Hi all. I have a small wheat field which I am about to harvest and I am thinking of putting a leguminous ground cover and covering the field with wheat straw as mulch. WhAt should I do about the stubble? Will it cause problems? Should I set it on fire as is conventional here? Should I till it in? Will the stubble cause any problems? We're at the beginning of the dry season here and it will be very hot and dry till the monsoon two months later.
I would recommend leaving the stubble standing, assuming you will either broadcast the legumes or use a seed drill for planting. The stubble will reduce wind velocity and provide patchy shading, which will create a favorable microclimate for germination and growth of the young plants.
If the stubble is very dense, you could harrow the field lightly before seeding to knock down more of the residue and get the right density. If you post a photo of the field, I can give a better recommendation of whether a harrowing would be beneficial.
