Cotton Rotation with Peanuts Presented at 2012 Cotton Field Day

At this week’s bi-annual cotton field day, NC State Extension Peanut Specialist Dr. David Jordan was a bit of a duck out of water. But, his presentation on rotation and weed control was very important for cotton producers:

“We know with peanuts we have a lot of rotations. Cotton and corn are very important for us. In these rotation studies for peanuts, we always have cotton in them, and we learn a lot about cotton from those rotations.

The main message in peanuts that I presented today was not necessarily the rotation, but the tillage component that we were looking at. What we have found over many years is when you are on finer textured soils, reduced till we always struggle to maintain our yields. On course textured soil we can maintain yields fairly well.

The other thing we looked at was the value of reduced till versus conventional for our major agronomic crops, corn and cotton. What we tended to find was, as expected, up and down. But as growers are moving to reduced till, as a rule of thumb they are not losing anything.

In these studies we decided to control the weeds and insect pressure. But we did look at nematode population. And we did find some fairly unique things with the tillage and rotation systems, but we have a lot of different nematodes in a field and one may go up and one may go down so we didn’t have any real concrete conclusions.

Some of these studies go back to 1999, and my hope is that we keep these going another 15 years.”
