Abstract

Agronomic data from a sample hectare of cotton-growing area of our farm were examined for energy inputs, outputs and balance for comparison with monetary values. Mechanized fanning consumed about 45% of the energy inputs and accounted for about 20% of the expenses. The major cost (53%) was for manpower, which accounted for about 5% of the energy inputs. Irrigation consumed about 30% of the energy inputs but cost only 1%. Fertilizers cost about 6% and accounted for about 12% of energy inputs. Insecticide use consumed under 6% of the energy used but cost about 16%. The total energy inputs were 10,475 Mcal and resulted in an output of 30,107 Mcal, a gain of a factor of 2.87. Cotton sticks provided about double the entire needed energy inputs.
