“…Considering previous research [17,41,42], as well as the low kinetic mobility of Ca in the phloem and the limited redistribution in plants, Agria and Rossi varieties were used as a test system to assess the interactions of foliar fertilization with increasing concentrations of CaCl 2 and Ca(NO 3 ) 2 and the accumulation of mineral elements (Ca, P, K, Na, Fe, Zn, C, H, O, Mn and Cu) in the different tissues of tubers.…”

Calcium is essential for plants, yet as its mobility is limited, the understanding of the rate of Ca2+ accumulation and deposition in tissues of tubers, as well as the interactions with other critical nutrients prompted this study. To assess the interactions and differential accumulation of micro and macronutrients in the tissues of tubers, Solanum tuberosum L. varieties Agria and Rossi were cultivated and, after the beginning of tuberization, four foliar sprayings (at 8–10 day intervals) with CaCl2 (3 and 6 kg ha−1) or Ca(NO3)2 (2 and 4 kg ha−1) solutions were performed. It was found that both fertilizers increased Ca accumulation in tubers (mostly in the parenchyma tissues located in the center of the equatorial region). The functioning of the photosynthetic apparatus was not affected until the 3rd application but was somewhat affected when approaching the end of the crop cycle (after the 4th application), although the lower dose of CaCl2 seemed to improve the photochemical use of energy, particularly when compared with the greater dose of Ca(NO3)2. Still, none of these impacts modified tuber height and diameter. Following the increased accumulation of Ca, in the tubers of both varieties, the mean contents of P, K, Na, Fe, and Zn revealed different accumulation patterns. Moreover, accumulation of K, Fe, Mn, and Zn prevailed in the epidermis, displaying a contrasting pattern relative to Ca. Therefore, Ca accumulation revealed a heterogeneous trend in the different regions analyzed, and Ca enrichment of tubers altered the accumulation of other nutrients.

The nutritional status of the plants, soil chemical attributes prior to vine killing, and the classi ed yield of tubers may characterize soil-plant interactions with nitrogen (N) side-dressing for potato cultivars, indicating the most appropriate source and rate at sidedressing in subtropical environment. Two experiments with potato cultivars Agata and Atlantic were carried out with the aim of evaluating the effect of N sources (urea, ammonium sulfate and calcium nitrate) and rates (70, 140 and 210 kg ha − 1 ) on sidedressing, plus a zero-N control treatment, in the southern Brazil. Discrete variations on nutrients in diagnostic leaves and on soil chemical attributes in the Agata experiment were not re ected in the maximum average increase of 69.0% (14.2 Mg ha − 1 ) in total tuber yields obtained with 152 kg N ha − 1 as ammonium sulfate or calcium nitrate, which did not differ in AE's. For the Atlantic cultivar, urea rates were practically inert in soil and plant attributes, and the ammonium sulfate rates acidi ed the soil and increased their Al 3+ contents in the ridges, reduced Ca and Mg foliar concentrations and did not increase marketable tuber yields. Calcium nitrate increased foliar N, Ca and Mg concentrations, increasing marketable tuber yields by 26.6% (7.3 Mg ha − 1 ) with 116.7% higher AE than other N sources. In subtropical acidic inceptisols with potentially available Al 3+ , 153 kg N ha − 1 as ammonium sulfate or calcium nitrate for cultivar Agata and 152 kg N ha − 1 as calcium nitrate for cultivar Atlantic are the best options for sidedressing fertilization.
