Lucia M. Borines, Elsie E. Salamat and Rammel B. Cardines ABSTRACT Fusarium wilt caused by Fusarium oxysporum f.sp. cubense (FOC) is one of the problem diseases attacking abaca. The most effective way of minimizing the damage is through the use of resistant varieties. The levels of resistance of different abaca varieties/accessions, however, have not been …
Arturo E. Pasa ABSTRACT The study assessed the carbon stocks or storage within the Community-Based Forest Management (CBFM) Project in Midwestern Leyte Province. The CBFM project area stored an average carbon density of 333 Mg/ha from aboveground biomass down to the soil complex (0-1m depth). The upperstorey biomass has an average carbon density of 166 …
Rosalina D. Poliquit1 and Misael T. Diputado, Jr.2 ABSTRACT An experiment was conducted to evaluate the influence of rate and time of application of chlorophenoxyacetic acid (CPA) on the fruit set, yield and quality of tomato (variety, Improved Pope) The application of CPA enhanced fruit set, reduced the number of days to fruit maturity and …

Zosimo S. de la Rosa, Jr. and Marilyn M. Belarmino ABSTRACT The utilization of nodal stem cuttings containing dormant axillary buds as explants for plant production of two rose species; Rosa chinensis cv. ‘Old Blush’ and R. centifolia cv. ‘Petite de Hollande’ was demonstrated in this study. This propagation technique required the breaking of dormant …
