Impact of Front Line Demonstrations on Yield Enhancement of Ginger (var. Nadia) Raised Single Node Seedlings through Pro Tray Technology in Tribal Area of Alluri Sitaramraju District of Andhra Pradesh, India

To overcome the problems of high seed usage due to the high cost of seed material and rhizome rot disease in ginger in tribal agency areas of ASR district. Hence, the ICAR-ANGRAU, Krishi Vigyan Kendra, Kondempudi conducted Front Line Demonstrations (FLD) in five selected villages, namely Paderu, Peddabayalu, Hukumpeta, Dumbriguda, and Araku mandals of Alluri Sitaramraju district (ASR) of Andhra Pradesh, for three years (2019–20, 2020–21, and 2021-22). The purpose of the FLD was to showcase the superior performance of single node raised seedlings of the ginger variety Nadia raised through portray technology compared to the normal farmer practice variety Nadia. The single-node ginger (Var.Nadia) seedlings cultivated using technological demonstration of yield and economic analysis in contrast to farmers' practices 50 farmers participated actively in the FLD, which covered 20.5 acres. In terms of production, pooled fresh rhizome yields of 139.57 and 120.02 q/ha, respectively, showed that single-node grown seedlings of ginger var. Nadia raised by modern technology were superior over farmer practice. Single-node ginger (var. Nadia) seedlings grown by this technique exhibited an upsurge in fresh rhizome output from 10.28 to 20.39 percent over the course of the demonstration years. Average cost-benefit ratios for the three years for demonstration plots and farmer practice were 1:3.18, 1:3.26, and 1:3.61, and 1:2.09, 1:2.08, and 1:2.01, respectively. The extension gap of three years (2019–20, 2020–21, and 2021–22) was 27.71, 16.1, and 14.84 q/ha in demonstration plots, respectively. Results on the Technology Index ranged between 12.07 to 6.62% and 20.78 to 5.17% for single-node ginger (var.Nadia) seedlings raised through pro tray technology and farmers’ practices, respectively. All three years of study revealed that for single-node ginger (var.Nadia) seedlings raised through portray technology, there is much significance and scope for up scaling the demonstrated technology in tribal agency areas of Alluri Sitaramraj district, Andhra Pradesh.
