Cassava crop is very important to Tanzania, especially to low-income farmers. Most farmers mix cassava with other crops such as legumes, peas
,
chief, etc. The importance of this crop is to provide us with food and sometimes for business. In the southern region cassava is a staple food that accounts for 75% of the food for all coastal regions.

Cassava thrives well in areas located at 0 - 1500 meters from sea level. Cassava also thrives in areas with an average rainfall of 750 mm - 1200 mm per year. Cassava thrives on sandy soil. The cassava crop is very popular for drought tolerance.

TECHNICAL TECHNOLOGY
The best cassava seeds
To date there are two types of quality seed certified by farmers. These seeds tolerate diseases (both pests and acne), and they are very fertile in comparison to traditional seeds.
I continued to grow 19 tonnes per hectare, and can be harvested from 9 months from planting.

Swim
It yields 25 - 30 tons per hectare, and can be harvested from 9 months from planting.

Best practices for cassava farming

Field preparation
The field should be prepared before the start of the season. The preparation of an ideal farm follows the following steps:
- Slash field
- Shaving and burning stems
- Cultivation and maintenance of terraces
· Choosing the best seeds to plant
Seeds should be free of any stems, so choose stems that are well matured.
· Canadianization

There are three ways to grow cassava:
- Horizontal
- Vertcal stabilization
- Stretching (Inclined / Slunted)

Length of plant stem:
 It is recommended that the height be 30 cm; but the height of the climbing phase depends largely on the number of eyes on the piece, it is advisable to keep the eye open (4 - 6).

Space to climb:
For planting cassava, the stem from the stem is 1 m and the row to row is 1 m. For mixed and other crops, it depends on the crop that is mixed; row to row is 2 meters - 4 meters and the stem to stem is 1 meter.


 Weeds:
- The first weeding should be done early (1 month) after planting to avoid weeds sprouting immediately after rainfall. Within the first four months cassava should not have weeds in order to avoid competition for essential nutrients (light, fertilizer, water, etc.) between the cassava and the weeds.
- Weeding is done by using a handgun or herbicide.
- Sometimes weed control can be done using leaves to be spread over the soil.
- Plants take place 2 to 3 times until maturity.

Harvesting:
Cassava can begin to be harvested after 9 - 12 months after planting. It is advisable to harvest at sunset; since during the rainy season the amount of carbohydrates in cassava decreases.

Excellent processing
The best cassava processing is done for two main reasons:
- Simplify / speed up glazing
- Removal of cyanide poisoning from certain types of cassava
- Increase the quality of the cassava meal itself.

Best methods of processing
- Using a Grater type machine
This produces soft cassava cells, which are subsequently cut using another device called a presser to get rid of the poison in the cassava. This machine is used mainly for bitter cassava.
- Using a chipper machine
- This machine produces small pieces (chips). This machine is used mainly for sweet / cold cassava.

Gambling Use
- Cassava can be cooked on its own as a meal or to make a meal
- cassava flour can make sticky items made from whole wheat flour such as biscuits, chapatti, peas, chili, cakes, etc.
- Cassava can also be used in industrial production of other products such as starch.


iii VEHICLES AND PATIENTS
· Diseases
There are two diseases that are very important and limit the production of cassava.
a) Malaria or brown blood disease
      in cassava
  The disease is most prominent in areas with altitudes less than 300 meters and is found very slowly at altitudes of 500 meters and beyond where its normal distribution is completely absent.

Causes:
The results of preliminary studies indicate that the disease was transmitted by a white or flyfly with a small wingspan.

Symptoms of Illness
All parts of cassava may show symptoms of the disease but what are the features of the disease and to what extent they depend on the environment, the stage of growth of the plant by comparison.

On the leaves
Symptom 1: Chlorosis, yellow pigment occurs first around the small vein and then covers the smallest vein and can become a yellow spot (chlorosis).
Symptom: A yellow color that is not well associated with the vein except in a circular vein between the main veins at the later stages of the disease.
