M.C. Escalante, H.P. Johnson and C. Anderson ABSTRACT An irrigation water management computer simulation model for lowland rice production was developed using the concept of rotation irrigation. It was designed so that the number of rotation areas and Interval of irrigation could be varied within the program. Input parameters Included maximum irrigable area, variety of […]

Andres L. Alemania, R.M. Santiago and N.M. Gloria ABSTRACT Three abaca varieties (Linawaan, inosa and Laylay) were evaluated for fiber quality and recovery. Except for stretch percentage, Llnawaan variety showed the highest recovery and tensile strength, and the heaviest taxies and dry fiber recovered per stalk. However, Laylay variety produced more fiber of higher grade

Angela S. Almendras, Reynaldo E. dela Cruz and lreneo J. Manguiat ABSTRACT The response of cassava (cv. Laken) to NPK fertilization and mycorrhizal inoculation was evaluated through a pot experiment using unsterilized soil (Lipa clay loam and Luislana clay). Application of 45-60-60 and 90-60-60 in Lipa clay loam and Luislane clay, respectively, resulted in significantly

Justiniano L. Seroy ABSTRACT The students’ oral narrations on 3 picture stories were tape-recorded. Background questionnaires were administered to the students, and the comprehensibility of the English oral narrations were evaluated by 18 selected judges. Analysis of the data revealed that a) the students widely employed communication strategies in their oral narrations; b) the mean

BeniIda S. Pestilos and Monina M. Escalada ABSTRACT The Farm Management Technicians involved In Maisagana or corn production program in Leyte who served as respondents had ages ranging from 22 to 41 years with a mean age of 28.9. Majority were males and married. All of them completed a bachelor’s degree, one-half of whom majored

Jose L. Bacusmo and A. L. Carpena ABSTRACT Leaf area index, crop growth rate, leaf angle of young leaves, internode length, number of roots per plant and mean root weight showed a positive correlation with root yield. Specific leaf weights, net assimilation rate at 30 and 60 days after planting and moisture content showed negative

Luz A. Devaras, Rodolfo G. Escalada and Bernadette F. Quirol ABSTRACT Fly ash application at the rate of 5 t/ha enhanced early our bulking, resulting in the development of more tubers per plant of sweet potato. Application of higher levels of fly ash did not increase its tuber yield but promoted the vegetative growth of

Celsa F. Armecin and Azucena L. Carpena ABSTRACT The prevalence of normal bivalent pairing at diakinesis and metaphase I and the high percentage of cells having regular meiosis suggest that cassava (Manihot esculenta Crantz) is an allotetraploid and not an autotetraploid. Based on the results, cassava seems to be a segmental rather than a true

Rolinda L. Talatala ABSTRACT The phytotoxicity of thiobencarb (S-4-chlorobenzyl diethylthiocarbamate) to IR-36 and RD-19 rice cultivars using different methods of NA (1. 8-naphthalic anhydride) application was evaluated under greenhouse conditions. IR-36 cultivar showed greater response to the method of NA application than RD-19. Seed treatment with the antidote provided the best protection to IR-36 seedlings.
