Evaluation of Different Organic Fertilizers in the Sustainable Cultive of Coriander

Abstract

The excessive use of agrochemicals in agriculture has been causing irreversible environmental impacts, from this point of view, organic farming appears as an economically viable alternative to minimize these impacts. So, the objective of this work was to evaluate the effect of different types organic fertilizers in the development and production of coriander harvested at different epochs. The experiment was conducted during the period from August to October 2016, in an area of the experimental farm of University of International Integration of Afro-Brazilian Lusophony. The experimental design was a randomized complete block design, in a 5 × 4 factorial scheme, consisting of five organic fertilizers and four harvesting epochs (28, 35, 42 and 49 days after planting-DAP) and five blocks. The variables stem diameter, plant height, root size, number of leaves, leaf length and productivity were evaluated. All the analyzed variables responded significantly by the F test, either for the qualitative factor, fertilizer sources, or the quantitative, epochs of evaluation. Regarding the cultivation epochs, when the first evaluation period (28 DAP) was compared with the last (49 DAP), it was verified that the variables presented linear responses over time, with increases of 34.4% for height , 29.5% for stem diameter, 37.07% for root length and 64.44% for production. In relation to the fertilizer sources, in general, the cattle manure provided a greater growth and production of the coriander plants, being therefore the most suitable for the cultivation.

Effect of Fertilization and Foliar Applicaion Treatments on Coriander Plant (Coriandrum sativum L.)

“…Generally, the treatments sequence from top to less was the ( CP) > (FYM). The present results agree with those obtained by; Abdou et al, (2019) and Da Costa et al, (2019). NPK, Bio-fertilizer and Foliar applications effect.…”

“…Organic matter, bovine manure and earthworm humus appear as important components in the formulation of organic fertilizers, because when mixed with the soil, they contribute with physical and chemical attributes, improving the soil structure and providing the necessary nutrients to the plant development (Costa et al, 2017). The use of these byproducts ends up reducing the cost of production of the horticulturists, providing an increase in the production of this important crop and linked to that, enable a more sustainable agricultural production (Da Costa et al, 2019).…”

Use of cassava wastewater in Capsicum chinense production

“…Concerning the 2006 agricultural census, the highest pepper yields were obtained in properties fertilized with mineral fertilizers (7,238 t) and with the joint use of mineral and organic fertilizers (7,108 t), followed by only organic fertilizers (2,977 t) and agricultural units that did not use fertilization (1,360 t) (IBGE 2006). Costa et al (2019) highlighted the importance of using resources derived from the agricultural property itself to meet the needs of producers, promoting the recycling of by-products and reduction of costs with commercial inputs. In this context, the liquid waste from the cassava flour production may be an important source of organic fertilization.…”
