The low return from soybean planting in recent years has made farmers less interested in soybean. As a result, soybean acreage went down and soybean production fell from the record 17.40 million tons in 2004 to 15 million tons in 2006. As the downward trend continues through 2007, the gap of demand for soybeans is widening.

Soybean will be planted into wheat stubble immediately after wheat harvest with a five-38-cm-row plot planter at 592,800 seed ha-1 seeding rate to obtain 444,600 soybean plants ha-1 plant population. All seed will be treated with Optimize® liquid inoculant a day prior to planting at 82.8 ml 45.4 kg seed-1 and be allowed to dry.

Some risks to planting high population soybeans are disease, plant competition with each other, and spending too much on seed costs. There is a lot that goes into finding the right soybean population. Materials and Methods. The two soybean varieties that were used were Pioneer® P18T85R and P27T03R. They were planted no-till on May 5th and 21st.

Forty (40) to 60 kg of soybean seeds are needed per hectare. Use seeds with high germination (80% or higher). Unlike palay, soybean seeds lose their viability in a short span of time. After 3 to 4 months in ordinary storage condition, germination will be less than 50 percent. Before planting, sun dry soybean seeds for about 2 hours.

By planting soybean at different elevations in the same latitude, any interactive effects between photoperiod and temperature on plant growth and development were minimized. Thus, the site effects on grain yield, symbiotic N2 fixation, and soil N uptake of soybean genotypes were assumed to be due to differences in temperature.

Mar 22, 2017 · The treatments will be arranged randomly in the 12 plots. All of the plots will be planted with the same planter at the recommended population setting for the selected cultivar. Hence, each plot will have approximately the same population density. The only difference between the plots will be the number of seed tubes that apply the seed into ...

Hand harvesting is required and a single F3 seed from each plant is placed in an envelope for planting the following generation (thus one planting envelope per population). For practicality, one head or one pod may be harvested from each plant in the field, but a single seed from each head or pod is put into the planting envelope at a later date.

Soybean Aphid Pest status: The soybean aphid, a pest native to Asia, was first found in 2000. It caused yield loss in 2001 and 2003. Type of damage: Aphids are sucking pests that remove plant sap. Soybean aphids can reproduce rapidly, resulting in hundreds of aphids per leaf; this population level appears to reduce pod number.
