Database Research Summaries2018 Yield and Economic Evaluation of Soybean Biotechnology Varieties and Their Response to Selenium
Research Focus
The focus of this project is to develop soybean production management guidelines for western ND that increase yield and net profit of soybean producers.
Objectives
- Determine the most profitable soybean biotechnology varieties for western ND.
- Find out the effect of foliar application of selenium on physiology (NDVI), growth (plant height, biomass), yield, and quality of soybean biotechnology varieties.
Results
- Preliminary results showed that there was no effect of selenium on soybean yield and yield component. Selenium may need to be applied early in the morning when the ambient condition is not too hot and dry.
- There was no difference among the biotechnology varieties for growth and yield. Averaged across biotechnology varieties treated with deionized water and harvested from 9 sq. ft., the above ground biomass yield was 2945 lb/a, pod number was 16 per plant, grain number was 39 per plant, and grain yield was 28.9 bu/a.
- This study showed that RR1 varieties might perform similarly to other biotechnology varieties, under no-till dry land condition of western ND.
Importance
- This research will provide information to soybean producers on the potential advantage of RR1 soybeans over other two varieties in terms of yield and net profit return under no-till dry land condition of western ND.
- Also, this research determines whether the foliar application of selenium improves drought tolerance of soybean, which, if positive, will be effective in increasing soybean yield and the profit of entire ND dry land soybean growers.
