Abstract:
Nanoparticles (NPs) are used as nano-fertilizers, and have significant potential to increase the agricultural production. Sugarcane budnodes were primed with various doses of Fe NPs and Zn NPs each @ 25, 50, 75 and 100 mg L-1 along with hydropriming and control treatment. The experiment was conducted at College of Agriculture, University of Sargodha, Sargodha, Pakistan during October 2016-17. Results of experiment showed that hydropriming significantly (P=0.05) improved the budnodes sprouting characteristics like, sprouting establishment, time to 50% emergence, seedling vigour index followed by Fe NPs @ 50 mg L-1 and Zn NPs @ 75 mg L-1. Moreover, significantly (P=0.05) longer shoot and root length, shoot and root fresh weight and shoot and root dry weight were recorded in hydropriming followed by Fe NPs @ 50 mg L-1 and Zn NPs @ 75 mg L-1. Photosynthesis rate, chlorophyll and carotenoid contents were higher in sugarcane when sown after hydropriming followed by Fe NPs @ 50 mg L-1 and Zn NPs @ 75 mg L-1. However, higher Fe and Zn content in shoot of sugarcane were noted when budnodes were sown after priming with Fe NPs @ 75 mg L-1 and Zn NPs @ 50 mg L-1. From the results of our study, it is concluded that pre-plant treatment of sugarcane budchips with nanoparticles Fe NPs @ 50 mg L-1 and Zn NPs @ 75 mg L-1 increased their seedling establishment, growth and physiological traits. Therefore, NPs enhanced the performance of budnodes sprouting at initial stages that can improve productivity of sugarcane.
