Sprouting Control Treatment with LED Lights Does Not Affect the Biochemical Aspects of ‘Asterix’ Potatoes Vanessa Maria Dantas Pedrosa, Maiqui Izidoro, Maryelle Barros da Silva, Francisco Ronaldo Cardoso da Silva, Arthur Bernardes Cecilio Filho, et al. Potato Research, 2025 Recently, it was observed that red, blue and far-red lights and different intensities (0.1 and 1.0 μmol m−2 s−1) of light-emitting diode (LED) reduced potato sprout growth but did not effectively inhibit sprouting in physiologically aged tubers. Therefore, this study aimed to identify the physiological and biochemical changes and sprout development in potatoes treated with LED lights or with 3-chlorophenyl carbamate (CIPC). To achieve this, ‘Asterix’ potatoes were harvested, cured at 15 °C (90–93% RH) for 15 days and treated with red (5 µmol m−2 s−1), far-red (5 µmol m−2 s−1) and blue (1 µmol m−2 s−1) LED lights, in addition to the negative control (dark) and positive control (0.022 g L−1 of CIPC) treatments. Potatoes from the light treatments were exposed to LED lights 24 h a day throughout the storage period, under optimal conditions for sprout development (16.7 ± 1 °C and 91.5 ± 1% RH). Tubers treated with blue and far-red LED light exhibited longer dormancy, fewer sprouts and smaller sprouts over the storage period. The carbohydrate content (starch and reducing sugars) was not affected by light treatments; however, total soluble sugar content was lower in tubers kept in the dark and higher in those treated with far-red LED light, which was not related to sprouting control. Therefore, it is suggested that other signalling mechanisms may be involved in sprout control using LED lights.
Biofortification of Arugula Microgreens Through Supplemental Blue Light Franciele Quintino Mendes, Rogério Falleiros Carvalho, Manuela Oliveira de Souza, Arthur Bernardes Cecílio Filho Horticulturae, 2025 Eruca sativa has been widely chosen among species to be cultivated in plant factories as microgreens, especially due to its nutraceutical and sensory qualities. Thus, the objective of this study was to evaluate the impact of blue light intensity (5 and 20 μmol m−2 s−1) and exposure time (1 and 2 h per day) on the yield and quality of arugula microgreens in plant factories. Blue light supplemental to white light for 1 h did not impair the hypocotyl lengths (HLs) or cotyledon area (CA) and yield of arugula microgreens compared with those grown only with white light. However, when the blue light time increased from 1 to 2 h, there were reductions in HL, CA and yield, with greater reductions under 20 μmol m−2 s−1. The concentrations of chlorophylls, carotenoids, vitamin C and antioxidant power responded similarly to the supply of blue light and were maximized with 20 μmol m−2 s−1. In view of these results, the supplementation of blue light with 20 μmol m−2 s−1 for 1 h is proposed, since it did not cause a reduction in growth and yield parameters and promoted the agronomic biofortification of arugula microgreens, bringing nutraceutical and, therefore, commercial benefits to the producer and consumer.
Cumulative Energy Demand and Greenhouse Gas Emissions from Potato and Tomato Production in Southeast Brazil Breno de Jesus Pereira, Newton La Scala, Arthur Bernardes Cecílio Filho Agronomy, 2025 Knowing the energy balance in agricultural systems is essential for a holistic understanding of sustainability, productivity and economic return. The aim of this study was to estimate the cumulative energy demand (CED), greenhouse gas (GHG) emissions and carbon footprint in industrial potato and tomato production systems in the Southeast region of Brazil, identifying mitigation strategies in different scenarios. The Life Cycle Analysis methodology was used, and two functional units were defined: one hectare of cultivation and one kilogram of vegetable produced. The CEDs for tomato and potato production were 59,553.56 MJ ha–1 (or 0.54 MJ kg–1) and 57,992.02 MJ ha–1 (or 1.45 MJ kg–1), respectively. The GHG emissions were 5425.13 kg CO2 eq ha–1 for potato production and 5270.9 kg CO2 eq ha–1 for tomato production, resulting in carbon footprints of 0.135 and 0.042 kg CO2 eq kg–1, respectively. Fertilizers, diesel and pesticides were the main contributors to CED and GHG emissions. Thus, in order to achieve greater sustainability in the production of these vegetables and mitigate the impacts on the environment generated by the high demand for energy and GHG emissions, it is necessary to replace synthetic fertilizers with organic sources, chemical pesticides with biological pesticides, diesel with biodiesel or the use of electric vehicles and tractors, resulting in reductions of up to 39 and 52% in the GHG emissions for potatoes and tomatoes, respectively.
How does sowing density affect physiology, yield, and quality of red cabbage microgreens? Arthur Bernardes Cecílio Filho, Wellington Missiano Pindobeira, Thatiane Nepomuceno Alves, Laura Matos Ribera, María José Yañez Medelo Bragantia, 2025 Red cabbage microgreens, with high nutraceutical value and peculiar sensory characteristics, has been one of the most studied microgreens for cultivation in plant factories, especially under red and blue light irradiance. However, under white light, it is necessary to know the effect of sowing density on their physiology, yield, and quality, which is the objective of the present study. Five sowing densities (60, 120, 180, 240, and 300 g·m–2) were evaluated in an indoor environment under photosynthetic photon flux density of 250 μmol·m–2·s–1 of white light + 20 μmol·m–2·s–1 of red light, and photoperiod of 20 h. Increase in sowing density caused greater competition among seedlings, which increased hypocotyl length and reduced cotyledon area and shoot dry mass of the microgreens. However, the perceived decreases in the individual plant mass were offset by an increase in the number of plants, which resulted in higher yields as sowing density increased. Efficiency of photosystem II, initial fluorescence, and maximum fluorescence were not influenced by sowing density. As for the quality of microgreens, increasing the sowing density resulted in an effect contrary to that observed for yield and reduced contents of calcium, iron, pigments, and ascorbic acid.
Nutritional Diagnosis of Potato Crops Using the Multivariate Method Danilo dos Reis Cardoso Passos, Arthur Bernardes Cecílio Filho, Rogério Peres Soratto, Danilo Eduardo Rozane, Danilo Ricardo Yamane, et al. Agronomy, 2024 The compositional nutrient diagnosis (CND) method considers the multiple relationships among nutrients and has been proposed to evaluate the nutritional status of plants in place of the univariate and bivariate methods. As it is mathematically based and considers the interactions among all nutrients at the same time, it avoids the errors and trends observed in the calculations of other methods estimating nutritional status, enabling a greater relationship with productivity. The objective of this study was to obtain the CND norms for high-yielding populations of potato crops. For this, 587 samples were used from 21 experimental areas in the state of São Paulo, Brazil to correlate the leaf nutrient contents and the yields of potato crops. Crops with yields higher than 48,993.24 kg ha−1 were considered to have high yields, and the Mahalanobis distance separated the balanced samples from the nutritionally unbalanced ones. Thus, the CND-ilr method generated the norms and classified the 587 samples as nutritionally balanced with a high yield (5% of the total), nutritionally unbalanced with a low yield (92%), nutritionally unbalanced with a high yield (0.3%), or nutritionally balanced with a low yield (2.7%), with accuracy, sensitivity, specificity, NPV, and PPV scores of 96.9, 97.1, 93.6, 64.4, and 99.6%, respectively.
Onion quality and yield after agronomic biofortification with selenium Beliza Queiroz Vieira Machado, Breno de Jesus Pereira, Gabriel Fernandes Rezende, Arthur Bernardes Cecílio Filho Chilean Journal of Agricultural Research, 2024 The hidden hunger for Se in the world population is well known. As a strategy to address this issue, this study aimed to biofortify onion ( Allium cepa L.), since it is a condiment vegetable consumed by different economic classes and is widely used in the food industry. To this end, Se doses (0, 10, 25, 50, 100 and 200 g ha -1 ) and application forms (soil and foliar) were evaluated on the biofortification of the bulb and crop yield. The Se source was sodium selenate. Via soil, Se was applied together with NPK fertilizer in the pre-transplantation of the seedlings. Via foliar application, Se was sprayed 77 d after seedlings were transplanted. The Se increased yield up to 99 g ha -1 , which was 14.7% higher than the yield obtained in the crop not fertilized with Se. Foliar application of Se was more efficient than soil application in the biofortification of onion, although both were effective. With the dose that promoted the highest yield, the Se concentrations reached 0.487 and 0.317 mg Se kg -1 in onion dry mass, when the supply was made via foliar and soil applications, respectively. The increase in Se supply did not influence bulb quality, as demonstrated by the macro-and micronutrients content and pungency.
