Abstract
The growing interest in sweet potato among Hungarian consumers and producers makes it necessary to improve crop yield and yield stability.
Within the framework of an EIP-AGRI project, one of our basic goals was the development of site- and genotype-specific technological solutions.
The experiments were carried out in southeastern Hungary, primarily with the registered cultivar ‘Ásotthalmi12’. Cultivation without ridges resulted in higher yield on sandy soil.
Under the climatic conditions of the region, cultivation of sweet potato in greenhouse resulted extremely poor storage root yields (max. 358 g plant‑1). Total lack of irrigation had significant negative effect on root yield, but the beneficial distribution of precipitation in the crop-year could still generate an economic return (1,455 g plant‑1). For the same length of growing period (ca. 130 days), early planting (and harvesting) resulted in significantly higher yield (2,355 vs. 1,100 g plant‑1). Lifting vines did not have a significant positive effect on yield.
Our experimental results and other experiences revealed that sweet potato is a well-adaptable crop with high potential also under the conditions to be expected due to climate change in Hungarian agriculture.
