Question 1 Report

In a tabular form, discuss cocoa, yam and millet production under the following sub-headings: (a) climatic requirement; (b) soil requirement; (c) cultural practices; (d) method of propagation.

Answer

Crop	Climatic Requirement	Soil Requirement	Cultural Practices	Method of Propagation
Cocoa	Warm and humid climate, well-distributed rainfall of 1500-2000mm per year, and an annual temperature range of 21°C to 32°C	Well-drained, deep, sandy loam, or clay-loam soil with a pH of 5.5-7.0	Shade is required, as well as regular pruning and weeding.	Propagation is by seeds or vegetative means, such as cuttings, budding or grafting.
Yam	Warm and humid climate, with an evenly distributed rainfall of 1200-1500mm per year, and a temperature range of 25°C to 30°C.	Deep, well-drained, loamy soil with good water holding capacity, pH range of 5.0-6.5, and rich in organic matter.	Land is cleared, mounds are constructed, stakes are driven into the mounds, and the yam setts are planted on top of the mounds. Weeding and mulching are necessary to prevent competition with weeds.	Propagation is by tubers or sets, which are cut into small pieces with a bud for planting.
Millet	Warm and dry climate, with rainfall of 400-600mm per year, and a temperature range of 25°C to 35°C.	Sandy loam soils with low fertility, good drainage, and pH range of 5.0-7.5.	Adequate land preparation, timely planting, and weed control are necessary.	Propagation is by seeds, which are sown directly into the soil.

Explanation:

Cocoa, yam, and millet are all important crops in Nigeria, with different climatic and soil requirements, cultural practices, and methods of propagation.

Cocoa requires a warm and humid climate with a well-distributed rainfall of 1500-2000mm per year and an annual temperature range of 21°C to 32°C. The crop is best grown in well-drained, deep, sandy loam or clay-loam soil with a pH of 5.5-7.0. Shade is required, as well as regular pruning and weeding. Propagation is by seeds or vegetative means, such as cuttings, budding or grafting.

Yam requires a warm and humid climate with an evenly distributed rainfall of 1200-1500mm per year and a temperature range of 25°C to 30°C. The crop grows best in deep, well-drained, loamy soil with good water holding capacity, pH range of 5.0-6.5, and rich in organic matter. Cultural practices include land clearing, mound construction, planting of stakes, planting of yam setts, and regular weeding and
