Energy Bill on Cassava Production Under Barangay Kandaga, Talipao, Sulu Condition, Philippines
Keywords:energy inputs, energy hotspot, net energy, total energy inputs
The aim of the research is to gather findings on the energy bill of one of the important crop or commodity in the Province, in the Philippines as well as worldwide, it is situated at approximately 5.9930, 121.1035, in the island of Jolo. Elevation at these coordinates is estimated at 143.4 meters or 470.5 feet above mean sea level and 23 kilometers away from the down town of Jolo, Sulu. The information produced could be of great help to the local and national government with the collaboration of the different sectors for possible implementation of agricultural policy that lead to more efficient energy usage. The total energy inputs on cassava production at 2,273.41 Mcal ha-1 (199.18 LDOE ha-1). Lowest energy inputs is obtained by harvest and pre-harvest activities with 629.25 Mcal ha-1 (55.13 LDOE ha-1), of this total, DEI, IEI, EEI contributed 93.19%, 6.26%, 0.56%, while the Crop Establishment at 814.51 Mcal ha-1 (71.36 LDOE ha-1), the DEI, IEI, EEI contributed 4.65%, 0.54%, 56.51, 38.84%, the pre-land Preparation got the highest energy inputs at 829.65 Mcal ha-1 (72.69 LDOE ha-1), of this total, DEI, IEI, EEI contributed 62.15%, 37.46%, 0.40%, Within the whole activity in cassava production, the value for DEI, IEI, EEI ranged from 0.56% - 93.19%, 4.65% - 56.51%, 0.40% - 62.15%, respectively. The harvest and pre-harvest activity obtained the EnROEI of 5.06 Mcal ha-1. The energy hotspot was obtained by the direct energy inputs. Pre-land preparation obtained 62.15% energy share, while hauling and transport activity marked as the energy hotspot among activities with 93.19% energy share. With the energy productivity (EP) of 6.68Mcal ha-1, and obtained the net energy (NE) of 13,136.59Mcal ha-1. The high net energy was attributed by high energy output and low in energy inputs. Among the entire activities on cassava production the crop management obtained no data this was due to no activities implemented on these particular activities such as application of insecticide, fungicide and herbicide.
