“…They also observed that the macronutrient content followed the sequence N>K>Ca>S>Mg>P, and micronutrients followed the sequence Fe>Mn>Cu>Zn>B. Differences in the crop management (e.g., nutrition, irrigation, genotype), as well as soil differences, can affect the results of the experiments; however, the differences between the results observed by Berça, Mendonça and Souza (2019) [16] and the results of the present study are probably due to the time of evaluation of the cabbage leaves. In both experiments, the macronutrients N, Ca and K, and the micronutrients Fe and Mn were the most accumulated by cabbage leaves.…”

Among the most absorbed nutrients by cabbage, nitrogen (N) and potassium (K) are the most extracted; thus, the objective of this study was to evaluate the responses of N and K fertilization on the cabbage biometrics and foliar levels of macro and micronutrients. Four N doses (0, 75, 150, 300 kg ha -1 of N) and four K doses (0, 75, 150, 300 kg ha -1 of K2O). Biometrics of cabbage head (height, circumference and diameter) and productivity were evaluated. The cabbage levels of macro and micronutrients were also evaluated in leaves of plants at the phenological stage of head-formation. Nitrogen fertilization did not significantly affect the variables evaluated mostly due to the great natural fertility of the experimental soil area. This lack of response highlights the importance of constant monitoring of the nutritional status of the productive area to avoid nonnecessary N fertilization. The lowest Mg leaf content was observed at 88 kg ha -1 of K2O, after which the Mg leaf content increased. The foliar Zn was reduced in doses after 133 kg ha -1 of K2O. The cabbage head diameter and circumference decreased with the increase of the K2O doses. The cabbage head height increased up to 128 kg ha -1 of K2O. The decreasing sequence of the macro and micronutrient levels in cabbage leaves followed the sequence K>Ca>N>S>Mg>P and Mn>Fe>B>Zn>Cu regardless of the level of the factors applied. Keywords: Brassica oleracea var. capitata, crop yield, plant mineral nutrition Entre os nutrientes mais absorvidos pela cultura do repolho, o nitrogênio (N) e o potássio (K) são os mais extraídos. Assim, o objetivo deste estudo foi avaliar as respostas da fertilização de N e K sobre a biometria de repolho e os níveis foliares de macro e micronutrientes. Quatro doses de N (0, 75, 150, 300 kg ha -1 de N) e quatro doses de K (0, 75, 150, 300 kg ha -1 de K2O). Foram avaliadas a biometria da cabeça de repolho (altura, circunferência e diâmetro) e produtividade. Os níveis de macro e micronutrientes nas folhas de repolho também foram avaliados na fase fenológica da formação da cabeça. A fertilização nitrogenada não afetou significativamente as variáveis avaliadas principalmente devido à grande fertilidade natural da área experimental do solo. A falta de resposta destaca a importância do monitoramento constante do estado nutricional da área produtiva para evitar fertilizações nitrogenadas desnecessárias. O menor teor foliar de Mg foi com a aplicação de 88 kg ha -1 de K2O, após esta dose o teor foliar de Mg aumentou. O Zn foliar foi reduzido em doses superiores s 133 kg ha -1 de K2O. O diâmetro da cabeça de repolho e a circunferência diminuíram com o aumento das doses de K2O. A altura da cabeça do repolho aumentou com a aplicação de até 128 kg ha -1 de K2O. A sequência decrescente dos níveis de macro e micronutrientes nas folhas de repolho seguiu a sequência K>Ca>N>S>Mg>P e Mn>Fe>B>Zn>Cu independentemente do nível dos fatores aplicados.

“…Both plant and plastic mulching reduce water consumption for irrigation by increasing the irrigation efficiency and reducing evapotranspiration, thus resulting in higher profitability (Berça et al, 2019;Carvalho et al, 2018;Lima et al, 2017).…”

Rentabilidade de cenoura orgânica influenciada por manejos de solo e tipos de semeadura

et al. 2023

A avaliação econômica da atividade agrícola é importante para determinar sua viabilidade. Assim o objetivo deste trabalho foi verificar a rentabilidade econômica do cultivo orgânico de cenoura, sob manejos de solo e diferentes semeadura. O experimento foi realizado em Rio Branco, AC, entre junho e setembro de 2018. Instalado em delineamento em blocos casualizados, em parcelas subdivididas, sendo quatro manejos: cobertura vegetal morta, cobertura plástica “mulching”, solarização e solo nu; e três tipos de semeadura: direta, indireta e pré-germinada. Aos 81 dias foi realizada a colheita e após a avaliação da produtividade, foram avaliados os indicadores econômicos: custos, receitas, rentabilidade, margem de lucro, remuneração de mão-de-obra familiar e produção para cobertura de custos. Considerando os custos com insumos e serviços vigente em 2018 e os coeficientes técnicos obtidos durante o experimento. A margem de lucro foi superior a outros investimentos, como a poupança. Todos os tratamentos tiveram rentabilidade positiva, bem como para todos a relação B/C foi superior a 1,0. A proteção do solo com plástico “mulching” proporcionou as maiores receitas. A diária paga à mão-de-obra da família alcançou R$ 621,26. A solarização com semeadura indireta exigiu maior produtividade para cobertura do custo total. Independente do manejo do solo e tipo de semeadura, a rentabilidade é positiva e apresenta lucro supernormal. A cobertura plástica “mulching” aliada a semeadura direta e pré-germinada, elevam as receitas.

“…However, more recent experiments report show that inorganic mulch material such as black plastic had significant effect on cabbage size and yield compare to organic mulch material such as wheat straw while no mulching gave least output (Chantal, 2021). Although, under greenhouse condition the productivity of cabbage was reported not to be affected by mulching but was efficient in reducing evaporation and increased the efficiency of water usage (Berca et al, 2019). The different application of mulching under different cultivation practices, types, their effects, techniques and advantages in specific situation makes this experiment important to establish the right approach to be recommended to cabbage farmers in the South West Nigeria who have recently taken an interest into commercial cabbage production (Agri farming, 2021).…”

The experiment was conducted to examine the effects of mulching and spacing on yield quality of cabbage. The objectives were to determine the appropriate spacing for cabbage, know the effect of mulching on yield quality and measure the combine effect of mulching and spacing on yield of cabbage. The experiment was laid out in a 2 x 5 factorial in Randomized Complete Block Design with three replications. The mulch materials used for the experiments were; black polyethene plastic mulch, gliricidia, Elephant grass, Sunflower, and No mulching (control) while the planting spacing used were (45cm x 45cm and 30 cm x 30 cm). Data collected was subjected to analysis of variance (ANOVA) and means separation was done using Duncan Multiple Range Test (DMRT) at 5% probability level. Result obtained revealed that spacing at 45cm gave the best yield quality with fruit weight (114.36g), fruit height (26.47cm) and girth (48.13cm). Black polyethene (BP) gave the best yield fruit weight (1369.76g), fruit height (29.5cm) and girth (52.33cm). The combined effects of mulching and spacing revealed that combined effect of the factors do not have significant effect on the yield quality of cabbage. Based on the findings spacing of 45 by 45cm and black polyethene mulching materials were recommended for optimum yield quality of cabbage in the region.
