Harvest Season: Limited production can be expected in the second harvest season, and full production in th< third to fourth season. Red raspberries yielc rom 3,000 to 3,500 quarts per acre, and black orts from 4,000 to 4,500 quarts per acre. De-ending on the grower's skill, profitable produc-ion should be expected for 10 years or more.
It responds well to liberal applications of manure in the fall. The plants should be set three feet apart each way. Harvest of the stalks may begin when the plants are two years old, and the stalks should be pulled, not cut. Roots of rhubarb should be divided every three or four years. For forcing, the roots are dug in fall, allowed to freeze, taken indoors, covered with soil or sand, kept in the dark or in dim light, and watered occasionally. The crop will be ready in about six weeks. After the harvest, the roots are thrown away.
Savanna grass-ind develops in regions of high temperature that ave a distinct wet and dry season. Growth is ipid in the wet season, but the plants become ry and low in quality in the dry season. Widely >aced drought-resistant trees may occur in some
•eas such as in the savanna parklands of Africa id Australia. Savannas are subject to flooding i the wet season and to extensive burning in le dry season. These grasslands are heavily•azed by large numbers of cattle. Major prob-ms are poor grass quality in the dry season, irasites, and disease. The tsetse fly is a major•oblem in Africa. There are no true savannas North America.
