Gypsum and Potassium Doses on Cauliflower Nutritional Status and Production

Abstract

Gypsum is widely used in agriculture to supply nutrients to the soil-plant system. However, the excessive use of gypsum may lead to a reduction of cationic soil nutrients such as potassium in the most superficial soil layer. Thus, the objective of this study was to evaluate the feasibility of using gypsum and potassium for cauliflower crop nutritional status and commercial production. The experiment was conducted in 5×5 factorial scheme, corresponding to five K doses (0, 100, 180, 240, 360 kg ha−1 of K2O) and five gypsum doses (0, 500, 1000, 2000, 4000 kg ha−1) in dystrophic Red Latosol. Leaf N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn contents, commercial head mass, diameter and height and peduncle diameter were evaluated. The application of 360 kg ha−1 of K2O resulted in 29.69% more K in cauliflower leaf and 18.94% more commercial head mass compared to the non-application of K. The application of 4000 kg ha−1 of gypsum resulted in reductions of leaf S and Mn and increase in leaf Cu. Based on the results observed, 4000 kg ha−1 of gypsum and 360 kg ha−1 K2O could be required for high cauliflower production.

“…Additionally, other agricultural technologies are being developed and implemented to improve crop productivity (yield per area) and the sustainability of the agricultural activity, and indeed, they will affect the soil and plant responses and the agronomic recommendations for gypsum management. Such improved technologies include (i) smart fertilizers (e.g., slow and controlled release fertilizers, bioformulated fertilizers, nanofertilizers, beneficial nutrients) developed to enhance nutrient use efficiency and crop yield with low impacts on the natural environment (Raimondi et al, 2021;Karthik and Maheswari, 2021;Tayade et al, 2022;Verma et al, 2022;Abiola et al, 2023;Areche et al, 2023;Chakraborty et al, 2023); genetic engineering and genome editing techniques of crop plants to improve their resistance to stresses and use-efficiency of agricultural amendments (Jan and Shrivastava, 2017;Mackelprang and Lemaux, 2020;Clouse and Wagner, 2021;Lebedev et al, 2021;Raza et al, 2022); large-scale application of artificial lights (light supplementation) to field crops (Lemes et al, 2021), and digitalization-integration-robotization plus AI (artificial intelligence), DL (deep learning) and blockchain of agriculture (Krithika, 2022;Srivastava, et al, 2022;Adamides and Edan, 2023;Ali et al, 2023;Mahibha and Balasubramanian, 2023;Cheng et al, 2023;Mesías-Ruiz et al, 2023;Okolie et al, 2023;Wakchaure et al, 2023;Zeng et al, 2023) are emerging and represent some of the most recent advances for modern sustainable and productive agriculture.…”

“…Many horticultural crops, for example, presented improved yield, quality, shelf life, and profitability when gypsum is applied (Korcak, 1993;Brown, 2018;Lantzke, 2018;Charlo et al, 2021;Watts et al, 2021). Even crop production in soilless growth media can benefit from gypsum.…”
