General view June 20,2003Our field is starting to look like a real sunflower field. It's been nine days since we last looked at our field. You can really see a difference.  We've been getting good moisture and the warm temperatures have been just right for sunflower plants. 

Leaf stage 10This is a view of a plant that's in the V10 to V11 stage. These plants are putting on about 2 to 3 leaves per week.  The leaves are a nice dark shade of green, which means these plants have an adequate amount of nitrogen.  If they were nitrogen deficient, the leaves would be lighter green to yellow. 


Cultivated rowWhat do you notice here?  The ground looks rougher and there are no weeds!  We had to run a cultivator through the field to get rid of all the cocklebur plants. It would appear that we did a pretty good job, but we can't get them all. 


HoeingWell, this is something you don't see very often. Someone hoeing  weeds. This someone is Dr. Dale Fjell, crops specialist. Because the cultivator can't get too close to the plants, some weeds escape. So, Dale is hoeing out the weeds that are next to the plants.  


Small late emergerThis small plant is not even half the size of the one next to it. It emerged much later than the other plants. Farmers don't like to see this. This little plant will survive and it will develop a late flower head, but it won't be very competitive with its neighbors and it won't produce much seed. 


Grasshoper and holeI've been wondering what critter has been chewing holes in the leaves.  We caught this grasshopper almost in the act. This is typical grasshopper damage.
