1. Nutrient Management Studies in Bio-Fuel Cropping SystemsResearch was conducted to determine the effect of nutrient management practices on bio-fuel crop production, and to evaluate long term effects of bio-fuel crop production on selected chemical, physical and microbiologi cal properties. Experimental plots for research on bio-fuel crops production were established in 2008 at two sites in Missouri. The experimental design was an 8x3 factorial laid out in a sp lit plot design. The main plots were eight bio-fuel cropping systems including: 1) continuous... |
2. Design, Wrangling and Analysis of an On-farm Strip Trial. Iowa Soybean Association MethodologiesIowa Soybean Association (ISA) has conducted over 4,000 replicated on-farm trials over the past 15 years. During this time, we have developed our own methodologies and approaches to the data. In this talk we review step by step ISA approaches to a replicated strip trial involving 5 nitrogen rates including trial design, data wrangling, data analysis and machine learning approaches. The talk concludes with discussion on some difficulties in on-farm research with an appeal to the science community... S. Nelson |
