The YEN Yield Testing Project is funded by the EIP-Agri (through DEFRA) until 2020.

The project supports YEN entrants in testing their ideas for yield enhancement

Ideas being testing in 2018 are:

  1. ​Potash responses on heavy clays

  2. Value of amino acids

  3. Prolonging canopy life during grain filling​






Ideas Labs.

YEN ideas Labs bring together farmers, advisors, and researchers to discuss yield enhancement. 

The next Ideas Lab will be at Newark Showground on Monday 18th June 2018. 

To register for the 2018 YEN Ideas Lab, please visit the event page

To maximise confidence in results of yield testing, we suggest you plan to:

  • Test your idea on several farms
  • Align treatments across in field soil variation
  • Create a tidy yield map, by careful harvest
  • Get spatial analysis of the yield map (by ADAS Agronomics).

Guide to Farmers' Crop Trials

ADAS has published a guide to help farmers conduct successful on-farm trials.  The full guide can be downloaded using the link below.

ADAS believes that by working together with other farmers, suppliers, agronomists and scientists, farmers can use their own trials to bring fast learning, new findings and best practice for themselves and the industry at large. 

We are now seeking to promote and support this approach internationally; we call it ‘Agronōmics’.

GPS and other modern technologies, along with thorough trial protocols, can make farm trialling straight forward and routine.  Decisions and innovations can then become thoroughly validated and tailored to real farming conditions.

This guide outlines processes leading to successful farm-trialling and how to avoid the pitfalls.

The guide covers trials conducted with ADAS Agronōmics support, trials using yield mapping technology without ADAS support, and trials where the yields are assessed by weighbridge.

YEN Ideas Treasury

Since the YEN began in 2012, entrants have had many ideas for enhancing yields. 







Project Funding


This project is funded by the EIP-Agri, which works to foster competitive and sustainable farming and forestry that 'achieves more and better from less' across Europe.

All participants within the projects are members of the Yield Enhancement Network. 

All fields entered into the YEN Yield Testing programme are also entered into the YEN competition.
