Type: article
Abstract: This study investigated the impact of using nano urea along with conventional urea on brinjal farming in the Western Undulating Agro-climatic Zone of Odisha. The research was conducted at the Regional Research and Technology Transfer Station (OUAT) in Bhawanipatna, Kalahandi, Odisha, India during October, 2022-23 (rabi season). Results showed that application of 50% STD of nitrogen + nano-urea spray at 3-4 weeks after transplanting at the rate of 8 ml L-1 of water recorded highest leaf area index, SPAD, nutrient uptake and yield of brinjal followed by 75% STD of nitrogen + nano-urea spray at 3-4 weeks after transplanting at the rate of 6 ml L-1. Result clearly showed that in T9 where foliar application of nano urea with the reduced supplementation of inorganic nitrogen fertilizer @ 50% has been applied increased the fruit yield of brinjal to the tune of 27% over the soil test dose of NPK (STD) and achieved maximum B:C ratio of 1.55. Results also showed that there is no significant impact was observed in fruit quality parameters of brinjal and post-harvest soil properties due to nano urea application.
