SOYBEAN PRODUCTION
UNDER CONVENTIONAL, ORGANIC
AND ZERO FERTILIZATION SCHEMES
Introduction
• Soybean (Glycine max)
• known in the world as “wonder crop” of the 20th
century
• one of the most versatile high value crops
Introduction
• Domestic soybean production - Southern Mindanao,
CARAGA, Central Visayas, and Cagayan Valley
• Domestic requirement for whole soybean - met
largely by importation
Objectives
- To determine the adaptability of Tiwala 6, Tiwala 8, and Manchuria varieties in Indang, Cavite
- To evaluate the response of Tiwala 6, Tiwala 8, and Manchuria to conventional, organic and zero fertilization
- To assess the profitability of Tiwala 6, Tiwala 8, and Manchuria variety as affected by fertilization scheme

Conclusions
1. PSB Sy-2 (Tiwala 6), PSB Sy-6 (Tiwala 8) and Manchuria are equally adapted in Indang, Cavite.
2. Yield parameters are significantly affected by fertilization scheme with the notable advantage of using organic fertilizers.
3. Yield is not significantly affected by the interaction of fertilization scheme and variety.
Conclusions
3. Break-even yields in all varieties are lowest in conventional production. thus, there is higher profitability in this fertilization scheme.
4. Return on investment or profit is highest under zero fertilization scheme (control) and conventional fertilization for Tiwala 6 and Manchuria and under zero fertilization schem (control) and organic fertilization scheme for Tiwala 8.
Recommendations
1. Farm or field trial to test adaptability of soybean varieties across sites in Upland Cavite 2. Reduce cost of production following the organic scheme by using farm-derived inputs and farm processed fertilizer materials instead of commercially available ones 3. Soil analysis prior to planting of soybean in any site/farm
