| General Info | Grain Sorghum stages averaged between V9 and V13. The two irrigated fields received their first irrigations this week. The next few weeks will be timely irrigations and hope for rain in Lawrence County. | ||

Field received an irrigation and has really turned around in the last few weeks. Grass is starting to show up in parts of the field, but the nutgrass is dying out. Field will be irrigated again next week. |

This field is in excellent condition. The first irrigation went on this past week and another one is ordered for this week if there is no rain. |

General Info |
This week, the two irrigated fields received timely rains while the non-irrigated field still has not received a decent rain. Fields are sprayed and fertilized and will now just receive irrigations until heading when we will start to scout for insects. | ||

Field received 1.1 inches of rain last week and is starting to really look good. The nutgrass has really started going downhill since the Permit application. One thing that still bothers me in this field is that we have some grass escapes, but we will have to live with it at this stage. Field should receive an irrigation this week, if it didn’t rain there over the weekend. Field is in good shape. |

Field needs a rain badly. Moisture is getting short, but the plants still look good. I would like three good rains on this field at different times, and this is one of the times that we need one. An inch of rain here would go a long way to making a good yield. The atrazine worked well in this field. |
| Prairie |

This field received about 0.3 inches of rain this past week and should get its first irrigation this week. With the past week’s winds, the field didn’t get sprayed with atrazine and now is too big to spray. This field is clean though, and we should be okay. |

All three fields have really jumped this week. All fields have received fertilizer and herbicide applications. The Ashley County field received a shot of Atrazine and Permit last week. The nutgrass in this field was about to take over, but after this past week’s visit, the grain sorghum has started outgrowing the nutgrass. This field should have received an irrigation this past weekend.
Prairie County is growing nicely and will receive Atrazine as soon as the wind dies down. This field will receive an irrigation later this week.
Lawrence County's field is non-irrigated and could really use a rain. The field has been sprayed with Atrazine.

The field in Prairie County was planted last week. This means all three fields are in the ground and growing. The oldest field is located in Ashley County. This field went through a bout with thrips the week before last. On May 2, the field got two inches of rain and possibly some hail. The Ashley County field also has a bad nutsedge problem. When I looked at it last week, it was still growing, but didn’t look good at all. Hopefully, with a good week of warm, dry weather, it will get back on track. If it begins to look healthier, we will talk about spraying it soon. The field in Lawrence County is coming along just fine. It emerged last week and appeared to be in good shape. I wouldn’t mind seeing a few more rains on this field, since it is non-irrigated.
May 5, 2008
The field in Lawrence County was just about to break through the soil surface last week. That field should have emerged by the weekend and stand counts can be taken this week. About one inch of rain fell at that field last week. The field in Ashley County has emerged and stand counts were taken. The field averaged around 105,000 plants per acre. The field has nutsedge that will have to be controlled. The plants had a great number of thrips that have me concerned. Thrips are usually not a problem in grain sorghum, but we will watch them closely over the next few days. That field received 1.6 inches of rain over the past week. The field in Prairie County is scheduled to be planted today in Pioneer 84G62. This week’s forecast calls for more rain and storms. Heavy rains at Prairie County could be costly if they occur immediately after planting.
April 28, 2008
Two of the three GSRVP fields were planted last week. Ashley County was planted on April 21, with Pioneer 84G62 at 8.7 pounds per acre. The field is on 7.5 inch rows and will be furrow irrigated. The following day, the field was sprayed with 1.5 pints of Charger Basic (metolachlor) and then received a 0.6 inches of rain. The Lawrence County field was planted on April 23 with FFR 322 at 6.5 pounds per acre. The field consists of 30 inch beds and follows soybeans. The field was sprayed with 1 pint of Parallel (metolachlor). These fields should be emerging this week. The Prairie County field should be planted this week.
April 21, 2008
The sunny warm days have allowed for field work to begin on the Grain Sorghum Verification Fields. One of the fields should be planted early this week. If everything goes right, the other two should be planted by the end of this week or at the beginning of next week. Hopefully, I will have more to report on next week.

This year, we will have three grain sorghum fields enrolled in the Grain Sorghum Research Verification Program (GSRVP). Table 1 gives a summary of the counties, agents, cooperators and hybrids for this year. Rain continues to fall and field work has come to a stop. We still have plenty of time to plant grain sorghum and would like to see some warmer soil temperatures before we think about planting. Two of the fields (Ashley and Prairie) will be irrigated this year, and the Lawrence County field will not be irrigated.
