3=2+1 means N.P.K. =Biological & Organic (natural source) + Synthetic
In different research projects(Jaipal et.al. July 2011) it has proved that crop productivity is increasing by balanced use of Biological, Organic and Synthetic. Our research project at BCKV and IIT on paddy also proved the truth.
