Abstract

Cherelle wilt merupakan penyakit fisiologis pada tahap awal perkembangan buah kakao karena kegagalan perkembangan buah. Salah satu unsur yang diduga kuat menjadi penyebab adalah unsur boron yang ketersediannya sangat penting bagi tanaman karena berperan dalam perkembangan sel, metabolisme protein, asam amino, nitrat, lemak, karbohidrat, auksin dan fenol, fungsi membran, berperan dalam keberhasilan pembentukan bunga, pembuahan dan perkembangan buah. Tujuan penelitian untuk mengkaji dan meneliti tentang pengaruh boron terhadap layu pentil kakao. Penelitian dirancang menggunakan rancangan Randomized Complete Block Design (RCBD) dimana faktor A terdiri dari metode aplikasi pupuk yaitu lewat daun dan lewat tanah sedangkan faktor B adalah takaran pemberian boron yang terdiri dari tanpa pemberian pupuk , pemberian boron 1,5 g.pohon-1, 3 g. Pohon-1, 4,5 g.pohon-1 dan 6 g.pohon-1 setiap perlakuan diulang tiga kali, setiap ulangan terdiri dari 5 tanaman sehingga kombinasi perlakuan menjadi 2 x 5 x 3 x 5 = 150 tanaman. Parameter yang diamati adalah Boron total daun, viabilitas pollen, total pentil yang terbentuk, persentase pentil sehat, dan pentil layu. Hasil menunjukkan bahwa metode aplikasi pupuk boron berpengaruh terhadap layu pentil kakao. Metode aplikasi boron lewat daun dengan dosis 0, 4,5 dan 6 g.tanaman-1 memberikan nilai pentil layu yang lebih tinggi. Sedangkan metode aplikasi boron lewat daun dosis 1,5, dan 3 g.tanaman-1 serta metode aplikasi lewat tanah dosis 6 g.tanaman-1 memberikan persentase pentil sehat yang lebih tinggi. Metode aplikasi lewat daun dengan dosis 3 g.tanaman-1 adalah dosis maksimal yang mampu memberikan hasil tertinggi terhadap viabilitas pollen, jumlah buah, dan persentase pentil sehat.

Abstract

This study investigates the impact of boron fertilizer on physiological activities of cocoa trees, specifically focusing on boron content, nitrogen content, nitrate reductase activity, chlorophyll content, and photosynthesis rate in cocoa plant leaves. This research was arranged in a randomized complete block design with two treatment factors, which were the type of boron fertilizer application (soil and foliar fertilizer), and the dose of boron fertilizer (1.5, 3, 4.5, and 6 g plant−1 with 0 g plant−1 as a control). Data were then analyzed for variance differences (ANOVA) with α = 5%, followed by the Tukey test, and contrast orthogonal for comparing treated and control plants. The results showed that the dose of boron fertilizer and the type of fertilizer application used have a significant effect on the physiological activity of the cocoa plant. The dose of boron with soil application affects physiological activity in a linear pattern where each additional dose of boron will increase the activity of nitrate reductase, chlorophyll content, and photosynthetic rate. The dose of boron with foliar application affects physiological activity in a quadratic pattern, where the dose of boron in the range of 3 g plant−1 is the optimum dose that gives maximum results on nitrate reductase activity, chlorophyll content, and photosynthetic rate in the cocoa leaves. Therefore, it is considered that the application of boron fertilizer at a dose of 3 g plants−1 with the foliar application is more efficient in increasing physiological activity compared to the dose of boron with soil application.

Abstract

Potato self-sufficiency in Indonesia faces three main problems: rising air temperatures, limited availability of low-temperature land suitable for potato cultivation, and lack of high-temperature tolerant potato varieties. Therefore, it is necessary to identify the tolerance of potato variety to high-temperature. This research was conducted in two locations: the optimum temperature location and the high-temperature location, using nine varieties, are Agria, Andina, Amabile, Cingkariang, Granola L, Granola K, Margahayu, Olympus, and Tedjo-MZ. The study design uses a split plot with three replications. Differences in temperature as the main plot and varieties as subplots. Parameters observed were air temperature, growth, and yield of potato tubers. The analysis carried out were the Stress Sensitivity Index (SSI), Stress Tolerance Index (STI), Yield Stability Index (YSI), and Cluster Analysis. The results showed that there were no tolerant to high-temperature varieties. Based on the STI, only Olympus was a medium tolerant of high temperatures. Based on the Stress Sensitivity Index (SSI), four varieties are moderately susceptible to high temperatures (Olympus, Andina, Cingkariang, and Margahayu). The YSI analysis shows the same results as the SSI. The cluster analysis results showed harmony between the results of the stress index analysis and cluster analysis. Nine varieties had a high similarity (87.3%), meaning that all varieties had the same characteristics and less tolerance to high temperatures. Olympus was the more tolerant variety to high temperatures, followed by Andina, Cingkariang, and Margahayu. The four varieties consider promising potato lines in high-temperature areas.

Abstract

The accumulation of microplastics (MPs) in agricultural land may threaten food security and farmers' health, which is of interest. This study examined the implication of MPs contamination/pollution on the chemical properties of an Inceptisol on different slopes in the horticultural production center of Banuhampu Subdistrict, Agam District, West Sumatra Province. The soil samples were determined by purposive random sampling with a quantitative survey method. Sample testing was carried out using a randomized completely block design with five treatments, i.e., 25-45% in forests, and 0-8%, 8-15%, 15-25%, and 25-45% in fields at a depth of 0-20 cm. The Inceptisol contaminated with MPs has the following characteristics: pH = 5.01, EC = 0.09 dS m-1, Eh = 92.97 mV, mineral = 68.81%, OM = 31.19%, CEC = 60.67 cmol(+) kg-1, C = 2.13%, N = 0.81%, P2O5 = 6.46 ppm, K = 0.48, Ca = 1.59 cmol(+) kg-1, Mg = 0.62 cmol(+) kg-1 , and SO4 = 98.98 ppm. The concentration of MPs on the Inceptisol was 438.33 particles kg-1 with filament shape, transparent color, and large size (1-5 mm) were the most commonly found. Polymer types included polyamide 6, polystyrene, and polyethylene. The effect of slope level on the surface change charger of Inceptisols contaminated with MPs was insignificant. However, the effect was significant in OC, total N, K-exch, and available S. The implications of microplastic contamination/pollution did not have a significant relationship with the chemical properties of the soil. However, it has a negative relationship to redox potential (Eh), mineral composition, and Ca-exch.

Abstract

Appropriate weeds control is needed against weeds constraints in field, especially the organic field. With the appropriate management, weeding would benefit the organic field not only in reducing weeds but also in increasing nitrogen (N) availability in organic rice fields. This research aims to observe soil available N changes affected by weeding frequencies in organic paddy fields. Treatments applied were five weeding frequencies (WF) such as 0 WF, 2 WF, 4 WF, 6 WF, and 8 WF, to study the effect of various weeding frequencies on soil total N and available N ( NH4+ and NO3–) in the organic rice field. The soil in the conventional field was analyzed as a comparison to organic field soil. The results showed that soil C and N contents are similar in all treatments. Meanwhile, 6 WF performed the highest soil  NH4+ among organic plots (10.36 mg N kg–1) and 8 WF enhanced soil NO3– to the highest average among all plots (10.12 mg N kg–1). The treatment of 6 WF and 8 WF also maintain the increase of soil  NH4+ to 51 days after transplanting (DAT), meanwhile 0 WF, 2 WF, and 4 WF decreased after 40 DAT. Water samples from fields inlet-outlet and river showed that  NH4+ content found in water sample was higher than NO3–. We concluded that the more frequencies of weeding applied to organic fields potentially preserved soil inorganic N longer, which is very important in supporting rice growth.

Abstract

The utilization of wetlands as agricultural land requires specific processing techniques, which are relatively expensive and unaffordable for local farmers. The optimization of wetlands as agricultural land by local farmers is usually made by elevating a certain part using the adjacent soil material known as Surjan system. The land management using Surjan system increases the diversity of agricultural products and deals with inundation problems. However, its environmental impact has not been widely studied. The research was conducted by observing the land with Surjan system in Kulonprogo area to determine its characteristics. Interviews with farmers were conducted to determine land management techniques. Soil and gas emissions samples were taken based on the age of the crop. The characteristics of land with Surjan system and conventional rice field were then compared to determine the difference, and the implications of the two agricultural lands on the environment are discussed. Surjan system can increase land productivity, and it can be adopted easily by farmers in other areas with inundation problems. This system is a planting system consisting of mound (the raised beds) and tabukan (the sunken beds that remain inundated). The mound part can be planted with secondary crops, horticulture, and other dryland crops, while the tabukan part can be planted with rice and used for mina padi (rice-fish) farming system. Surjan system provides benefits for environmental management through the prevention of floods and eutrophication, as well as reduction of greenhouse gas emissions in the atmosphere. Land management through Surjan system affects soil pH, redox potential, and organic matter. Land with Surjan system produces lower methane gas emissions than conventional rice fields. It produces methane gas of 4.06 - 45.73 µg / m2 / minute, with soil pH, redox potential, and organic matter of 6.65 - 7.69, (-) 49 - 10 mV, and 1.28 - 3.59%, respectively

Abstract

Edamame soybean (Glycine max (L.) Merr.) cultivation in phosphorus-limited Andisols presents a formidable challenge due to restricted phosphorus availability despite high phosphorus retention. Unlocking the full potential of this crop demands innovative solutions. This study delves into the transformative effects of biochar and phosphorus fertilizer, individually and synergistically, on edamame soybean growth in Andisols. Employing a randomized complete block design, researchers investigate three types of biochar (B0: control, B1: biochar pellets, B2: biochar powder) and four phosphorus fertilizer rates (P0: control, P1: 27 kg ha-1 P2O5, P2: 54 kg ha-1 P2O5, P3: 81 kg ha-1 P2O5). The bamboo-derived biochar was produced using the Kon-tiki method at ±500 °C. The study reveals no significant interaction between biochar and phosphorus fertilizer. Individually, treatments with B1, B2, and phosphorus fertilizers significantly enhance ammonium, nitrate, and phosphorus availability compared to B0 and P0. Biochar-induced modifications improve phosphorus and nitrogen absorption by roots, resulting in increased shoot dry weight and the root/shoot ratio. However, the number of leaves is solely influenced by phosphorus fertilizer treatment. Additionally, both biochar and phosphorus fertilizers contribute to nitrate reductase activity, root volume, an increased number of pods per plant and higher protein content in edamame soybeans. B2 outperforms B1 and high P3 intensifies this effect, improving nutrient uptake and yield. In summary, biochar and phosphorus fertilizers demonstrate significant potential to revolutionize edamame soybean cultivation in phosphorus-limited Andisols, optimizing pod number per plant and enhancing quality with elevated protein content.

Abstract

The combination of fertilizer treatment with biochar has shown to be a sustainable and ecologically friendly method of increasing soil fertility and crop productivity. However, its combined impact on nutrient availability and rice yield is still unclear. This study aimed to investigate the effect of bamboo biochar produced by the Kontiki method in combination with nitrogen and phosphorus fertilization on nutrient availability in the soil and the productivity of rice. The treatment factors included the fertilizer combination factor (B) consisting of B1 (N + P fertilizer + Biochar), B2 (N fertilizer + Biochar), B3 (P fertilizer + Biochar), and B4 (Biochar + no fertilizer), and the biochar dose factor (F) comprising F0 (0 tons ha⁻¹), F1 (5 tons ha⁻¹), and F2 (10 tons ha⁻¹), resulting in 36 experimental plots with 12 treatment combinations. Measurement of ammonium and nitrate concentration in the soil started on the 15th day after planting, following the measurement of the growth of rice plant biomass with an interval of 15 days. The measurement of available P in the soil was started on day 45 after planting and continued until harvesting time with the same time intervals as the measurements of ammonium and nitrate. The study found that combining bamboo biochar treatment with nitrogen and phosphorus fertilizer greatly boosted the availability of nitrogen (ammonium and nitrate) and availability of P in the soil. Treatment combinations improved lowland rice yield (P < 0.05) by increasing plant height, number of tillers, dry weight of shoots and roots, grain weight per clump, 1000-grain weight, and grain yield.
