Global Maize Project in China: Liufangzi, Gongzhuling, Jilin Province

Project was initiated in 2009 to test how the performance of ecological intensification (EI) compares to that of current farmer practice (FP)

IPNI-2009-CHN-GM20

The long-term field trial of the Global Maize Project was initiated at Liufangzi, Gongzhuling city, Jilin Province in 2009. The successive mono-cropped spring maize, the dominant cropping system in northeast China, was the test crop for this experiment during the last eight years. Maize grain yield and nitrogen (N) use efficiency were investigated to compare the performance of two main treatments, the ecological intensification (EI) and the farmers’ practices (FP). Read more

Interpretive Summary

The long-term field trial of the Global Maize Project was initiated at Liufangzi, Gongzhuling city, Jilin Province in 2009. The successive mono-cropped spring maize, the dominant cropping system in northeast China, was the test crop for this experiment during the last eight years. Maize grain yield and nitrogen (N) use efficiency were investigated to compare the performance of two main treatments, the ecological intensification (EI) and the farmers’ practices (FP).

This long-term Global Maize field trial was established in 2009 at Liufangzi, Gongzhuling city, Jilin Province. This year was the 7th season of monocropped spring maize. Multiple effects of ecological intensification (EI) were investigated to compare yield and N use efficiency against farmers’ practices (FP). In 2015, spring maize was planted on May 1 and harvested on September 30.

This long-term field experiment was initiated in 2009 in Liufangzi, Gongzhuling City, Jilin Province, where mono-cropping of spring maize is common. The aim of the experiment was to compare the performance of ecological intensification (EI) practices with common farmers’ practice (FP) for yield and N use efficiency.

Global Maize Project in China: Liufangzi, Gongzhuling, Jilin Province, 2012 This long-term field experiment was initiated in 2009 in Liufangzi, Gongzhuling City, Jilin province, where mono-cropping of spring maize is common. The aim of the experiment was to compare the performance of ecological intensification (EI) practices with common farmers’ practice (FP) for yield and N use efficiencies.

Global Maize Project in China: Liufangzi, Gongzhuling, Jilin Province, 2011 This long-term field experiment was initiated in 2009 in Liufangzi, Gongzhuling City, Jilin Province, where mono-cropping of spring maize is common. The aim of the experiment is to compare the performance of ecological intensification (EI) practices with common farmers’ practice (FP) for yield and N use efficiencies.

Global Maize Project in China: Liufangzi, Gongzhuling, Jilin Province, 2010 This long-term field experiment was initiated in 2009 in Liufangzi, Gongzhuling City, Jilin Province, to investigate the performance of ecological intensification (EI) practices to improve yield over time at a faster rate than common farmer practice (FP), while minimizing adverse environmental impacts.

Global Maize Project in China: Liufangzi, Gongzhuling, Jilin Province, 2009 A long-term field experiment was initiated at Liufangzi, Gongzhuling City, in Jilin to investigate the ability of ecological intensification (EI) practices to improve yields over time, compared to farmer practices (FP), while minimizing adverse environmental impacts. In this first year, a split-plot design with four replicates was used.
