Solar driers help preserving vegetables
Recognize the problem
Vegetables are often difficult to grow as they are easily attacked by various
insect pests and diseases. But even after a good harvest, losses in vegetables
occur because they quickly perish. They either get rotten or lose their
nutritional value. Then they are useless for consumption.
Background

How to identify Spodoptera armyworms on maize
Recognize the problem
Spodoptera is a genus of moths which caterpillars cause damage to a variety of crops,
including maize. They consume the leaves, creating holes and ragged leaf edges.
Feeding through the maize whorl can cause a line of identical “shot” holes, when the
leaf unfurls. Caterpillars also burrow into cobs and feed on...

Prevention of phosphorus deficiency in maize
Recognize the problem
Phosphorus is one of the most critical nutrients for maize production. Its
deficiency results in reduced yields and is common in soils in many parts of
Malawi. Symptoms of phosphorus deficiency are that young plants look
dwarfed and thin with dark green leaves. Leaf margins, veins and stems show
purple tints...

Prevention of potassium deficiency in maize
Recognize the problem
Potassium is a vital nutrient for maize production second to nitrogen in terms
of quantity of a maize plant’s needs. Its deficiency is first seen on young lower
leaves which are green and turn to yellow and brown colour. This may
progress to upper leaves. Curling leaves with inter-veinal scorching and
necrosis....

Prevention of calcium deficiency in groudnuts
Recognize the problem
Calcium is one of the most important but less mobile nutrients in plants. In
groundnuts, it is responsible for pod formation. Its deficiency is therefore
reflected in poor pod formation resulting in a fewer number of and small ill-
developed pods per plant. For vegetative growth, it is manifested as localized...

Recognize the problem
Potassium deficiency in potato results in poor quality tubers and reduced
yields. The problem of potassium deficiency is common in soil in many parts of
