One of the major positive attributes of cassava is that it does not have a specific harvesting period. Roots may be harvested any time between six months and two years after planting.During periods of food shortage, they can be harvested whenever needed, often one plant – or even one root – at a time. For human consumption, harvesting usually takes place at about 8 to 10 months; for industrial uses, a longer growing period generally produces a higher root and starch yield. Once harvested, roots can be consumed directly by the farm household through cassava milling machine , fed to livestock or sold for processing into a wide array of value-added products, ranging from coarse flour to high-tech modified starch gels. The root is not the only part of the plant that can be put to good use. In Africa, cassava leaves are cooked as a vegetable. In many countries, the green part of the upper stem, including leaves and petioles, are fed to cattle and buffaloes, while the leaf-blades are fed to pigs and chickens. In China, Thailand and Viet Nam, fresh leaves are used for raising silkworms. Stumps are burned as fuelwood, and woody stems are ground-up and used as a substrate for growing mushrooms. Harvesting Cassava Roots and Plant Tops Cassava roots are generally harvested by cutting off the stems about 20 cm above ground, then lifting the whole root system out of the ground by pulling on the stump. If the soil is too hard or the roots are too deep, it may be necessary to dig around the roots with a hoe, spade or pick to remove the soil, avoiding damage to the roots in the process. To harvest their cassava, Thai farmers have developed a metal tool that is attached to a pole and used as a lever. It works best in loose or light-textured soils. In heavier soils, which can become very hard in the dry season, a harvesting blade attached to a tractor is sometimes used. The blade cuts through the soil just below the roots and the forward movement of the tractor pushes the root clumps to the surface. The roots are then cut from the stump and placed in baskets or sacks for transport.The the cassava will be processed by cassava chipper machine. After the root harvest, plant tops are often left to dry on the ground and later incorporated in the soil to help maintain its fertility. However, farmers can greatly increase the total amount of cassava foliage available for feeding to animals by cutting the green tops every 2.5 to 3 months during the plant’s growth cycle. After each pruning, the remaining stems will sprout again and produce another crop of leaves within 2 to 3 months. For maximum foliage production, cassava stakes should be planted with closer spacing, of about 60 x 60 cm. Young leaves harvested at regular intervals during the cassava growth cycle tend to have a higher protein and lower fibre content than those collected at the final root harvest, when plants are normally 11 to 12 months old. The younger leaves are more palatable and provide a higher quality feed. Similarly, leaf meal containing only leaf-blades has a higher protein and lower fibre content than meal that also contains petioles and green stems. In an experiment in Thailand, total dry leaf yield was 710 kg per hectare when leaves were harvested only at the time of root harvest, at 11.5 months after planting. But the yield increased to 2.6 tonnes when leaves were cut five times during the same period. The total leaf protein yield also increased, from 170 kg with only one leaf harvest to 650 kg, similar to a good crop of soybeans. However, as the frequency of leaf cutting increased, the final root yield dropped, from around 40 tonnes per ha when leaves were harvested only at the time of the root harvest, to less than 25 tonnes when leaves were harvested a total of five times. Depending on the cost of labour and the relative prices of fresh roots and dry leaves, this system may or may not be economic. Harvesting the plant tops 4 or 5 times during a one-year growth cycle also removes a large amount of nutrients – especially nitrogen –from the field, and would not be sustainable without the application of large amounts of mineral fertilizer to maintain soil fertility. Food for Direct Consumption Young cassava leaves are regularly picked and cooked for human consumption in several African countries, notably Cameroon, the Democratic Republic of the Congo, Liberia and the United Republic of Tanzania. The tender leaves contain up to 25 percent protein, on a dry matter basis, and are a valuable source of iron, calcium, and vitamins A and C3. The essential amino acid content of cassava leaf protein is similar to that found in a hen’s egg. The market value of cassava leaves in areas where they are consumed is often higher than that of the roots, indicating that their sale contributes significantly to farm household incomes.
