Farming Strategies for the Future

There was a time in agriculture when greater yields always meant greater profitability. Today’s economic environment is characterized by high input costs and depressed commodity prices. Under this scenario when the optimum input/output relationship has been attained, more inputs do not necessarily result in greater returns on investment. Therefore, todays’ agriculture paradigm requires management that addresses production “optimization”. This is the point where a previously known level of inputs maximizes outputs before incurring into greater investments that result into diminishing returns.

Bacterial Leaf Streak Developing at Low Level in Winter Wheat

A few winter wheat fields were found with bacterial leaf streak starting to develop at low levels. Bacterial leaf streak is usually observed starting from flag leaf growth stage. It can be severe on the upper leaves when there is prolonged leaf wetness resulting from frequent rains.
