Unlocking of Difficulties:
1. Area-the size of the surface area
2. Fertilizer- any material added to the soil to
support nutrient
3. Germination-the development of the seed
into a young plant
4. Graph- a drawing in which the relationship
between two (or more) items of information is
shown in a symbolic way

5. Gross Sales- the equivalent value of the
product sold
6. Interest- the corresponding value that
will be added to the principal as payment
for using money of the lender
7. Labor- the work performed by farmers in
exchange for pay

8. Net Income- the value remains after
all expenses have been deducted from
the gross sales
9. Principal- the amount of money owed
10. Volume- the content of a body or
object

ACRONYMS
1. MAD (Man Animal Day)- the number of
day(s) the work will be completed by 1
person and 1 animal
2. MD (Man Day)- the number of day(s) the
work will be completed by 1 person

Lesson Objectives:
• The students should be able to:
1.Determine the farm inputs,labor
requirements and farm activities.
2.Follow the steps in basic calculation.
3. Calculate the estimate farm inputs and
labor requirements.

ESTIMATING FARM INPUTS
AND LABOR
REQUIREMENTS

• Number of fertilizers per area= 2 bags/ ha.
Total number of areas= 2 ha.
Solution:
• Fertilizer cost= Php1,000/bag x 2 bags/ha. x 2 ha.
• {Fertilizer cost= Php1,000/bag x 2 bags/ha. X 2 ha.
(Cancel similar units)}
(1,000 multiply by 2, and multiply by 2)
Fertilizer cost= Php4,000 (Four thousand pesos)
• Since we are looking for fertilizer cost, the unit should
be in currency (Php, Philippine peso)

ESTIMATE COSTS OF
INSECTICIDES

Formula: Insecticide cost= Price/
insecticide x No. of insecticide/ area x
Total no. of areas
[Read as Insecticide cost is equal to
price per insecticide multiply by
Number of insecticides per area
multiply by Total number of areas]

For example:
Given: Price per insecticide= Php1,000/bottle
(One thousand per bottle)
Number of insecticides per area= 1 bottle/
ha. (One bottle per hectare)
Total number of areas= 2 ha. (Two
hectares)
Solution:
Insecticide cost= Php1,000/bottle x 1

Insecticide cost= Php2,000 (Two
thousand pesos)
• Since we are looking for insecticide cost,
the unit should be in currency (Php,
Philippine peso)

• Estimating irrigation expenses form
planting up to harvest
• Formula: Irrigation expenses= Price of
water/ volume x No. of volumes/day x Total
no. of days
• [Read as Irrigation expenses is equal to
price of water per volume multiply by No. of
volumes per day multiply by Total no. of
days]

For example:
Given: Price of water per volume= Php5/m3 (Five
pesos per cubic meter)
No. of volumes per day= 10m3/day (Ten cubic
meter per day)
Total no. of days= 150days (One hundred fifty
days)
Solution:
Irrigation expenses= Php5/m3 x 10m3/day x 150

(5 multiply by 10, and multiply by
150)
• Irrigation expenses= Php7,500 (Seven
thousand five hundred pesos)
• Since we are looking for irrigation
expenses, the unit should be in currency

Estimating labor cost in
planting

Formula: Labor cost= Labor/day x No.
of days worked
• [Read as Labor cost is equal to Labor
per day multiply by Number of days
worked]

For example:
Given: Labor per day= Php350/day (Three
hundred fifty pesos per day)
Number of days worked= 3days (Three
days)
Solution:
Labor costs= Php350/day x 3 days
{Labor cost= Php350/day x 3 days (Cancel

Labor cost= Php1,050 (One thousand
fifty pesos)
• Since we are looking for labor cost, the
unit should be in currency (Php, Philippine

Estimating labor cost in
harvesting

Direction: Read the farm activities in the box and classify them
by placing into column to which they belong.
Plowing using
tractor
Weeding Threshing rice
Harvesting Applying
fertilizer
Harrowing
using animal
Milling rice Irrigation Storing rice
