RESUMO Guavira [Campomanesia adamantium (Camb.) O. Berg], Myrtaceae, é uma frutífera nativa do Cerrado. Suas folhas e cascas apresentam propriedades medicinais, sendo utilizada como: antimicrobiana, anti-inflamatória, antinoceptivo e atividade antioxidante. Desta forma, objetivou-se avaliar o crescimento inicial de plantas de guavira cultivada em diferentes substratos e doses de fertbokashi ®. Para isso, avaliaram-se dois tipos de substratos (100% solo e 50% solo + 50% areia) e cinco doses de fertbokashi ® (0; 0,25; 0,50; 0,75 e 1,0 L ha-1). O arranjo experimental foi em esquema fatorial 2x5, no delineamento de blocos casualizados, com 4 repetições. A unidade experimental foi constituída de seis vasos com capacidade de 5 kg, com 4 kg de substrato e uma planta por vaso, em ambiente protegido por sombrite 50%. O solo utilizado foi Latossolo Vermelho distroférrico, e a areia do tipo grossa, lavada. As mudas foram transplantadas para os vasos com aproximadamente 3 cm de altura e as doses de fertbokashi ® foram aplicadas via fertirrigação, a cada 30 dias até 120 DAT. A maior altura de plantas, número de folhas e diâmetro do coleto, seguiram a mesma tendência, sendo observado máximas de 5,8 cm, 10,9 e 1,66 mm, respectivamente, aos 210 DAT. As raízes da planta de guavira se desenvolveram melhor no substrato composto por solo e areia. Massa seca de caule obteve máxima de 0,43 g planta-1 sob 0,59 L ha-1 de fertbokash ® i. O valor máximo (6,53) de RAD ocorreu sem a aplicação de fertbokashi ® no solo. Houve tendência linear positiva de RPAR, à medida que aumentaram as doses de fertbokashi ®. A análise de componentes principais explicou 76,7% da variabilidade remanescente dos dados. Devido a isso, conclui-se que, as plantas de guavira se desenvolvem melhor em substrato composto por solo mais areia, produzindo mudas mais vigorosas, enquanto que as doses de fertbokashi ® pouco estimulam o crescimento inicial da guavira.
Schinus terebinthifolius Raddi. (pimenteira rosa, Anacardiaceae) é utilizada devido às suas propriedades medicinais e condimentares, com valor agregado no mercado. Apesar disso, há poucos estudos relacionados à propagação vegetativa e custos de produção de mudas da espécie. O objetivo deste trabalho foi avaliar a presença de folhas e uso de bokashi na propagação vegetativa da pimenteira rosa. Avaliaram-se três tipos de estacas caulinares com 0, 1 ou 2 folhas, sem e com adição de bokashi (10 g kg-1) ao substrato, sob sombrite 50%. O arranjo experimental foi em esquema fatorial 3x2, no delineamento de blocos casualizados, com quatro repetições. As maiores porcentagens de brotações foram observadas em estacas sem folhas, sem bokashi (50,0%), aos 35 e 42 dias após o estaqueamento (49,3% e 47,2%, respectivamente); o maior índice de velocidade de brotação foi nas estacas sem folhas (0,5766) e o maior comprimento de brotos (24,37 cm) foi observado com a adição de bokashi ao substrato. Os custos de produção variaram entre R$ 232,07, entre o maior (R$ 2.428,66) com bokashi e o menor (R$ 2.196,59), sem bokashi. A quantidade de folhas e uso de bokashi influenciaram na propagação por estaquia e custos na produção de mudas de pimenteira rosa.
Aims: The aim of this study was to evaluate the effect of types of cuttings and light intensity on cidró vegetative propagation. Place and Duration of Study: Medicinal Plants Garden, Federal University of Grande Dourados (UFGD), Dourados, state of Mato Grosso do Sul, Brazil, September to November 2016. Methodology: The experiment was carried out under two light conditions (shaded and full light), evaluating three types of cuttings (softwood, semi-hardwood and hardwood). Experimental design was a 2 x 3 factorial randomized complete block design (RCBD) with four replications. Results: Hardwood cuttings showed the highest survival rates (86% and 82%), regardless of light. Highest fresh weight (0.6062 g plant-1) and dry mass (0.2987 g plant-1) with a leaf of 44.57 cm2 were from hardwood cuttings, regardless of the light, while the longest root length were those of softwood cuttings under full light. Physiological indices varied as a function of light intensity, The highest values of leaf area ratio (46.11 cm2 g-1) and specific leaf mass (0.0037 g cm-2) occurred in cuttings under full light. Conclusion: The vegetative propagation of cidró can be carried out using the hardwood portion of the cutting branch, under full light.
Increased yield and nutrient content of Tropaeolum majus L.with use of chicken manure 1Nasturtium (Tropaeolum majus L.) is an unconventional plant or vegetable grown for ornamental, food and medicinal purposes. However, information on cultivation of the species involving organic residue is incipient. Therefore, aimed to evaluate plant growth, flower yield, and nutrient contents of leaves and flowers of Nasturtium cultivated with addition of chicken manure. Five doses of chicken manure were studied, applied in the soil incorporated (I) (1, 6, 10, 14 and 19 t ha -1 ) and cover (C) (1, 6, 10, 14 and 19 t ha -1 ) forms, using the experimental array Plan Puebla III, leading to nine combinations of doses and forms of adding the chicken manure, in randomized blocks with four replicates. The greatest plant height (35.75 cm) was achieved at 168 days after transplanting (DAT) under 10 t ha -1 I and 10 t ha -1 C. The greatest yield terms of in number (15.4 million ha -1 ) and fresh (10.45 t ha -1 ) and dry weights (0.849 t ha -1 ) of flowers were found by using doses close to 10 t ha -1 I and 10 t ha -1 C. To obtain the best development and yield of Nasturtium flowers, 10 t ha -1 I and 10 t ha -1 C of chicken manure should be used.
Intercropping with Tropaeolum majus and fertilization with chicken manure on yield...
Organic residue in the substrate and the availability of light influence the production of high-quality seedlings for ex situ cultivation of native forest species. This study aimed to evaluate the effect of doses of chicken manure incorporated in the soil and shading levels on the morphophysiological responses and quality of Alibertia edulis (Rich.) A. Rich seedlings. Five doses of chicken manure (CM) were tested, 0.00, 2.08, 4.16, 6.24, and 8.32 g CM kg-1 soil, under two shade conditions, 0% (full sun) and 50% shading. At 215 days after transplanting, the maximum height obtained for A. edulis was 47.35 cm with 5.64 g CM kg-1 soil under 50% shade. Shaded seedlings had a higher number of leaves. The maximum leaf and root areas were 796.64 and 118.83 cm2 with 5.32 and 4.21 g CM kg-1 soil, respectively, both under 50% shade. Seedlings in 0% shade had lower physiological indices. Shading levels did not affect stomatal limitation, but CM contributed to physiological efficiency. Shoot biomass was higher under 50% shade with higher CM doses. The highest quality indexes occurred with 3.98 and 6.28 g kg-1 CM under 0 and 50% shade, respectively. A. edulis seedlings responded positively to the addition of CM to the soil and presented plasticity under contrasting light conditions. A. edulis seedlings produced under 50% shading with the addition of 6.24 g CM kg-1 soil presented high morphophysiological and seedling quality indicators. The addition of 4.32 g CM kg-1 soil contributed to high seedling quality under full sun conditions.
