No matter what growing conditions a crop is under, there will always be mitigating factors present that hinder its growing success. Below are some examples of the common stressors found in crops all over the world. Also find solutions in how best to deal with these situations.

Alternate Year Bearing

Perennial trees, vines, and bushes will have a large crop of fruit during one year and the next year the crop of fruit is smaller. This has been normally followed by a larger crop of fruit the following year. The sequence of large yields and then smaller yields are very common to many of our perennial fruiting plants.

Controlling Growth and Appearance of Fairway Grass on Golf Courses

During the summer, when there may not be the appropriate amount of rain or the normal temperatures are too high, it is very difficult to control the growth and the color of fairway grass. This is a common problem on all golf courses.

Drought

When the soil dries out, the plant begins to wilt for the lack of water in plant tissue. As the plant dries out, both the roots and the upper part of the plants become dehydrated. This dehydrations process kills plant cells as they are no longer able to have enough water to carry out their normal photosynthesis and respiration activities.

Early Dying of Soybeans

Years of research has proven that soybeans that contain a lot of pods will die earlier. This will limit the seed size. Soybean plants that have fewer pods will live longer and the bean size will be longer. Therefore, it is difficult to consistently raise high yields of soybeans! When a soybean plant is heavy podded, and has a greater number of seeds, the additional seeds promote a hormone which causes the nodules to die and causes the leaves to quickly senescence. Therefore, a heavily podded soybean plant will normally have a shorter life and dies more quickly than a soybean plant with fewer pods.
The soybean plant with fewer pods does not have as many seeds, which in turn produce less hormone to kill soybean nodules and cause tissue dying in the leaves.

Lack of Flowers

Many of our tree crops lack bud formation for flowers. This is particularly true on older trees that have vigorous shoot growth. Many times these trees have been planted on vigorous root stock. Each year, as the trees tend to vegetate more, the lack of flower buds and flowers become less and less.

Problems with Micronutrients on Glyphosate Resistant Crops

Many corn varieties and soybean varieties which are glyphostate resistant will often show micronutrient problems following the applications of glyphosate. These problems may also show when glyphosate is used as a knock down herbicide immediately before planting.

Sucking Insects

Under certain growth conditions, sucking insects will attack a plant. Normally, they attack the new developing tissue on the top of the plant. As long as climatic conditions remain favorable, these sucking insects will remain on a plant and do significant damage. When the climate changes and the plant once again grows normally, the sucking insects will disappear.

Summer Fruit Drop

During the summer period many fruit trees experience summer fruit drop. This occurs on almost all trees. It occurs approximately 80 days after flowering.
Growers will tend to fertilize the trees before the summer fruit drop period in order to get more new shoot growth. They realize that additional shoot growth will tend to reduce summer fruit drop problems. The effectiveness of this practice will depend upon the climate conditions and the amount of new shoot growth that is promoted by the fertilization.
Even though the above practices are implemented, (even where irrigation is available) the summer fruit drop is still present. The amount of fruit drop will depend upon the climate conditions as well as the variety of the tree crops that are being treated.

The Lack of Grain Sizing on Wheat or Barley

Grain sizing on either wheat or barley is determined by how early the plant dies. If the plant lives longer the grain sizing and the number of grains per seed head will become greater. The maximum yield will be obtained when the grain is ready for harvest and the stem is still green.

Weak Flower Pollination

Poor pollination is a common problem on many perennial trees, vines, and bushes. Pollination and fruit set can widely vary from year to year. Poor pollination can also be the consequence as the plants grow older.
