Southern Missouri | We’re a typically 4.1 to 5.1 area ,a few years ago started being a lot of 3.5 maturity planted here, we’re kind of hard to model after because of everything in this area is precision leveled and furrow irrigated, the biggest difference we see in the two maturity ranges is you can not let the fast maturing varieties hurt any at all especially during their vegetative period which only lasts an incredibly short period here as they start blooming very fast, we have our irrigation in place by the time they are half knee high and don’t hesitate to run the water down the furrows. We typically start harvest of the 3.5 varieties the first of September, we plant about half our soybeans in 3.5 and then plant the other half in 4.8 varieties, we pick our corn in between the two maturity ranges . The 3.5s are in full bloom swing around the longest day of the year which we like, they also don’t seem nearly as susceptible to nearly all the soybean production problems as far as nematodes all the way to the fungal diseases. We are very guilty here of turning the water on to everything we grow as soon as it looks like it might like a drink, our water table is very plentiful and very cheaply pumped and once we lay out the flexible tubing there’s virtually no maintenance outside the turbine pump and energy source for it , electrical or diesel , so we don’t hesitate to turn the water on and some times we probably hurt the late maturing beans by growing them too tall, you don’t have that issue with the short season varietal, they won’t get too tall. We plant twin rows on top of 38 inch wide beds effectively giving us 19 inch row spacing population, hope this helps , just how it is here . | |
