Can increased plant stand impact pith expression in wheat to protect from wheat stem sawfly on dryland?
Some research has shown that stand density can impact solid stem expression and pith density in wheat stems. In hollow stem cultivars higher yields and possibly thicker pith levels in stems can be achieved even in Southern Alberta dryland. You may be able to experiment up to 40 plants per square foot targets when normally we are at 25-30 plants per square foot. Although this does seem high to me, possibly trying a few passes at that rate may show less sawfly problems. Details here:
