Grain Sorghum Production Calendar
Grain sorghum producers in Oklahoma must schedule management practices to maintain their profit margin. Timely application of production inputs is important in limiting costs and preventing a crop failure. Planning ahead and predicting when certain input decisions will be arising is one way to avoid split second decisions and possible profit reductions.
A yearly planning guide allows producers to visualize or document the steps they will consider when producing a crop in a particular field. This calendar is designed as a guide or reminder for producers to check on equipment, pesticide needs, fertilizer, seed purchases, planting, irrigation and harvest. This calendar is intended to help producers in constructing their own personal calendar which will reflect each producers needs. A personal calendar for grain sorghum will allow producers to check progress on particular inputs. A calendar can also serve as a guide for hired help or scouts when they have the responsibility to keep track of a particular field or operation.
Use of the Calendar
This calendar outlines the crop growth stage and crop management decisions that should be made at a particular time in the growing season. Producers can use this calendar for irrigated or dryland grain sorghum planted in May through June. Double cropped or late planted grain sorghum would begin the actual growing season in July, with pollination generally occurring after the hottest part of August. The time frame for each management decision will vary with location in the state. Grain sorghum will grow through each stage listed to maturity. Identifying the growth stage may be in many cases more useful than the actual date in making management decisions.
