Potato

This section describes the potato growth cycle and its stages through a practical and dynamic approach. In addition, you will also find a guide detailing the main nutrient deficiencies that can affect your crop and how to identify each of them.

Nutrient Deficiency

Zinc
Plants with a zinc deficiency have limited growth with short internodes and small new leaves. These leaves may be lance -shaped and the borders may curl upward. The leaves at the growing point are generally seen in a vertical position. New leaves may also be chlorotic.
MICRONUTRIENTS
Manganese
Young leaves show internerval chlorosis. They may also tend to have a bronze colour and as the de ciency increases in severity, dark spots may appear along the leaf veins.
MICRONUTRIENTS
Boron
Plants with boron deficiency normally have retarded growth. The new leaves are small and badly formed with short internodes appearing on the leaf. De cient new leaves are generally thicker and more fragile. They may curl upwards and show marginal necrosis. A dark area may occur in the form of striping along petiole base. In certain cases, the main shoots may die causing excessive lateral shoot formation
MICRONUTRIENTS
Iron
The de ciency starts as a symptom of internal necrosis on new leaves.The leaf veins still remain green. The chlorosis may increase and cover up the entire leaf. This problem will occur mainly on high pH soils.
MICRONUTRIENTS
Copper
Copper deficiency is usually not prominent on potatoes unless they are grown in high organic soil. In deficient plants, there is an initial occurrence of a darkening of the veins in the younger leaves. In deficient plants, there is an initial occurrence leaves may become less turgid and even dry as the
MICRONUTRIENTS
Molybdenium
Molybdenium is necessary for nitrogen use efficiency. This deficiency resembles that of nitrogen which can lead to leaf death. Molybdenum deficiencies usually occur in acid soils which reduces availability.
MICRONUTRIENTS
Nitrogen
Symptoms begin on the older leaves, which acquire a pale green or yellowish colour. As the deficiency increases , these leaves may turn completely yellow and die. The plants normally igrow slower and are greatly reduced in size.
MACRONUTRIENTS
Phosphorus
The borders of older leaves are yellowish and necrotic. The deficiency may lead to the appearance of wrinkles or badly formed leaves, which have a very dark green colour. These dark green leaves will loose their glossiness and be curved upwards. A purple colour may appear on older leaves. Plants will have reduced growth with a loss in yield
MACRONUTRIENTS
Potassium
The older leaves become yellow and later suffer necrosis along the edges and the apex. Deficient leaves become arched downwards as if they become wilted. The internodes are short and tuber production can be greatly reduced.
MACRONUTRIENTS
Magnesium
Smaller development of the newer leaves where margins appear to be curled upwards. Stems are generally quite thin. Yellowing may occur and late necrosis may appear on leaf margins. Necrosis may appear at the tuber apex, which will then have sprouts. Death of roots may also occur.
MACRONUTRIENTS
Calcium
The symptoms of deficiency initiates with internal chlorosis of the older leaves. The chlorosis may increase to where necrotic spots appear on the leaves of which margins remain green.
MACRONUTRIENTS
Sulfur
Chlorosis begins on the borders of new leaves until it progresses and covers the whole leaf. These leaves may also show slight curling of the leaf blades.

We were having a very rough year on account of the draught when I used Stoller products, and our yield was still 15% higher than average.”

After I used Stoller, I noticed the trees, branches and sprouts started looking better and more uniform.”
