Potato is grown in all the continents except Antarctica, and in the USA, it is grown in all the regions. In Florida, potato is mainly grown in north-central areas, and the most found soil type in this region is aquads (Wet, sandy soil with an organic stained subsoil layer). The objective of this study is to evaluate potato plant phosphorus uptake under different sulfur rates. In this study, we conducted the S-P interaction study at two different sites having soil pH ranged from 5.4 to 6.4, CEC ranged from 2.7-7.1, S content range from 9-51 ppm, and P ranged from 36-348 ppm, to understand the P uptake by the crop along with S fertilizer application. In the experiment, we applied five different rates of S 0, 40, 80, 120, and 160 pounds per acre as Gypsum (17%) along with the two different rates of P 50 and 100 pounds through triple superphosphate (TSP) having the 46% P2O5 using randomized complete block design with four replications. Besides the destructive plant sampling, we also recorded the response of the potato crops to the S-P together by using the Holland scientific crop circle active sensor (ACS 435) has the wavelength of 670nm, 730nm, and 775nm to record the observations for the NDVI, NDRE, LAI, and Red edge, at different crop growth stages. The yield will be recorded as the cwt per acre, grading based on tuber size, and specific gravity.
