Tomas D. Cardona and Alan L. Presbitero ABSTRACT The proctor densities of Umingan clay loam, Maasin clay and Malitbog clay were 1,489.48, 1,444.61 and 1,527.49 kg/m3, respectively at the optimum soil moisture content of 25%, dry basis. These values are statistically different at 1% level based on Scheffe’s test. Keywords: Proctor density. Optimum moisture content. …

Leonila S. Parilla, Oscar B. Posas and Rowena M. Ampong ABSTRACT The average mild and cheese production was significantly higher in treated caracows than in untreated ones due to the increase in the protein intake of the treated animals thus increasing the solid content of the milk. Gathering and feedling ipil-ipil leaves to caracows, milking …

Federico G. Villamayor, Jr. and Rudy D. Perez ABSTRACT The effect of topping on storage root and apical stem cutting production of a bush sweet potato cultivar (VSP-2) was studied. In the first experiment, all terminal cuttings at least 16 cm long were cut either at 38, 45, 52, or 59 days after planting (DAP). …

Crisanta E. Sajise ABSTRACT This study was undertaken to determine the effect of host genotype, inoculum density and plant age on the severity of Fusarium root and stem rot in cowpea (Vigna unguiculata). Different levels of Fusarium solani inculum, namely: 8 x 104, 2 x 106 and 4 x 108 conidia/mL were inoculated to 5-, …

Manuel K. Palomar and Mario A. Martinez ABSTRACT PRC 24 cassava plants inoculated with Cercospora henningsii at 8 weeks after planting manifested the earliest symptom and defoliation. Initial symptoms of cassava brown leaf spot disease are light green, round lesions about 3.5 mm in diameter which later turn greenish brown. These lesions then coalesce and …
