TY - THES TY - BOOK T1 - Growth of Jatropha curcas seedlings in different media A1 - Wong, Lee Chiat. LA - English UL - http://discoverylib.upm.edu.my/discovery/Record/509411 AB - Jatropha curcas has been highlighted as energy plant as its seeds can yield oils which can be turned into bio-fuel. The project was carried out to investigate whether the variation in media will have significant effect on the growth of J. curcas seedlings. To date, no documentation has been found regarding this aspect of study. Treatments involved the following media: peat; soil with 66.82% clay; sand; mixed soil 1 (peat: sand=1:1 in v/v) and mixed soil 2 (soil: sand=3:2:1 in v/v/v). The data for the growth variables including height, stem diameter, number of leaves, number of nodes and dry weight were collected monthly for four times. Physical and chemical properties of the media were determined twice at the pre-planting and at final harvest. In addition, the chemical analysis for foliar was conducted encompassing chlorophyll content, nitrate concentration as well as N, P and K concentration. There was no trend for the results of chemical analysis done. The results obtained seems consistent with the hypotheses that variation in media had significant effect on the growth of J. curcas seedlings. The five media (treatments) studied differed significantly for all the growth variables. The findings provide evident that sand was the most favourable medium for the growth of J. curcas seedlings. Sand medium is recommended to the nursery for production of J. curcas seedlings. CN - FP 2007 59 ER -
