The Essential Role Of Nutrition For Potatoes

Good Nutrition...

Increases quality and yield

Crop Cycle

Vegetative Growth

# Emergence
# Root and leaf growth
# Stolon development

Reproductive Growth

# Tuber initiation
# Tuber bulking
# Maturation

Good Nutrition Is Vital During The Vegetative Stage To Produce A Quality Crop

Magnesium

# Central component of chlorophyll molecule (no chlorophyll - no green leaves)
# Part of water uptake mechanism (no water - no crop)
# Factor in P and N metabolism (no P or N - no yield)

Manganese

# Enzyme activator in photosynthesis (no photosynthesis - no growth)
# Part of leaf detoxification system (unhealthy leaves - no growth)

Tuber Initiation

When tuberous swellings reach twice the diameter of the rest of the stolons

Plant produces more sugar and energy than is needed for growth - this accumulates behind stolon tips

With extra energy rapid cell division occurs and the tuber is formed

Even-ness and frequency of tubers is connected to nutrition

Phosphorus is particularly important

Phosphorus

Involved in sugar and energy manufacture in the leaves

Supplies the plant with power to set tubers

Increases tuber numbers

Tuber Bulking

Cell division ceases and cell expansion begins

cells grow 7 to 18 times in size

starch and carbohydrates deposited in tuber cells

dry matter and specific gravity increase

Phosphorus and magnesium are both important at this stage

Phosphorus

Phosphorus moves from leaves to tubers in large quantities

Inadequate leaf P levels may result in premature senescence

Premature senescence seriously reduces yield

Phosphorus increases tuber size

Magnesium

Extra Magnesium Means...

# Greener Leaves For Longer Periods Of Time
# Optimum Sugar Production
# More Energy
# Higher Yield
