Seeding into stubble -  the effect of stubble height on lentil growth locations
Aims

To investigate the effect of full stubble retention compared with other stubble management methods and seeding technologies

Key messages

There were no significant differences in lentil grain yield among stubble treatments. As seen in 2013, stripper and conventional stubble treatments resulted in taller and more erect lentil plants
