No problem at all spraying and then planting immediately or even planting and then spraying. Depending on your situation it may be better to wait and let your thatch/turf or whatever you are playing into completely “brown out”. You may get better stands that way.
Not exactly no till - but I plant japanese millet for ducks in a slough bed as the water dries up in the summer, but slough bed is still muddy. I have both a sprayer and a spreader mounted on my polaris ranger and spray gly and spread seed on the same pass. Works great.
