I want to apply ZnO nanoparticles for mitigation of salinity in rice but confused about proper doses. So please suggest me the optimum doses of ZnO as foliar spray. Thank you.
This is not a question to be straight away followed and there cant be any universal recomemndation , unless epxerimented. Please have a look at these PDFs....these will give you some valid clues....
The extent of deficiency and toxicity of the trace elements is very close, so the fertile state of the soil must be determined and the concentration of addition must be estimated.
Foliar exposure of zinc oxide nanoparticles improved the growth of wheat (Triticum aestivum L.) and decreased cadmium concentration in grains under simultaneous Cd and water deficient stress https://www.sciencedirect.com/science/article/pii/S0147651320314640
