Victorio A. Perez and Merle B. Shepard ABSTRACT Telenomus triptus (Nixon) (Hymenoptera: Scelionidae) is an efficient egg parasitoid of the Malayan black bug (MBB) Scotinophara coarctata (Fab.) (Hemiptera: Pentatomidae), a serious pest of rice in Palawan Island, Philippines. The success in mass rearing T. triptus is dependent on the availability of MBB eggs. The study …
Roberta D. Lauzon and Akiko Kawabata ABSTRACT Starch was produced from red and white cocoyams following the method developed by the Food Science Section of the Department of Agricultural Chemistry and Food Science (DAC-FS), VisCa, Baybay, Leyte. Purified starch sample were used in the analytical works. Granular size districbution and x-ray diffraction pattern determination were …
Villaluz Z. Acedo ABSTRACT The solidified Murashige and Skoog (MS) medium added with gibberellic acid (GA3) induced direct organogenesis without any callus formation of the meristems of sweetpotato, varieties VSP-1, VSP-2 and VSP-3. The optimum GA3 concentration varied with variety. On the other hand, benzylaminopurine as medium supplement caused profuse callus growth on the basal …

Cristina E. Sajise and Carlito Palermo ABSTRACT Sweetpotato genotypes were screened for resistence to Botryodiplodia theobromae Pat. and Macrophomina phaseolina Tassi, the two major postharvest pathogens found infecting sweetpotato roots during storage in the Philippines. The effect of different stages of maturity of sweetpotato plants on host resistance and the nature of postharvest disease development …
Tessie C. Nunez and Ricardo P. Bales ABSTRACT Seven dwarf coconut cultivars which were subjected to different levels of ammonium sulfate and potassium chloride application responded similarly to fertilization. Fertilization generally improved the growth and precocity of these cultivars with the fertilized palms developing bigger girths, taller stand and retaining more functional leaves than the …
Luvimin A. Evangelio and Elpidio L. Rosario ABSTRACT Sweet corn and sweet potato were grown under 13 different cropping treatments. Double rows spaced at 0.3 m with interval row spacing of 1.0 m appeared to be the optimum treatment combination with a mean yield of 21.99 t/ha. Under this scheme, yield increases of 75% and …
Myrna M. Avila ABSTRACT A total of 175 corn farmers in the three provinces of Region XI were personally interviewed with the use of an interview schedule. Of the nine recommended corn production practices, the farmers had high adoption rate in six, namely: seed treatment, weed control, thinning, distancing of plants, insect control, and application …
E.A. Lopez, R.M. Gapasin and M.K Palomar ABSTRACT Low population density of Helicotylenchus stimulated plant growth. Weights of tops, roots and tubers at a population of approximately 1,000 nematodes per plant were higher than those of the control. Plant growth was not retarded at low levels of nematode population. However, as the population was increased …
R.P Bales, R.N. Santiago and N.M Gloria ABSTRACT The 10 abaca varieties significantly differed in almost all of the parameters considered. Lawaan x Tangongon had the heaviest weight of fresh stalk and tuxies in the outer and middle groups of leafsheaths, produced the highest weight of dry fiber recovered, and ranked second in terms of …
