Farm Mechanization Concepts Quiz

Farm Mechanization Concepts

• A 1000 kg carabao traveling at a certain speed can pull a moldboard plow with specified dimensions and soil draft.
• Soil draft is measured in kg/sq.cm., and the question relates to pull calculations in terms of standard working days (swd).

Time for Plowing Fields

• The time taken to plow a rectangular field depends on its dimensions (length and width) and the speed (VW) of the pulling mechanism, represented as LW / 10 VW.

Weight and Pull Relationship

• An increase in the carabao's weight from 1000 kg to 1500 kg does not affect total pull percentage-wise; the correct answer denotes no increase (0%).

Overlapping Passes in Plowing

• Overlap during plowing affects the required time, determining that if passes overlap by 10%, the calculation changes to LW / 90 VW for time estimation.

Harvesting Rice Fields

• For a two-hectare rice field with the length twice the width, a stripper combine achieves a harvesting speed of 5 kph.
• A field sampling indicates a yield of 0.60 kg of paddy per sq.meter, with the area completed in two hours.

Swath Width and Yield Calculations

• Multiple possible answers exist for the swath width of the combine, highlighting its variability across different units (meters, inches, yards).
• The total yield from the 2-hectare field based on sampling is expressed in various units, confirming conversions such as 423,288 ounces and 26,840 lbs.

Spraying Techniques

• A 6-nozzle boom sprayer requires specific mounting adjustments to prevent spray overlap, calculated based on nozzle arrangement and spray angle.
• The nozzles are arranged 150 cm apart with a 60-degree spray angle, posing considerations for effective height relative to a 50 cm rice plant canopy. The height needed to avoid overlap is 180 cm.

Effective Swath of Boom Sprayer

• For optimal application, the effective swath width of the boom sprayer must be determined under specified conditions from previous calculations.
