedlings.

Waterlogging negatively affects maize growth and yield. In this study, we found that ethylene played a vital role in plant adaptation to waterlogging. ET promotes better growth in seedlings under waterlogging conditions by altering root architecture and increasing lateral root formation by 42.

Rice Paddies Reduce Subsequent Yields of Wheat Due to Physical and Chemical Soil Constraints.

Yields of wheat crops that succeed rice paddy crops are generally low. To date, it has been unclear whether such low yields were due to rice paddies altering soil physical or mineral characteristics, or both. To investigate this quandary, we conducted field experiments in the Jianghan Plain to analyze differences in the spatial distribution of wheat roots between rice-wheat rotation (RW) and dryland-wheat rotations (DW) using a range of nitrogen treatments.

An ABA Functional Analogue B2 Enhanced Salt Tolerance by Inducing the Root Elongation and Reducing Peroxidation Damage in Maize Seedlings.

Salt stress negatively affects maize growth and yield. Application of plant growth regulator is an effective way to improve crop salt tolerance, therefore reducing yield loss by salt stress. Here, we used a novel plant growth regulator B2, which is a functional analogue of ABA.

Comparison of early season crop types for wheat production and nitrogen use efficiency in the Jianghan Plain in China.

The rice-wheat (RW) cropping system is one of the most prevalent double-cropping systems used to farm the Jianghan Plain in China. However, it can lead to low wheat yields and reduced nitrogen use efficiency compared with dryland wheat (DW). We evaluated wheat yield and nitrogen use efficiency for two rotations (summer rice-winter wheat and summer soybean-winter wheat) from 2017 to 2019 and applied the results to improve nitrogen management for planting wheat after rice in the Jianghan Plain.

[Differences of wheat yield and economic benefits between soybean-wheat and rice-wheat cropping under different nitrogen fertilization patterns in Jianghan Plain, China].

We analyzed winter wheat yield and growth pattern of soybean-wheat and rice-wheat rotation systems in response to different nitrogen fertilization patterns with the aim to provide theoretical basis for narrowing the wheat yield gap between the two rotations in Jianghan Plain. Field experiments were conducted with three treatments, control without nitrogen, traditional nitrogen management (70% nitrogen as basal and 30% nitrogen as topdressing at overwintering), and improved nitrogen management (one third of N was applied at sowing, wintering and jointing, respectively). The growth pattern, grain yield, yield components, fertilizer use-efficiency and economic benefit under the different nitrogen fertilization patterns were examined.
