Crop Update 6-20-13

The sun has been welcomed and crops are rapidly growing in South Central Nebraska!  Corn right now is between V6-V8 (6-8 leaf) for the most part.  Quite a few farmers were side-dressing and Corn that's been hilled in south-central Nebraska.hilling corn the past two weeks.  It never fails that corn looks a little stressed after this as moisture is released from the soil and roots aren’t quite down to deeper moisture.

Installing watermark sensors for irrigation scheduling, we’re finding good moisture to 3 feet in all fields in the area.  The driest fields are those which were converted from pasture last year and we want to be watching the third foot especially in those fields.  Pivots are running in some fields because corn looks stressed, but there’s plenty of moisture in the soil based on the watermark sensor readings I’m receiving for the entire area.  So we would recommend to allow your crops to continue to root down to uptake deeper moisture and nitrogen.

The last few weeks we observed many patterns from fertilizer applications in fields but as corn and root systems are developing, they are growing out of it.  We’ve also observed some rapid growth syndrome in plants.  This can result from the quick transition we had from cooler temperatures to warmer temperatures, which leads to rapid leaf growth faster than they can emerge from the whorl.  Plants may have some twisted whorls and/or lighter discoloration of theseOn-farm Research Cooperators, Dennis and Rod Valentine, get ready to spray their corn plots with a sugar/water solution.  Their study is to determine the effect of applying sugar to corn on yield and economics.  leaves, but they will green up upon unfurling and receiving sunlight.  This shouldn’t affect yield.

Damping off has been a problem in areas where we had water ponded or saturated conditions for periods of time.  We’ve also observed some uneven emergence in various fields from potentially a combination of factors including some cold shock to germinating seedlings.

We began applying sugar to our on-farm research sugar vs. check studies in corn.  We will continue to monitor disease and insect pressure in these plots and determine percent stalk rot and yield at the end of the season.

Leaf and stripe rust can be observed in wheat fields in the area and wheat is beginning to turn.  We had some problems with wheat streak mosaic virus in the area again affecting producers’ neighboring fields when volunteer wheat wasn’t killed last fall.  Alfalfa is beginning to regrow after first cutting and we’re encouraging producers to look for alfalfa weevils.  All our crops could really use a nice slow rain right now!
