Abstract

Pesticides are widely used in agriculture, including on peat soil. The objective of this study was to analyze the effect of the application of paraquat, difenoconazole, and butylphenyl methylcarbamate (BPMC) on CO2 emissions and concentrations of phenolic acids in a peat soil. Peat soil sample was taken in District of Pulang Pisau, Central Kalimantan. The peat soil was applied with 1.89 mg kg-1 paraquat, 1.72 mg kg-1 difenoconazole and 1.65 mg kg-1 butylphenyl methylcarbamate (BPMC), then the soil was incubated for 1, 2, 4 , 5, 7, 10, 14, 21, 26 and 30 days. The results showed that the application of pesticides on peat soil increased CO2emission, and decreased CH4 emission and phenolic acid concentrations up to 30 days of incubation. The CO2 emmisions were derived from C of degraded pesticides and from C of phenolic acids, although the oxidation reaction was not accompanied by the change of soil pH. Keyword: CO2 emission, phenolic acids, butylphenyl methylcarbamate (BPMC), difenoconazole, paraquat, peat soil

Abstract

Pineapple is a leading commodity worldwide and can grow in a variety of mineral and organic soils. Excessive use of inorganic fertilizers has a detrimental impact on soil and crop health. Biofertilizers contain beneficial microorganisms that can enhance soil fertility, improve soil health, and promote sustainable crop production. This study aimed to investigate the crucial role of biofertilizers and mycorrhizae in promoting the vegetative growth of pineapple in acidic soils. The experiment was conducted using a completely randomized design with nine treatment levels and five replications. The results showed that the mycorrhizae applied at 5 g per plant, combined with full doses of chemical fertilizer (0.5 g ZA, 2 g DAP, and 2 g KCl per plant), produced the highest mycorrhizal colonization in treatment P4. Meanwhile, Provibio® biofertilizer at 5 mL per plant (diluted in 0.5 L water), mycorrhizae at 2.5 g per plant, and half doses of chemical fertilizer (0.25 g ZA, 1 g DAP, and 1 g KCl per plant (P8), improved vegetative growth and soil properties (pH, organic C, and total N) and supported the highest microbial population in the rhizosphere (26.05 × 10⁴ CFU.g-1 soil). This study demonstrated that the combined application of biofertilizers and mycorrhizae in moderate doses is more effective than full single-dose applications, leading to healthier soils and stronger vegetative growth of pineapple in acidic soils.

Abstract

Potensi Pupuk Hayati Mikoriza pada Bawang Daun (Allium Fistulosum L.) di Andosol Wonoboyo, Temanggung - Jawa Tengah. Bawang daun (Allium fistulosum L.) merupakan komoditas bernilai ekonomi tinggi dengan potensi ekspor, terutama ke pasar Asia Timur. Namun, budidayanya pada tanah andosol menghadapi tantangan berupa rendahnya ketersediaan fosfor akibat fiksasi oleh mineral tanah dan sistem perakaran tanaman yang dangkal. Penelitian ini bertujuan menganalisis aplikasi pupuk hayati mikoriza dan pupuk P terhadap pertumbuhan dan produktivitas tanaman bawang daun (Allium fistulosum L.) yang ditanam pada andosol di Kec. Wonoboyo, Temanggung, serta mengevaluasi perubahan kandungan hara NPK tanah, tingkat infeksi mikoriza pada akar tanaman, juga jumlah sporanya. Penelitian dirancang menggunakan Rancangan Acak Kelompok faktorial dua faktor: dosis mikoriza (0 dan 500 kg/ha) dan pupuk P (0 dan 200 kg/ha). Hasil menunjukkan bahwa tinggi tanaman pada 12 dan 13 MST berbeda nyata antar perlakuan, di mana perlakuan mikoriza tanpa pupuk P (M1P0) menghasilkan tinggi tanaman secara signifikan lebih tinggi dibanding kontrol dan kombinasi M1P1. Parameter kimia tanah setelah penanaman dan serapan hara NPK tanaman juga menunjukkan tidak adanya perbedaan signifikan antar perlakuan. Perlakuan M1P0 memberikan respon terbaik terhadap pertumbuhan dan produktivitas tanaman, serta menghasilkan jumlah spora mikoriza dan tingkat infeksi akar tertinggi dengan genus spora dominan adalah Glomus.

Abstract

Kabupaten Bandung memiliki ketinggian tempat antara 675 mdpl – 2,100 mdpl dengan suhu udara berkisar 14oC sampai dengan 30oC. Perbedaan ketinggian tempat dapat menimbulkan perbedaan iklim dan cuaca sehingga dapat mempengaruhi transformasi hara dan populasi mikrob di dalam tanah. Penelitian ini bertujuan untuk mengetahui korelasi sifat biologi dan kimia tanah, serta kaitannya antara sifat kimia dan fisika tanah pada berbagai ketinggian tempat di Bandung, Jawa barat. Pengambilan sampel tanah menggunakan metode Purposive Random Sampling dengan 5 kali ulangan. Sampel tanah terganggu diambil pada kedalaman 0-20 cm sebanyak ±1 kg, sedangkan contoh tanah utuh diambil menggunakan ring sampler. Pengambilan sampel tanah meliputi empat ketinggian tempat yaitu ketinggian 600 mdpl penggunaan lahan tanaman kol, ketinggian 1000 dan 1200 mdpl penggunaan lahan tanaman selada, serta ketinggian 1400 mdpl penggunaan lahan perkebunan kopi. Hasil analisis menunjukkan bahwa pada ketinggian 1000 mdpl populasi bakteri pelarut fosfat (BPF) dapat tumbuh optimum sebesar 93.6 x 103 CFU g-1 dengan pH tanah agak masam, P-Total sangat tinggi, dan P-Tersedia sedang. Populasi fungi dapat tumbuh optimum sampai ketinggian 1200 mdpl. Total populasi fungi berkorelasi tinggi dengan unsur hara P-Total dan N-Total di dalam tanah. Respirasi tanah berkorelasi positif dengan semua parameter yang berhubungan dengan sifat kimia tanah. Nilai bobot isi terendah pada ketinggian 1200 mdpl bersesuaian dengan nilai C-organik dan porositas tertinggi pada ketinggian tersebut.

Abstract

The spice and seasoning industry produce sludge waste that has the potential to pollute the environment if not managed properly. This waste contains nutrients and organic matter, making it a potential soil conditioner for sweet corn cultivation; however, its use must be combined with other materials such as rice husk charcoal and compost. This study aims to determine the effectiveness of combining sludge, compost, husk charcoal, and NPK fertilizer on the growth and productivity of sweet corn. This study was conducted at the Cikabayan Experimental Farm using a Randomized Block Design (RBD) with five levels of sludge application: (1) 100% sludge (S1H2), (2) 75% sludge (S2H2), (3) 50% sludge (S3H2), all treatments were combined with husk charcoal (75%), compost (30%), NPK fertilizer (75%), urea (100%), (4) PB (NPK 100%), and (5) Control (no treatment). Each treatment was repeated three times, resulting in 15 experimental units. The results showed that the S2H2 treatment yielded the best results for all plant growth parameters, such as plant height, stem diameter, and all generative parameters. The S1H2 combination yielded the best results for soil chemical and biological characteristics, including pH, organic carbon, total nitrogen, total microbes, and total fungi. The S1H2 combination also yielded the best results for corn plant productivity at 5.30 tons/ha. The combination of organic matter and NPK fertilizer application is highly efficient as it reduces NPK fertilizer use by 25%.

Abstract

Consumption of sweet corn has increased from 2021 to 2024. To meet the growing market demand, sweet corn production must be carried out in a sustainable, economical, efficient, and environmentally friendly manner. The use of a combination of sludge, rice husk charcoal, compost, and inorganic fertilizer was tested to enhance corn plant growth and productivity. The study was conducted at the Cikabayan Experimental Farm, IPB University, using a Randomized Complete Block Design (RCBD) with five treatment levels and three replications. The results showed that treatment S2H1 (75% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) exhibited the best vegetative and generative growth (stem diameter, number of leaves, ear length, biomass weight per plot, and ear weight per plot). The S1H1 treatment (100% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) showed improved biological and chemical soil quality (pH, organic carbon, total nitrogen, total phosphorus, and base saturation). All treatments resulted in an R/C ratio above 1, indicating economically viable potential. The results indicate demonstrate that the combined use of sludge and organic materials allows NPK fertilizer inputs to be reduced by 25%, supporting sustainable agriculture.
