Conteúdo:  The conilon coffee tree presents high yield potential, the replacement of soil nutrients usually being by the use of mineral fertilizers. To reduce these fertilizers, the use of organic waste may be an alternative. The objective of this study was to evaluate the effect of organic fertilizer systems on the nutritional status and yield of the conilon coffee tree. On a farm, located in the town of Linhares, Espirito Santo, during the agricultural year of 2009/2010, a trial was set up using a completely randomized block design with a factorial distribution of 2 x 2 x 5 and three replications, the factors being: organic compost (compost 1 and compost 2 ); legumes (the presence and absence of jack beans, sown between the rows of coffee trees); and the proportions of each compost (0; 25; 50; 75 and 100%) as a substitute for the recommended mineral fertilizer. The increase in the proportion of compost 2 was reflected as increases in the P content of the leaves due to the higher concentration of this nutrient in the compost. The increase in compost input increased the S content of the leaves as a response to the increase in soil pH. Maximum values of 61 and 66 sacks ha-1 were obtained with substitutions (mineral source by organic) in the proportion of 40 and 37% for compost 1 and compost 2 respectively. The use of organic-waste composts is an alternative as a partial replacement of mineral fertilizers in the conilon coffee tree, resulting in increases in yield. O cafeeiro conilon apr... Mostrar Tudo

Título:  The intensity of the drying process influencing the germinative potential of seeds of Coffea canephora harvested from genotypes of early maturation.

Conteúdo:  Several physical, chemical, and biological attributes of coffee seeds can be influenced by the drying and storage conditions. To propagate the recommended cultivars using seeds, it is often necessary to grow seedlings from genotypes of different maturation cycles, for which the mature seeds are only available in different moments throughout the year. This study aimed to test the germination of seeds of Coffea canephora Pierre ex A. Froehner from genotypes of early maturation, after being subjected to different periods of natural or artificial drying. For this end, two trials were developed, following split-plot (in time) scheme and completely randomized design, to study the moisture content of seed dried by two different drying process along 27 periods (between 0 and 320 hours), and the germinative potential, based on the germination speed index and proportion of germinated seeds after 30 days, of seeds dried by two drying process and 12 levels of seed moisture (between 50% and 8%). The results show that artificial drying at 35 ˚C removes seed moisture faster than the natural drying at 25 ˚C. Both drying methods can be used for decreasing seed moisture. However, the faster water loss negatively affects the germinative potential of seeds of genotypes of C. canephora of early maturation. The natural drying at 25 ˚C seems to have lesser impacts over the germination process, which may represent a good alternative if the seeds are stored at low levels of moisture. ... Mostrar Tudo
