Result of arbuscular mycorrhizal fungi on growth and yield of pre-basic seed (G0) potato ‘Atlantic’ cultivar

Abstract

     The purpose of this research was studied the result of arbuscular mycorrhizal fungi (AMF) on growth and yield of pre-basic seed (G₀) potato ‘Atlantic’ cultivar. The experiment was conducted in greenhouse of Chiang Mai Agricultural Research and Development Center (CMARDC), Pong Nam Ron, Fang, Chiang Mai in winter season (January-March 2019). The experimental design was a randomized complete block design (RCBD) with four replications. Six AMF dose, 0, 1, 2, 3, 4 and 5 g, were mixed into 1 kg of media before planting the minitubers. The results showed that all dose of AMF were not affected on height, number of branch, and canopy size of 60 DAP potato plant. The longest root with an average of 33.13 cm was investigated in the media mixed with 5 g of AMF treatment. For yield observation on 90 DAP, tuber weight, tuber diameter, tuber weight per plant, and firmness were not significantly different in all treatment, while the highest number of tuber with an average of 3.88, 3.50, and 3.62 tubers/plant was observed in the media mixed with 3, 4, and 5 g of AMF treatment, respectively. In addition, the lowest number of tuber with an average of 2.13 tubers/plant was found in the media without AMF. Keywords: potato, arbuscular mycorrhizal fungi, G₀
