Experts please help me to analysis the data I collected from on farm trials. The trial has been laid out in 04 different farms/location as blocks. The 15 cultivars/treatments appear only once in a block. The cultivars in each block differs (block size) and some treatments appears together in some blocks. The data I collected is area under the disease progress curve for a disease for two disease seasons (season 1 and season 2). My objectives are 1) To see whether the cultivar response to the disease is significant 2) cultivar * location interaction 3) cultivar * season interaction 4) cultivar*location*seasons interaction. How can I analyze the data? Which program I can you and what the sas codes?
This is not a contract work site. If you have specific questions, post some test data in the form of a datastep, then show what the output should look like. Explain the logic in between. Use clear concise language, thread topic included.
An analysis plan should have been developed before data collection. Otherwise you might not end up with the data collection needed to answer the research questions.
Thank you for your responses. Actually the experiment was laid out for some other purpose mainly for yield data collection. During the experimentation we happened to collect disease severity data, I am trying to analyze them. As it is a non-replicated on farm trial data, I can't use ANOVA or other methods which need replicates.
