Interpretive Summaries:
Seed-placed Boron for Canola and Cereals, 1997
Many producers are interested in boron (B) and its potential to increase cereal and oilseed yields in western Canada. And, because of the interest in direct seeding and low application rates required, most farmers would prefer to place B in the seed row at planting. However, past experiences placing B in close contact with the seed has many producers worried about possible injury to seedlings. This study evaluated seed-placed and broadcast B. When seed-placed B was spread over 25% of the seedbed, higher application rates (i.e. 2-3 lb/A) had a minimal effect on barley and canola germination, unless the seedbed was dry. However, when only 5% of the seedbed was utilized, seed-placed B reduced emergence of barley and canola. In fact, any seed-placed B severely reduced canola emergence. Broadcast application was shown to be the most effective way to apply B to canola. AB-17F
