Spraying Done By Manual Process : Amount paid to the labor for one day = Rs. 500 per labor Total number of labor required in general to spray 1 Ac = 4 Total amount paid to the labour = 4*500 = Rs. 2000/ day / acre Therefore, Total expenditure in one day is = Rs. 2000 Spraying Done By Battery Machine: Consumption of electricity required for 1 acre = 6 units Cost of electricity per unit = Rs. 7 Total cost of petrol for 1 acre farm for a day = 6*7 = Rs. 42 Amount paid to the labor = Rs. 500 per day Total expenditure = Total cost of electricity + Amount paid to the labor = Rs. 42 + Rs. 500 + Rs. 30 = Rs. 572 ~ Rs. 580 Amount saved by using the automatic removal machine = Rs. 2000 – Rs. 580 = Rs. 1420 / day / acre Spraying done by Pneumatic Sprayers Amount paid for labor for spraying 1 acre = Rs. 500 Amount spent for spraying the 1 acre by = manpower + maintenance = 0 + 100 = Rs. 100 Amount saved by Automatic spraying machine = Rs. 500 – Rs. 100 = Rs. 400 OTHER TIMING AND SPRAYERS CALCULATIONS…
