ABSTRACT The modification of water management in the Conilon coffee (Coffea canephora) crop is a possible strategy to improve nutritional management efficiency and ensure better use of the genotypes for regions of transitional altitude. The objective of this study was to evaluate the nutritional characteristics of 27 genotypes of C. canephora and submit them to two water management schemes in soil. The goal was to find evidence of higher leaf contents, exports, and nutrient recycling potential in the productive branches of various genotypes. The experiment was carried out in a randomized block design with three replications in a split-plot scheme. The treatment consisted of 27 genotypes of C. canephora and two water management schemes in soil (“Irrigated” and “Rainfed”). Nutritional content in leaves, exported by fruits, and pruned (leaves and stem of plagiotropic branches) recyclable contents were evaluated for nitrogen, phosphorus, potassium, calcium, and magnesium. Variations were observed among genotypes for all the parameters evaluated in both water management in soil. However, significant homogeneous groups were formed among the genotypes in the irrigated management. Furthermore, the genotypes showed distinct nutritional characteristics in response to water management in the soil. Genotypes 108 and 302 had higher nutritional content and were exported by fruits, regardless of soil water management.

It is important to consider the nutritional demand among genotypes of the same species to achieve high yields. Thus, the objective of this study was to determine the concentration of nutrients in leaves, flowers, grains, and fruit straw in conilon coffee genotypes. The experiment was carried out under a randomized block design, with three replications and the evaluation of nine genotypes. Leaf collections were carried out every three months, from August 2019 to May 2020. Flowers were collected at flowering in July 2019 and fruits in June 2020, upon complete maturation of the genotypes. The materials were dried in an oven and sent for laboratory analysis to determine the nutritional content. Data were subjected to analysis of variance followed by a comparison of means and estimates of genetic parameters and clustering using the hierarchical method (UPGMA). The nutrients found in the highest concentrations in the evaluated plant organs were N and K for macronutrients and Fe for micronutrients. For the leaves, the concentrations of the main nutrients were high in the first and reduced in the last evaluated periods, possibly due to mobilization to the fruits. Considering all the plant tissues evaluated, the order of concentration of macronutrients and micronutrients was N > K > Ca > P = Mg = S and Fe > B > Mn > Cu > Zn, respectively. For a nutritional diagnosis, it is important to take comparisons of the genetic diversity and evaluation periods into consideration.

Robusta coffee plant propagation is recommended to be performed by vegetative methods, one of which is cuttings. Among plant organs that can be used for cuttings is the stem. The research objective was to determine which stem segment from cuttings was able to provide the best root and leaf growth. The layout study used a completely randomized block design (RBD) with an experimental treatment consisting of five stem segments, namely (1) the first stem segment from the upper shoot (A); (2) the second stem segment from the upper shoot (B); (3) the third stem segment from the upper shoot (C); (4) the fourth stem segment from the upper shoot (D); and (5) the fifth stem segment from the upper shoot (E); each treatment had five replications. Data analysis was performed statistically with analysis of variance (ANOVA) and Tukey's HSD (honestly significant difference) test with a significance level of P < 0.05. Robusta coffee cuttings stems from the second stem segment from the upper shoot were able to provide the optimal root growth (root length) and shoot growth (leaf sprout height and leaf sprout growth rate). Leaf sprout number derived from the cuttings was not affected by the stem segment.

ABSTRACT: The objective of this research was to quantify the genetic divergence of potential Coffea canephora parents, with the goal of developing progenies that associate the best traits of the Conilon and Robusta botanical varieties for hybrid vigor expression. Thus, 10 morphological and productive characteristics of 130 clones of Conilon and Robusta botanical varieties and their intervarietal hybrids were evaluated over 2 years. The experiment was conducted in a randomized block design with four replicates of four plants per plot. For selection of parents, the main component analysis was used to associate values with reference points obtained from the average of each botanical variety. The first two principal components allowed for the separation of the botanical varieties representing the variability contained in the original data with 76% for the first year and 69% for the second year. Although, the genotype × years interaction had significant effects, there were minor differences in the grouping from one year to the next, which is associated with the higher repeatability estimates observed in this study. It was observed that crosses with the 16-1-81I, 9-1-82L, and 13-1-61I parents of the botanical variety Robusta and the 167I, 890E, and 130I parents of the Conilon botanical variety presented greater potential for obtaining selection gains.

The study aimed to determine the effect of organic planting media and the position of seed planting on the growth of Robusta coffee seedlings. The study is conducted at the Tabanan Agrotechnology Study Program, Tabanan University, which conducted from July 2019 to September 2019. The treatments are arranged in factorial in a randomized block design (RBD). Two treatments examined in this study were the doses of organic matter in the growing media (0g, 150 g, 300 g, 450 g) and seed position (prone position, upside down, tilted position). The results show that the interaction between organic planting media (soil + coffee leaf compost) and seed planting position did not significantly affect all coffee seedlings growth variables. The dose of organic compost in the growing media has a very significant effect on all growth variables except when growing and the percentage of growth. The dosing of 450 g organic matter gave the highest root fresh weight, fresh stem weight and fresh leaf weight (1.00 g, 2.97 g and 8.64 g respectively) and oven dry weight for the three variables (respectively 0.39 g, 0.55 g and 1.36 g). Seed planting position has no significant effect on all observed variables, but there is The tendency of planting position with the prone on average gives better growth compared to other positions.

Drought is one of the limiting factors for the growth and yield of coffee plants. Drought due to long dry season has caused many losses for coffee plantations. This study aimed to evaluate the response of four Robusta coffee clones to drought stress at seedling stage and determine the best clone with high tolerance to drought. The study was conducted in Indonesian Coffee and Cocoa Reseach Institute (ICCRI) Jember, East Java in November 2018–Mei 2019. The experimental design used a Randomized Block Design (RCBD) with two factors. The first factor has consisted of five levels drought through providing volume watering based coefficient and evaporation value of free water surface (Eo), namely: 0.5 Eo; 1.0 Eo; 1.5 Eo; 2.0 Eo; 2.5 Eo (control). The second factor has consisted of four Robusta coffee clones, namely: BP 409 (drought tolerant clone); BP 308; BP 939 and BP 358 (vulnerable to drought stres). The result showed that reduction in the volume of watering from 2.5 Eo until 0.5 Eo causes drought, reduce coffee growth linearly. Clone BP 409 and BP 939 had better tolerance of drought stress compared with BP 308 and BP 358. The anatomical adaptation of leaves of BP 409 to drought stress was by thickening of wax layer and palisade tissue. BP 939 thickened its leaves due to drought stress as a mechanism of adaptation to such condition.

The objective of this study was to evaluate the influence of five levels of N and two regrowth intervals on the structural, productive, and nutritional characteristics of Tifton 85 grass (Cynodon spp). The experiment was conducted in a hay production field at the State University of West Paraná, planted in 2004 with Cynodon spp. cv. Tifton 85. The experiment was established in a randomized block design with factorial treatments of five N fertilization amounts (0, 25, 50, 75 and 100 kg ha-1 cut-1) applied as urea after each cut, and two regrowth intervals (28 and 35 d), with four replicates. N application promoted changes in plant structure, such as increased canopy height, stem length, leaf elongation rate, and dry mass (DM) production. The greatest N use efficiency, considering the four harvests, occurred in the plot with 25 kg N ha-1 cut-1 at the 35-d interval, with a production of 13.79 kg DM kg-1 of N applied. A nutritional analysis indicated that 100 kg ha-1 of N cut-1 promoted higher crude protein (CP) at 28 d, with the highest concentration observed in the fourth cut (208.2 g kg-1 DM) and the lowest in the second cut (140.12 g kg-1 DM). The content average in the four cuts for CP and LIG at 28 days of regrowth was 175.85 and 104.33 kg-1 g MS and at 35 days of regrowth interval was of 164.45 and 118.65 g kg-1 DM, respectively. No differences were found between regrowth intervals in the contents of mineral matter and acid detergent fiber (ADF). Environmental factors including the wide variation in precipitation (greater than 200 mm between the peak in December 2010 and the lowest in March 2011) greatly influenced Tifton 85 grass production, affecting DM and the nutritional value of the forage in each cut.

Abstract. Asyiah IN, Mudakir I, Hoesain M, Pradana AP, Djunaidy A, Sari RF. 2020. Consortium of endophytic bacteria and rhizobacteria effectively suppresses the population of Pratylenchus coffeae and promotes the growth of Robusta coffee. Biodiversitas 21: 4702-4708. Pratylenchus coffeae as the coffee-parasitic nematode can cause a yield loss from 28.7% to 78.4% on Robusta coffee (Coffea canephora A. Froehner). Environmentally friendly and sustainable efforts can be made to control this nematode by applying the antagonistic agents from the bacterial group. The application of antagonistic agents in a consortium has a better effectivity than a single application. This study was aimed to identify the effectivity of the consortium of endophytic bacteria and rhizobacteria formulated on a cost-effective molasse medium against the P. coffeae population and growth of Robusta coffee in a greenhouse. A total of nine bacterial isolates of genus Bacillus and Pseudomonas were used during experiment. The formulation was prepared by mixing the bacterial suspension and 2% molasses with a ratio of 1:1 (v/v). The greenhouse assay was performed following the completely randomized block design pattern with five treatments and five replications. Robusta coffee plant clone BP 936 was treated with a 10 mL (109 CFU mL-1) bacterial consortium mixture while control was treated with 10 mL sterilized water. Each plant was inoculated with P. coffeae 50 J2 after a week of bacterial consortium application. The result showed that all bacterial consortiums were effective in suppressing the population of P. coffeae in soil and root of Robusta coffee. All consortiums gave a better result than control in suppressing the population of P. coffeae. The best suppression of nematodes was shown by the Cst 02 consortium with the suppression value of 62.5% in the root and 76.1% in the coffee plant rhizosphere. The application of bacterial consortium increases the plant height (28.02-44.51%), number of leaves (127.27-168.18%), and leaf area (278.8-425.57%). In this study, suppression of P. coffeae population by bacterial consortium showed a positive correlation with plant growth. This study presents the information of endophytic bacteria and rhizobacteria consortium from Bacillus and Pseudomonas group that is effective in suppressing the population P. coffeae and improves the growth of Robusta coffee.
