| I did some research on some threads on population rates on dryland corn and seen that a rate of 1000 seeds per ac for 10 bu expected. With the price of corn seed we are trying to keep our dollars down on the marginal ground and wondered if this is a viable way to do this. this ground is in northern central oklahoma ph 5-6 om 1 or less cec 5-8 mostly sand rainfall around 22-25 inches. On a lot of these sand hills if it is a wet year it will do 70-90 but if there is a dry spell they burn up at 18500. If this holds true on rate we could save some seed on these areas plus give them some more potential. We had some rodent damage in some of these sandy places and where the pop was lower some more than others there was noticably larger ears from the combine seat the only reason why I say this is because there were no ears on the other stalks or just barely formed where the higher population. Any insight will help us on decision making and we are willing to try just about anything. We intend on having variable rate seeding on the planter to build rx for these areas on keep the higher rate on the better ground. Thanks for any info,
Luke. | |
