Had a neighbor plant some Becks this year. I was waiting for it to go downhill with the dry spell we had. It was planted on soil where there is gravel at 20 inches. I checked the moisture a couple of times and it was dry down to 20 inches. That field hung in there better than other fields with better soils, which amazed me. Come to find out he cheated some, the hybrid was kind of drought tolerent and the population was variable rated.
