“…Silicon increases tuber yield (Kaya et al, 2006;Shahabifar, 2006;Ansuriet al, 2014;Golmoradi Marani et al, 2017;Gerami & Torabipoor, 2021;Hassanpanah et al, 2022). Hassanpanah et al (2022) by examining the effect of sulphonated silicon nutrient solution with elemental sulfur S8 on potato cultivars, they concluded the use of sulfonated silicon nutrient solution with elemental sulfur S-8 in two forms of foliar spraying at a rate of 3 per thousand and use of 2 kg of solution in 200 liters of water increased tuber yield and water use efficiency.More number of mini-tubers per plant can be produced by repeating one or more harvests during the season (Lommen & Struik, 1992a, 1992b, 1992cLommen, 1995), dense planting in a greenhouse bed (Jones, 1988), hydroponic (Muro et al, 1997;Rolot & Seutin, 1999), aeroponics (Rolot & Seutin, 1999;Nugaliyadde et al, 2005;Kang & Han, 2005;Farran & Mingo-Castel, 2006;Hassanpanah, 2014) and nutrient solution (Gunasena & Harris, 1968;Balamani et al, 1986;Kang & Han, 2005;Brianna, 2006;Hassanpanah, 2014aHassanpanah, , 2014b. This research aims to increase the mini-tuber number and weight per unit areaby using sulphonated silicon nutrient solution with elemental sulfur S8 in potato cultivars and transferring experience and knowledge and new technologies to potato mini-tubers producers for Ardabil province, Iran was implemented during 2022.…”
