“…The TDM values observed in this study were higher than those found by Aquino et al (2017), while studying the production of clonal plantlets by the cutting method in Conilon coffee. Verdin Filho et al (2014) found a higher TDM in Conilon coffee by using a straight cut at the base of the stem cuttings, which favored the development of the root system and, consequently, of the seedling as a whole.…”

Producing plantlets of Conilon coffee within the specific recommendations and with a high level of quality is fundamental since it is capable of promoting the initial development of the crops. To identify the best protocol to prepare the stem cuttings is fundamental to the process of plantlet production of the species. In this context, this study aimed to evaluate the implications of the type of apex cutting and the length of the remaining apex of stem cuttings to produce plantlets of Conilon coffee (Coffea canephora). To this end, two trials were conducted in the Marilândia Experimental Farm (Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural, Marilândia-ES). The first trial evaluated the types of apex cutting (straight or bevel cut), and the second trial studied the different lengths of the remaining apex (0.5, 1.0, 1.5, 2.0, and 2.5 cm). Characteristics of the vegetative growth and photosynthetic traits of the plantlets of Conilon coffee were evaluated after 120 days of cultivation in a nursery. The biomass accumulation of the plantlets of Conilon coffee produced by stem cutting may be favored by the use of bevel cut on the apex. The length of the remaining apex does not seem to have a expressive effect over the quality or growth of the plantlets, being only possible to observe effects for leaf area and biomass accumulation.

“…Similarly to the variable NL, the DS values for the Conilon coffee seedlings grown on alternative substrates (4.28 to 4.48 mm) can be considered satisfactory (Table 3) when compared with other studies. When studying several types of basal sections and substrates in the growing of clonal seedlings of Conilon coffee, Aquino et al (2017) did not obtain DS values above 3.6 mm. It must be considered that the authors evaluated the seedlings at 100 days after planting, less time than that in this study (120 days).…”

Agricultural wastes as alternative substrates in the production of conilon coffee seedlings

Research related to the use of agricultural residues as alternatives to commercial substrates has become fundamental for reducing the production costs of coffee seedlings. The objective of this study was to evaluate the effect of residues of pepper (Piper nigrum) powder, coffee (Coffea) husk, coconut (Cocos nucifera) fiber and pine (Pinus) bark as alternative substrates in the development of coffee (Coffea canephora) seedlings in tubes. The experiment was carried out at the Demuner Seedling Nursery, in the municipality of São Roque do Canaã, Espírito Santo, Brazil. The experimental design was completely randomized, with six treatments: T0- Bioplant® commercial substrate (control); and from T1 to T5, increasing proportions (%) of pepper powder and decreasing coconut fiber and pine bark (0/20/50, 10/15/45, 20/10/40, 30/5/35 and 40/0/30) and fixed proportions of coffee husk (30%). At 120 days after staking, we evaluated the plant height, number of leaves, stem diameter, shoot dry mass and root dry mass. Any of the substrates containing different proportions of agricultural residues can be used as an alternative to the commercial substrate in the production of Conilon coffee seedlings since most of the growth variables evaluated did not differ from the control. Due to the high availability of pepper powder in the region, we recommended the substrate with 40% pepper powder, 30% coffee husk and 30% pine bark.

“…Neste contexto, garantir suporte inicial as plântulas, possibilitando um local firme para o desenvolvimento radicular e principalmente, favorecer as condições físico-química com as quantidades necessárias é a função principal de um bom substrato (SILVA et al, 2013), sendo sua composição, determinante na fase de 132 formação das mudas (AQUINO et al, 2017). Em vista da disponibilidade de resíduos alternativos para composição de substratos e os desafios para produção de mudas com qualidade a baixo custo, objetivou-se avaliar substratos alternativos para produção de mudas de cerejeiras.…”
