Hey JackBean, thanks for your reply my friend..
As you can see, it’s an old one (1951) that’s why it was difficult to find it online, so I thought about post a request here hoping that someone can help me with it..
I’m doing a research regarding rooting response in mung bean as influenced by nitrogen and phosphorus.. I found the title above in the references of a paper, and when I googled for it I found it also in references of other papers just like that .. So, I posted it here hoping someone here can help me find it..
