Groundnut is a prominent oilseed crop in India but its productivity is far below the potential yield because of lack of knowledge along with adoption of enhanced varieties and technologies. The technology gap is a main issue in the production of groundnut in North Eastern zone of Tamil Nadu State in which Cuddalore district falls. A scientific and systematic effort was made to study the impact on yield by assessing the technological gap present in several components of the groundnut cultivation through cluster frontline demonstrations with scientific technologies.
Cluster frontline demonstrations were implemented in groundnut to improve the production potential of improved varieties and new technologies through Krishi Vigyan Kendra. The study with one of its objectives to assess yield and technology gap in groundnut was conducted with 175 demonstrations during the period from 2020-21 to 2022-23 covering seven blocks in an area of 70 hectares in the Cuddalore district following cluster random sampling method. Groundnut varieties VRI 8 and VRI 10 along with improved technologies were demonstrated in the farmer's field by providing necessary critical inputs along with seed drill sowing.
There resulted 53.34 per cent rise in yield as observed in demonstration plots over farmers’ practices in groundnut. The study revealed that in groundnut, the average extension gap of 13.95 q/ha, the average technology gap of 14.52 q/ha and the average technology index of demonstrations is 26.41 per cent. The higher average net returns (Rs. 149758/ha) were recorded in the demonstration plot (BCR 2.4) compared to the farmers’ plot. The sustainability yield index (SYI) and Sustainability Value Index (SVI) in demo plots are higher consistently than in farmers’ plots mainly due to the effect of cluster frontline demonstrations with the proper application of inputs/technologies viz., VRI 8 and VRI 10 varieties, treatment of seed by using bio-fertilizers, biocontrol agents, a test of soil based nutrient management, application of TNAU crop booster groundnut rich and gypsum application.
