The experiment was conducted at Agricultural Research Station, Kota during 2018-19 to evaluate potato cultivars viz. AICRP -P-39, KufriBahar and KufriPukhraj at four N levels (0, 80, 160 and 240 kg N/ ha), to find out the N requirement and agronomic use efficiency of N. Results revealed that KufriPukhraj recorded maximum yield, agronomic efficiency and net return at 160kg/ha of nitrogen followed by proved to possess high tolerance to N stress and was the most nitrogen efficient variety followed by AICRP -P-39. This variety can be useful for resource poor farmers as this produces higher yield compared to other released varieties even at lower doses of N. | Effect of different dose of nitrogen on various varieties of potato in south eastern Rajasthan
