“…Cuttings were made from the collected stems, sectioning them in parts of nearly 4 cm of length, using straight cutting on the base and bevel cutting on the apex, and leaving a pair of leaves per cutting with nearly one third of their original area. The cuttings were made following the current recommendation for asexual propagation for plants of Conilon coffee (Ferrão et al, 2012;Verdin Filho, 2014).…”

Coffee husk is a residue produced during the fruit processing and it is an excellent source of organic matter. It is an interesting alternative that can be used in the formation of the substrate to plantlet production, but the proportion to be recommended is still unknown. In this context, this experiment was conducted with the objective to study the growth, quality and gas exchange rates of clonal plantlets of Conilon coffee produced using plastic tubes, filled with substrate composed of different proportions of coffee husk to partially replace the commercial substrate. The experiment was conducted in a nursery, following a 3×6 factorial scheme in a completely randomized design; studying three genotypes of Conilon coffee and six proportions of coffee husk in the composition o f the substrate for plantlets production from 0% to 100%. Overall, the results showed gains in growth and quality of the plantlets when coffee husk was added in the substrate but decrease in gas exchanges, especially over the net carbon assimilation. Considering the growth and quality, most detrimental effects started being observed with proportions above 38%. Different patterns of response were observed among genotypes, which must be taken into consideration for further researches to help define safety levels and a possible recommendation to use coffee husk in the substrate.

Influence of nitrogen fertilization in mother plants on the growth and quality of clonal seedlings of Coffea canephora ‘Robusta’ plants

The nutritional management of the coffee clonal garden influences the production and physiological quality and seedlings production of vegetative propagules. Thus, this study aimed to analyze the seedlings’ production from clonal cuttings taken from Coffea canephora mother plants grown with increasing nitrogen mineral doses. The cuttings were taken from C. canephora var. botany Robusta, from the Embrapa Genetic Improvement Program of Rondônia. The mother plants received nitrogen fertilizer at different doses: 0 (Control); 50; 100; 150; 200; 250 and 300 kg of N per hectare divided into 4 applications, during 150 days of orthotropic stems growth (shoots). The following parameters were evaluated: Dry mass of cuttings, nutritional content of cuttings, and seedlings production, with growth analysis at 0, 48, 61, 80, 101, 122, 143, and 164 days after staking (DAS) and analysis of vegetative characteristics at 122 DAS. The nitrogen fertilization in the mother plant resulted in the variation of macronutrient accumulation in cuttings, but the order K> N> Ca> P> Mg> S was maintained, regardless of N dose. In addition, a positive correlation between nitrogen doses and dry matter accumulation, as well as the physiological quality of seedlings was identified.

The objective of this work was to evaluate the production of cuttings of Coffea canephora genotypes, in a new system for training mother plants called “vertical clonal garden”. The proposed new system consists of training coffee plants with only one shoot and without bending the main shoot, so that the secondary orthotropic shoots, from which the clonal cuttings will be taken, are formed across the length of the stem in the vertical direction. The capacity for the production of cuttings of ten hybrid genotypes of coffee plants was evaluated over ten production cycles. The 'BRS 2314', 'BRS 3213', and 'BRS 3210' genotypes showed cutting production per cut of 425,000 cuttings per hectare, considered above the obtained average. The 'BRS 3193', 'BRS 2336', 'BRS 3220', and 'BRS 3137' genotypes were the least productive. Coffee plants trained in the “vertical clonal garden” system can produce about 425,000 cuttings per hectare per harvest period or about 1.275 million cuttings per hectare per year, over three harvest periods, with a greater ease in crop management and treatments.
