Ten Guntha sustaining farming

Scientific reason for Ten Guntha.
1 One man needs 2500 Kilo Cal.
2 Solar energy gives 1250 Kilo Cal per Sq. ft. Per day eight hours.
3 Matured green leaves harvest only 1% of it.
4 So 100 sq. ft. for one meal.
5 We need food as well as some firewood, cloth, oil etc. it comes to 1400 Sq.ft.
We live in a family of five members per family so 7000 Sq.ft
6 We also need shelter and water each requires 1000 Sq.ft.
7 Storing place and free place for play 500 Sq.ft. for each Total 10,000.

Basic requirement of Human:
Food consumption should be 2500 calories/day/person. It is expected that a person will get: -
Protein 75gms. Carbohydrates 300gms. -Fats 75gms. Other 200gms.
(Includes vegetables basically) from diet.

What we get from 10 Guntha Natueco farming:
Ten Guntha Natueco farming system can fulfill the daily requirement of family.
In addition to above, 5kg. of fuel oil for transportation, surplus vegetable for cash,
The requirement of 5kg of fuel wood per day per family for cooking will be ensured. If we now multiply bye a factor 2 to cover other than food expenses, we get our requirement per family of five for one year as under. Cereals approx 2 tons, Oil seeds approx. 350 kg. Pulses approx. 250 kg.12 trees of banana @ 150 banana per tree per year give 1800. 1800 divided by 365 will give 5 banana. Normally for general planning a requirement on a flat basis of 600 gm. per day per person is assumed.
This works out to 0. 600 gm. X 5 x 365 = 1095 kg. X 2 = 2.19 tones.
Our production will be 1gm.dry weight Per day so seven Guntha will produce 1gm into 7000 Sq.ft. i.e.7Kg. Per day i.e. 7 x 300 days will produce 2100 Kg. Per annum i.e. three ton approximately per annum which include fresh weight. It shows that 900 Kg. will be surplus. In second and third year plantation will take two to four tier and production will increase to five tons and surplus will be saving.
