[QUOTE="yellow belly, post: 8175848, member: 305"] Black grass will germinate at any time if there is seed and moisture It modus operandi is produce millions of seeds 70 % may often be sterile but 30% still leaves millions A lot germinate in the autumn Leaving plenty for the spring But some will wait till later in April may and June if it rains and there is light on the soil There will still be plenty to have a go on the autumn following early drilling every season only came in in the late 1970s when ipu came along 3 winter cereals followed by osr drilled all in September was the most profitable rotation dry cooler March aprils delay the bg germination in the spring leaving more seeds for may germination the only option is rotation of crops drilling date and chemical if 3% are late germinating and they produce 1 plant per 10 m squared 10 heads with 300 seeds 300 seeds per m the biggest problem is what works one year doesn’t work another year Or what works in one field doesn’t work in the next field 30 to 40 years ago Chemicals worked every year if applied well [/QUOTE]
