I attached all the details in a document so you can watch by yourself.
There are no significant differences between treatments, but still treatments with PR added to the pot in the substrate making show slightly more chlorophyll content than treatments that had PR added in the biofertilizer making process, which should had been solubilized by microorganisms.
Hi Vicente,
It seems that a fertility factor other than the ‘available phosphorous’ is responsible for your results.
It may be useful to know the following (to derive at a possible explanation for the results):
(1) Did you record the parameters such as: plant dry weight, leaf dry weight, leaf area? How they respond to the treatments.
(2) What is the exact dry weight of Bakashi compost added at each level (at 10%, 15% 30%) and what is the weight of soil in each treatment?
If you know the values for this second question, you can quantify the absolute quantities of nutrients added in each treatment (ammonium –N, Nitrate-N, and total N, available P, K and others), and then may be able to examine possible other nutritional factors that may be responsible for the results.
Also, I am curious to know: what is the unit for ‘chlorophyll content’?
Furthermore, it may be more informative to analyze the results in a ‘factorial structure’:
Factor 1 (Level of Bakashi compost, 10%, 15%, 30%)
Factor 2 (method of phosphorus supply, BRE, BSR, BRM)
You have a two factor experiment (you need to leave out the B0 treatment out of this factorial analysis). Then you may be able to compare the results to examine the effect of the ‘level of compost’ and the effect of the ‘method of phosphorus supply’, independently and you may be able to know if there is an ‘interaction’ between the two factors.
I hope the answer to your original question may be easy to derive by examining answers to the questions I noted here.
