Explain seven factors that determine the choice of implements for primary cultivation

Explain seven factors that determine the choice of implements for primary cultivation

Answers

john
i) Topography of the land: where land is too steep, a jembe is more appropriate than a tractor-drawn plough.

ii) Condition of the land: a forked jembe or disc plough is more appropriate on land that is stony, stumpy and has rhizomatous weeds than a jembe or mould board plough.

iii) Soil type: heavy soils require heavier implements than lighter soils

iv) Depth of cultivation desired: where deep digging is required heavy tractor – drawn ploughs and sub soilers are more appropriate than lighter ox-drawn ploughs and jembes.

v) Cost of the implement and the capital available; the cost of certain implements may be prohibitive to use.

vi) Skill or know-how required; most tractor drawn implements need special skills to operate as opposed to simple hand tools.

vii) Type of tilth required: a disc plough leaves a rough seedbed compared to a mould board plough. A rotavator may provide a finer tilth.

viii) The availability and accessibility of the implements; those that are not easily available may be expensive to acquire.
