Abstract

The main problem faced in the utilization of Red Yellow Podsolic soil (RYP) is the low nutrient content and poor physical and chemical properties of the soil. Problems with the chemical properties of RYP soil include acidic soil pH, low organic C content, low available P, low CEC and low interchangeable bases (K, Ca, Mg, Na). This study aims to improve some of the chemical properties of PMK soil with the application of compost as an ameliorant and its effect on the growth and yield of caisim (Brassica juncea L.) as an indicator plant. The study used a single factor Completely Randomized Design (CRD) with 5 treatments consisting of no compost (K0), compost 5 tons/ha (K5), compost 10 tons/ha (K10), compost 15 tons/ha (K15) and compost 20 tons/ha (K20). The results showed that the application of compost at a dose of 20 tons/ha (K20) was able to increase the pH, C-Organic, CEC, available of P and exch-Ca, exch-Mg, exch-K and exch-Na of RYP soil and increase the production of caisim.

Abstract

South Lamaknen District is the center of coffee production in Belu Regency. Coffee production is influenced by external and internal factors, H. vastatrix attacks are among the main external factors that limit coffee production in this district. Data information related to leaf rust disease in Belu district does not yet exist. Data on the distribution and severity of coffee leaf rust disease in this district do not yet exist. Such data is needed to determine appropriate control strategies to improve coffee production. The study aimed to obtain data on the severity of coffee leaf rust disease in smallholder coffee plantations in Belu Regency. The research method used was purposive random sampling (PRS) in the Belu people's coffee center in Lakmaras and Henes Villages, South Lamaknen District, with a geographical location between 9 ْ0.9' 26.61"N and 125 ْ 09' 50" LS, at an altitude between 866,7 – 1007,7 m above sea level. This study shows that coffee leaf rust disease is spread in geographical locations 9 ْ 0.9' 26.61"N and 125 ْ 09' 50" LS. The highest intensity of coffee leaf rust disease occurred in Henes village, which was 39%, while Lakmaras village was 22%. External factors affecting the incidence and severity of disease are temperature and use distance between coffee plants.

Abstract

This study aims to determine the effect of soaking duration of shallot bulbs using Local Microorganisms (MOL) on seed viability and vigor during the early growth phase. The research was conducted at the Agrotechnology Laboratory, Unit Stiper Petra Baliem Wamena, from April to August 2018 using a Completely Randomized Block Design (CRBD) with six MOL soaking duration treatments: 0 minutes (control), 30 minutes, 60 minutes, 90 minutes, 120 minutes, and 150 minutes, each repeated four times. The observed parameters included germination percentage, maximum growth potential, growth rate, plant height, and number of leaves at 14 days after planting (DAP). The results showed that MOL soaking treatments influenced the viability and vigor of shallot seeds. The highest germination percentage was obtained at the 60-minute treatment (95%), while maximum growth potential was relatively uniform across almost all treatments (100%). The highest growth rate was observed at the 150-minute soaking duration (85.57%), whereas the control treatment produced the lowest value (57.23%). Early vegetative growth also showed the best response at the 60-minute treatment, with plant height reaching 7.50 cm and the number of leaves reaching 10.75 at 14 DAPS.

Abstract

The presence of weed vegetation is one of the main limiting factors in increasing the productivity of paddy fields in the semi-arid region of Kupang Regency. This study aims to identify the species composition and analyse the community structure of weeds in the paddy field agro-ecosystem in Mata Air Village using the Summed Dominance Ratio (SDR) parameter. The study was conducted using a quadrat method with 24 sample plots (0.25 m²) laid out randomly. Data were analysed quantitatively to determine Relative Density (RD), Relative Frequency (RF), and SDR. The results identified three main groups of weeds with varying levels of dominance. Sedges were the most dominant group with the highest SDR value (38.74%), driven by a very high individual density in the field (RD 47.85%). Grasses ranked second (SDR 31.64%), followed by broadleaves with an SDR value of 29.62%. Although they had the lowest dominance, broad-leaved weeds exhibited the most even spatial distribution across the study area (FR 38.89%). The combined dominance of sedges and grasses, which exceeded 70%, indicates that competition for nutrients and space at the study site is heavily influenced by monocotyledonous vegetation. These findings suggest the need for the integration of intensive soil management and appropriate water management as part of an Integrated Weed Management (IWM) strategy in Mata Air Village. Keywords: weeds, vegetation analysis, mata air village, paddy fields, SDR

Abstract

Cocoa productivity is influenced by soil fertility, particularly soil chemical properties that play an important role in nutrient availability for plants. This study aimed to analyze the characteristics of several soil chemical properties in cocoa plantations with different productivity levels in Malaka Regency. The research was conducted in high- and low-productivity cocoa blocks through purposive soil sampling. Laboratory analyses were carried out on several soil chemical parameters, including soil pH, organic C, available N, available P, available K, cation exchange capacity (CEC), and electrical conductivity (EC). The results showed that the high-productivity block had higher levels of organic C, nitrate-N (N-NO₃), available K, and CEC compared to the low-productivity block. Available P content in both blocks was classified as low and was suspected to be a limiting factor for cocoa growth. Soil pH values in both blocks were categorized as neutral and remained suitable for cocoa cultivation. Meanwhile, EC values in the low-productivity block were higher than those in the high-productivity block, indicating greater accumulation of soluble salts in the soil. This condition was supported by the presence of salinity symptoms observed in the field, such as drying and death of cocoa plants in the low-productivity block. Based on the findings, it can be concluded that cocoa blocks with high productivity had relatively better soil chemical properties than low-productivity blocks. Differences in soil chemical properties, particularly organic matter content, available N, available K, CEC, and salinity level, were suspected to influence cocoa productivity in Malaka Regency. Keywords: cocoa, soil chemical properties, productivity, salinity, soil fertility
