Victor B. Asio ABSTRACT The optimum time for fermentation and suitable fermenting container was established for the production of sweetpotato-based fermented beverage. Evaluation of the beverage was done through physicochemical and sensory analyses by trained panelists. The acceptability score in terms of flavor and general acceptability of 8-day fermented beverage was the same as the …

E.M. Masamayor and R.D. Lauzon ABSTRACT Peanut milk is white with a “nutty” odor. Other physico-chemical properties included a pH of 6.53, viscosity of 10cps, 7% TSS, 1.57% TTA, 5.52% protein, 16.42% fat and 72.4% moisture. Substituting commercial milk with peanut milk does not significantly alter the sensory qualities of yoghurt. Sensory qualities of peanut …

Julie D. Tan and Edna E. Forio ABSTRACT The suitability of sweetpotato for pickling was investigated. The use of law salt (LS) and high salt (H) was tried in the curing process. LS was found to be an effective method for curing sweetpotato. This process was further improved by heat and chemical treatments and reduction …

J.R. Pardales, Jr. and C.B. Esquibel ABSTRACT The effect of selected cultural practices on the adventitious root development in the stem cuttings of sweetpotato [Ipomoea batatas (L.) Lam.] was investigated through pot experiments. Storing apical stem cuttings for at least 3 days under ambient condition markedly increased the number and total length of the adventitious …

M.L.A Dioquino, E.R. Alcober and A.D. Ramos ABSTRACT Shading (80% reduction of full sunlight) did not significantly influence the early growth of mango seedlings (var. Carabao) grown in six potting media preparations. Potting media, however, significantly affected the stem height and diameter, leaf number and size and seedling vigor. Seedlings grown in pure garden soil …

Victor B. Asio ABSTRACT Osmoconditioning using polyethylene glycol (PEG) ‘6000’ solution restored the germination capacity of sweet pepper seeds subjected to accelerated ageing treatment to the level of the germination time and speed of germination capacity of fresh seeds. It also enhanced uniformity of germination time and speed of germination and seedling emergence of the …

Marilyn M. Belarmino and Darlyn B. Posas ABSTRACT A system for in vitro propagation of pummelo or Citrus maxima (Burm) Merr. Was established using shoot tip and single-node stem segment taken from young seedlings. The procedure involved the initiation of shoots from explant tissue, followed by shoot proliferation, >in vitro rooting, and finally, hardening of …

Victor B. Asio ABSTRACT Upland agriculture in the Philippines, which started in the Neolithic Age, has evolved from an environmentally-sound traditional shifting cultivation into a destructive form of agriculture. Population which increased from about 7 million at the turn of the century to 70 million at present, is considered as a major factor behind this …
