## ANSWER

## THE MINISTER OF STATE IN THE MINISTRY OF CHEMICALS AND FERTILIZERS (SMT. ANUPRIYA PATEL)

- (a) The consumption of Nano Urea and Nano DAP is increasing over the years in the State of Karnataka.  Among tobacco and ginger cultivators, particularly in Mysuru and Kodagu districts, there is increased trend in the adoption of nano urea and nano DAP. A total  of  1,70,827  bottles  of  Nano  urea  and  62,360  bottles  of  Nano  DAP  were  sold  in Mysuru and a total of 51,022 bottles of Nano urea and 35,170 bottles of Nano DAP were sold in Kodagu districts from 2022-23 to 2024-25. District wise consumption of Nano Urea and Nano DAP is placed at Annexure- I.
- (b) The sales and usage of Nano Urea and Nano DAP along with the comparative figures for conventional Urea and DAP in Mysuru and Kodagu district for the period from 202223 to 2024-25 is placed at Annexure-II.
- (c) In order to assess the impact of Nano fertilizers, an MoU has been signed between National Productivity Council (NPC) of India and Department of Fertilizers on 5th March, 2024 to undertake the study of Nano Urea on "Evaluating Efficacy, Utility and Impact of Nano Urea in comparison to Conventional Urea'. A Phase-II study by NPC has also been signed on 14.11.2025 for evaluating the extent of replacement of Conventional Urea by Nano Urea. As per the NPC assessment based on the farmers feedback, crop yield in the  tobacoo  (Gujarat),  Coriander  (Madhya  Pradesh),  Chilli  (Andhra  Pradesh,  Gujarat, Uttar Pradesh), Garlic (Madhya Pradesh) improved as a result of mixed use of Nano Urea and Conventional Urea.

Additionally, an MoU has been signed with ICAR on 03.11.2025 for undertaking a Network Project on the evaluation of nano urea on crop productivity and nitrogen use efficiency in diverse Agro-Ecological zones of India, jointly funded by fertilizer PSUs/cooperatives for implementing across multiple collaborating agricultural institutions for a period of five years.

Furthermore,  ICAR  has  also  initiated  a  2024-26  project  funded  by  the  Indian Council for Fertilizers and Fertilizer Technology Research (ICFFTR), with a total outlay of ₹160 lakh, to evaluate the impact of Nano Fertilizers on crop growth, soil health, and nutrient uptake across various agro-ecological zones. This project, too, involves several collaborating agricultural institutions.

- (d) The Government of Karnataka informed that Nano Urea and Nano DAP are being promoted as alternatives to conventional Urea and DAP in the concerned districts through the Department of Agriculture, in coordination with Krishi Vigyan Kendras (KVKs) and nano fertilizer manufacturers. Extensive awareness programmes have been conducted to educate farmers and public representatives on the benefits of nano fertilizers and the judicious  use  of  conventional  fertilizers  through  handouts,  posters,  mobile  vans,  and advertisements  in  print  and  electronic  media.  Field  demonstrations,  including  dronebased applications under the Food and Nutrition Security programme, have also been organized in farmers' fields and at KVKs to encourage adoption.

Nano fertilizer manufacturers informed that various awareness campaigns and demonstration programs have been conducted to educate farmers across Karnataka, including  the  Mysuru  and  Kodagu  districts.  The  promotional  activities  have  been conducted by Nano fertilizer manufacturers (during the period FY 2023-24 to FY 2025-26 (till January 2026)) are as follows:-

| S.no   | Promotional Activities                                          |   Mysuru |   Kodagu |

| (ix)   | Distribution of technical literature in Kannada | 60,000 | 20,000 |

Nano fertilizer manufacturers have also informed that the mass media platforms utilized for the campaign include cable TV networks, TV news channels, digital media platforms, and All India Radio.

(e)    Government of India, in coordination with State Governments, is adopting a cropand region-specific approach for the promotion of nano-fertilizers with the objective of improving adoption, enhancing nutrient use efficiency and reducing long-term dependence on fertilizer subsidies in high-input cropping regions. Promotion strategies include targeted demonstrations, farmer awareness programmes and integration of nanofertilizers  with  existing  extension  mechanisms,  particularly  in  regions  with  intensive fertilizer usage and high subsidy outgo.

Further, the Government of Gujarat has taken a proactive initiative by providing 50%  subsidy  for  the  adoption  of  nano  urea  in  the  State.  Additionally,  large-scale awareness and outreach activities were conducted under the Viksit Bharat Yatra during the Kharif 2025 season, through village-level programmes to disseminate information on the benefits and application of nano urea to farmers. These initiatives reflect a focused effort  to  encourage  responsible  adoption  of  nano-fertilizers  through  region-specific support mechanisms.
