1) In field condition, for example, 65 seeds/plot were sown but in some plots 5 failed to germinate and in some 8 failed to germinate and so on....
So, how can the yield among different plots be compared?
Dear Rahul,
You may first work out the yield of genotypes per plant (instead of per plot) and then compare the corn genotypes on the basis of their yield per plant.
Yield per plant = Total yield recorded in a plot/ Number of corn plants in the plot
Also, when you have yield/plant, by considering normal density in the field, you can estimate yield/m2.
Randomized block design (RBD) can be used for statistical analysis in field condition.
Dr. Dilip, Thank you for the response. I was also thinking to go in same way but was not sure if I am right or wrong. I will go in same way now.
Dr. Suresh, I agree with Manoj sir about statistical analysis using RBD.
Manoj sir, Thanks for the attachment.
Dr. Saeid, my advisor also suggested the same way you did. Thank you for response.
You need to do ANCOVA analysis to be precise in your statistical interpretation. ANCOVA means Analysis of Covariance. You have to count the number of plants in each plot at the time of harvest and use number of plants as covariate for ANCOVA analysis. Statistical software package like MSTAT-B has the provision of ANCOVA analysis.
