New Crops and Agronomic Trials in the BC Peace 1992 -1999
BC Grain Producers Association

This report summarizes the agronomic trials and new crop trials conducted by the Research Committee of the BC Grain Producers Association. When looking at the fertilizer and copper trials it is important to also look at the weather data for that year. Without adequate moisture, the crop may not have been able to take full advantage of the higher rates of fertilizer. Many of the new crops are more sensitive to weather conditions or require longer growing periods. Poor spring weather can cause very late emergence or poor stands further reducing the chance of fully maturing or reliable yield analysis. In 1996 most of our new crop plots drowned because of a very wet spring and hail in 1998 destroyed all our plots in the South Peace. As a result caution should be used when looking at crops with limited local data available. Test plot yields are significantly higher than field scale results due in part to higher than average fertilizer inputs and management.

CV % 
The Coefficient of Variation % indicates the fair comparison between varieties and the uniformity of a test. Agriculture and Agri-Food Canada and Alberta Agriculture have determined a maximum value of 15% for cereals, 18% for peas and 20% for canola. Any data which has a higher value than the maximum CV is usually discarded. 

L.S.D. 
The Least Significant Difference or range test indicates whether entry results are significantly different statistically. Entry means followed by a common letter are not significantly different at alpha =.10. 

Acknowledgments
Funding for these trials was provided by the BC Investment Agriculture Foundation, BC Peace River Grain Industry Development Council, Peace River Agriculture Development Fund and the BC Ministry of Agriculture and Food. Special thanks are extended to all the individuals and research facilities that have supplied the seed and valuable advice, especially the Crop Diversification Centre South in Brooks, Alberta who supply most of our new crop seed.
