Abstract

Tillage systems are components of broad agricultural practices that affect soil properties and soil health. These changes include soil respiration, density, moisture, and pH. Conservation agriculture practices have the potential to improve soil health by reducing tillage. In agricultural production, there can be numerous approaches to achieving consistently high yields annually; however, this study specifically looked at conventional tillage and conservation agriculture systems. This study aimed to determine soil fauna biodiversity and soil health under conservation agriculture (CA) and conventional tillage (CT) management practices of vegetable production in Cambodia. Five CA and five CT plots were selected and included in this study. Fifty soil samples were collected from CA and CT plots for soil fauna measurement, and in-situ tests were made using Biofunctool© for soil health assessment. The results showed that the abundance of soil fauna and aggregation stability were greater in CA than in CT. Soil fauna biodiversity enhancement may provide better soil health for soil improvement by adapting farming management practices.

Abstract

Tebat Pulau Village is a formerly protected forest area that has become a community social forest processed and planted with robusta coffee. Robusta coffee from the Tebat Pulau Village Farmers Group is of good quality because it is in great demand and attracts the attention of large buyers. However, the quality profile, the roasted coffee criteria, and the preferred quality of the brewed coffee are not yet known. Therefore, this research was conducted to determine the quality profile of rice coffee, the physical and chemical characteristics of ground coffee and the brewing quality of robusta coffee during roasting time. The experimental design used was Completely Randomized Design with one factor. The factor tested was roasting time (P), which consisted of 4 treatment levels, namely P1:10 minutes, P 2:11 minutes, P3:12 minutes, P4:13 minutes with roaster temperature 200°C and bean temperature 107°C. The research was carried out with three repetitions to produce 12 experimental units. The results showed that the coffee from the Tebat Pulau Village Farmer Group had quite large coffee beans with a water content value of 9.00%, had quite a lot of lanang (peaberry bean) coffee beans, and had a total defect value of 13.83. Ground coffee samples with a long roasting time significantly affected water content, color, ash content, coffee essence, and caffeine content. The best-brewed coffee quality was obtained at 12 minutes of roasting time with a final score of 8.50, included in the "fine" category.

Abstract

Coffee is a leading commodity in Bengkulu Province, whose production still needs to be improved. One of the supporting factors for coffee fruit production is the existence of a good soil arthropod ecosystem. Information regarding the diversity of soil arthropods can be considered in evaluating coffee plants' health. This research aims to obtain initial data on the diversity of soil arthropods and their role in central coffee plantations in Tebat Pulau Village, Bermani Ulu District, Rejang Lebong Regency. This research began with taking soil samples from productive coffee plantations. The type of coffee plant sampled was robusta coffee at an altitude of 900, 1000, and 1100 meters above sea level. Next, the soil taken is placed in the bottom funnel. Arthropods obtained from the Berlesse funnel were identified and counted. The results of counting arthropods are used to calculate diversity, dominance, and evenness index numbers. The results show moderate variability in the three types of elevation: low dominance, high evenness. Research also shows that the highest number of arthropods is found at an altitude of 900 m, and the most common type is acarina.

Abstract

In this study, we aimed to investigate which components of cassava (Manihot esculenta Crantz) would be associated with the cassava tuber weight when infected with the Sri Lankan Cassava Mosaic Virus (SLCMV). We conducted multiple regressions to find associations between other cassava elements and tuber weights. This study was carried out in the Rukhak Kiri district in Battambang Province, located in northwestern Cambodia, in March 2019. We assessed two major varieties used in the region, namely, KU 50 and Rayong 7, using 90 samples—60 samples of KU 50 and 30 samples of Rayong 7. The results showed that the tuber weight of KU 50 was heavier than that of Rayong 7. In addition, the biomass of the stem, that is, the weight of all branches and leaves, were the sole strong factors associated with tuber weight for both KU 50 and Rayong 7. Moreover, as the tuber number declined, the tuber weight declined rapidly for Rayong 7. Overall, we concluded that SLCMV infection affects the biomass weight of cassava.

Abstract

Sungai Suci is a part of Bengkulu that is 400 meters above sea level. Sungai Suci is located in a coral coastal area with three ecosystems: the bamboo ecosystem and the sea pine ecosystem; soil arthropods are among the animals that inhabit those two environments. This study aims to look into the variety of soil arthropods in the ecosystem of Sungai Suci. Sampling bamboo and sea pine ecosystems was done by taking soil from the root areas of bamboo and sea pine. For each ecosystem, five soil samples are taken randomly as replication. The soil was placed in a smaller funnel and left for two weeks at room temperature 24ºC, and 12 hours of irradiation. Soil arthropods obtained from the three ecosystems were identified, and their numbers were recorded. The most common type of arthropod found in the three ecosystems was acarina. The study results showed that the diversity values of the bamboo and sea pine ecosystems, respectively, were 1.44 and 0.49; and. Dominance values for the bamboo and sea pine ecosystems, respectively, are 0.38 and 0.82. The evenness values of the bamboo and sea pine, respectively, are 0.56 and 0.18.
