Differential Response of Trifloxystrobin in Combination with Tebuconazole on Growth, Nutrient Uptake and Yield of Rice (Oryza Sativa L.)

The present investigation was carried out at Tamil Nadu Agricultural University to evaluate the influence of trifloxystrobin in combination with tebuconazole (Nativo) on the nutrient uptake, yield attributes and yield of rice. Foliar spray of Nativo was taken up at 50–55 days after sowing (DAS) and 70–75 DAS and observations were recorded at panicle initiation (60–65 DAS), flowering (80–85 DAS) and maturity (100–105 DAS) stages. The result indicated that Nativo significantly improved the root length, total dry matter production (TDMP) and nutrient uptake, but inhibited the shoot length. Among the different concentrations, Nativo @ 400 g ha⁻¹ performed better by increasing the fertility co-efficient, 1000 grain weight, panicle length and the grain yield in rice.

Different doses of Nativo were given as foliar spray at 50–55 DAS and 70–75 DAS in rice.

Among the concentrations applied, Nativo @ 400 g ha⁻¹ exhibited higher root length, dry matter production, nutrient uptake and thereby, grain yield.
