“…The total N content in N. physalodes increased to 61 DAE, when it reached maximum values, with a subsequent decrease, independent of the N, P and K level in the soil ( Figure 3A). The decrease of the N content in N. physalodes can be explained by the accumulation of 30-51% of the total dry matter in the reproductive organs of this plant from 61 DAE (MATOS et al, 2015), since the N content in these organs was not measured.…”

“…Nicandra physalodes seeds were collected from the experimental field of UFVJM Diamantina-MG. Seed dormancy was broken by immersing and washing in water to remove the mucilage, as described by Matos et al (2015).…”

“…Flowering occurred practically during ever over the N. physalodes life cycle. Plant concentrated flowering at around 61 DAE, when dry matter allocation to the fruits was intensified (MATOS et al, 2015). At that time, the gradual process of yellowing, senescence and abscission of N. physalodes leaves was initiated ( Figure 2B).…”

“…The pictures are illustrative and are not to scale according to the growth stage of the plant. Additional information on N. physalodes growth, such as dry matter allocation pattern, relative growth rate, height and leaf area over the life cycle of N. physalodes were reported by Matos et al (2015).…”

“…Some horticulturists in Diamantina-MG, Brazil, have managed areas infested with N. physalodes by maintaining residues of this plant on the soil, after control, since this practice contributes to the growth of vegetables. N. physalodes growth analysis showed that this plant has a fast cycle, adapts well to fertile soils and has great capacity to accumulate dry matter (MATOS et al, 2015). This indicates that, if N. physalodes is well managed, its residues can contribute to the nutrient supply (through decomposition) and decrease nutrient losses of the soil in areas infested by it.…”

Weed residues can influence nutrient cycling in agroecosystems. Quantifying this potential nutrient source may influence weed control and fertilisation practices. Nicandra physalodes (L.) Gaertn. is a weed with a short life cycle and a great ability to accumulate dry matter. Field observations suggest that N. physaloides residues are easily decomposed in soil. The objective of this study was to evaluate the effect of increasing of N, P and K doses on the growth of N. physalodes, as well as the nutrient content, chemical characteristics and C/N ratio of the weed. A randomised block design, arranged in split-plot with three replications, was utilised. The main plots were given four doses of NPK (Dose 1 - 0, 0.3 and 17.2 mg dm-3; Dose 2 - 30, 450.3 and 75.4 mg dm-3; Dose 3 - 60, 900.3 and 133.4 mg dm-3; and Dose 4 - 120, 1800.3 and 249.68 mg dm-3), and the subplots were harvested at ten time points after emergence (26, 33, 40, 47, 54, 61, 76, 91, 106 and 121 days). Higher dry matter production and N, P and K content were observed in plants grown on higher levels of fertiliser. The increase of N, P and K levels in the soil resulted in greater total accumulation of these macronutrients. The highest macronutrient contents were K and N. The treatments did not affect neutral detergent fibre (NDF), acid detergent fibre (ADF) and C/N ratio of plant. N. physalodes had low C/N ratio, low NDF and ADF levels, and great nutrient accumulation, suggesting that this plant is quickly decomposed, providing a rapid cycling of nutrients.

Nicandra physalodes belongs to the Solanaceae family that introduce from Peru as an ornamental plant for long ago. This species was naturalized in Java, particularly in Dieng Plateau Central Java and Malang East Java. Furthermore, N. physalodes has been identified as a host of tomato severe rugose virus (ToSRV) in Brazil and as an invasive species in Indonesia. Botanical information and ecological data of this species are still limited knowns, although it has long been discovered in Java. Therefore, the study aims to update the morphological data and range distribution of N. physalodes in West Java. Samples were conducted from vegetable gardens in Pangkalan Village, Ciwidey, Bandung West Java. Morphology data were observed based on living material collected in the field and identified using Flora of Java Book. The distribution data were obtained using a field survey, herbarium observations, and a literature review. Morphologically, the specimens collected from Ciwidey weresimilar to the description in Flora of Java. Seed morphology and stomata data were added to the morphological description of N. physalodes. New distribution in Ciwidey add extends the range of this species outside of its origin area in Java.

Para a adoção de estratégias de manejo de plantas daninhas torna-se imprescindível o conhecimento dos períodos de interferência entre a comunidade infestante e a cultura de interesse econômico. Nesta pesquisa objetivou-se avaliar os efeitos da matocompetição na implantação da pastagem de Panicum maximum BRS Tamani e na rebrotação desta após o corte. Dois ensaios foram conduzidos em blocos ao acaso, com quatro repetições. No primeiro ensaio, a forrageira foi mantida em convivência com as plantas daninhas pelos períodos de 0, 7, 14, 21, 28, 35, 42, 49, 56 e 63 dias após a emergência (DAE) da pastagem, e no segundo ensaio, a forrageira foi mantida sem a convivência das plantas daninhas pelos mesmos períodos até o corte da forrageira, aos 63 DAE. As parcelas foram mantidas livres da convivência de plantas daninhas por capinas manuais, conforme tratamento. A matocompetição se estabeleceu logo após a emergência da forrageira e reduziu o rendimento de forragem. O período crítico de prevenção da interferência de plantas daninhas na pastagem de P. maximum BRS Tamani situou-se entre 1(um) e se estendeu até aos 42 DAE. A interferência de plantas daninhas diminuiu a produção da forragem, bem como a porcentagem de cobertura vegetal, altura do dossel e perfilhamento da forrageira.
