     62  SOME PRELIMINARY RESULTS OF AN EIP-AGRI PROJECT ON SWEET POTATO CULTIVATION  Tamás Monostori1, Róbert Bráj2, Andrea Bartók3, Zsolt Gombos4, Adrienn Szarvas1, Ádám Bordé1, Péter Jakab1, Viktor Vojnich1, Zsuzsanna Táborosiné Ábrahám2, Klára Marótiné Tóth2  1 University of Szeged Faculty of Agriculture, Hódmezővásárhely, Hungary 2 Hungarian University of Agriculture and Life Sciences, Institute of Horticulture, Szeged, Hungary 3 agricultural engineer, Tiszasziget, Hungary 4 horticultural engineer, Tiszasziget, Hungary   The main objective of our EIP-AGRI project is to eliminate the yield stability problems regularly occurring in sweet potatoes, by elaborating site- and cultivar- specific technological solutions based on experimental results covering most aspects of cultivation. In parallel, the cultivar-specific adaptation and integration of the in vitro micropropagation method can make the first step towards establishing a pathogen-tested production system of the propagating material. During the first two years (2019-2021) of the 3-year project, the following preliminary results were recorded: - Under the climatic conditions of South-East Hungary, the cultivation of sweet potato in greenhouse is not recommended due to the extremely poor storage root yields achieved. At a large foliage of all the 8 genotypes involved, the yield per plant values were between merely 358 grams (cv. ‘Tápió 96’) and 18 grams (cv. ‘Purple’). In general, the white-fleshed genotypes tolerated the protected growth conditions better.  - The beneficial effect of flat planting compared to ridge planting without mulch cover was detected on sandy soil. The cv. ‘Ásotthalmi12’ yielded 579 vs. 474 g plant-1 in the two cultivation systems, respectively, but the difference was not statistically significant. - Omission of irrigation had significantly negative influence on the storage root yield of cv. ‘Purple’ (drip-irrigated: 2,690 vs. non-irrigated: 1,455 g plant-1). The over-average yield, however, could be achieved due to a beneficial distribution of precipitation in the crop-year. - The hormone composition of the induction media can influence the multiplication rate in in vitro micropropagation. MS-based media both with and without the addition of BAP can result in better results, depending on the sweet potato genotype.  The research was supported by the “VP3-16.1.1-4.1.5-4.2.1-4.2.2-8.1.1-8.2.1-8.3.1-8.5.1-8.5.2-8.6.1-17” Rural Development Program, in connection with the grant document with the identification number 1924527185.
