The objectives of a tree breeding program range from yield improvement and adaptation to particular conditions, to pest- and disease-resistance, wood properties, etc.

Research has shown that peer-run self-help groups yield improvement in psychiatric symptoms resulting in decreased hospitalization, larger social support networks and enhanced self-esteem and social functioning.

After 1955 however, there was a dramatic ten-fold increase in the rate of wheat yield improvement per year, and this became the major factor allowing global wheat production to increase.

Revenues for the year rose by 1.3 per cent to 9.3 billion through pricing, yield improvements and the effect of foreign exchange.

The stadium project also yielded improvements to the multi-purpose room.
