Area of Focus


Research Interests

  • Crop physiology
  • Crop response to abiotic stresses
  • Yield potential
  • Yield-gap analysis
  • Resource-use efficiency
  • Crop simulation models

Major Project Activities

I am currently involved in three major projects:

  • Global Yield Gap and Water Productivity Atlas: I have estimated yield gap and water productivity for maize, wheat, rice and legume crops in US, Africa, Indonesia, Mexico, and others countries. Link: www.yieldgap.org
  • Benchmarking yield and input-use efficiency of soybean systems: I have worked with producer self-assessment data in a project aimed at Benchmark soybean production systems in the North-Central USA to identify KEY management factors that can be used by individual producers to increase yield on their farms.

  • Yield Forecasting Center: In this project, we provide in-season maize yield forecasts to aid growers and the Ag industry in making management, logistics, and marketing decisions through the season. The Yield Forecasting Center consists of a core team at UNL in collaboration with agronomists and extension educators from universities throughout the Corn Belt.

Extension Interests

I have participated in extension activities like University of Nebraska–Lincoln Crop Extension Clinics and extension publications like CropWatch articles. I also perform bi-weekly, in-season, real-time forecasting of irrigated and rainfed end-of-season corn yield potential for several locations across the US Corn Belt , which are periodically published as CropWatch articles during the crop season.
