“…Similarly, the treatments T1 to T6 led to RDM values that were 113 to 260% higher than that of the control (Table 6). The results obtained by any of the alternative treatments were higher than the maximum found by Costa Júnior et al (2017) at 65 DAS (1.2 g), Oliveira et al (2015) at 40 DAS (0.4 g) and Almeida et al (2018b) at 60 DAS (0.26 g), in Formosa papaya seedlings.…”

“…The results obtained in this study were relatively lower than those obtained by Silva et al (2018b), in the Midwest region, who evaluated the formation of papaya seedlings in different organic substrates and found a maximum number of leaves of 7.8 leaves, at 90 DAS. Similarly, the results were also lower than those obtained in the Northeast region by Costa Júnior et al (2017), who found values between 6 and 9 units at 65 DAS, and those obtained also in the Northeast region by Oliveira et al (2015), who observed values between 5 and 11 units, approximately, at 40 DAS. This may be related to the climatic conditions of the regions where the above-mentioned studies were carried out because, as these regions have higher average temperature, the quality and intensity of light influence the development of the plant.…”

“…In addition, the results obtained in this study (6.64 to 7.38 mm) were also higher than those obtained by Costa Junior et al 2017, who obtained a maximum SD of 5 mm, and by Almeida et al (2018b), who obtained a maximum SD of 5.51 mm, in Formosa papaya seedlings, at similar DAS. Oliveira et al (2015), analyzing the production of Formosa papaya seedlings under different doses of sheep manure, found that plants fertilized with 60% manure showed a 146.2% increase in SD in comparison to those that were not fertilized with manure, demonstrating that the use of organic substrates is an interesting alternative in the production of Formosa papaya seedlings. The authors did not obtain SD greater than 6 mm, although the seedlings were evaluated earlier (40 DAS) compared to this study (59 DAS).…”

Using residues generated in agriculture to produce seedlingsis an economically interesting alternative, besides being a way to reduce the environmental impacts caused by their inadequate disposal. This study aimed to evaluate the potential of using coffee chaff (CC) and organic compost (OC) as substrate components for the production of Formosa papaya seedlings and the potential of grape pomace (GP), a vitiviniculture residue, in the composition of substrates for the production of okra and zucchini seedlings. We carried out two trials in a completely randomized design (CRD): the first had seven treatments and six replicates: T0: 100% commercial substrate Bioplant® (CS); from T1 to T6: increasing proportions of CC and decreasing of CC: 10/90; 20/80; 30/70; 40/60; 50/50 e 60/40%. The second had six treatments and six replicates, with increasing proportions of GP and decreasing proportions of CS: 0/100; 10/90; 20/80; 30/70; 40/60 and 50/50%.In the first trial we evaluated the number of leaves, root length, seedling height, stem diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI) at 59 days after sowing.The second trialwas performed at 12 and 18 DAS and we analyzed the number of leaves, plant height, root length, collar diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI). Variables that met the assumptions of normality and homoscedasticity were subjected to Dunnett’s test. The substrate composed of coffee chaff and organic compost has a high potential to be used as an alternative substrate due to promote better quality of papaya seedlings compared to the commercial substrate. Alternative substrate containing 60% coffee chaff and 40% organic compost is recommended for the production of Formosa papaya seedlings in tubes. The grape pomace (GP) has a high potential to be used as component in substrate for the production of okra and zucchini seedlings compared to the commercial substrate (CS) only. Alternative substrate composed of 50% GP and 50% CS is recommended for the production of zucchini seedlings, while substrate composed of 10% GP and 90% CS is recommended for the production of okra seedlings.

“…A dose de 40% de esterco ovino promoveu o maior NFP, estimado em 25,2 (figura 1), estando esse resultado relacionado à maior disponibilidade de nutrientes nesses substratos. Tais resultados são semelhantes aos encontrados por Oliveira et al (2015), que constataram incremento de 107,7% no NFP de mudas de mamoeiro formosa com a utilização de 60% de esterco ovino na composição do substrato.…”

O sucesso da cajucultura depende da produção de porta-enxertos vigorosos, sendo necessário o uso de substratos ricos em nutrientes disponíveis para produzir mudas robustas. Objetivou-se avaliar a produção e a qualidade de porta-enxertos de cajueiro-anão-precoce sob diferentes doses de esterco ovino. Foi utilizado o delineamento de blocos casualizados com cinco doses de esterco ovino (0, 10, 20, 30 e 40% do volume total do recipiente) e quatro repetições. Foram determinadas as seguintes variáveis: altura de plantas, diâmetro do caule, número de folhas, massa seca da parte aérea, do sistema radicular e total, relação entre a altura da planta e o diâmetro do caule, relação entre a massa seca da parte aérea e a do sistema radicular, relação entre a altura e a massa seca da parte aérea e índice de qualidade de Dickson. A dose de 40% de esterco ovino ao substrato proporcionou o maior número de folhas por planta, diâmetro do caule e massa seca da parte aérea, do sistema radicular e total dos porta-enxertos, que foram sendo considerados aptos à realização da enxertia. O melhor substrato para a formação de porta-enxerto de cajueiro é constituído de 60% de solo e 40% de esterco ovino.

“…Esta resultância certamente é devido a melhor estruturação do solo, causada pela matéria orgânica e a influencia do nitrogênio, que desempenha uma função vital a planta, visto que o esse nutriente o algodoeiro retira do solo em maior proporção (SILVA et al, 2008). Outrossim, a incorporação de estercos em solos aumenta os teores de matéria orgânica, proporcionando maior capacidade de armazenamento e disponibilidade de água as plantas, bem como a aeração do solo e o desenvolvimento das raízes (OLIVEIRA et al, 2015), melhorando, dessa forma, a estruturação do solo salino-sódio, que por sua vez são desestruturados e impermeáveis (SILVA et al, 2014).…”

RESUMO:A pesquisa foi conduzida em ambiente protegido no CCTA/UFCG onde objetivou-se avaliar o crescimento de plantas de algodoeiro de fibra naturalmente colorida cv. BRS Topázio, no segundo ciclo produtivo pós-poda, em solos salinosódico sob esterco bovino. Usou-se o delineamento de blocos casualizados em esquema fatorial 5 x 4, com 3 repetições, cujos tratamentos consistiram de cinco percentagens de sódio trocável -PST (13,6; 22,4; 30,1; 39,0 e 48,0%) e quatro doses de esterco bovino (0; 5; 10 e 15%). Ao encerrar a produção das plantas de algodoeiro (primeiro ciclo) realizou-se uma poda drástica, onde, após as brotações (segundo ciclo) avaliaram-se aos 51 e 91 dias após a poda (DAP) as variáveis: comprimento do ramo (CR), diâmetro do ramo (DR), diâmetro do caule (DC) e número de folhas (NF). Doses de 10% de matéria orgânica favoreceu o comprimento do ramo e, de 15% o diâmetro do ramo e do caule de plantas de algodoeiro cv. BRS Topázio aos 51 e 91 dias após a poda. Percentagens de sódio trocável de até 48% não influenciou o comprimento e o diâmetro de ramos, o diâmetro do caule e o número de folhas do algodoeiro aos 51 e 91 dias após a poda. A interação entre os fatores (PST x MO) promoveu efeito significativo sobre o diâmetro do caule de plantas de algodoeiro aos 91 DAP. Palavras-chaves:Gossypium hirsutum L., Sódio trocável, adubo orgânico. SUMMARY:The research was conducted in protected environment in the CCTA / UFCG which aimed to evaluate the growth of naturally colored hp fiber cotton plants. BRS Topaz, the second post-pruning production cycle in saline-sodic soils manure. It used the randomized block design in a factorial 5 x 4, with 3 repetitions and the treatments consisted of five percentages of exchangeable sodium -PST (13.6; 22.4; 30.1; 39.0 and 48.0 %) and four doses of cattle manure (0, 5, 10 and 15%). To cease production of cotton plants (first cycle) held a drastic pruning, where, after the shoots (second cycle) were evaluated after 51 and 91 days after pruning (DAP) variables: branch length (CR), branch diameter (DR), stem diameter (DC) and number of leaves (NF). Doses of 10% organic matter favored branch length and 15% of the diameter of the branch and cotton plants cv stem. BRS Topaz after 51 and 91 days after pruning. Exchangeable sodium in percentages of up to 48% did not influence the length and diameter of branches, the stem diameter and the number of cotton leaves at 51 and 91 days after pruning. The interaction between the factors (PST x MO) has promoted significant effect on stem diameter of cotton plants at 91 DAP.
