This study aimed to analyze the spatial variability of soil pH and soil temperature in irrigated paddy fields using a Geographic Information System (GIS) approach in Pakukerto Village, Sukorejo District, Pasuruan Regency. However, conventional management often overlooks the spatial heterogeneity of soil properties within irrigated schemes, erroneously assuming uniformity due to water distribution. The research was conducted using a field survey method with a descriptive–spatial approach. Soil pH and soil temperature were measured directly at 25 sampling points distributed across five areas using a soil tester, while the geographic coordinates of each sampling point were recorded using a global positioning system device. The collected data were processed and spatially analyzed using GIS software. Spatial interpolation was performed using the Inverse Distance Weighting method to generate continuous distribution maps of soil pH and soil temperature. The results showed that soil pH in the irrigated paddy fields ranged from acidic to alkaline conditions, while soil temperature varied between 25 and 34 °C, with a generally homogeneous spatial pattern and several localized zones exhibiting higher temperatures. The observed spatial variability indicated that land conditions were not uniform across the study area. The spatial mapping of soil pH and soil temperature provided valuable information for site-specific land management and supported the implementation of precision agriculture in irrigated paddy fields. These findings demonstrate that rapid spatial assessment using deterministic interpolation is a viable, cost-effective strategy for diagnosing soil constraints in similar smallholder tropical agroecosystems.

Water management is a crucial factor in optimizing the productivity of leafy vegetables, including green spinach (Amaranthus sp.), particularly under limited water availability. Appropriate timing of irrigation may influence plant growth dynamics and biomass allocation. The study aimed to evaluate different irrigation times on the growth and biomass distribution of green spinach. The study was using a single factor with a completely randomized design, namely irrigation time, consisting of three treatments: morning irrigation (07:00), afternoon irrigation (16:00), and a combination of morning and afternoon irrigation (07:00 and 16:00). The treatment was replicated six times, resulting in 18 experimental units. Irrigation volume was standardized based on field capacity. Growth variables observed involved plant height, stem diameter, and number of leaves, while production variables consisted of fresh and dry weights of shoots and roots, as well as the shoot-to-root ratio. Data were analyzed using analysis of variance, with by the Honestly Significant Difference (HSD) test at a 5% significance level. The irrigation timing significantly affected plant height, number of leaves, and shoot-to-root ratio, but had no significant effect on stem diameter or total fresh and dry biomass. Morning irrigation produced a higher shoot-to-root ratio, indicating more efficient biomass allocation to the edible parts of the plant. In conclusion, morning irrigation is recommended as a practical water management strategy to support vegetatif growth and improve resource use efficiency in green spinach cultivation.

Edamame is an agricultural commodity with high economic value and potential for development. The pod filling stage plays an important role in determining the success of pod production with premium quality standards. This study was conducted from April to August 2024 on the grounds of the Jember State Polytechnic. The objective of this study was to examine the effect of amino acid application and Plant Growth Promoting Rhizobacteria (PGPR) on edamame production and quality. This study used a Factorial Randomised Block Design (RAKF) with two treatment factors. The first factor was the concentration of amino acids derived from lemuru fish, consisting of five levels: 0 ml/L (control), 5 ml/L, 10 ml/L, 15 ml/L, and 20 ml/L. The second factor was the concentration of PGPR, consisting of two levels: 0 ml/L (as a control) and 150 ml/L. The results of the study data showed that the amino acid treatment produced significantly different results in terms of total pods, pods with two seeds, and the percentage of pods with seeds. Meanwhile, the PGPR treatment had a significantly different effect on the observed variables of total pods and filled pods. The amino acid treatment at a concentration of 15 ml/L was able to increase the number of filled pods and the percentage of filled pods. Meanwhile, the PGPR treatment at a concentration of 150 ml/L was able to increase the percentage of filled pods.

Legume plants play an important role in agricultural systems. Nitrogen is an essential nutrient required by plants for both vegetative and generative growth. Nitrogen-fixing bacteria commonly used in agriculture belong to the genus Rhizobium spp. Rhizobium is a Gram-negative bacterium that inhabits the rhizosphere region of plants. Agronomically, this bacterium has the ability to form symbiotic relationships with leguminous plants, which play a significant role in maintaining soil fertility. Peanut, soybean, yardlong bean, and mung bean were the legume crops used in this study. Isolation of Rhizobium bacteria was carried out using the serial dilution method from 10?¹ to 10??. The isolates obtained were subjected to hemolysis testing and morphological characterization on YEMA (Yeast Extract Mannitol Agar) medium. Blood agar medium was used for the hemolysis test. The highest population of Rhizobium bacteria was found in mung bean and yardlong bean rhizosphere soils, each with 3.0 × 10? CFU/g. Most Rhizobium isolates exhibited milky white, translucent white, and pink colony colors. A total of 16 isolates were obtained from soybean, 16 from yardlong bean, 7 from peanut, and 8 from mung bean. Morphologically, Rhizobium colonies were generally circular, flat, and exhibited whitish-pink to translucent coloration.

This study aims to determine the efficiency of tall coconut (Cocos nucifera L) marketing channels in Sungai Kakap District, Kubu Raya Regency, considering that farmers in the area still face fluctuating and low selling prices. The research employed a mixed-methods approach, involving 100 respondents consisting of farmers and other marketing actors. Data were analyzed quantitatively using marketing margin, farmer’s share, and marketing efficiency methods. The results identified four distinct marketing channels. It was found that Channel I (farmer – consumer) is the most efficient, with an efficiency percentage of only 3% and providing a 100% farmer's share. Conversely, the other three channels (Channel II, III, and IV) were deemed inefficient as their efficiency percentages significantly exceeded the 50% threshold (at 97%, 177%, and 260%, respectively). The high level of inefficiency is primarily influenced by the length of the distribution chain, which automatically increases marketing costs. Nonetheless, the majority of farmer respondents (77%) prefer Channel III due to the ease of transportation. These findings conclude that a shorter marketing channel results in a larger share of the price received by the farmer.

The objective of this study is to analyze the influence of land area and technology on the productivity of citrus and vegetable farmers in Saribudolok Sub-district, Silimakuta District, Simalungun Regency. A quantitative approach was employed using a survey method, by distributing questionnaires to 96 farmer respondents, determined using the Slovin formula. The data were analyzed using SPSS software, which included validity and reliability tests, classical assumption tests (normality, multicollinearity, and heteroscedasticity tests), multiple linear regression analysis, partial t-test, simultaneous F-test, and coefficient of determination test. The findings indicate that both land area and agricultural technology have a positive and significant influence on farmer productivity. Among these, agricultural technology has a more dominant effect compared to land area. The coefficient of determination, valued at 51.0%, suggests that these two variables explain more than half of the variation in farmer productivity. The conclusion of this research is that optimizing technology and land access are key factors in enhancing horticultural productivity in highland areas such as Saribudolok. These results offer practical implications for policymakers in designing agricultural programs that are tailored to local needs and efficient in resource utilization.
