Ruth Otaza Escasinas, R.G Escalada and Raymundo M. Trenuela ABSTRACT Increasing the population density decreased the panicle length, number of grains per panicle, and weight of grains per panicle although it increased the leaf area index. Population density of 200,000 plants/ha gave the highest grain yield of 2.07 t/ha, followed by 300,000 plants/ha at 2.01 …
Monina M. Escalada ABSTRACT All station managers or program directors of radio stations serving the Eastern Visayas were interviewed to determine the rural development (RD) information coverage of their stations. A purposive random sample of 600 radio-listening farmers from 12 municipalities in the Eastern Visayas provided additional data on listenership to RD information. All the …

Jejoma G. Armachuelo and Fernando A. Bernardo ABSTRACT Mutation and other effects of Co60 gamma radiation and ethyl methane sulfonate (EMS) in winged bean were determined at the M1 generation. Seed germination was significantly reduced by irradiation at all levels used but only at 0.15% and above for EMS. Delayed seedling emergence, high lethality and …

Emilia N Bernardo and Nelson M. Esguerra ABSTRACT A satisfactory technique for evaluating cassava accessions/varieties for resisitance to the red spider mites in the field or screenhouse was developed. Of the 295 entries tested, 50 showed varying levels of tolerance to the pest when tested in the field. At a much higher mite population in …
Marissa T. Sabarez, L. M. Ancheta, D. C. Maniwang, S. C. Vencilao and T. J. Fernandez, Jr. ABSTRACT Separate surveys were conducted in Baybay and Ormoc, Leyte to determine the prevalence of liverfluke infestation or fascioliasis and the economic importance of infested livers of slaughtered carabaos and cattle. Results showed that there was no significant …
M. I. Galinato and Percy E. Sajise ABSTRACT Different root crop-growing areas in the Philippines were surveyed during the net season to determine the weed species associated with different root and tubes crops, namely, sweet potato, cassava, yam and white potato. Wet season quantitative vegetation analysis of weed species associated with root crops in the …

Carlos S. de la Cruz, F. L. Loreto and M. K. Palomar ABSTRACT Polybagged sweet potato plants were inoculated with conidia of Cercospora batatae scraped from sweet potato leaves infected with brown leaf spot. The completely randomized design was followed in laying out the experiment. Leaves inoculated at different ages showed varying responses to infection …

Emiliana N. Bernardo and Nelson M. Esguerra ABSTRACT In an unsprayed cassava planting, the cassava red spider mite population fluctuated in lesser magnitude in moderately resistant Accessions 8, 12 and 46 than in Golden Yellow and susceptible Accessions 35, 36 and 38. Irrespective of the susceptibility level, population buildup of the spider mite in ViSCA …

Ofelia P. Ahit, Sergio E. Abit and Manuel B. Posas ABSTRACT Two methods of propagating cassava were compared using 4 levels of fertilizer application. One method was the Mukibat system based on the grafting of Manihot glaziovii with M. esculenta. The other method was the Traditional or the engrafted system using the stalks of the …
Anabella T. Bautista and Rebecco M. Santiago ABSTRACT Both silt loam and sandy loam media were significantly superior than clay loam in enhancing the length of vines and increasing the number of nodes and branches produced on the primary vines of sweet potato plant. Plants grown in silt loam produced the highest average weight of …
