Cases of large scale adoption

Case1: Demonstration of farmer’s participatory seed production of paddy variety TKM 13


In Cuddalore District, Paddy crop is cultivated in samba season in an area of 85000 acre. The crop is affected by various pest and diseases during Samba season. Existing varieties were highly susceptible and needs to be replaced with tolerant or resistant varieties. Hence, an FLD with TKM 13 variety was taken up and the susceptible variety BPT 5204 was used as a check. The trial was conducted at Azhichikudi and Manakudianiruppu villages of Bhivanagiri and Keerapalayam block. The crops performed well and provided good economic gain.


The results revealed that the paddy varieties TKM 13 (75.05q/ha) recorded higher yield than check (57.56 q /ha).  The net return was more in TKM 13, due to high market price (Rs 15.50/kg).

The pest and disease incidence in paddy variety TKM 13 was also less. The farmers did not take up any pesticide spray in TKM 13 variety. The crop yielded 7505 kg per hectare with less input on pest and disease management.

The net return received from the crop is Rs 57073 per hectare with the BC ratio of  2.02*

 d.Present status of the farmers in following the variety paddy TKM 13

  • Based on the performance of the paddy variety TKM 13 and its tolerance level to pest and disease incidence during Samba season the farmers were very much satisfied. Hence the programme is being taken up as a convergence mode and seeds will be produced in farmers’ participatory seed production programme.  

e. Socio economic impact

  • As the net return is more due to enhanced marketable price for the variety TKM 13, the farmers wish to go for cultivating the variety and the same is recommended for large scale adoption.
  • The farmers visualised the performance of the paddy variety TKM 13 throughout the season with their active participation.
  • The participation of the farmers in various domains shows positive impact on acceptance of the variety.
  • This year the variety paddy TKM 13 cover an area 10000 ha.

Case 2: Demonstration of farmer’s participatory seed production of Groundnut variety VRI 8

In Cuddalore District around 15000 ha is under Groundnut cultivation. Based on the interaction with the extension wing and farmers of the district it is realized that a bold seeded variety is needed for rabi season. Hence a variety released by the Tamil Nadu Agricultural University during the year 2016 named VRI 8 was taken up for demonstration during 2018-19. Ten demonstrations were conducted in an area of two hectares.


The variety performed well with its special characteristics of

  • Parentage : ALR 3/AK 303
  • Duration : 105 – 110 days
  • Season : Rainfed: April-May, June-July, October-November
  • Irrigated: December-January, February-March, April-May
  • Yield : Rainfed: 2130 kg/ha (22.0% over VRI 6)
  • Irrigated: 2700 kg/ha (26.6% over VRI 6) Highest yield obtained : 5170 kg/ha
  • Moderately resistant to late leaf spot and rust
  • Shelling outturn 70.0%
  • Oil content 49.0%
  • Medium bold kernels


The variety yielded as high as 4411 kg per hectare compared to the check variety VRI 2 (2860 kg per hectare). The net return from VRI 8 was Rs. 134488 per hectare with the BCR of 2.38 and the net return of VRI 2 was Rs. 45337 per hectare with the BCR of  1.41.

d.Present status of the farmers in adopting the variety VRI 8

  • Based on the performance of the groundnut variety VRI 8 and its performance the farmers are highly satisfied and requested for the seed material for the ensuing Rabi season. Hence training programme on seed production is proposed and seeds will be produced by adopting farmers’ participatory seed production programme.
  • This has led to vast spread of the variety in an area of 1000 hectare during 2018-19.

e.Socio economic impact

  • The farmers have realized that the variety is suitable for rabi season especially during North east monsoon.
  • Establishment of a network of small and medium seed growers in rainfed areas for the supply of quality seeds, and also to create awareness about new  varieties among the farmers
  • Farmer told that the number of pods per plant and yield was more in demonstration (i.e. 70 to 80 pods per plant) than the check due to management practices viz., seed treatment with bio control agents, gypsum application, balanced fertilizer application, herbicide application and management of pest and diseases guided by TNAU Scientists.
  • Farmer felt that groundnut rich application was easier than DAP application and has the advantage of increasing the pod setting. Drought tolerance was good
  • The successful performance of VRI 8  in terms of yield motivated other farmers in the village to adopt the variety
  • This has led to vast spread of the variety in an area of 1000 hectare during 2018-19.
