Universiti Pertanian Malaysia was established in 1971 as a result of the merger between the College of Agriculture, Malaya and the Faculty of Agriculture, University of Malaya. The Library of the College of Agriculture, Malaya thus became the Universiti Pertanian Malaysia Library. When the university was named as Universiti Putra Malaysia (UPM) in 1997, the Library became the Universiti Putra Malaysia Library. As of 23rd May 2002, the Library has been named as Perpustakaan Sultan Abdul Samad (PSAS), Universiti Putra Malaysia, after the late gre [...]

With effluent application, over an 8-year period, the yields were consistently greater than the control areas which received normal estate inorganic fertilizer. Yield increases of 17 percent, 11 percent and 19 percent were recorded in oil palm, rubber clone PB 86 and RRIM 513, respectively. No apparent adverse effects on crop growth were observed. Soil extractable K, Mg, Ca, P and Zn contents, pH and specific conductivity were higher in effluent-treated that control areas. The contents of these soil chemical parameters decreased with increasing distances from the furrow. Extractable Zn and P tended to accumulate in the top 30 cm of the soil. Extractable Ca and mg varied slightly while K increased with soil depth. Site monitoring of the effluent application scheme using tubewell and river water indicated negligible impact on water quality. An economic analysis of effluent application to oil palm showed that savings ranging from $58 to $236 per ha per yr could be realized when the rubber factory effluent was applied at 23cm to 11.5cm rey, respectively
