Abstract: Foxtail millet (Setaria italica L.) is an important crop in arid and semiarid regions of the world because of its drought tolerance. Nitrogen is one of the most limiting nutrients in crop production due to low availability and loss. We hypothesize that there are differences in physiological and yield traits among foxtail millet genotypes in response to N. The objectives of this study were to determine the responses of foxtail millet genotypes to N fertilizer and the relationship between their yield, yield components and quality traits. A field experiment was carried out during kharif, 2016 and 2017 on red sandy clay loam soils of Agriculture College, UAHS, Shivamogga. The experiment was laid out in randomized complete block design with factorial concept and replicated thrice. The treatments consisted of three foxtail millet genotypes viz., Local, HMT-1 and SIA 2644 and five nitrogen levels viz., 0%, 50% and 100%, 125% and 150% of RDN ha-1. The foxtail millet genotypes were evaluated for yiels and yield parameters viz., number of productive tillers, panicle length, panicle weight, grain yield and straw yield and quality parameters protein percent, and fibre percent. Nitrogen levels have significant effect on both yield components and quality parameters of foxtail millet genotypes. Among different nitrogen levels application of 125% N ha-1 recorded significantly higher yield components viz., number of productive tillers hill-1 (13.65) at harvest, panicle length (15.72 cm), panicle weight (7.24 g) and test weight (3.52 g) as well as grain yield (2189 kg ha-1) and straw yield (4643 kg ha-1) with respect to quality parameters, 125% N ha-1 recorded significantly higher protein percent (11.55) whereas 100% N ha-1 recorded significantly higher fiber percent (6.06) compared to other Nitrogen levels. Among genotypes, SIA 2644 resulted significantly higher yield parameters like number of productive tillers hill-1 (10.08) at harvest, panicle length (14.28 cm), panicle weight (6.16 g), and test weight (3.28 g) grain yield (2246 kg ha-1) and straw yield (4823 kg ha-1) followed by HMT-1 and Local. With respect to quality parameters, SIA 2644 recorded significantly higher protein percent (8.72) and fiber percent (5.32) as compared to other genotypes.
