Complete Details of Technology:	:
The turmeric is a long duration rhizomatous crop, with a crop period of 6-8 months, removes N up to a level of 250-350 kg/ha from soil based on their yield levels. Supply of N during the critical growth phases (tillering and maximum vegetative phase, rhizome formation and bulking) spread over 4-5 months is required for its proper growth and development. So, to enhance the use efficiency of soil applied N and to minimise the loss of applied urea, �Nano Urea� N formulation can be used to fulfil the plant N requirement. Nano formulation of Urea is supposed to increase the N availability to crop by more than 80% resulting in higher Nutrient Use efficiency so as to reduce the dosage of soil application of conventional urea.
Brief Description of Technology Including Salient Features:
Foliar application of nano urea @ 0.2% for turmeric (two sprays at the active growth period of the crops, 90 & 120 DAP) along with 50% of the RDF N as soil application is recommended for higher N use efficiency and rhizome yield.
Benefits/Utility	:
The turmeric dry rhizome yield in 50% soil N + 0.2% nano urea was on par with 100% soil N and application giving an additional advantage of reduction of N application rate by 50% through foliar supplementation of @ 0.2% nano urea as a strategy for higher use efficiency of applied N fertilizers. This has resulted in more efficient use of N by the crop giving equivalent yield as that of recommended dose of fertilizers.The nutrient uptake of major nutrients also found to be significantly higher in 50% N + 0.2% nano urea as the rhizome yield was higher.
How To Use	:
Mix 2.0 ml of Nano urea (4%) in one liter of water and spray on turmeric crop leaves at active growth stages(at 90 & 120 DAP).
Impact, If Adopted	:
The rhizome yield is significantly higher under 0.2% nano urea + 50% soil N, 12.5% higher than that of 100% soil N application. The reduction of N application rate by 50% could be achieved through foliar supplementation of @ 0.2% nano urea.
Social Impact	:
The net profit over the cost of applied N (both as soil and nano foliar) was very high in turmeric and amounted to Rs. 4.0 lakhs per ha in treatment with 0.2% nano urea supplementation combined with 50% soil N application.
