Summary: Reducing nitrogen supply in nutrient solutions can decrease plant biomass accumulation and increase yield. The study found that there is cultivar specificity in nitrogen management when cultivating potatoes aeroponically, with Agata plants showing increased minituber yield with nitrogen reduction while Asterix plants were affected in biomass accumulation.

Summary: Precise diagnosis and prognosis of phosphorus (P) nutrition are crucial for improving P use efficiency and sustainability in potato cropping systems. This study assessed the variable responses of potato crops to different soil P-resin (SPresin) and potato leaf P (LP) concentrations in tropical Oxisols. The results provide important thresholds for optimizing P management and maximizing tuber yield while minimizing environmental P contamination.

Summary: The study aimed to evaluate the effect of magnesium dose on the morphological characteristics of plants and seed potato yield in two cultivation systems. The results showed that besides magnesium content in the fourth leaf dry mass, no other characteristics in both experiments responded significantly to magnesium dose. The highest seed potato yield was obtained in the control experiment and with a dose of 0.96 mmol L-1 in the second experiment.

Summary: Proper irrigation and fertilization are crucial for achieving high yield and quality in potato production. This study investigated the impact of irrigation and nitrogen fertilization on potato yield, quality, and water use efficiency. Results showed that irrigation had a greater influence on potato yield and growth than nitrogen levels. Full irrigation with 300 kg N ha(-1) resulted in the highest total tuber yield, while low irrigation treatments led to significantly lower yields. However, the 66% field capacity irrigation treatment consistently had the highest water use efficiency.

Summary: Freezing severely affects potato production. Understanding the pathways and metabolites that regulate potato's freezing tolerance is beneficial for cultivation and breeding purposes. In this study, it was found that Solanum acaule is more freezing tolerant compared to S. tuberosum. Through RNA-seq and metabolomics analysis, it was discovered that S. acaule activated different genes and enriched certain pathways, such as the hormone signaling pathway involving salicylic acid. Further analysis showed that the content of salicylic acid increased in S. acaule after exposure to cold conditions, leading to improved freezing tolerance. Additionally, the application of salicylic acid to potato enhanced freezing tolerance and increased the expression of HSFC1.

Summary: The study investigated the use of a mixture of lytic bacteriophages to protect potatoes from the pathogenic bacteria, Dickeya solani. Laboratory and field experiments showed that the phage treatment significantly reduced soft rot symptoms and improved leaf cover and tuber yield. The findings suggest that the phage mixture has the potential to effectively protect potatoes from D. solani infection.

Summary: In this study, 144 tetraploid potato genotypes were evaluated to investigate the variation of physiological and agronomic traits under control and water stress conditions. A total of 18 SNP markers significantly associated with these traits were identified, providing insights into the mechanisms of potato tolerance to water stress and potential markers for marker-assisted selection programs.

Summary: This study presents a reliable and efficient method for eradicating viruses in potatoes, which is more effective than current methods. Through testing various treatments, the combination of chemotherapy and cryotherapy, or consecutive chemotherapy, combined chemotherapy and thermotherapy, followed by cryotherapy, showed the best results in virus eradication. This improved method has the potential to produce virus-free planting material for the potato industry and facilitate the exchange of virus-free germplasm globally.

Summary: Due to climate change, water availability has become a major limiting factor in potato production. This study analyzed the differential response of physiological and yield components in six potato varieties under water deficit conditions and found that Monalisa showed the best response in tuber production under stress conditions. Indirect selection based on parameters associated with water stress can be a useful tool in potato breeding programs for the identification of more tolerant varieties.

Summary: This article reviews recent scientific research on microgreens, particularly the impact of artificial lighting on their growth. By analyzing scientific publications from 2000 to 2021, it is found that research on microgreens and artificial lighting has been increasing over the years, with some research gaps identified. Furthermore, there is a lack of studies on the distribution of environmental factors in controlled microgreen cultivation.

Summary: The use of advanced seedlings in annual cultivation of passion fruit is important for managing the FEV virus, but information on nitrogen fertilization and plant spacing is still needed. A nitrogen dose of 130.7 kg ha(-1) and a plant spacing of 2x3 m were found to be the most suitable for maximizing productivity and fruit quality for yellow passion fruit in annual orchards.
