An essential cultural technique for ensuring correct development and maximizing output is administering fertilizer sources for the crops. The experiment was carried out from February 2022 to May 2022 at Khadbari-3, Maruwa, Sankhuwasabha, to determine the efficacy of various dosages of NPK on the growth performance of the rice bean variety (Sunehri). The trial used a Randomized Complete Block Design (RCBD) with seven treatments replicated three times. The treatments were listed and named as T1 (0:0:0 kg NPK/ha); T2 (20:30:10 kg NPK/ha) (Recommended dose); T3 (10:20:15 kg NPK/ha); T4 (40:80:40 kg NPK/ha); T5 (20:20:20 kg NPK/ha); T6 (80:100:60 kg NPK/ha); and T7 (20:0:30 kg NPK/ha), respectively. The experimental results revealed that the highest yield/plant (39g) was obtained from the plot treated with T4 (40:80:40 kg NPK/ha), followed by 24.93 g and 24.13 g from the plot receiving T2 (20:30:10 kg NPK/ha) and T6 (80:100:60 kg NPK/ha), respectively. The lowest yield of 14.07 g was obtained from the control plot, followed by 15.27 g and 21.20 g from the plot receiving T7 (20:0:30 kg NPK/ha) and T3 (10:20:15 kg NPK/ha), respectively. Vegetative parameters such as plant height, branch numbers, and leaves numbers were recorded as a maximum of 19.72 cm, 6.88, and 18.97 in plots treated with T5 (20:20:20 kg NPK/ha), T7 (20:0:30 kg NPK/ha), and T1 (0:0:0 kg NPK/ha), consecutively, and corresponding minimum values were found 18.12 cm, 5.36 and 15.63 in T3 (10:20:15 kg NPK/ha), T1 (0:0:0 kg NPK/ha), and T7 (20:0:30 kg NPK/ha), respectively. Conclusively, the study's findings suggest that the rice bean crop responds to fertilizers and applying T4 (40:80:40 kg NPK/ha) enhances crop production considerably.
