“…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).…”

Due to the lack of specific fertilization recommendations for jambu cultivation, producers commonly usefertilizers recommended for other vegetables. This study aimed to evaluate the effect of different doses oforganic fertilizers, namely hoof and horn powder and castor bean cake, on jambu plant production under anorganic system. The experiments were conducted at the Experimental Farm of São Manuel, SP, belonging to theSchool of Agriculture (FCA) – UNESP, and at the “Estância Três Nascentes” site, located in Botucatu, SP, Brazil.Twelve treatments were evaluated, in a 2 x 6 factorial design, consisting of two organic fertilizers (castor beancake (CBC) and hoof and horn powder (HHP)) x 6 top dressing N doses (50, 75, 100, 125, 150, and 0 (controlwithout these fertilizers)). The experimental design was a randomized block with four replications. Plant height(PH), number of inflorescences (NI), the fresh weight of inflorescence (FWI), the fresh weight of vegetative parts(FWVP), and the total fresh weight (TFW) were evaluated at each location. Linear increases were observed in allcharacteristics in both locations as the fertilizer doses increased. Comparing the highest dose (150 kg ha-1 of N)with the control, increases of 109%, 251%, 218%, 283%, and 227% were obtained at the farm in São Manuel, and69%, 79%, 111%, 276%, and 118% in Botucatu, for PH, NI, FWVP, FWI, and TFW, respectively. When comparing thetwo fertilizers, HHP presented better results than CBC for most characteristics in both areas.

“…Therefore, the alternate harvest performed every 15 days after the beginning of the reproductive period could be a viable alternative to increasing production indices. It should also be noted that organic fertilizers release nutrients slowly and for longer, unlike immediate inorganic fertilizers, which explains the similarity between treatments and suggests the need for higher compost levels (Lanna et al, 2017).…”

Amplamente cultivada em diversos países, a vinagreira (Hibiscus sabdariffa) é utilizada para fins culinários, medicinais e ornamentais. Devido à crescente procura por alimentos mais nutritivos e livre de substâncias tóxicas, visando o desenvolvimento de alternativas ambientalmente corretas, o objetivo desta pesquisa baseia-se no cultivo sustentável de vinagreira sob doses de composto orgânico, verificando o desenvolvimento vegetativo, produtivo e os teores nutritivos da cultura. O experimento foi conduzido na Unidade de Horticultura da Universidade Federal do Acre, consistindo na aplicação de quatro doses de composto orgânico, correspondentes aos tratamentos: T1 - 0 (controle), T2 - 200 mL, T3 - 400 mL e T4 - 600 mL, depositadas nas covas de plantio, espaçadas 0,5 m entre si em três linhas de plantio, com aproximadamente 10 m de comprimento, sendo estas distanciadas a 1 m. O delineamento estatístico foi o de blocos casualizados, contendo cinco blocos. Os dados foram submetidos a análise de regressão à 5% de probabilidade. Foram avaliados parâmetros de crescimento, produção e testes físico-químico das folhas. Resultados significativos foram verificados para altura das plantas e número de ramos de vinagreira, sendo as doses 325 mL e 142 mL, consideradas as melhores para proporcionar maior altura (276 cm) e número de ramos (14), respectivamente. Não houve significância entre as dosagens e os parâmetros de produção e análises físico-química das folhas. A aplicação de composto orgânico promove o crescimento em altura e número de ramos de Hibiscus sabdariffa.

“…Interest in organic fertilizers and research demonstrating gains in productivity and better soil characteristics with their use has increased in recent years [4,5,6,7,8]. However, most of this research has been done with fertilizer applied before planting, and researches about organic fertilizers in top dressing are scarce, but most of them has shown the importance of organic top dressing fertilization [8,9].…”

Chives are one of the most popular spice plants in world cuisine. It is usually produced by small producers, often in an organic farming system. However, research with chives in this production system is lacking. The purpose of this study was to evaluate the production of chives with the use of organic fertilizers before planting and in top dressing. Seven treatments were evaluated, resulting from the factorial 2x3+1, with two organic fertilizers (castor bean cake and hoof and horn powder) x 3 application modes (100% before planting; 100% in top dressing; 50% before planting and 50% in top dressing) + 1 control (without these organic fertilizers). The experimental design was in randomized blocks, with five replications and plots of 1 m 2 . The relative index of chlorophyll ("Spad" index), height, number of leaves, fresh and dry weight of the plants were evaluated. All treatments of the factorial were better than the control, showing that these organic fertilizers improve production in chives. It is recommended to use the hoof and horn powder in installments (50% before planting and 50% in top dressing) or 100% in top dressing, the latter option being more interesting for reducing the need for labor, with just one application moment.
