Abstract: The present experiment was conducted to study the “Effect of foliar spray of NPK complex on yield and nutrient uptake of rice cultivars” during kharif season, 2022 at the research farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, C.G. The experiment was laid out in Split plot design with three replication having nine main plot treatments i.e., rice cultivars viz fortified and improved-M1-MTU-1010, M2-Dubraj, M3-Zincorice, M4-Protozin; traditional cultivars viz M5-Devbhog, M6-Badshahbhog, M7-Vishnubhog and; hybrid cultivars viz M8-US-312 and M9-Arize-6444 and three subplot treatment of S1-absolute control, S2-100% RDF and S3-foliar spray of NPK complex 19:19:19 @ 1% after tillering and at panicle initiation. The results revealed that the grain and straw yield of all rice cultivars were numerically higher under 80% RDF + foliar spray of NPK complex 19:19:19 @ 1% than under 100% RDF but were statiscally at par. Whereas under absolute control was found significantly lowest than the other two treatments. MTU-1010 under 80% RDF + foliar spray of NPK complex 19:19:19 @ 1% exhibited significantly higher grain yield (54.29 q/ha) followed by Protozin (47.38 q/ha) whereas whereas the grain yield of Dubraj (42.62 q/ha) and Zincorice (43.59 q/ha) were statiscally at par. Devbhog (37.49 q/ha) showed maximum grain yield under S3 followed by Vishnubhog (26.58 q/ha) whereas Badshahbhog recorded minimum grain yield (25.19 q/ha) while between hybrid rice cultivars Arize-6444 (66.20 q/ha) exhibited significantly higher grain yield than US-312 (62.6 q/ha) under all three treatments. The nutrient uptake and efficiency followed the same trend of grain yield. Protozin (2.28) recorded highest B:C ratio followed by Dubraj (2.03), Zincorice (2.02), whereas MTU-1010 (1.64) recorded the lowest among fortified and improved varieties. Devbhog (2.1) gave maximum B:C ratio followed by Vishnubhog (1.57) and Badshahbhog (1.44) among traditional cultivars; whereas Arize 6444 (2.81) had maximum B:C ratio among all cultivars.
