In mountain regions due to the high slopes, the coffee harvest is carried out manually, generating higher production costs. An alternative to reducing these costs is to use portable breakers. The objective of this work was to evaluate the efficiency of portable coffee breakers in coffee harvesting. The experiment was carried out in a field of Catucaí Amarelo 24/137, 3.5 years old. In the study, six types of breakers were tested, in addition to an extra treatment, the experiment was delineated in randomized blocks with four replicates. The number of broken coffee, remaining coffee, number of broken branches that fell on the melting cloth, number of primary and secondary branches present in the plants and defoliation were evaluated. The commercial bruising Brudden promoted a greater amount of broken branches fallen in the cloth of derrick. Regarding the defoliation, it was observed that the Brudden melt promoted the highest values, followed by commercial brands AGS Dupla, Nakashi and Sthil WR9. The treatments Sthil WR6 / 2 and WR6, and Sthil associated to the rubber extensors obtained the lowest values of defoliation. Brudden was also the one that promoted the largest amount of broken branches accounted for in the plant. Based on that, results showed that harvest process using portable milling machines has high harvesting efficiency.
Pigs can be used in the formation of coffee seedlings; it gradually provides essential nutrients for the development of plants, in addition to promoting the improvement of the substrate and water retention. It was decided, with this work, to evaluate the use of pig compost in the formation of coffee seedlings. The topics studied were: T1-Witness (absence of organic compound); T2-30% concentration of cattle compost; T3-15% concentration of pig compost; T4-30% concentration of pig compost; T5-45% concentration of pig compost. The five treatments were arranged in a randomized block design, with five replications. The best treatment for plant height and collection diameter was 45% of pig compost. The best results for the total dry matter were obtained with treatments with 30 and 45% of pig compost. The compost based on pig manure at 30% stood out in comparison to the standard cattle manure at 30%, providing higher levels of M, O, P, Mg and micronutrients (B, Cu, Mn, Zn). The use of 30 or 45% of manure-based compost produces coffee seedlings similar to the 30% of cattle manure composting.
Spraying a coffee plantation simultaneously with harvesting ensures that the coffee plants are protected from pests and diseases, which are intensified during this period. In addition to economical operation, the pulverizer adapted to all harvester models promotes greater uniformity in pulverized syrup dispensing since the spray tips are arranged evenly around the plant. Two experiments were carried out in the municipality of Capelinha and Varjão de Minas, MG, comparing the Pulverizer Kit with two volumes of syrup to the Arbus 2000 standard and Arbus 2000 Cerrado, respectively in experiment 2. The experiments were conducted using a randomized block design, with seven and ten replications, respectively, for plots of 20 plants to evaluate the deposition of the syrup in the upper, middle, and lower thirds of the plants. It was concluded that the Sprayer Kit adapted to the coffee harvester is a suitable option for spraying simultaneously to the harvest, using syrup volumes lower than those commonly used in coffee cultivation. The application with Arbus 2,000 had difficulty in reaching the upper third of the coffee tree, whereas this did not occur when the coffee was pulverized using the Spray Kit, regardless of the volume of syrup used.
The soybean stands out in the Brazilian agribusiness and part of this success stems from the development of improved cultivars. One of the requirements for the concession of protection to a given cultivar is that it should be distinct from others cultivars. Potential additional descriptors of soybean have been studied. Thus, the aim of this study was to evaluate the performance of
