This research is related to the performance evaluation of twelve Coffea arabica cultivars in Vale do Ribeira Paulista, in order to generate consistent information for the technical recommendation for cultivation in the region. The experiment was set in February 2018, at the Experimental Campus of the São Paulo State University “Júlio de Mesquita Filho” - UNESP in Registro, SP, Brazil, in a spacing of 3.00x0.60 ...
The aim of this study was to determine agronomic characteristics and responses to the coffee leaf rust fungus (Hemileia vastatrix Berk. et Br.) in coffee progenies resistant to the gall nematode Meloidogyne exigua. The experiment was conducted in December 2000 at Ouro Verde Farm (FazendaOuro Verde), located in the municipality of Campos Altos – Minas Gerais (MG). Ten F3:4 progenies were evaluated. They were der...
The cultivate Apoatã 2258 (Coffea canephora) has been used as a rootstock cultivar of Coffea arabica. However, due to the wide availability of genetic resources found in different regions of the country, there is a vast field to be explored in the research of new genotypes to be used as rootstock. The choice of these materials should be based in combination with the graft and adaptation to the ecosystem where i...
The use of grafting in coffee, and give greater tolerance for nematodes, have shown influence on the growth of coffee, so the purpose of this study was to evaluate the growth of different varieties of Coffea arabica L. grafted into Apoatã IAC 2258 (Coffea canephora). The experiment was installed in a greenhouse, using the method of cultivation in nutrient solution. It used a factorial 7 x 3 + 2, and seven culti...
This study evaluated the development of seedlings of Coffea arabica cvs. grafted in Apoatã IAC 2258 (Coffea canephora). The experimental design used was a randomized block with a 7x 3+2 factorial arrangement. Were utilized seven C. arabica cultivars (Obatã IAC 1669-20, Acauã, Oeiras MG 6851, Catucaí Amarelo 2SL, Topázio MG 1190, IBC Palma II and Paraíso MG H 419-1), three kinds of seedlings (grafted, self graft...
The analysis of growth is performed in order to explain the differences in growth of plants. This work had the objective of evaluating the development of C. arabica L. seedlings grafted with C. canephora Pierre ex Froehner. The experiment was performed in a greenhouse at the Federal University of Lavras using nutritive solution. There was used a factorial 7 x 3 + 2, with seven cultivars of C. arabica (Palma II,...
This paper aimed at to evaluate the fruit production in different positions of coffee plagiotropic shoot (Coffea arabica L.), during eight months. Measurements started in October 21 taking five different regions of eight shoots located in the central region of a plant belonging to the cultivar of Rubi MG 1192; located at the Coffee Section from the Federal University of Lavras. The experimental design used was ...
Higher production of coffee plants (Coffea arabica L.), requires abundant and deeper roots, well branched and physiologically active. However, the root grow system is a complex process, which is affected by many factors. Thus, this work aimed at to study the influence of multiple roots in the initial growth of three coffee cultivars considering the presence and absence of mulch on the planting row. The experime...
The objective of this work was to evaluate the productivity and resistance to leaf rust (Hemileia vastatrix Berk. & Br.) of twenty four F4 coffee progenies from crosses between the Icatu and Catimor cultivars. The experiment was carried out in Três Pontas, Minas Gerais State, in a randomized block design with four repetitions and 25 treatments. The Rubi MG 1192 cultivar was used as control. Coffee bea...
Coffee seedlings are frequently lost when left in the nursery after the ideal planting time, although research has shown that they may be recovered when grown in polyethylene bags. The objective of this work was to compare polyethylene bags and tubets as recipients for the recovery of coffee seedlings kept in a nursery for late planting through pruning. The experiment was carried out at the Coffee Sector of UFL...
