Abstract

The aim of this research is to determine the effects of various types of ash on the acidity and ionic status of peat soil, as well as to investigate the relationship between soil acidity and the ionic status of peat soil treated with these different types of ash. The research employed a one-factor completely randomized design (CRD). The factor studied was the type of ameliorant, consisting of four levels: a0 = no ameliorant, a1 = rice husk ash, a2 = sawdust ash, and a3 = empty oil palm bunch ash. Each treatment was replicated five times, resulting in a total of 20 experimental units. The results indicated that the application of ash significantly affected the acidity (pH), redox potential (Eh), Electrical Conductivity (EC), and Cation Exchange Capacity (CEC) of peat soil at various observation times. The relationships observed were as follows: soil pH and Eh exhibited a moderate negative correlation (r = -0.522 at three  months after treatment), Eh and EC showed a strong negative correlation (r = -0.643 at three months after treatment), EC and CEC had a positive correlation (r = 0.620 at 18 months after treatment), and CEC with pH demonstrated a positive correlation (r = 0.550 at 12 months after treatment). The most effective ameliorant was found to be empty oil palm bunch ash (a3), followed by sawdust ash (a2).

Abstract

Ngrogung is one of the sand mining areas in Ponorogo, East Java, Indonesia. Post-mining, this area often remains underutilized. One potential application for this former sand mining land could be the cultivation of durian plants. The research aims to determine land characteristics and evaluate the level of land suitability for Durian cultivation. The research was conducted using survey methods. Determining the research location was carried out purposively based on conditions in the field. The study area is 20 hectares, which is an ex-sand mining area. Determination of representative samples was carried out in a zigzag manner to obtain a representative sample. Soil samples were taken to a depth of 100 cm, representing the root area of the durian plant. Sample analysis was carried out using the method issued by the Land Resources Center, and the results obtained were analyzed using matching methods based on FAO criteria. The results showed that the actual land suitability of the ex-sand mining in Ngrogung Village is S3nr-2 covering an area of 10 hectares with alkaline saturation limiting factor, S3nr-4; eh-2 with C-organic and erosion hazard limiting factor 6 hectares, S3nr-4; rc-2 with C organic and crude material limiting factor 4 hectares. The potential suitability of ex-sand mining land based on FAO criteria can be categorized as S2 (quite suitable), so it requires technological input such as adding organic matter, making terraces, and planting according to contours.

Abstract

Black soybeans in Indonesia have high economic value due to their potential for processing into various products and their health benefits. The high utilization of black soybean is supported by its rich nutritional content, particularly the protein levels in its seeds. There is a gap between the demand for and availability of black soybeans in Indonesia. Effective measures are needed to increase black soybean yields. One approach is to enhance the efficiency of organic fertilizer use by applying rice straw biochar as a soil amendment and Rhizobium as a biofertilizer to improve the growth and yield of black soybeans. This study was conducted using a two-factor experimental design with doses of rice straw biochar (0, 10 t.ha-¹, and 15 t.ha-¹) and doses of Rhizobium (0, 5 g.kg-¹ seed, 10 g.kg-¹ seed, and 15 g.kg-¹ seed). An interaction was observed between the application of 10 t.ha-¹ of biochar and 5 g.kg-¹ of Rhizobium, which significantly affected the yield of black soybean, including the number of filled pods per plant, seed weight per plant, harvest yield per hectare, and total seed protein content.

Abstract

Rice is Indonesia’s first staple food crop, planted throughout the year in irrigated rice fields. Finding an efficient method of producing rice seedlings outside the paddy fields is necessary. This research aims to determine the optimal shelf levels in open fields to support seedling rice growth and chlorophyll content and identify suitable lighting alternatives to light-emitting diode (LED) growth lights for supporting indoor seedling rice growth. This study used thirteen treatment variations, each repeated five times in a Randomized Block Design. The observational data were analyzed utilizing ANOVA, standard deviation, correlation, and the Honesty Significant Differences (HSD) test at a 5% significance level. The study's results were in the open field. The seedlings on the third level of shelves received the highest intensity of sunlight so that the chlorophyll content, seedling height, and number of leaves were relatively higher than those on the second and first level shelves. In greenhouse cultivation, the substitution for LED grows light until 150 Watts between 12 and 14 hours, causing low light intensity, chlorophyll levels, seedling height, and fewer leaves than in open fields.

Abstract

Using manure in the form of liquid organic fertilizer (LOF) influences the heavy metal levels absorbed by plants, which can affect both plant quality and human health. This research aims to assess the impact of LOF on soil pH, total nitrogen, available phosphorus, lead levels, and the fruit yield of tomatoes. A factorial completely randomized design (CRD) was employed, with the first factor being three types of LOF from chicken, goat, and cow manure and the second factor being three doses of LOF: 5, 10, and 15 mL. The study utilized tomato plants grown in latosol soil. Results indicated that the application of LOF from the three manure types affected soil nitrogen, soil lead, and tomato yield. The addition of LOF also influenced lead content and tomato production. However, the use of chicken manure is not recommended due to high lead accumulation in soil and plants. The optimal LOF dose was found to be 5-10 mL, which maintained lead levels within safe limits. The best tomato fruit yield was achieved with 5 mL of goat manure LOF, resulting in low metal accumulation.

Abstract

This study aimed to identify the most effective combination of seed treatments and fungicide applications to control downy mildew on corn seeds. It also evaluated the efficacy of various fungicides in suppressing the spread of downy mildew. The research was conducted from October 2021 to January 2022 in Banggle Village, Kanigoro District, Blitar Regency, Central Java Province. The methodology employed a randomized complete block design, with treatment factors including seed treatment and fungicide spraying. Four treatment packages were utilized: one control group with no seed treatment or fungicide application and three others as comparators. Each treatment was replicated four times. The active ingredients used for seed treatment and field spraying included Dimethomorph, Pyraclostrobin, Oxathiapiprolin, and Fenamidone. The results indicated that downy mildew on corn emerged during the fourth week after planting. Corn treated with the fungicide packages exhibited significantly better outcomes compared to the control group. The most effective treatment package involved seed treatment with Dimethomorph and Pyraclostrobin, followed by spraying with Dimethomorph on the seventh day after planting, Oxathiapiprolin on the fourteenth day, and Dimethomorph once again on the twenty-first day after planting. This combination achieved the highest efficacy index of 70.67%.

Abstract

The aim of the research was to obtain the most precise pattern of development of bacterial disease (Xanthomonas campestris pv. vesicatoria) and determine the relationship between the intensity of bacterial spot disease and yield loss of tomato plants (Lycopersicum esculentum Mill.). The research was carried out in Solok Regency at an altitude of 388 m above sea level from June to December 2022. To determine the most appropriate pattern of disease development, two mathematical models were tested: Logistic and Gompertz’s models, which were corrected by Campbell and Madden as well as Neher and Campbell. The yield loss estimation method uses a single disease forecasting system with a single critical time type. The disease was measured at several plant ages according to the growth phase from the base point of 0 DAP, then at ages 26, 31, 36, 41, 46, 51, 56, 61, 66, and 71 days after planting. Variation in disease severity was created by inoculating plants through several inoculum densities. The results showed that the development of Xcv disease follows Gompertz’s model, and the critical time to determine the relationship between disease intensity and yield loss follows the rank regression model with a critical time at plant age of 31 days after planting.

Abstract

Coffee plants are one of the plantation crops cultivated in Indonesia. Coffee cultivation is generally carried out in agroforestry systems with shade plants such as rubber and sengon. The type of shade planted in coffee cultivation can affect temperature, humidity, and light intensity, all of which can influence the agronomic characteristics of coffee plants. This study aimed to analyze the effects of temperature, humidity, and light intensity on the agronomic characteristics of coffee plants grown under two types of shade in the agroforestry system. The research was conducted by measuring temperature, humidity, light intensity, and the agronomic characteristics of coffee plants in each observation plot. The data obtained were analyzed using SEM analysis and correlation methods. The average temperature in the agroforestry areas with rubber and sengon was 29.30˚C and 29.42˚C, respectively. The average humidity in the agroforestry areas with rubber and sengon shade was 65.72% and 64.76%, respectively. The average light intensity in the agroforestry areas with rubber shade was 35.79%, while in the sengon shade, it was 45.36%. Temperature and light intensity in both agroforestry systems exhibit a positive correlation with the number of productive branches and stomatal density of coffee plants. In contrast, humidity shows a negative correlation with chlorophyll content.

Abstract

Cucumber is one of the most widely consumed vegetable crops globally. Rice-washing water has not been previously explored as a potential source for producing secondary metabolites from antagonistic fungi. Phytophthora species frequently affect cucumber seedlings, leading to crown and root rot. This research aimed to assess the efficacy of washing water from various rice types on the conidial density of Trichoderma harzianum T10 and its impact on crown and root rot in cucumber seedlings and overall plant growth. We conducted four treatments with rice washing water in vitro under a completely randomized design, comprising six replicates. Five treatments were evaluated in planta under a randomized block design with five replicates. The observed variables included conidial density, incubation period, disease incidence, disease progression expressed as the Area Under the Disease Progress Curve (AUDPC), plant height, fresh weight, and root length. The results indicated that washing water from glutinous rice provided the optimal medium for T. harzianum T10, yielding a conidial density of 10.3 × 10-6 conidia mL-1, representing a 66.02% increase compared to washing water from white rice. The crude secondary metabolites produced by T. harzianum T10 in glutinous rice washing water significantly extended the incubation period and reduced disease incidence and AUDPC values by 40.34, 62.07, and 69.41%, respectively, compared to the control. Furthermore, the secondary metabolites from T. harzianum T10 in glutinous rice washing water enhanced plant height, fresh weight, and root length by 91.81, 92.42, and 95.21%, respectively, compared to the control.

Abstract

The optimal growth of soybean plants is critically dependent on the availability of essential nutrients in the soil, particularly nitrogen (N), phosphorus (P), and potassium (K). Plants achieve optimal growth when nutrient levels exceed deficiency thresholds. A significant challenge in soybean cultivation at the farmer level is the precise determination of fertilizer dosage and timing of application. This study presents an Internet of Things (IoT)-based device for the real-time detection of NPK nutrient content in soil, aimed at enhancing soybean yields. The device enables timely and accurate nutrient application, minimizing the soil's residual fertilizer risk, which can lead to environmental pollution and decreased land productivity. Field experiments were conducted to evaluate NPK fertilization methods on soybean crops in two distinct soil types, namely Vertisol and Entisol. The methodology involved comparing local farmers' fertilization practices with the recommendations derived from the NPK detection device. Results illustrated a significant increase in soybean yields when fertilization was performed according to the device's recommendations, yielding an increase from 1.2 to 1.79 t.ha-1 on Vertisol soil and from 1.75 to 2.57 t.ha-1 on Entisol soil.
