Roots grow poorly in dry soil and cannot absorb nutrients for the plant. Too much water also reduces growth and may kill seedlings. Factors affecting seedling growth — temperature • Seedlings grow fast in warm weather. But high temperatures, above 40oC, reduce growth and may kill seedlings. 27 Factors affecting seedling growth — light intensity • 28 Bright sunlight helps seedlings grow vigorously. Lack of light makes seedlings pale and weak-stemmed. Factors affecting seedling growth — nutrients • To grow fast, seedlings need readily available nutrients.

35 Growth stages of soybean — vegetative phase • • 36 The stem grows rapidly, with a new leaf unrolling at each node. Roots begin actively fixing nitrogen by the time the second or third node has developed. Growth stages — late vegetative phase • Six nodes on the main stem have fully developed leaves. • The buds in the axils may develop into branches or into flower clusters. 37 Branching • • 38 Branching starts when the plant is about 20 cm tall. The number of branches depends on the soybean variety and plant density.

From now on dry weight increases rapidly. Nitrogen fixing is also very rapid at this stage. Flowering pattern — determinate varieties • The flowering pattern of the soybean plant depends on the • variety. Determinate varieties begin flowering when most of the nodes on the main stem have developed. Flowering starts at the upper nodes and progresses downwards and upwards from there. 43 Flowering pattern — indeterminate varieties • • 44 Indeterminate varieties begin flowering when less than half the nodes on the main stem have developed.
