Technology assessment, transfer of tuber crops technologies and generation of socio-economic and impact information on tuber crops are done by this section. Various means and modes of technology transfer are 1.On farm trials, 2.front Line demonstrations, Field days, Farmers Seminar, Extension Literature etc. Visitor service is another important work of this section. Development and maintenance of the website of the institute, online agro advisory, cyber extension, bioinformatics, development of statistical applications for tuber crops research, market studies and other economic applications, studies on consumer preferences etc. are some of the other activities going on in the section.

FLDs conducted in Salem district revealed that the yield of Sree Athulya was 9.42% higher than the local varieties with a B:C ratio of 2.74 and in Namakkal district the yield of Sree Athulya was 11.91% higher than the local varieties with a B:C ratio of 2.07. OFTs on high yielding CMD resistant variety Sree Kaveri in Salem and Namakkal districts revealed that the yield was 9.80% higher (with a B:C ratio of 2.78) under irrigated conditions and 7.97% higher (with a B:C ratio of 2.60) under rainfed conditions than the local varieties. FLDs on SSNM in Chinese potato conducted in Tenkasi district revealed that the yield of SSNM treated plot of Sree Dhara gave 12.15% higher yield than the local varieties with a B:C ratio of 2.74 and in Tirunelveli district the yield of treated plot of Sree Dhara was 9.78% higher than the local varieties with a B:C ratio of 2.81.

Three FLDs conducted in Attapadi taluk showed that Bhu Kanti produced the highest tuber yield (20.27 t ha^-1) than Bhu Sona and Bhu Ja. Acceptability of millet porridge by students indicated that malted ragi rated significantly higher than the folate enriched ragi for its appearance (t=3.38; p<0.05), taste (t=2.24; p<0.05) and mouth feel (t=3.202; p<0.05).

Women empowerment in sweet potato production in Belgaum district involving 60 men and 60 women farmers revealed that the overall empowerment index in sweet potato was 0.82 for men and 0.58 for women.

Impact assessment on improved varieties of cassava conducted among 300 farmers in Tamil Nadu revealed that 47.31% of the farmers adopted improved varieties of cassava which gave an additional yield and income of 13% and 17%, respectively.

An interactive cassava genomic variant database was developed, including SNP and InDel data for Sree Kaveri and 9S-127 varieties. AgriAnalytics@R Ver. 3.10 developed offer modules for statistical analysis and data visualization for agricultural research. The R package baseq, submitted to CRAN, provides function to process biological data.

Planting material of 10,000 kg of greater yam, 1000 kg of elephant foot yam, 400 kg of taro, 100 kg of yam bean, 10,00,000 cuttings of sweet potato and 6000 stems of cassava, four types of small tools (each 300 nos.) were distributed to 310 tribal farmers from three districts of Odisha and one district of Andhra Pradesh under ICAR-CTCRI-TSP programme. Ten on-farm trainings were organized on crop diversification with tuber crops and value addition. Under SCSP programme, 120 field demonstrations on improved varieties of cassava and elephant foot yam was carried out in Parakkode block, Pathanamthitta district of Kerala and Cuddalore and Karur districts of Tamil Nadu. Planting materials of 25,000 stems of cassava such as Sree Kaveri, Sree Athulya inputs, farm tools and implements were distributed to 140 beneficiary farmers. Seventeen outreach programs were conducted for the benefit of 717 farmers and other stakeholders.

Under NEH programme, rearing Eri silk worms in Assam by feeding with the leaves of cassava variety Sree Reksha was profitable, with 6000 kg of cassava leaves per acre annually supporting 400 larvae, yielding a net profit of ₹ 60,000. A total of 43 demonstrations on biofortified sweet potato varieties of Bhu Sona and Bhu Krishna conducted in Meghalaya and Tripura States showed that Bhu Krishna produced higher tuber yield (10.94 t ha^-1) compared to Bhu Sona (8.78 t ha^-1). Five nutriseed villages of biofortified sweet potato varieties of Bhu Sona and Bhu Krishna were established in Tripura, Meghalaya and Assam, with 10 farmers enrolled in the DSM seed scheme for promoting sustainable farming practices and economic growth.

Six technologies were licensed and two MoUs for contract research and one MoU for consultancy service were signed. A patent application for an apparatus for peeling agricultural products was filed. Eight technologies were certified by ICAR. The technology on e-Crop based smart fertigation system was selected as one of the five best technologies in horticulture sector.

ICAR-CTCRI is an approved Research Centre for undertaking Ph.D. programmes. During the period, the Institute has offered internship training to B.Sc./B.Tech students, project work of M.Sc. students, imparted technical guidance to Ph.D. scholars, totaling to 198.

A total of 5916 farmers, 105 students and 703 officials from different parts of the country were imparted training by ICAR-CTCRI. The institute participated in 28 exhibitions and carried out 717 FLDs/OFTs.
