Sources and splitting of the organic fertilization in top dressing in cabbage production

Abstract

<jats:p>ABSTRACT Although there exist researches about fertilization in top dressing in the production of cabbage, these are usually made with inorganic fertilizers, being rare the researches with organic fertilization in top dressing in the production of most vegetables. The objective was to evaluate the effect of different splitting of two organic fertilizers in top dressing in the production of cabbage. Six treatments were evaluated, with four replications in randomized block design. The six treatments were the result of the factorial 3x2, with three types of splitting (1/3+1/3+1/3; 4/6+1/6+1/6; 1/6+4/6+1/6 of the total dose in each application) and two organic fertilizers (castor bean cake and organic compost). The total dose of each fertilizer was calculated to apply 120 kg ha-1 N. The evaluated characteristics were number of external leaves, fresh weight of external leaves (g), fresh and dry head weight (g), head diameter (cm) and length (cm), yield and crop cycle (days after transplanting). Fertilization with castor bean cake resulted in greater yield, producing heads with higher weight, diameter and length in relation to the organic compost, besides reducing the cycle. The 4/6+1/6+1/6 splitting was better than the 1/6+4/6+1/6 splitting using castor bean cake.</jats:p>

Organic fertilizer doses for top-dressing fertilization in jambu (Acmella oleracea [(L.) R. K. Jansen]) production

“…Production increases with the use of these organic fertilizers have been reported in several vegetables grown under tropical and subtropical conditions (Lanna et al, 2017;Silva et al, 2018;Souto et al, 2018;Cardoso et al, 2020).…”

“…In organic fertilizers rich in nitrogen such as castor Nepomuceno Alves et al (2024) Organic fertilizer doses for top-dres... bean cake and hoof and horn powder, fertilization should be applied in a way to avoid excess nutrients in the soil solution (Candian, 2018;. The speed of nutrient release by organic fertilizers should be according to the crop demand (Cardoso et al, 2020).…”

“…However, despite castor bean cake and hoof and horn powder being fertilizers with great potential, which has already been proven for different vegetables (Silva et al, 2016;Cardoso et al, 2020;Lanna et al, 2020;Almeida et al, 2021;Hounmenou et al, 2021, more studies are needed to allow the recommendation of the best fertilizer and doses, aiming to increase crop productivity and reduce costs. The objective of this study was to evaluate the effect of doses of the organic fertilizers castor bean cake and hoof and horn powder on jambu plant production in an organic system.…”

Effects of Nutrient Enriched Municipal Solid Waste Compost on Yield and Nutrient Content of Cabbage in Alluvial Soil

“…Vimala, et al [25] and Hasan and Solaiman [26] also reported positive effect of the conjunctive use of organic and inorganic sources of nutrients on the growth and yield of cabbage (Brassica oleracea). Cardoso et al [27] studied two sources of organic fertilization in cabbage production and observed greater yield, head weight and diameter in case of use of castor bean cake compared to the organic compost. As stated by Ayilara et al [28], addition of activators (e.g.…”

Production of Chives Using Organic Fertilizers before Planting and in Top Dressing

“…As for most species, in chive there are no top-dressing organic fertilization recommendations, only inorganic ones. Among the options of organic fertilizers used by vegetable producers in top dressing application are castor bean cake and hoof and horn powder [12,13,11,3,8] Castor bean cake is widely used as a source of nitrogen, which is a nutrient that plants need in large quantities [11,9]. Organic residues from the processing and slaughter of cattle, sold in the form of hoof and horn powder is also an alternative source of nitrogen.…”
