I wish to know if one can only use soil water potentials from a treatment to show root activity or there is need for an independent investigation to measure root growth & developments?
Water is main but not only parameter which determine Root activity. If you want know how water influence root activity then water potential is appropriate parameter.
Thanks Mr. Biraj. I know understand that i will have to do some data collect on root traits for refining my hypotheses. I am working in upland rice for my DOCT programme.
