abstract
A field experiment was conducted to study the effect of nano urea and nano DAP on growth and yield of transplanted rice at Agricultural Research Station, Dhadesugur, UAS, Raichur during kharif, 2023 in vertisol. The experiment was laid out in a randomized complete block design with three replications and eight treatments comprising of different doses of nano urea and nano DAP along with soil application of conventional fertilizers. The results revealed that, treatment receiving 50% Rec. N with soil application + 50% Rec. N through nano urea with two applications (at tillering and panicle initiation stage) + Rec. P & K with soil application recorded significantly higher growth and yield attributes resulted in higher grain yield (5578kg ha^-1), gross returns (Rs. 1,84,933 ha^-1), net returns (Rs. 122,725ha^-1) and BC ratio (2.97). The experimental results concluded that, treatment receiving 50% Rec. N with soil application + 50% Rec. N through nano urea with two applications (at tillering and panicle initiation stage) + Rec. P & K with soil application was best to get higher grain yield.
