| Study on the effectmethod of soil moisture conservation method on yield of Jatropha, variety KUBP78-9 grown on Ultic Paleustalf, was carried out in order to compare the effect of no soil moisture conservation scheme (W1), plant residue mulch (W2), vetiver grass grown between Jatropha rows, slash and mulch (W3), and jack beanast cover crop (W4) on moisture changes within soil profile and yield of Jatropha. Drip irrigation at a rate of twolitres per plant was operated every two days during drought season (Dec 09-May 10). Results indicated that plant residue mulch tended to give the highest seed yield at 15% moisture content (200 kg rai-1) compared to the range of 130.9-145.3 kg rai-1 obtained from other treatments. Growing vetiver grass between rows of... |
