Abstract
Daily energy demand in Pakistan is increasing due to industrialization and growth in different sectors. Wastage and improper use of energy also exert a high pressure on energy resources and the environment, which can be overcome by discovering new alternative energy resources like biofuels. Therefore, a study was planned to minimize the cost of production through sustainable agronomic approaches to get the maximum biodiesel from castor beans. This investigation was executed by employing a randomized complete block design (RCBD) under factorial arrangements with four phosphorus levels (0, 30, 60, and 90 kg P2O5 ha-1) and two castor bean varieties (NIAB-Gold and DS-30) and replicated three times. Concluding the findings of the study, the highest number of capsules (109.0), the maximum seed yield (1336.00 kg ha-1), the maximum oil percentage (42.45%), and the maximum oil yield (839.0 kg ha-1) were recorded when 60 kg of phosphorus fertilizer were applied in NIAB-Gold as compared to the DS-30 variety. However, DS-30 exhibited the highest oil calorific value (44.0 K j g-1) as compared to NIAB-Gold with respect to combustion of the unit value of fuel. In conclusion, applying 60 kg of phosphorus fertilizer to the NIAB-Gold variety resulted in the highest oil and seed yield, as well as the highest oil content percentage, indicating its potential as a sustainable agronomic approach for maximizing biodiesel production from castor beans.
