Abstract

An experiment was conducted at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, India during Kharif season 2022 and 2023 to find out the effect of planting geometry and inorganic fertilizers with nano urea on growth indices of rice crop. All the growth indices parameters viz. Crop growth rate (g m-2 day-1) Relative growth rate (g g-1 day-1x 10-3), Net Assimilation rate (g m-2 day-1) and yield were significantly higher with the treatment P1 (20 cm × 10 cm) and F2 [100% RDF + foliar spray of nano urea @ 3000 ml ha-1(Tillering and Panicle initiation stage)] at par with treatment combination P1 (20 cm × 10 cm) and F3 [75% RDF + foliar spray of nano urea @ 3000 ml ha-1(Tillering and Panicle initiation stage)] and significantly higher than the other treatments. It can be concluded that treatment C1 (20 cm × 10 cm) with the application of F2 [100% RDF + foliar spray of nano urea @ 3000 ml ha-1 (Tillering and Panicle initiation stage)] proved better during both the year for all growth indices to achieve higher yield and remuneration of rice crop.
