Abstract

Selama masa pertumbuhan tanaman membutuhkan nutrisi. Penambahan pupuk anorganik urea sebagai unsur hara nitrogen seringkali tidak efektif karena siffat urae yang cepat tersedia sehingga potensi hilang sangat besar baik melalui penguapan maupun pelindian. Teknologi pupuk lepas lambat menjadi alternatif untuk menjamin ketesediaan hara N, efisiensi serapan hara N bagi tanaman, serta kesuburan sifat tanah. Efektivitas pupuk lepas lambat dapat dipengaruhi oleh faktor bahan pendukung. Potensi jenis bahan pendukung pembungkus urea yang berasal dari bahan organik sangat besar, seperti arang sekam, arang tempurung kelapa dan limbah udang. Penelitian ini bertujuan mengkaji pengaruh bahan pembungkus formula pupuk lepas lambat Urea-Organik terhadap perubahan sifat kimia tanah dan ketersediaan hara Nitrogen. Penelitian dilaksanakan adalah percobaan inkubasi yang dilakukan dalam laboratorium (Insitu) dengan perlakuan : Kontrol (tanpa perlakuan), F1 (Urea), F2 (Urea-arang sekam), F3 (Urea-arang tempurung kelapa), F4 (Urea-limbah udang). Parameter yang diamati yaitu pH tanah, kandungan C-Organik dan N-Nitrat tanah dari sampel tanah yang diambil pada 0, 14, 28, 42, dan 56 hari setelah inkubasi perlakuan. Hasil penelitian menunjukkan bahwa penggunaan arang sekam, arang tempurung kelapa, dan limbah udang sebagai bahan pembungkus urea dalam formula pupuk lepas lambat mampu meningkatkan ketersediaan hara nitrogen (N-Nitrat), serta mampu memperbaiki pH tanah dan kandungan bahan organik tanah dari sebelum perlakuan. Dalam hal uji korelasi antara pH, kandungan C-organik dan kandungan N-Nitrat menunjukkan korelasi yang tidak signifikan. Oleh karena itu perlu ada penelitian pembanding yang dilaksanakan di lapangan dengan beragam faktor yang mempengaruhi.

Abstract

Marginal land has low productivity due to its limited soil fertility, especially in terms of nitrogen (N) availability. The use of nitrogen-fixing bacteria and shrimp waste as alternative organic fertilizers can increase nitrogen use efficiency in sweet corn (Zea mays saccharata), which is an important food commodity. This study aims to determine the ability of nitrogen-fixing bacterial isolates to increase N nutrient use and their effect on the growth and production of sweet corn when applied together with shrimp waste. This study was conducted using a randomized block design (RAK) with a treatment of 20 tons/ha of shrimp waste and chemical fertilizer (50% Urea + 100% SP-36 + 100% KCl) with the addition of nitrogen-fixing bacterial isolates, consisting of 5 treatments and 4 replicates, namely no fertilizer, shrimp waste, and nitrogen-fixing bacteria. Other treatments were control, which was 100% Urea + 100% KCL + 100% SP-36; then isolate BPN1; isolate BPN2; isolate BPN3. The results of the study show that the application of nitrogen-fixing bacteria and shrimp waste technology packages can increase soil organic carbon content, nitrogen nutrient uptake, nitrogen nutrient uptake efficiency, and agronomic efficiency of sweet corn crops on marginal land. In addition, this technology can also reduce urea fertilizer use by up to 50%. This technology has the potential to be an environmentally friendly solution to support sustainable agriculture on marginal land.

Abstract

Penyakit antraknosa yang disebabkan oleh jamur Colletotrichum gloeosporioides merupakan kendala utama dalam budidaya cabai rawit. Penelitian ini bertujuan untuk mengkaji potensi kitosan sebagai agen penginduksi ketahanan tanaman (ISR) dan biostimulan, serta membandingkan efektivitasnya dengan fungisida dalam mengendalikan penyakit antraknosa berdasarkan waktu aplikasi yang berbeda. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan delapan perlakuan dan tiga ulangan. Perlakuan terdiri dari Kontrol Negatif (P0-: tanpa inokulasi/pengendalian), Kontrol Positif (P0+: inokulasi penyakit), tiga variasi waktu aplikasi fungisida (P1, P2, P3), dan tiga variasi waktu aplikasi kitosan (P4, P5, P6). Waktu aplikasi yang diuji adalah dua minggu sebelum inokulasi, bersamaan inokulasi, dan dua minggu setelah inokulasi. Parameter yang diamati meliputi intensitas serangan antraknosa pada daun dan buah, efektivitas pengendalian, serta parameter pertumbuhan tanaman (jumlah akar, panjang akar, berat basah dan kering akar serta berat basah dan kering tajuk). Hasil penelitian menunjukkan bahwa penggunaan kitosan efektif dan setara dengan fungisida dalam menekan intensitas serangan antraknosa. Perlakuan aplikasi kitosan dua minggu sebelum inokulasi (P4) memberikan hasil yang paling optimal, yaitu intensitas serangan pada buah yang paling rendah (38,6%) dan efektivitas pengendalian yang paling tinggi (19,99%). Hal ini mengindikasikan bahwa aplikasi kitosan di awal berperan kuat dalam menginduksi sistem pertahanan tanaman sebelum patogen menyerang. Selain itu, kitosan juga berfungsi sebagai biostimulan yang signifikan meningkatkan pertumbuhan vegetatif, ditunjukkan oleh peningkatan berat basah/kering serta perkembangan akar dan tajuk. Anthracnose disease, caused by the fungus Colletotrichum gloeosporioides, is a major constraint in chili pepper (Capsicum frutescens) cultivation. This research aimed to investigate the potential of chitosan as an agent for inducing plant resistance (ISR) and as a biostimulant, while comparing its effectiveness with fungicides in controlling anthracnose based on different application timings. The study employed a Randomized Block Design (RBD) with eight treatments and three replications. Treatments included Negative Control (P0-: no inoculation/no control), Positive Control (P0+: disease inoculation), three variations of fungicide application timing (P1, P2, P3), and three variations of chitosan application timing (P4, P5, P6). The application timings tested were two weeks before inoculation, simultaneous with inoculation, and two weeks after inoculation. Observed parameters included the incidence and severity of leaf and fruit anthracnose, control effectiveness, and plant growth parameters (number of roots, length of roots, fresh and dry root weight, and fresh and dry shoot weight,). The results showed that the use of chitosan was effective and comparable to fungicides in suppressing anthracnose severity. The treatment involving chitosan application two weeks before inoculation (P4) yielded the most optimal results, exhibiting the lowest fruit anthracnose severity (38.6%) and the highest control effectiveness (19.99%). This indicates that early chitosan application plays a strong role in inducing the plant's defense system before patogen attack. Furthermore, chitosan also functioned as a biostimulant, significantly enhancing vegetative growth, as evidenced by the increase in fresh/dry weight and the development of both roots and shoots.

Abstract

Intercropping is acknowledged as an effective agricultural intensification strategy for limited land. Planting time is an important factor in intercropping systems because it may intensify canopy overlap and shading, particularly because both crops rely on the C3 photosynthetic pathway, potentially reducing growth and yield. This study examined the effect of different planting times for cucumber (Cucumis sativus L.) and peanut (Arachis hypogaea L.). The study was conducted from October 2023 to February 2024 with a one-factor randomized block design. Five treatments were applied: simultaneous planting and cucumber planting at 1, 2, 3, and 4 weeks after peanuts, each replicated five times. Several data were analyzed using analysis of variance (F-test), followed by Tukey’s HSD test at the 5% significance level. This study confirms that differences in planting time between cucumbers and peanuts significantly affect soil macronutrient dynamics, growth and production, and land use efficiency. Soil macronutrient analysis showed that simultaneous planting (P1) resulted the highest soil nitrogen increase (0.38%). However, this treatment also caused a reduction in phosphorus to 15.15 mg per 100 g of soil and potassium to 13.48 mg per 100 g of soil. In contrast, excessive delay (P5) caused nitrogen to drop to 0.11% and phosphorus to decline to 14.19 mg per 100 g soil, despite potassium remaining relatively high (17.87 mg per 100 g of soil). Simultaneous planting produced the highest vegetative growth of cucumber, with an average of 40.68 leaves per plant, the greatest fruit length (22.16 cm), individual fruit weight (414.55 g), and total fruit weight per plant (2498.39 g). Delaying cucumber planting resulted in the lowest value of 828.45 g in P5. The highest pod weight was recorded in P1 at 62.46 g per plant. In contrast, planting cucumbers one week after peanuts (P2) resulted in the lowest peanut yield, at only 47.14 g per plant. All treatments achieved LER values greater than 1, confirming the superiority of intercropping over monoculture. The highest LER was obtained in P1 (1.61). In conclusion, simultaneous planting of cucumbers and peanuts provides the most optimal balance between soil nutrient utilization, crop growth, yield, and land use efficiency. Therefore, synchronized planting time is a key management strategy for improving productivity and sustainability in cucumber–peanut intercropping systems under limited land conditions.

Abstract

The limited availability of fertile land is a strong reason to utilize marginal land. Marginal land has potential for agricultural development because it has relatively high total phosphorus, but this phosphorus is in a form that is not available to plants. The use of phosphate-solubilizing bacteria (PSB) can be an alternative to change this form. The effectiveness of PSB activity in altering this form can be enhanced through carriers that are able to maintain their viability and activity in the soil. This study investigates the use of marginal land treated with phosphate solubilizing bacteria (PSB) incorporated with carrier materials to addressing the demand for sweet corn. PSB application followed a Randomized Block Design (RBD) involving the treatments as follows: control (T0), 150 kg Super Phosphate-36 (SP-36) per hectare (T1), PSB B5(6) + shrimp shells + 75 kg SP-36 per hectare (T2), PSB B1(17) + shrimp shells + 75 kg SP-36 per hectare (T3), PSB B5(6) + husk charcoal + 75 kg SP-36 per hectare (T4) and PSB B1(17) + husk charcoal + 75 kg SP-36 per hectare (T5). The results yield the optimum outcome associated with T2 by plant height (±70.25 cm), number of leaves (±8.97 pieces) and roots (±41 cm), root length (±31.10 cm) and volume (±14.05 ml), plant fresh (±53.72 gr) and dry weight (±28.01 gr), cob weight with husk (± 23.68) and without husk (±14.67 gr), cob length with husk (±12.88 cm) and without husk (±7.38 cm), cob diameter with husk (±22.76 cm) and without husk (±16.67 cm). T2 can reduce the use of inorganic phosphorus fertilizer up to 50% and increase production by approximately 7 times better than control.
