The experiment was conducted at the screen house of the Department of Biological Science Abubakar Tafawa Balewa University Yelwa Campus Bauchi State, Nigeria, located at 10ͦ 16’ 52’’ N 9ͦ 19’’ longitude and latitude. The objective of this research is to determine rice genotypes nutrient use efficiency under low NPK fertilizer treatments. The whole experiment was randomized using Microsoft excel in a completely randomized block design (CRBD) with four replications, the germinated seedlings of each cultivar from the petri-dish were planted into two each in plastic pots measuring 30cm with drainage holes at the bottom and the soil of 1.5kg was filled into the pot. For the NPK treatments, two levels of fertilizer adopted were 200kg/ha^-1 NPK, which was considered as full dose (FD), and the control, while the 100kg/ha^-1 NPK was considered as half dose (HD), and the other experiment tag CF, and without application of fertilizer. The whole experiment was given continuous water flooding throughout period. The experimental data collected of plant height, tillers, shoot mass, root mass, and grain yield on FARO 37, FARO 38, FARO 41, FARO 45, FARO 48, FARO 51, FARO 52, FARO 60, FARO 61, FARO 62, FARO 64, FARO 65, and FARO 66 were subjected to analysis of variance, from the results obtained, and the outcome showed was no significant difference between the treatments. This could suggest the rice cultivars resilience to NPK.
