Ítem Cashew gum hydrogel as an alternative to minimize the effect of drought stress on soybean(2024-01-25) Ratke, Rafael Felippe; De Sousa, Alan; Vieira Chaves, Daniela; Zanatta, Fábio Luiz; Loiola Edvan, Ricardo; Rodrigues Sousa, Heldeney; Cavalcanti Silva Filho, Edson; Anteveli Osajima, Josy; Silva Santos Nascimento, Ariane Maria; González Aguilera, Jorge; Zuffo, Alan Mario; Pereira da Silva, Natielly; Teodoro, Paulo Eduardo; Rocha Bezerra, Leilson; Soto Gonzales, Hebert Hernán; Morales Aranibar, LuisThe use of hydrogels helpsthe production of plants in drought-stress environments. Thus, this work evaluated using different hydrogels to minimize drought stress in soybean cultivation. The treatments employed two different hydrogels, one already commercialized and the other produced with cashew gum (Anacardium occidentale), five levels (0, 30, 60, 120, and 240 mg pot−1) of the hydrogels, and two levels of drought stress in sandy soil. The growth and yield of soybeans and the levels of macro- and micronutrients in soybeans were evaluated.growth. The use of CG hydrogel promoted 12% increase in protein content in the seeds in the when soybean plants were subjected to drought stress. The levels of 30 mg pot-1, corresponding to 7.5 kg ha−1, improved the ’morphological and productive parametersof the soybeans. The increasing levels of hydrogel promoted the increase in P, K, Ca, Mg, and Fe and reduced S and Cu on an exponential scale. The use of cashew gum hydrogel increased the K and Ca contents in soybean seeds compared to commercial hydrogel.
