“…The estimative of genetic parameters shows the existence of considerable variation between genotypes for both systems. Genotypic differences causing expressions of different agronomic traits in C. arabica have been widely reported, such as for biometry of reproductive branches (Rodrigues et al, 2014a), nutritional parameters (Martinez et al, 2011;Moura et al, 2015;Martins et al, 2015;Rodrigues et al, 2015), resistance of plant diseases (Sera et al, 2010;Del Grossi et al, 2013;Rodrigues et al, 2014b;Shigueoka et al, 2014), drought tolerance (DaMatta, 2004;Nardini et al, 2014), and crop yield (Carvalho et al, 2012;Rodrigues et al, 2014c).…”

The use of supplementary irrigation to sustain the plantation during moments of severe water stress or moments of high water demand is becoming almost a norm to keep sustainable crops, especially due to the climate changes and the high frequency in which climate extremes are occurring lately. The objective of this study was to evaluate the agronomic performance and expression of genetic variability among genotypes of Coffea arabica L. cultivated in farming systems with different levels of water supply, focusing on rainfed or supplementary irrigated systems. The experiment was developed in competition field, testing 8 genotypes of C. arabica L. in rainfed or supplementary irrigated systems. The growth and production were evaluated during 2 consecutive cycles (2014-2015 and 2015-2016). Among the growth gains, it was observed large gains in coffee yield, but the magnitude of the gains varied among genotypes. For crop yield, for example, Paraíso MG/H 419-1 presented 136% gain, while Oeiras MG-6851 was capable of yielding as much more coffee in rainfed conditions than in irrigated system. The expression of variability for some agronomic traits (such as coffee yield, canopy size, growth rate, and number of new buds) may be intensified by the supplementary water supply, which promotes gains in production and growth, increases the magnitude of variation among genotypes and allows to identify different patterns for selection, which may not be observed in the rainfed systems.

<em>Coffee "Sidodadi" is the Robusta coffee clone, selected by farmers, widely developed in the Bengkulu region. The clones are distributed at different altitudes, i.e. 600, 900, and 1,200 m asl and presumably have different phenotyphic expression due to different growth environment. This study aimed to determine the influence of altitudes on the phenotypic expression of coffee "Sidodadi". The study was conducted at (1) 600 m asl (Sukarami subdistrict, Bermani Ulu district, Curup Regency), (2) 900 m asl (Airsempiang subdistrict, Kabawetan district, Kapahiang Regency), and (3) 1,200 m asl (Airles subdistrict, Muara Kemumuh District, Kapahiang Regency), from January 2014 to October 2015 with a survey method. A total of 5 trees were randomly assigned to each experimental unit and each was repeated 5 times. Phenotypic characters observed including vegetative morphology and yield components (data obtained using the difference test of two average t-Students on the 5% level), caffeine content, and cupping-test score. The sample of coffee beans used was 500 g with a water content of 10%–10.9% taken at three different altitudes. The results showed a significant effect of altitude on vegetative growth and yield components of "Sidodadi" Robusta coffee. Altitude of 1.200 m asl produces vegetative, generative, and higher-yielding coffee yields, but with lower caffeine content than those grown at 600 and 900 m asl. Meanwhile, the best flavor quality with a score of 85.25 is indicated by "Sidodadi" Robusta coffee grown at an altitude of 900 m asl which delivered high body, long aftertaste, dark chocolate aroma, and caramelly flavor.</em>

“…The initial development of perennial crops, such as coffee (Coffea canephora), is influenced by several climatic and nutritional factors, as well as those related to the quality of the seedlings used (VALLONE et al, 2010a). The quality of the seedlings has a direct influence on the success of coffee crop formation, which must have vigorous development and a well-formed root system (MARTINS et al, 2015). Therefore, all precautions should be taken to ensure the conditions favor the roots development and the balance between the root system and the aboveground part (OLIVEIRA; OLIVEIRA; MOURA, 2012).…”

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

et al. 2020

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.
