Is precision Agriculture a vital tool for cassava (Manihot

esculenta)

production in Nigeria?

Tiamiyu adetola

Introduction Migrated to West and central Africa in

the 16th century by Portuguese merchant

Cultivated in Nigeria in the 17th century by emancipated slaves from brazil.

It’s the 2nd staple food after maize.

Production increased from 42% in 1960’s, displacing Brazil.

(Source: FAOSTAT 1996)

Crop description/agronomic Perennial with height of 2-4m. Monocieous with Palmate leaf. Fruit is either oval or triangular

Source IITA 2009

Cultivation Either mono-cropped or intercropped

with maize, cowpea, melon or vegetables.

Propagation solely by stem cutting. Stem cutting are not more than

10mths. Stem cutting are planted vertical, flat

or tilted. Planted on ridge, flat or hillsSource IITA 2009

Benefits and uses Tubers are processed into flour which is

high in carbohydrate. Leaves are used for soup and stews. Stem mainly for propagation. Tuber, Leaves, Stems and Roots are

processed into livestock feeds, starch, chips, pellets, unfermented flour.

Ethanol for bio-fuel, alcoholic beverage and malt drink.

Yield and Yield Potential Based on variety, soil and nutrient

availability yield varies between 18-31.8 Mt/yr.

Model prediction 35.5 – 48.4 Mt/yr.

Fertilizer Requirement In forest with annual rainfall of 500-1755mm

with length of 10mths.• 1st dose 200kg N:P:K 15:15:15 per/ha 4-6wks after

planting.• 2nd dose 100kg muriate of potash 14-16wks after

planting.

In savannah regions with mean annual rainfall of 1000-1500mm in 7mths.

1st dose 200kg N:P:K 15:15:15 per/ha 4-6wks after planting.

• 2nd dose 50kg muriate of potash 14-16wks after planting.

Is P.A a vital tool Maybe! If Greenseeker and pocket sensor are

calibrated for cassava production. NDVI collections to show spatial

variation in field. Active participation of local farmers to

embrace technology. Cost of equipment. Skilled personnel to demonstrate

technology.

Issues

Data management and processing.

Interpretation of data and application of collated data.

Farmers understanding the concept of technology and benefits.

Solution Improved technology skills of farmers. Availability of skilled personnel to

answer questions. Field demonstration of technology. Effective participation of farmers. Involving institute like IITA, because they

convey the message to farmers clearly. Farmers trust the judgment and

technology from IITA.

Alternatives? N- rich strips???

Questions? What is the botanical name of cassava?

Issues with adopting precision agriculture in Nigeria?
