Potato is one of the most important crops grown worldwide. Current research was performed to identify theinfluences of various types of nano-fertilizers, biofertilizer and bulk fertilizers on tuber yield and some other traits of theSprit potato variety. The trial was arranged in a randomized complete block design with three replicates with six nutritionaltreating; control, NPK in bulk form, MOG biofertilizer, nano-calcium, nano-zinc plus nano boron and complete nanofertilizerand various twelve traits of potato were measured. They were number of leaves (NL), number day to initiation oftuberization (DIT), days to row closure (DRC), days to flowering (DF), number of tubers per plant (NTP), number of stems(NS), tuber yield (TY), mean tuber diameter (MTD), mean tuber weight (MTW), tuber weight per plant (TWP), dry mattercontent (DM) and starch total (ST). The factor analysis indicated that the first two factors, accounted 92% of variabilityand revealed that MOG biofertilizer was related to days to row closure and mean tuber diameter, while NPK producedthe high numbers of stems. Also, no fertilizer usage (control) caused delay to initiation of tuberization, while completenano-fertilizer had the higher amounts of the other traits like tuber yield. For obtaining the more number of leaves perplant, using complete nano-fertilizer following to nano-zinc plus nano boron is advise while for more numbers of tubersper plant, application of all tested nano-fertilizers is useful. The nano-fertilizers have beneficial ability in comparison tobulk-form and biologic fertilizers, thus nano-fertilizers especially the complete nano-fertilizer should be used to minimizethe harmful influences of nutrient shortage and reaching targets of sustainable and low-input agricultural systems inproduction of potato under semi-arid environments.
