Master of Science in Agronomy. Don Mariano Marcos Memorial State University, North La Union Campus, College of Graduate Studies, Bacnotan, La Union. Adviser: Analyn V. Sagun, Ph.D. The production of vegetable soybean is an important aspect of agriculture in addressing malnutrition and potential solution against poverty and hunger. This study was conducted to (1) determine the performance of four varieties of vegetable soybean (V1: PSB Sy 02 (Tiwala 6), V2: Select Tudela Black, V3: Select Manchuria, V4: NSIC Sy 12 (Tiwala 14); (2) to find out the influence of varying fertilization scheme ( F1: Organic fertilizer, F2: Organic fertilizer + Inorganic fertilizer (T14), F3: Organic fertilizer + Gypsum) (3) their interaction effects and (4) to assess the cost and return analysis of vegetable soybean production. Results of the study showed that the growth and yield of four varieties of soybean vegetable performed differently in all the parameters tested. PSB Sy 02 (Tiwala 6) performed the tallest (131.87 cm), higher number of active root nodules (24.35), heavier biomass (1,234 grams), pod yield (2,041 kilograms) and seed yield (1,111 kilograms) while on the varying fertilization scheme did not significantly affect the performance of the four varieties of soybean except the shelling percentage. Comparable results were observed on the interaction effect of varieties fertilization scheme except on plant height and shelling percentage. Variety Select Tudela Black did bear flower but did not produce pod. PSB Sy 02 (Tiwala 6) applied with Organic fertilizer (V1F1) treatment combination is the best recommendation to attain highest Return on Investment (ROI) of 191.93% on vegetable soybean production. | |
