Vegetative propagation of lemon balm on different substrates

Abstract

The production of seedlings by cutting is influenced by several factors, among them the type of substrate. In this context, the objective of this work was to evaluate the effect of different substrates on the vegetative propagation of lemon balm (Lippia alba). The experiment was carried out during the period from August to October 2014, in the municipality of Redenção, Ceará. The experimental design was in randomized blocks, with five treatments: T1 = soil, T2 = soil + bovine manure (2:1, v:v), T3 = soil + earthworm humus (2:1, v:v), T4 = soil + plant organic matter (2:1, v:v), T5 = soil + bovine manure + earthworm humus + plant organic matter (2:1:1:1, v:v:v:v) and five replicates. Apical herbaceous branches were used to produce the cuttings, with the cutting being done in polystyrene trays. After a period of 35 days, the cuttings were removed from the trays and the number of leaves and shoots, length of root and shoot, fresh and dry mass of the cuttings were evaluated. The data obtained were submitted to analysis of variance and, subsequently, when significant by F test, to the Scott-Knott test at 5% probability for comparison of means. It was observed that all the evaluated variables had a significant influence of the types of substrates used, with emphasis on treatments soil + bovine manure + earthworm humus + plant organic matter and soil + bovine manure, in which the cuttings showed better responses. Since these substrates are efficient, they are indicated for the production of L. alba seedlings by cutting.

Evaluation of Different Organic Fertilizers in the Sustainable Cultive of Coriander

“…demand in relation to nutrient availability in the soil, thus avoiding immobilization or mineralization of them. The development of strategies related mainly to the use of resources derived from the agricultural property itself, allows the recycling of by-products, reducing expenses and reducing dependence on non-renewable resources (Costa et al, 2017).…”

“…In this perspective, 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;Saldaña et al, 2014). 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.…”

“…In view of the environmental problems caused by the excessive and indiscriminate use of chemical fertilizers, alternatives aimed to improve the production chain in a more sustainable way, through the use of organic compounds and biosolid wastes, are being studied (COSTA et al, 2017). The organic materials most commonly used by farmers are organic compounds, which are fertilizers from the composting process, which can promote improvements in the chemical, physical and biological properties of the soil (BRANDANI et al, 2019;LARNEY;ANGERS, 2012).…”
