“…Vieira et al (2020), working with the production of vegetable seedlings under seed magnetization and the use of magnetized water, found higher values for shoot dry mass for the treatment in which seedlings were irrigated with water treated with an Irrifes magnetizer (0.15 T). Pradela et al (2018), working with a Sylocimol Rural magnetizer, found a significant difference for shoot dry mass for the lettuce crop, the result being superior for the treatment using magnetization. The different magnetization levels used in seed treatment and irrigation did not affect the seed vigor variable at the 5% level (Table 9).…”

Corn is one of the most economically important crops in Brazil, and sowing it requires special attention to soil water availability. Magnetized water irrigation is an alternative to irrigation and seed treatment. Thus, the objective of this work was to evaluate the germination of corn seeds treated and irrigated with magnetized water. The experiment was carried out in May 2021 in a greenhouse at Fazenda Água Limpa, belonging to the University of Brasília (UnB). Corn seeds were subjected to four irrigation treatments with magnetized water, namely: magnetic induction of 0.28 T (T1), 0.229 T (T2), 0.029 T (T3) and 0 T (control). The variables evaluated were germination percentage, mean germination time, fresh seedling mass, dry seedling mass and seedling vigor. The design used was completely randomized, with five replications. Water magnetization was performed using three magnetizers, Jiangsu YLD Water Processing Equipment Co. Ltd. (T1), Structured Water Agriculture Magnetizer (T2) and Magnetizer Industrial Technologies Inc. (T3). The studied levels of magnetic induction in the irrigation water, as variables germination percentage and seedling vigor, differentiated among themselves at the level of 5%. Mean germination time, seedling fresh mass and seedling dry mass did not differ between treatments.

A formação de mudas saudáveis e de qualidade é de fundamental importância para o cultivo desta cultura, uma vez que garante maior eficiência e resistência da planta às condições edafoclimáticas. Tendo em vista a importância do boro (B) para Corymbia citriodora no desenvolvimento inicial e a sua escassez nos solos, o presente trabalho objetivou-se em avaliar os benefícios da fertilização deste micronutriente em plântulas da espécie Corymbia citriodora. Foi considerado o delineamento experimental inteiramente casualizado, compreendido por 5 tratamentos de doses de B na forma de ‎H3BO3 (0,0; 0,25; 0,50; 0,75; e 1,0 mg L-1). De forma geral, nas condições em que foi cultivada a espécie Corymbia citriodora, a dose de 0,5 mg L-1 de B foi a que proporcionou os maiores incrementos para os parâmetros do diâmetro do caule; comprimento da parte aérea e da raiz; e massa seca da parte aérea e da raiz. No tratamento com ausência do B (controle), foram detectados os menores incrementos para os parâmetros avaliados, evidenciando que a fertilização com B é benéfica nessas condições de cultivo.

Objective: This study aimed to evaluate the effects of seed magnetization (SM) and irrigation water (WI), using commercial (CO) and Neodymium (NEO) magnetizers, on the development of seedlings of lettuce, eggplant, cucumber, sweet pepper and okra. Method: The experiment was conducted in a randomized block design, with 5 treatments for each species, with 4 replications, being T1: irrigation with non-magnetized water; T2: SM-NEO + non-magnetized water; T3: SM-CO + non-magnetized water; T4: non-magnetized seeds + WI-NEO; and T5: non-magnetized seeds + WI-CO. The following were evaluated: emergence speed, emergence time, percentage of emergence, dry matter, root length, stem diameter, number of leaves and plant height. Result and conclusion: For lettuce, WI-NEO showed the best results and, for sweet pepper, SM-CO, irrigating with non-magnetized water. For cucumber, SM or WI provided a reduction in seedling formation time. For eggplant and okra, we recommended SM-NEO and irrigated with non-magnetized water. In general, seed magnetization caused better results than irrigation water magnetization. Implications of research: Quality seedlings produced in short time and at low cost are of great importance for the formation of vegetable crops. Originality/value: Seed magnetization and the use of magnetized water are innovative, low-cost technologies for producing seedlings of high vigor and quality.
