Nutrient Management and Optimized Fertilization on Wheat and Maize in Henan Province

The project has been focusing on Nutrient Expert based fertilizer recommendation since 2010

IPNI-2006-CHN-HA16

This study was conducted to validate Nutrient Expert(R) (NE)-based fertilizer recommendations for summer maize and winter wheat and compare them with farmer fertilizer practice (FP). Two NE field validation experiments were conducted in Hebi town of Henan Province. The winter wheat and summer maize was the fourth and fifth successive crop, initiated with maize in the summer of 2012. Read more

Interpretive Summary

This study was conducted to validate Nutrient Expert(R) (NE)-based fertilizer recommendations for summer maize and winter wheat and compare them with farmer fertilizer practice (FP). Two NE field validation experiments were conducted in Hebi town of Henan Province. The winter wheat and summer maize was the fourth and fifth successive crop, initiated with maize in the summer of 2012.

This study was conducted to validate Nutrient Expert® (NE)-based fertilizer recommendation for winter wheat and summer maize in farmer fields and compare them with farmer fertilizer practice (FFP). For this project, nine on-farm wheat and three on-farm maize experiments were conducted in Hebi and Zhengzhou, in Henan Province.

Nutrient Expert®-based Fertilizer Recommendations for Winter Wheat and Summer Maize in Henan, 2012. This study was conducted to validate Nutrient Expert® (NE)-based fertilizer recommendations for winter wheat and summer maize in farmer fields and compare them with farmer fertilizer practice (FFP). For this, 20 on-farm wheat and 17 on-farm maize experiments were conducted in Hebi and Zhengzhou, Henan province.

Nutrient Expert-based Fertilizer Recommendation for Winter Wheat and Spring Maize in Henan, 2011. This study was conducted to validate Nutrient Expert (NE)-based fertilizer recommendations for winter wheat and spring maize in farmer fields and compare them with farmer fertilizer practice (FFP). For this, thirty (30) on-farm experiments were conducted for wheat and 12 for maize in Zhumadian, Henan province.

Nutrient Expert-Based Fertilizer Recommendation for Summer Maize in Henan, 2010 Imbalanced nutrient application and excessive use of N have presented a great challenge to North-central China in recent years. These practices have resulted in losses of yield and profits for farmers, and caused detrimental environmental effects.

Nutrient Management and Balanced Fertilization on Wheat and Maize in Henan, 2009 This project’s goals are to determine the optimal (OPT) rates of N, P, and K fertilizers and provide scientific recommendations for fertilizer application in a winter wheat-summer maize rotation located within the black soil region of southern Henan Province.

Nutrient Management and Balanced Fertilization on Wheat and Maize in Henan Wheat field trials testing N, P, and K rates in Yanjin determined 210-105-105 kg N-P2O5-K2O/ha (OPT) to be the best balanced recommendation. This option produced 890 kg/ha (11%) more than the farm practice (FP) treatment of 195-75-75 kg/ha. Profits under the nutrient omission treatments were 150 to US$500/ha less than the OPT. The highest wheat yield at Yicheng County was 8.

Soil Nutrient Management and Balanced Fertilization in Henan, 2007 In 2007, research activities focused on soil nutrient management and balanced fertilization studies on maize, wheat, and peanut. Three winter wheat field trials were established under an “optimum” (OPT) of 225-120-180 kg N-P2O5-K2O/ha, which was compared to a -N, -P, -K and zero fertilizer check (CK). Four summer corn field trial included an OPT using 225-90-180 kg/ha, plus a -N, -P, -K, farmer practice (FP), and CK.

Nutrient Management and Balanced Fertilization on Selected Crops in Henan, 2006 Henan is one of the main production bases for wheat, corn, and vegetables in China. In 2006, five winter wheat field trials compared a complete treatment of 225-120-180 kg N-P2O5-K2O/ha, which was compared to PK, NK, NP combinations and a zero fertilizer check. Four summer corn field trials included an OPT treatment using 225-90-180 kg/ha, plus a PK, NK, and NP combinations.
