Sow in soil at less than 12 °C?
In each country, the experiment will be carried out with 4 different, early or very early varieties. In case of each of them, 3 sowing densities will be tested. We will thus be able to measure the impact of sowing under a tarpaulin with high densities.
If we get favourable results, these varieties will prepare the way for earlier sowing, especially for grain sorghum: good results would make possible to consider to harvest a few days or even a few weeks early. Thanks to these varieties we could harvest before October, a period during which rains can be very problematic. See you in a few months for the results!
