Abstract

weet corn productivity in Indonesia is still in the low category. One of the causes is the problem of soil with low pH. Soil with a low pH causes the availability of nutrients to decrease, thereby inhibiting plant growth and development. Efforts can be made to add dolomite, because hydrolyzed dolomite can increase nutrient availability in the soil. Therefore, this research was carried out with the aim of analyzing the effect of adding various doses of dolomite on soil chemical properties, plant uptake of Ca, Mg and P, population of phosphate solubilizing bacteria, and sweet corn productivity in the Tegalan Land of Junrejo Village, Batu City, East Java. The research design used a randomized block design (RAK) consisting of 9 treatments with 3 replications. Treatment consisted of: M0 = control; M1 = 100% N, P, K; M2 = 100% N,P,K + 100% Kieserite; M3 = 100% N,P,K + 50% Dolomit; M4 = 100%  N,P,K + 100% Dolomit; M5 = 100%  N,P,K + 150% Dolomit; M6 = 75%  N,P,K + 50% Dolomit; M7 = 75%  N,P,K + 100% Dolomit; M8 = 75%  N,P,K + 150% Dolomit. The data was analyzed for diversity using R studio software and continued with the DMRT (Duncan Multiple Range Test) test at 5% level. Next, to see the relationship and influence between parameters, correlation and regression tests were carried out. The findings demonstrated that adding 2.8 tonnes of dolomite per hectare might raise soil CEC (50.61%) and pH (13.41%). In addition, the addition of 4.2 tons/ha of dolomite was able to decrease soil P-available (5.65%), increase Ca-dd (26.4%), Mg-dd (85%), Ca absorption (165.12%), Mg absorption (366.67%), P absorption (78.57%), and sweet corn yield (78.04%). The addition of different doses of dolomite did not significantly alter the overall population parameter of phosphate-solubilizing bacteria. Furthermore, the link between sweet corn yield and nutritional absorption was both robust and weak. The increase in sweet corn output was impacted by P, Ca, and Mg absorption by 54.54%, 41.21%, and 42.79%, respectively.

Abstract

The range between boron deficiency and toxicity in plants is utterly narrow, so that the certain dose of boron fertilizer is required for plants. Indicators of optimum boron fertilization can be measured from plant production and boron use efficiency (BUE) value. BUE influenced by the amount of soluble B-soil, type of B fertilizer, amount of boron input, type of plant, and adequacy of available macronutrients (NPK). However, excessive application of NPK base fertilizer from inorganic fertilizers can trigger soil degradation. Currently, there has not been much research that measures the reduction in the dose of NPK base fertilizer combined with boron fertilizer on plant BUE. The combination of reducing the dose of NPK base fertilizer and boron fertilizer was tested on sweet corn plants on production and BUE. This study was conducted with a randomized block design with 7 treatments, namely without fertilization (K0), base fertilization (D1), 100% base fertilization and 50–15% borate (D2–D4), and 75% base fertilization and 50–15% borate (D5–D7). The results of the initial soil analysis showed low boron content in the soil, so borate fertilization was required to provide nutrients for sweet corn plants. Application of NPK base fertilizer (100%) and addition of borate fertilizer at a dose of 50-100% (~3-6 kg/ha) significantly increased growth, plant biomass, B uptake, boron recovery efficiency (BRE), and B fertilizer efficiency ratio, compared to lower NPK-base fertilizer. Based on the estimated response curve, the recommended dose to achieve optimum-maximum sweet corn production and maximum boron recovery efficiency is 100% macro inorganic fertilization (urea, SP-36, KCl) combined with 5.72-6.75 kg/ha borate fertilizer.

Abstract

Coffee agroforestry systems have great potential in optimizing the dual function of carbon and biodiversity conservation, especially in areas with high land use pressure. However, although coffee agroforestry has been widely practiced in Indonesia, the specific relationship pattern between carbon stocks and vegetation biodiversity is still not well understood. This study aimed to evaluate (1) the role of coffee agroforestry in maintaining vegetation diversity and carbon sequestration compared to disturbed forests (HT) and (2) the relationship between carbon stocks and biodiversity at various plant growth stages. Three land use systems were  selected such as HT and complex (AFM) and simple (AFS) coffee-based agroforestry systems. The number of trees, species richness (R), Shannon-wiener index (H’), species evenness (E), and carbon stocks were measured in 12 plots (100 m x 20 m) for each vegetation growth stages (seedlings, saplings, poles, and trees). The results showed that the H index in coffee agroforestry was generally low to moderate (0.57-2.05), with the highest diversity in the tree category. The diversity level of AFM could mimic HT. In terms of carbon stock, HT had the highest stock (82±19 Mg ha-1), while total carbon stock showed a positive relationship with H index in all vegetation stages (R2=0,13-0,57). In contrast, the relationship between soil carbon stock and H index tended to be weak (R2=0,10). This study emphasizes the importance of maintaining total carbon stock through diverse vegetation in agroforestri systems to support climate change mitigation and biodiversity conservation.

Abstract

Land evaluation is a process of assessing land resources to determine their suitability for specific purposes. This study aimed to evaluate the land suitability for maize (Zea mays L.) in Sipahutar District, North Tapanuli Regency, using a semi-detailed level analysis (1:50,000). The physical and environmental characteristics of the land were obtained from secondary data and analyzed using the matching method, which compared land characteristics with the optimal requirements for maize cultivation. The research area consisted of four land units (I-IV). The results indicated that land unit I fell within the N (unsuitable) class due to the limiting factor of sandy soil texture, that is difficult to overcome. Meanwhile, land units II-IV were classified as S3 (marginally suitable) due to limiting factors such as shallow rooting depth, which significantly affected productivity. These limitations are challenging to address without significant intervention, such as government support or investments from large-scale enterprises. The study highlights the need for targeted land management strategies to optimize maize production in the region.

Abstract

Soil types such as Entisol have low nutrient availability and water-holding capacity. Shrimp waste organic fertilizer and coconut shell biochar can be used to improve the physical and chemical properties of Entisol soil. The purpose of this research was to determine the effect of shrimp waste liquid organic fertilizer and coconut shell biochar on the availability of N, P, and K in the soil for the growth of Pakcoy. The research used a Completely Randomized Design (CRD) with two factors. The first factor was the concentration of shrimp waste liquid organic fertilizer consisting of P0 = 0 mL/L, P1 = 25 mL/L, P2 = 50 mL/L and P3 = 75 mL/L. The second factor was the dosage of coconut shell biochar consisting of B0 = 0 ton/ha, B1 = 10 ton/ha, B2 = 15 ton/ha and B3 = 20 ton/ha. The preliminary analysis parameters consisted of pH H2O, C-organic, N-available, P-available, K-available, N-total, P-total, K-total, and CEC. The research results were analyzed by using Analysis of Variance (ANOVA), and to determine the differences between treatments, a 5% DMRT (Duncan Multiple Range Test) was conducted. The research results indicate that the use of liquid organic fertilizer from shrimp waste with a concentration of 50 mL/L and a dose of coconut shell biochar at 20 tons/ha can increase the organic carbon content in the soil from 0.03% to 0.05%. A concentration of 75 mL/L for liquid organic fertilizer from shrimp waste and a dose of 20 tons/ha for coconut shell biochar can increase the available nitrogen content in the soil from 16.24 ppm to 40.67 ppm. There is no interaction with the height, number of leaves, anda root length of Pakcoy plants.

Abstract

The increasing demand for land has resulted in the reduction of potential agricultural land. Land suitability evaluation is an effort that can be made to determine the capacity of land for a particular commodity or crop development through various standardized land use requirements. East Java as a region that supplies vegetable commodities on a national scale still requires various efforts to optimize land use. This research aimed to identify areas that have potential land for cultivating potatoes. This identification was carried out using remote sensing which was then cross-checked with actual potato production data from each region in East Java Province. Based on data processing that had been carried out, in general, East Java is dominated by areas with land suitability classes in class N (not suitable), S3 (marginally suitable), and S2 (quite suitable). Lowland areas are dominated by class N (not suitable) because the land characteristics do not meet the requirements for growing potato plants. Meanwhile, the S3 and S2 classes are spread across the highlands with land units that meet the requirements and characteristics of land for cultivating potatoes. Efforts for classification, conservation, and so on become a unity to optimize and increase potato production in each region.

Abstract

The decreasing land area for coffee cultivation in Indonesia has led to a reduction in coffee production. The availability of land with potential for coffee plantation is also decreasing. As a consequence, coffee is cultivated on less fertile lands, such as lands dominated by clay fraction. This land generally has a low pH so that the nutrient content is more absorbed in Al and Fe which react in an acidic environment. Furthermore, heavy texture of soil also inhibits root growth, making it difficult for plants to absorb nutrients. In this study, biopore infiltration holes were used as a solution to improve acidic soil with a dominant clay fraction. The research was conducted at Agrotechnopark Jatikerto, Malang Regency and the soil analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, University of Brawijaya during 2020-2022. This research was conducted experimentally with a group randomized design. There were four treatments in this study, namely 1) control/no biopore, 2) 30 cm empty biopore, 3) 30 cm biopore + 2.12 kg compost fertilizer, and 4) 30 cm biopore + 1.05 kg goat manure fertilizer.  The results showed that biopore infiltration holes added with compost or goat manure fertilizer were able to increase pH, soil organic C, CEC, BS, and total N-P-K nutrients. Furthermore, the increase in organic C and total N-P-K nutrients in the study area was also directly proportional to the increase in chlorophyll content and coffee production. The increase in chlorophyll content and coffee production is a result of the increase in chlorophyll content and coffee yield.

Abstract

Soil serves as a medium for the absorption of greenhouse gases due to its organic carbon content; however, its capacity to absorb greenhouse gases has been declining. One of the contributors to carbon dioxide (CO2) emissions in agriculture is soil microorganism respiration, while high nitrogen (N) loss is attributed to its mobility. The application of biochar has the potential to reduce greenhouse gas emissions and improve soil quality. This study aimed to analyze the effects of different types and doses of biochar on reducing CO2 emissions, increasing nitrate levels, and enhancing microorganism populations. The research was conducted in the Soil Laboratory of Agroecotechnology, Malikussaleh University, using a completely randomized factorial design (CRD) with two treatment factors. Factor 1 was the type of biochar: (J1) rice husk biochar, (J2) giant bamboo biochar, and (J3) sweet corn cob biochar. Factor 2 was the biochar dosage: (D0) 0 tons ha⁻¹, (D1) 10 tons ha⁻¹, (D2) 20 tons ha⁻¹, (D3) 30 tons ha⁻¹, and (D4) 40 tons ha⁻¹. Parameters analyzed included CO2 emissions, soil nitrate levels, and microorganism populations. The results showed that rice husk biochar effectively reduced CO2 emissions from soil microorganism respiration to 4.08 kg CO2 ha⁻¹ hour⁻¹, increased soil nitrate levels to 8.14 ppm, and enhanced microorganism populations. The optimal biochar dosage was 30 tons ha⁻¹.

Abstract

Climate is an important factor which influences the growth and productivity of oil palm. The current oil palm cultivation system is vulnerable to climate change. For example, there was a decline in global oil palm production in 2015 due to ENSO, particularly affecting Southeast Asia. Extreme drought causes oil palm plants to experience water stress, while forest fires due to drought inhibit the photosynthesis process. A comprehensive study of the Systematic Literature Review was carried out using bibliometric analysis, systematic review and Meta-Analysis (PRISMA) methods, using the search engines Scopus and ScienceDirect with the keywords “palm AND oil AND production AND climate AND change”, “impact AND climate AND change AND coconut palm AND oil”, “palm AND oil AND adaptation AND climate AND change”, “palm AND oil AND mitigation AND climate AND change”. A thorough scientific literature review obtained 1331 papers from Scopus and ScienceDirect. Out of these, only 26 articles were selected for further examination. Based on the literature, there are several strategies for increasing oil palm productivity in the era of climate change. These strategies can be done through agronomic management, providing fertilizer from oil palm biomass, and maintaining irrigation for water availability. This literature study provides recommendations for strategies for increasing oil palm productivity in the face of climate change.
