Abstract

In general, turfgrass grows well and forms high quality turf under full sun exposure. It is very difficult, however, to grow a warm season turfgrass under shaded condition. Zoysia grass is a popular warm season grass that commonly grow under full sun exposure condition. There are limited information regarding the growth response and turf quality of zoysia grass when grown under shaded condition. This study aims to observe the growth and quality of various zoysia grass local cultivars at different shading intensities and different mowing. This research was carried out using 10 zoysia grass cultivars planted in the rice fields’ vertisol clay with randomized complete block design. The shading used were control, shade-nets with 25% and 65% hole densities. Zoysia grass was fertilized using NPK; 4:1:3 and mowed three times. The results showed that plants without shade, 25% and 65% received on average solar irradiance of 25,141; 12,456 and 3,727 lux. The increase in shade level decreased the shoot fresh weight, dry weight, root dry weight and the plant height. Shading and frequent mowing effected the plant height. Mowing has more effect on plant height in 25% shading than in 65% shading. The increase in shading, in mowed grass showed increased plant height and decreased plant dry weight. Mowing three times can reduce plant height in all shades. The grasses under 25% shading resulted the highest plant dry weight; whereas and shading 65% resulted the lowest. Plant dry weight and uniformity of turf were affected by the cultivars.

Abstract

The problems faced are uneven football field surface, uneven grass growth, many pebbles and boulders, stagnant and muddy during the rainy season and fractures in the soil during the dry season which make the field not of a good standard for use and have an impact on the incidence of injuries to field users. This study aims to improve the quality of grass for football field using quality local grass Cynodon dactylon in order to overcome the problem of bad fields and avoid field’s users injury. The method is through field rehabilitation technology by improving the surface design and soil media profile as well as the use of quality local grass. The rehabilitation technology includes improving the surface of the field to improve drainage by designing a “geger sapi” shape. The assessment of the rehabilitation results used a qualitative approach with a questionnaire survey to the local community of field users. The results of field grass rehabilitation make the quality of grass in the field after rehabilitation better growth by 45%, perception grass quality was very good by 43%, the surface of the field is flatter, no gravel and surface rocks are found so the flooded were not found by 83%. Field conditions with better grass quality also reduce the frequency of injuries incidents of player during competition about 61%. Hence, field grass rejuvenation benefits the environment and public health. This great benefit will increase the comfort and closeness between the local community.

Abstract

Compost is one of organic fertilizers that play an important role in maintaining soil health and supporting sustainable agriculture. Diverse aspects could be developed to increase the quality of compost. This study aims to compare the quality of compost produced by using two different bioactivators, namely aerobic bioactivator RMC (the microbial consortia isolated from composted rice straw, mahogany bark and cassava peels + additional supplement) and fermentative bioactivator (EM4 + molasses) in the composting of the mainly rice straw-based materials. Composting was conducted using a single factor completely randomized design consisting of five levels as follows: C0 (control, rice straw); C1 (rice straw + bioactivator EM4 + molasses); C2 (rice straw + bioactivator RMC + additional supplement); C3 (rice straw + cow dung + bioactivator RMC + additional supplement); C4 (leaf litter + cow dung + bioactivator RMC + additional supplement, as comparison treatment with no rice straw). Among the treatments of C0, C1 and C2, composting the same rice straw material but different bioactivators, C2 showed the highest compost quality and decomposition rate. Among the other three treatments of C2, C3 and C4 composting different materials but using the same bioactivator, C3 showed the highest compost quality, but the three treatments showed the same high decomposition rate. Based on the characteristics of the compost product, including nutrient content, the treatment C3 produced the highest quality, followed by C4 and then C2. Both bioactivators EM4 + molasses and RMC+ additional supplement tended to increase total bacteria, fungi, nitrogen-fixing bacteria and phosphate-solubilizing microbiota in the compost products compared to the control without bioactivator. A set of aerobic bioactivator RMC plus additional supplement serve as one strategy to accelerate the composting process and to enhance the compost quality.

Abstract

Siamese oranges are one of the most widely developed horticultural crops in Indonesia. Arjosari and Ngadirojo are some of the sub-districts that produce Siamese orange in Pacitan Regency. One of the factors that can affect the development of citrus is land quality. This study aims to obtain land quality index data and improvement efforts for developing Siamese orange. Soil samples were taken from 25 land mapping units (LMUs) with 87 sample points. The soil sampling points were determined based on area or sampling density. Data analysis used for soil quality assessment includes correlation, principal component analysis (PCA), minimum data set (MDS), and calculation of climate quality index. The parameters used in this study are bulk density, porosity, moisture content, texture, pH, electrical conductivity (EC), cation exchange capacity (CEC), base saturation, total N, available P, available K, soil organic carbon (SOC), microbial biomass carbon (MBC), evapotranspiration, temperature, and solar radiation. Based on the results of soil quality analysis in the study area, it has a value range of 0.28 to 0.37, including low class, while the climate quality index is 1.39 with moderate class. The land quality index has a very low to low class with a value of 0.39 to 0.51. Intrinsic, extrinsic, and anthropogenic factors can influence soil quality. The study area’s limiting factors for developing Siamese oranges are EC, total N, and available P, which can be improved by making furrow ponds, adding organic fertilizer, using urea fertilizer, and SP36 according to the dosage.

Abstract

Termites function as soil engineers and play a crucial role in the decomposition of organic matter. This study was conducted in the Alas Bromo Educational Forest under pine stands of various age classes. The objective of the research was to investigate the influence of termite activity on soil fertility, as indicated by the levels of soil organic matter (SOM), soil organic carbon (SOC), and soil pH. The method employed involved baiting pinewood stakes placed in polyvinyl chloride pipes (PVC) to assess termite activity, which was evaluated based on the level of damage to the stakes and classified into damage classes. The stakes used were made of pine wood, similar to the species of the overlying stands. This study identified four termite genera in the Alas Bromo area: Macrotermes, Microtermes, Odontotermes, and Schedorhinotermes. The findings revealed significant differences in SOM and SOC across the stake damage classes within each stand. In general, the highest values were observed in soils with the highest levels of termite activity, as reflected in damage class 4. However, soil pH values did not show significant differences across the varying levels of termite activity. These findings highlight that termites, as soil engineers, play a vital role in enhancing soil fertility and hold promising potential for application in the pursuit of sustainable agriculture.

Abstract

Bagasse, one of the largest agricultural wastes with suboptimal utilization, could improve Entisols in the tropics by enhancing soil fertility and crop productivity. This study aimed to determine the changes in humic substances and nutrient levels in Entisols and their effects on shallot yield. The study was designed using a completely randomized design, consisting of four treatments of organic matter combinations with NPK fertilizer, four single organic matter treatments, one standard NPK fertilizer dose, and one control. Each was replicated three times. The results showed that using bagasse improved soil conditions by increasing C content and nutrient levels in the soil, enhancing nutrient absorption by plants, and consequently boosting crop yields. The biochar + bagasse compost (2:4) (bio-compost) + NPK resulted in high soil organic C, humic acid, fulvic acid, nutrient availability, and plant nutrient levels, which were comparable to the manure treatment, and significantly increased shallot yield in Entisols. The findings of this study could support the development of nutrient management strategies utilizing bagasse as a potential soil amendment for Entisols.
