After a fruitful take off of implementation during the first year, projects on soybean continue to reap promising results.
Based on recent research findings, on the on-farm field trials of projects in Bukidnon (Region 10) and Agusan del Sur and Surigao del Sur (Region 13) under the Soybean R&D Program were visited and evaluated.
These field trials were monitored and evaluated by the Crops Research Division (CRD) of the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD) together with the Institute of Planting Breeding – University of the Philippines Los Baños (IPB-UPLB) and the Department of Agriculture (DA) – Regional Field Office (RFO) 10 and 13.
The regions are among the cooperating regions of DA and IPB-UPLB in the Soybean R&D Program, “Improvement of Soybean (Glycine max (L.) Merr.) for Better Nutrition, Higher Income and Enhanced Soil Health.”
The said program is part of the Industry Strategic S&T Program (ISP) for soybean. It aims to increase farmers’ income by integrating soybean in different cropping systems, enhance the sustainability of the informal soybean seed sector, and develop soybean varieties with enhanced functional properties.
Soybean Field Trials in Northern Mindanao
The team assessed the different on-farm trials in Region 10, specifically in Simulao and Libona, Bukidnon. The top performing soybean varieties in each experimental site were recorded based on set parameters.
According to Jemseal R. Napier of DA-NMACLRC, a soybean accession from the World Vegetable Center (previously known as the Asian Vegetable Research and Development Center) called SP 963-9 performed best in Libona; while ‘Manchuria’ topped the four trials in Sumilao. AGS 374, a soybean accession from Tiwala 8 x LXI8A (lipoxygenase null) selection, ranked second in all on-farm trials while Tiwala 6 ranked third.
In terms of pests and diseases, AGS 374 remained resistant to aphids and powdery mildew compared with SP series in on-farm trials in Sumilao.
Further research and evaluation of the said varieties aim to determine the soybean lines with desired traits and suitable to different growing areas.
On-Farm Research Trials in Caraga
Meanwhile, Tijani B. Auxtero of the DA-RFO 13 Research and Experiment Station/RES reported the progress and accomplishments of the project in Caraga.
The fourth cropping cycle for corn-based and rice-based cropping systems have started and harvesting is expected in December 2019. Soybean plants, on the other hand, are already on their third harvesting.
Results of the initial soil sampling and characterization in both corn and rice areas will determine the effect of soybean on soil health after a series of trials when integrated in the cropping system.
Evaluation of soybean lines was done on-station and on-farm. Initial findings show that the top five soybean varieties are SP 963-5, SP 963-7, SP 963-1, SP 963-6, and SP 963-2. All of these varieties exhibited good crop stand and high number of pods.
Furthermore, a meeting with farmer-cooperators was held to gather information on farmers’ practices specifically on harvesting, drying, packaging, and storage of soybean seeds.
The Soybean R&D Program, under the leadership of Mr. Elmer E. Enicola of IPB-UPLB, is a three-year endeavor to help the local soybean industry (PPCI).
