Abstract

Phytotoxicity of soil aluminum (Al), both directly to the plant growth as well as indirectly through the increase of soil potential acidity, is closely related to the occurrence of various soil soluble-Al species. Amongst them, Al3+ and monomeric-Al species are the primary causes of Al phytotoxicity in soils with high Al content. This study was aimed to evaluate the effects of soil amelioration with dolomite and base-activated lignite (BAL) on changes in soluble-Al species and other soil chemical properties, and vegetative growth of soybean (Glycine max Merr) on Ultisol of Jasinga (Al-dd 16,03 cmol(+)/kg). A green house experiment was conducted by applying a Completely Randomized Design with dolomite and BAL amelioration as the treatments, each with three levels of repectively 0, 1, 1,5 x exchangeable-Al and 0, 2,5, 5 tons BAL ha-1, and three replications. The ameliorants were incubated at field capacity of soil moisture content for one week before planting soybean for one month. Soil soluble-Al speciation was carried out using colorimetric aluminon method to determine concentrations of total soluble-Al, monomeric-Al, and polymeric-Al species. Monomeric-Al were further speciated into inorganic monomeric-Al and organic monomeric-Al species. The results revealed that only dolomite amelioration that significantly increased soil pH-H2O, pH-KCl, Ca- dd, Na-dd, and decreased exchangeable-Al concentration, except for those of all soluble-Al species that only showed a decreasing trend. Soil exchangeable-Al that was negatively and significantly correlated with soybean measure parameters were plant height, root length, total roots and shoots wet and dry weights, as well as Ca concentration. These results indicated that soil Al phytotoxicity evaluation could be relied on the result of routine analysis on soil exchangeable-Al concentration. Keywords: exchangeable-Al, inorganic monomeric-Al, organic monomeric-Al, polymeric-Al

Abstract

Cultivating red onion on a Vertisol during rainny season could face to physical and chemical problems from the soil. Application of biochar and mycorrhiza can improve soil quality both physical and chemical properties of Vertisol. The objective of this study was to investigate the effect of rice husk biochar and arbuscular mycorrhizal fungus (AMF) on growth and yield of red onion grown on a vertisol. The research was carried out at the Agrotechnology Research Station, University of Trunojoyo Madura from December 2018 to February 2019. The experiments were arranged on Split Plot Design (SPD) with the main plots were the biochar treatments and the sub plots were AMF applications. Two rates of biochar applications namely B0 (no biochar) and B1 (10 ton/ha), and four rates of AMF applications involving M0 (no mycorrhiza), M1 (2.5 g/plant), M2 (5 g/plant) and M3 (10 g/plant), were employed. No P fertilizer was applied on three AMF treatments (M1, M2, and M3). There were 8 combination treatments, and each treatment was replicated four times to end up in 32 experimental units. The results showed that there was no interaction between biochar and AMF treatments on all observed parameters. Biochar increased the number of leaves at 4 and 6 WAP (week after planting), the number of roots, and the weight of fresh tubers, and dry tubers that were suitable for storage. Mycorrhizal (AMF) application significantly influenced the number of leaves at 2 and 6 WAP, number of roots, wet weight of tubers, dry weight of tubers, and percentage of AMF root colonization. The application of rice husk biochar and AMF increased tuber yields respectively up to 17.21% and 19.58% compared to that of control.

Abstract

Sandy clay loam soil in Bangkalan is a soil with a low content of nutrients, organic matter, bases, and cation exchange capacity (CEC), which inhibits the growth of maize plants. In addition, the nature of the soil causes the fertilizer to become more soluble, and the absorption of nutrients, especially potassium, is low. One of the efforts to increase potassium uptake in sandy loam soils is applying biochar and acid-activated bentonite. This study aimed to examine the effect of adding biochar and acid-activated bentonite to the nutrient uptake of maize plants in the sandy soil of Bangkalan. Biochar was prepared from maize cobs by the Kon-Tiki method; bentonite was activated by physical (200 oC) and chemical (1N H2SO4) methods. The greenhouse experiment was carried out using a completely randomized design with biochar (B) and acid-activated bentonite (T) as treatments, each with three levels, namely 0, 5, 10 t ha-1 and three replications. Soil analysis performed included pH, organic carbon, CEC and exchangeable bases, while plant tissue analysis included leaf height and area. The results showed that the combination of biochar and acid-activated bentonite significantly increased soil pH, soil exchangeable K, soil exchangeable Na, and leaf area of maize plants. A single application of biochar significantly increased soil organic C and maize plant height. The application of acid-activated bentonite significantly increased the CEC of sandy loam soils.

One way to reduce carbon emissions is to prevent land cover change, especially forests for other uses in tropical areas such as forests in the Blega watershed area. This study aims to look at land cover change and its effect on surface carbon stock in the Blega watershed from 1990-2020. This research was conducted in the Blega watershed area through 6 stages, namely: 1) Geometric correction, 2) Band composite, 3) Training sample on Area of Interest (AoI), 4) Training sample test, 5) Land cover classification and 6) Carbon stock calculation. The results of image analysis of the Blega watershed area show that the average land cover in 1990, 2000, 2010, and 2020 are dry land agriculture (69%), plantation forest (11.2%), rice fields (8.77%), plantation forest (4.59%), ponds (2.65%), mixed dry land agriculture (1.56%), secondary mangrove forest (0.87%), settlements (0.70%), shrubs (0.63%) and the remaining open land. The land cover changed 1990-2000 from swamp scrub to dry land agriculture (8,819.81 ha), paddy fields (2,629.13 ha), and settlements (152.57 ha). The period 2000-2010 saw land cover change in Mixed Dryland Agriculture-Settlement of 654.14 ha. The 2010-2020 period saw the highest land conversion in paddy fields - ponds with an area of 4,571.08, scrub - paddy fields, and secondary mangrove forest - ponds with an area of 343.12 and 316.13 ha respectively, and a small portion of other land covers. Furthermore, in the 2010-2020 period, rice field land cover decreased by 4,302.7 ha. The change in land cover affects the change in carbon stock in the Blega watershed, which during the 1990-2020 period decreased by 25.98%.1990-2000 experienced a decrease of 19.41%, 2000-2010 and 2010-2020 experienced a decrease of 1.55% and 5.02% respectively. Keywords: carbon emissions, surface c stock, madura

Abstract

Ideally, the Pak Choy plant (Brassica Chinensis L) is cultivated with microenvironmental conditions of temperature 150C- 320C, humidity 60% - 80% and the same intensity of sunlight as other vegetable plants, namely in a vegetative vase of 300-400 micromols/m2/second and a period of generative 500-1000 micromols/m2/sec . The challenge of agriculture today is to meet the increasing need for food with limited land and uncertain plant microenvironmental conditions, one solution to this problem is planting using a plant factory system. Fuzzy logic has an effective method for controlling plant factory control systems, due to its flexibility and simple calculations. The purpose of this research is to find the PWM value in the plant factory control system that suits the optimal needs of pak choy vegetable cultivation. There are 4 stages in the research, namely the primary data input of the LED plant factory, Fuzzyfication, Fuzzy Interface System and Defuzzification. Data was taken using a lux meter and there were a total of 56 fuzzy rules and 4 fuzzy rules that did not have a value of 0. The lighting level/light intensity control system based on fuzzy logic was obtained with a PWM (Pulse Width Modulation) value of 872.1662 for a light intensity set point of 8000 Lux.

Abstract

Part of the dry land in Madura developed from parent material, namely sand sediments which have a low organic matter content. This study aimed to determine differences in the effectiveness of corn seed coating materials from bentonite, biochar, lignite, and biochar compost on the growth and yield of maize (Zea mays L.) under drought stress conditions. This study was conducted at the Integrated Laboratory and screen house of the Faculty of Agriculture, University of Jember, using a completely randomized design. The treatments tested in this study comprised two factors. The first factor was the treatment of coating materials, namely C0 = without coating (control), C1 = bentonite coating, C2 = biochar coating, C3 = lignite coal coating, and C4 = biochar compost coating. The second factor is the level of drought stress, namely K0 = control (100% KL moisture), K1 = Light stress (80% KL moisture), K2 = moderate stress (60% KL moisture), and K3 = severe stress (40% KL moisture). The results showed that the combination of seed coating agent treatment and drought stress had a significant effect on the parameters of plant height, number of leaves, leaf area, age of male and female flowers, cob length, cob diameter without husks, biomass dry weight, and production potential per hectare. The coal coating material and light drought stress 80% KL (C3K1) was the best combination of seed coating and drought stress treatment.

Abstract

Slow-release fertilizer can provide nutrients more efficiently; nutrients are released and available slowly so that they have the potential to be absorbed by plants. This study aimed to investigate the effects of several slow-release N fertilizers on the growth and yield of corn (Zea mays L.) in sandy soil. This research was carried out in the greenhouse and laboratory of the Faculty of Agriculture, University of Trunojoyo Madura. The experiment was arranged on a non-factorial completely randomized design. There were six treatment levels, namely P0 (uncoated urea fertilizer, applied into one application), P1 (uncoated urea fertilizer, split into three times applications), P2 (urea fertilizer with bentonite coating, P3 (urea fertilizer with biochar coating), P4 (urea fertilizer with coal coating), and P5 (urea fertilizer with biochar compost coating). All coated urea fertilizers were applied one time at the early growth of corn. The results showed that the application of slow-release N fertilizer had no significant effect on plant height, number of leaves, leaf area, cob length, diameter, plant fresh weight, plant dry weight, seed weight per plant, 100 seed weight, and flower age. However, the application of slow-release N fertilizer had a very significant effect on plant height at 42 DAP, the number of leaves at 14 DAP and 56 DAP, and leaf area at 28 DAP and 56 DAP. All coated urea fertilizers were as effective as uncoated urea on the growth and yield of corn.
