Abstract:
A field experiment was conducted on “Effect of nano urea application on growth and productivity of rice (Oryza sativa L.) under midland situation of Bastar region” at Research cum Instructional Farm S.G. College of Agriculture and Research Station, (IGKV) Jagdalpur, Chhattisgarh during Kharif season of 2021 in randomized block design (RBD) with ten treatments and three replications. The results showed that highest number of panicles m^-2, total number of grains panicle^-1, number of filled grains panicle^-1, test weight (g), grain (5195.83 kg ha^-1), straw yield (6250 kg ha^-1) and nutrient uptake was significantly highest under treatment T₅ 75% of RDN + Two foliar sprays of nano urea (AT and PI) which was at par with treatment T₄ 50% of RDN + Two foliar sprays of nano urea (AT and PI) and T₆ 100% of RDN + Two foliar sprays of nano urea (AT and PI). The lowest grain and straw yield (2558.33 and 3656.25 kg ha^-1) was recorded under control.
