• Akola hoe is drawn by bullocks or hands. It was used to remove the weeds from the field and also used for maintaining the moisture in the field. 

• Thus, the correct option is A.

(A) Dynamometer- It is an instrument/device used for measuring mechanical force or power transmitted by a rotating shaft. For example, it is used to calculate the power produced by a motor or an engine in agricultural fields

Tillage is a method of preparing land for growing the crops. It includes ploughing of land, keeps the land free from weeds, makes the soil leveled, and in preparation of the soil. 

Plough is a tool which is used by the farmers for cultivation of the soil, planting for the sowing of seeds and turning over the soil and cut furrows. Soil turning plows are generally made of iron and is drawn by tractors.                        

So, the correct option is 'High speed'.

Extraction of juice from sugarcane by crushing the cane can be done either by bullock-operated can crusher or in power-operated cane crushers. 60-65% sugarcane juice can be extracted by using bullock-operated cane-crusher.

• Cultivators can be used instead of the hoe. Cultivators are used to stir and pulverize the soil, either before planting (to aerate the soil and prepare a smooth, loose seedbed) or after the crop has begun growing to kill weeds. Unlike a harrow, which disturbs the entire surface of the soil, cultivators are designed to disturb the soil in careful patterns, sparing the crop plants but disrupting the weeds. 

• The advantage of agricultural methods that require repeated ploughing is that they allow mono-cropping on a large scale at remote locations, using industrial machinery rather than human labor.
• Monocropping is the agricultural practice of growing a single crop year after year on the same land, in the absence of rotation through other crops or growing multiple crops on the same land (polyculture). 

• Shaping the soil includes piling soil around the base of plants (hilling), creating narrow furrows (drills) and shallow trenches for planting seeds and bulbs. Weed control with a hoe can be by agitating the surface of the soil or by cutting foliage from the roots and clearing the soil of old roots and crop residues. 

• A ridging plough is used for crops, such as potatoes or scallions, which are grown buried in ridges of soil using a technique called as ridging or hilling. 
• A ridging plough has two mould boards facing away from each other, cutting a deep furrow on each pass, with high ridges either side.
