The RR plot continues to out perform the Munual Cultivated plot. This year with all the rain, and cool weather - the weeds have been a real problem in the Sweet corn (picture from 7-18-04):
To the left of the sweet corn is about 1.5 acres of feild corn thats doing a little better - but not much. I put down 200 lbs/acre 46-0-0 Urea, Its nice and dark green and about thigh high (so are the weeds). I think it will ear out, but with all the weeds - it will be a poor crop (by farmer's standards).
Here is the 7-18-04 picture of the RR corn:
I had missed some spots in the corn with the one Roundup spraying I did - I resprayed a couple rows by hand - but, really I probably didn't need too. One spraying was enough for the corn - This should be a great 2.5-3 acre corn plot.
Its surprising to some, me included - that the soil in the "weedy plot" is MUCH better that the RR corn plot. In fact, I should ahave taken a picture but did not of the fist 30yds of RR corn I sprayed, where I did not allow enough time for the Roundup to get though the tubes. As a result, I sprayed water only for a little ways (30 yds on 4 rows). The corn in this little section was only about 12" tall, yellow and checked by ragweed. Its hard to believe that the sprayed corn in the picture - is the same planting.
An interesting thing I learned ( or re-learned) was that the innoculant for soybeans IS important. Last year whan I planted Soybeans I did inoculate, and some of the soybeans I planted this year are in the same areas. The 30 yd strip of RR Soybeans I planted in-between the RR corn, is in soil that I did not put the inoculant on - and I forgot this spring to get it.
30 yd strip - No inoculant:
The RR soybeans I planted nearby in the same place as last year's inoculanted soybeans - seem to be Doing better producing their own nitrogen:
I'll probably spray the beans another time, but not the corn - its growing so fast now that I don't think it would make a difference.
