Abstract

The study was conducted under All India Coordinated Research project on potato at Research cum Instructional farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) during Rabi season 2021-22, in split plot design with three replications, for this research the experimental material consisting of twenty potato genotypes including two check variety Kufri Khyati and Kufri Chipsona-1.With three Nitrogen levels (0, 180 and 250 kg N/ ha), to find out the N requirement and Nitrogen use efficiency of Potato genotypes. The results of the present experiment revealed that all the genotypes are showing genotypic variability for NUE, there is sufficient variation for NUE. The genotypes used in the experiment show response to nitrogen and performing different the same genotype in three different nitrogen levels, among the twenty genotypes P-73 recorded maximum Nitrogen Use efficiency at all the levels of nitrogen followed by Kufri Mohan and Kufri Lalima. Genotype P-73 proved to possess high tolerance to N stress and was the most nitrogen-efficient variety followed by Kufri Mohan and Kufri Neelkanth. This experiment can be concluded that, the variety responded the same at 180 and 250 Kg Nitrogen can be recommended to apply only 180 kg of Nitrogen, the knowledge of NUE can save the money and land of farmers by minimal use of Nitrogen.
