The field demonstrations were carried out based on the technological interventions on the tomato crop in three tribal villages namely Kota Kwanu, Majhgaon Kwanu and Malot Kwanu in Chakrata block of Dehradun district of Uttarakhand in 30 ha area (10 ha in each village) during March to August, 2016 and 2017 under centrally sponsored project i.e. Tribal Sub Plan (TSP). The average yield was 275.72 Q/ha in Kota Kwanu, 280.75 Q/ha in Majhgaon Kwanu and 272.23 Q/ha in Malot Kwanu during 2016. However, net income was maximum i.e. Rs. 3,65,500/ha in Majhgaon Kwanu while it was Rs. 3,55,440/ha and 3,48,460/ha in Kota Kwanu and Malot Kwanu, respectively in farmers practice whereas, during 2017 the average yield was higher in Kota Kwanu which was 227.27 Q/ha followed by 213.45 and 211.77 Q/ha in Majhgaon Kwanu and Malot Kwanu respectively. The net income was also highest in Kota Kwanu i.e. Rs. 3,68,175/ha while it was Rs. 3,33,625/ha in Majhgaon Kwanu and Rs. 3,29,425/ha in Malot Kwanu during 2017. The impact of field demonstrations revealed that yield and income was doubled in the demonstrated tomato crop as compared to farmers practice. The average yield was maximum in Majhgaon Kwanu i.e. 489.36 Q/ha while it was 471.63 and 460.72 Q/ha in Kota Kwanu and Malot Kwanu, respectively during 2016. Similarly, the net income was also highest in Majhgaon Kwanu which was Rs. 7,40,720/ha followed by Rs. 7,05,260 and Rs. 6,83,440/ha in Kota Kwanu and Malot Kwanu, respectively during 2016. During 2017, the average yield was low but net income was similar of 2016 as the sale price of tomato in 2017 was higher to 2016.
