“…Few potato N rate requirement studies capture the environmental and management conditions and challenges of northeastern Florida. Seepage irrigation method, sandy soil type, and spring seasonality all impact the nutritional requirements of this cropping system (Stanley and Toor 2010; Ensign, 1935). In northeastern Florida, Worthington and Hutchinson (2006) found similar cultivar Atlantic yield or tuber specific gravity when grown with 168 or 224 kg ha −1 N, however this study did not evaluate the timing and load of N application common to Florida production.…”

Potato (Solanum tuberosum L.) in Florida is largely produced in sandy soils with low water and nutrient holding capacity, which makes N fertilizer timing and rate key factors for successful crop management. e objective of this study was to determine the e ect of N fertilizer rate and application timing strategy on biomass accumulation, marketable yield, and tuber quality of chipping potato cultivar Atlantic produced in northeastern Florida. Field trials were conducted for three consecutive years on three commercial farms. All plots received 56 kg ha -1 of N before potato planting. Nitrogen fertilizer treatments were 0, 56, 112, or 168 kg ha -1 at plant emergence (N emerg ) combined with 56 or 112 kg ha -1 of N applied as sidedress at tuber initiation (N tuber init ). Aboveground plant biomass showed no response to increasing N at N emerg or N tuber init . Low yield and poor tuber quality were a result of intense rainfall patterns in the rst year. For the other two seasons, marketable yield ranged from 28.7 to 36.1 Mg ha -1 . Nitrogen treatments at emergence were not correlated to an increase in potato yield during the nal 2 yr indicating that under the conditions of these experiments there was no N limitation. Total N applications over 280 kg ha -1 did not increase yield or quality and N tuber init above 56 kg ha -1 had no impact on plant biomass or tuber yield on any farm in any year of this study.

“…Thus, MI was adjusted to have a value between 200 and 1500 mm and calibrated to fit to the actual distribution of areas cultivating potato. The optimum soil moisture for potato cultivation has been reported to vary from 12% to 60% [47], however, there was another study that potato production was inhibited by approximately 12% [48]. As a result, SM0, SM1, SM2, and SM3 were set to be 0.12, 0.2, 0.8, and 1.5, respectively.…”

This study evaluated the potential distribution of the potato tuber moth. This species severely impacts global potato production, especially in China and India, which have the world’s largest potato production. We developed two indices considering host plant availability and production in addition to climatic suitability, which was simulated using the CLIMEX model. Thus, three different indices were used to project potential distribution of the potato tuber moth under a climate change scenario: (1) climatic suitability (ecoclimatic index (EI)) (EIM), (2) climatic suitability combined with host plant availability (EIN1), and (3) climatic suitability combined with host plant production (EIN2). Under the current climate, EIM was high in southern India and central to southern China, while EIN1 and EIN2 were approximately 38% and 20% lower than EIM, respectively. Under the Special Report on Emissions Scenario A1B, the potato tuber moth would probably not occur in India, but its distribution could be extended to the north, reaching N47°. The areas with the highest climatic suitability by potato tuber moth based on three indices were Sichuan and Karnataka in response to climate change. These areas require adequate pest control, such as prevention of spread through transport of potato seed or by using cold storage facilities.
