考虑到为印度的Jetropha种植园抽出地下水所需的能源，已经对Jetropha种植园由于灌溉而增加的产量进行了调查。地下水位的深度是变量。与未经灌溉的水树种植进行了比较，并将生物柴油产量的增加与运行水泵所需的一次能源进行了比较。对降水少、中、多、埋深分别为20m、40m、60m的地区进行了分析，发现在降水少、地下水位40m的地区，前4年能量平衡为负平衡。而降水少但地下水位20m的地区，能量平衡在第3年转为正平衡，而对于60m深度，能量平衡甚至在第5年也不转为正平衡。
Increase in yield of Jetropha plantation due to irrigation has been investigated considering the energy required to pump out underground water for Jetropha plantation in India. Depth of the water table is the variable. Comparison has been made with unirrigated Jetropha cultivation and increase in yield of bio-diesel has been compared with the primary energy required for operating the water pumps. Analysis has been carried out for areas having low, medium and high rainfalls and with three depths of water tables 20 m, 40 m and 60 m. It has been found that in areas having low rainfall and depth of water table 40 m, the energy balance is negative for first 4 years. Whereas in areas having low rainfall but water table 20 m, energy balance becomes positive in the third year, whereas for 60m depth, it doesn’t become positive in the fifth year even.
