"Studies on the Preparation of Protein Hydrolyzate from Coconut and Soybean Meals"
This study was conducted to determine the effect of temperature, reaction time, and type and concentration of acid on the hydrolysis of coconut and soybean meals. Release of free amino nitrogen from peptide bonds was used as a measure of... Read more.MS (University of the Philippines Los Baños)"Supply Response of Corn to Price in the Philippines, 1957-1974"
The study involved a test of major hypothesis about the economic behavior of Philippine corn producers. Supply response functions were estimated to test whether corn producers respond rationally, in terms of quantity produced and area planted, to...

The photosynthetic rate water hyacinth plants was measured with the use of URAS infra red gas analyzer at constant CO2 concentration of 400 ppm, 25°C and 70% relative humidity. The photosynthetic rate was found to vary from 1.61 to 15.52 mg...

The effect of shower frequency on the reproductive performance and physiological responses was investigated in 32 seven-month-old crossbred gilts. The animals were divided into four treatment groups composed of no shower, shower once, shower...

The study sought to determine the effect of hulling, cooking time and fermentation time on the quality of soymilk. Results showed that total protein content, amino acid nitrogen viscosity, pH of soymilk before and after processing and...

The mosaic type of corn disease in the Philippines was found to be caused by two distinct plant viruses. One was a flexible rod-like virus transmitted by five species of aphids in a nonpersistent manner, while the other was a bullet- or...

Field experiments were conducted in the dry and wet seasons to study the physiological responses to varying plant populations and row spacings of rice and corn in mono culture and intercrop plantings. In the dry-season intercrops, rice decreased... Read more.PhD in Agronomy (University of the Philippines Los Baños)
