Summary: An appropriate planting density was found to stimulate cambium cell differentiation, increase carbohydrate accumulation, and inhibit lignin biosynthesis in potential storage roots of sweet potatoes. The D20 treatment resulted in more storage roots, higher yield, and improved commercial features compared to the control treatment. This study provides a theoretical basis for the high-value production of sweet potatoes.

Summary: This study investigated the impact of different potassium fertilizer application rates on sweet potato yield and economic implications. The results showed that increasing potassium fertilizer application did not increase sweet potato yield, but exhibited a quadratic trend within a certain range. The optimal fertilizer recommendation was 174 kg/ha of K2O. This study suggests that potassium fertilizer can be applied at lower rates than the recommended level while still achieving comparable sweet potato yields.

Summary: We identified a sweet potato yield-related gene, IbAPS, and found that it positively affects AGP activity, starch biosynthesis, leaf development, chlorophyll metabolism, and photosynthesis, leading to increased vegetative biomass and storage root yield. IbAPS also affects other storage root development-associated events and plays a crucial role in carbohydrate metabolism, plant growth, and storage root yield.

Summary: The application of potassium (K) significantly improved the biomass accumulation of sweet potato plants and storage roots, while also enhancing photosynthetic capacity. K application resulted in a decrease in sucrose, amylose, and amylopectin content but an increase in starch accumulation, promoting starch accumulation and storage root yield through regulating gene transcription and enzyme activity.

Summary: The study investigated the effects of water deficit levels on growth, yield, and quality parameters of Koganesengan and Beniazuma sweet potato varieties under drip irrigation. Results showed that Beniazuma variety is more sensitive to water deficit than Koganesengan. Both varieties can be grown in Mediterranean conditions with proper irrigation.

Summary: Long-term N fertilization decreased the abundance of the nifH gene significantly and altered the structure and diversity of the soil diazotrophic community. High N fertilization rates reduced the relative abundance of nifH-harboring microorganisms, especially potential N2-fixers like Cyanobacteria. Soil pH had a greater impact on diazotrophic community diversity and structure compared to soil organic matter and nitrogen forms, while soil available phosphorus content mainly regulated diazotrophs abundance.

Summary: The study showed that moderate nitrogen levels promoted root biomass and storage root differentiation in sweet potatoes, while high nitrogen levels inhibited these processes. Under drought conditions, high nitrogen led to decreased root growth and morphological traits.

Summary: This study investigated the storage root formation process in the mutant line C20-8-1, which exhibited inhibition of storage root formation during early growth stages. The root development in C20-8-1 was delayed or inhibited at the transition from fibrous roots to pencil roots, which are the stages prior to mature storage root formation. The upregulation of starch biosynthesis-related genes and downregulation of lignin biosynthesis genes, typically observed during root swelling, were not confirmed in C20-8-1, suggesting that most of the roots in C20-8-1 are in the pre-transition state toward storage root swelling. This mutation in C20-8-1 during the critical period of storage root swelling initiation provides new insights into storage root formation.

Summary: Potassium significantly affects sucrose metabolism and storage root formation in sweetpotato. Appropriate potassium treatment can promote the number and length of adventitious roots in early storage root formation stage, increase enzyme activity, leading to sucrose degradation and fructose accumulation, ultimately increasing yield.

Summary: Sweet potato is highly dependent on arbuscular mycorrhizal fungi (AMF) and potassium (K) for optimizing morphology and nutrient uptake. This study found that AMF inoculation improved root morphology in sweet potato mainly through K application. Additionally, a specific AMF, Claroideoglomus etunicatum (CE), promoted root dry matter accumulation and K allocation in high-KIUE genotype Xu28. These findings provide insights into the interaction between K, AMF, and sweet potato, contributing to the scientific application of AMF in sweet potato cultivation.

Summary: This study investigated the nutrient requirements and effects of fertilization on the soil properties and growth status of Erythropalum scandens seedlings through a series of pot experiments. The results revealed that E. scandens seedlings have a stronger sensitivity to nitrogen levels, and excessive fertilization can lead to soil acidification. Proper fertilization treatments can promote better growth status of the seedlings.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.
