COTTON IN NEED OF HEAT UNITS

The past week was very favorable for field work. Rains varied greatly across the State, providing some crops with needed moisture while leaving others stressed. With temperatures remaining cooler than normal, however, cotton growers are still concerned that the crop will not receive adequate heat units. A good general rain is still needed in some parts of the State.  Continue reading at Crop Progress 7 27 14.

RAINS HINDRENCE FOR SOME, WELCOMED BY OTHERS

With no end in sight for some producers, rains have drowned out some crop acreages and prevented planting of others. The wet weather is, however, helping soybean and corn development but heat units are still needed for the cotton crop because of its sensitivity to adverse environmental conditions.

Proper Nozzle Selection for Pesticide Applications
Author: Shawn Butler, Graduate Research Assistant No Comments

As we get further into the year, bugs begin to enter our fields, disease onset starts to occur, and weeds continue to flourish, our chances of making tank-mixed applications increase.

WEATHER HAMPERS WHEAT HARVEST; COTTON NEEDS HEAT UNITS

Weather continues to take a toll on Tennessee crops. Some fields have been planted multiple times because of standing water and, in some areas, wheat is still standing due to wet fields. Rains have cooled temperatures, which has a negative effect on the cotton crop through a decrease of needed heat units. Continue reading at Crop Progress 7 13 14 .

HEAVY RAIN SHOWERS IN SOME AREAS, GENERAL RAIN NEEDED IN OTHERS

Persistent rains over the past two weeks are now showing advantages through steady development of crops, though the cotton crop would benefit from more heat units. Steady rains kept some producers out of the field for a time, but diminished enough for wheat harvest to be completed in a few areas. Continue reading at Crop Progress 7 6 14 .

CROP HARVEST AND DEVELOPMENT PROGRESS WELL

The warm, dry weather allowed producers to make excellent progress with wheat harvest, which is still reported to show average to above average yields. The warm weather benefitted the cotton crop, which is squaring a rate above last year and the 5-year average. Persistent rains over the past two weeks are now showing advantages through corn starting to tassel ahead of normal. Continue reading at Crop Progress 6 29 14
