Effect of foliar sprays of nano-urea on growth, yield and quality of rabi maize (Zea mays L.)

The present investigation on “Effect of foliar spray of Nano urea on growth, yield and quality of rabi maize (Zea mays L.) was conducted during rabi 2022-2023 at Agronomy farm, College of Agriculture, Pune. In this regard, the present investigation was set out in randomized block design with thirteen treatments and three replications. The study revealed that adoption of 75% N through conventional urea + 25% N through two foliar spray of IFFCO Nano urea, twice at 30 and 45 DAS was superior in influencing morphology, yield attributes and yield of rabi maize. However, since adoption of 75% N through conventional urea + Two foliar spray of COAP Nano urea @ 12 ml/L twice at 30 and 45 DAS was significantly at par with 75% N through urea + Two foliar sprays of 2% urea this might be a most appropriate managerial alternative to achieve sustainability.
