Growth Performance and Yield of Brassica rapa var. chinensis With Takakura and Conventional Compost
Full text linkComposted organic waste from food waste and plants is beneficial to enhance crop productivity and agricultural sustainability. Compost added to soil as a soil amendment is rich in a wide range of plant-available nutrients that could significantly enhance the plant growth and yield but there is no specification of different composting methods to produce compost as a soil amendment for crops. Thus, this study aims to evaluate the growth performance and yield of Brassica rapa var. chinensis (B. rapa) cultivated or growing in the medium (topsoil) incorporated with compost varied in composting methods. Additionally, the study also investigates the growth response of B. rapa when chemical fertilizer is added during cultivation from third week until harvest. Six treatments were applied, namely cultivation of B. rapa with topsoil only (C), topsoil with fertilizer (CF), Takakura compost amendment only (T), Takakura compost amendment with fertilizer (TF), conventional compost amendment only (M) and conventional compost amendment with fertilizer (MF). The results showed that after six (6) weeks of cultivation, the plant height averaged 20 cm with 18 leaves produced across compost amendment treatments, while the treatments with fertilizer with plant height averaged 25 cm with 21 leaves produced. The other growth parameters, namely fresh to dry weight ratio, root to shoot ratio, and light interception percentage, showed no significant differences at p ≤ 0.05 among all the compost amendment treatments (T, M, TF, and MF) while different with C and CF treatment. The leaf area and total yield of B. rapa show significant differences among compost amendment treatments, while the treatment with chemical fertilizer achieved the highest yield of 1173.4 cm2 in leaf area and 44.3 t/ha of total yield. From this study, applying different types of compost, either Takakura or conventional composting, positively affects the growth performance of B. rapa plants. Moreover, combining fertilizer and compost amendment during cultivation will promote the increment in B. rapa leaf area and yield

Full text linkEl objetivo de la investigación es determinar la eficiencia del compostaje tradicional,
Bocashi y Takakura en la degradación de residuos orgánicos en el distrito de
Chachapoyas, Amazonas. El tipo de la investigación es aplicada, con enfoque
cuantitativo y diseño experimental, para eso se realizan cinco tratamientos; T
(Tradicional) con una repetición, TK1, TK2, B1 Y B2, estos con 3 repeticiones cada
uno, por cada método se hizo dos dosis con diferentes componentes para la
preparación. Los resultados obtenidos, se basan en parámetros fisicoquímicos (N,
P, K, C.E., %H, T° y pH) donde el Takakura obtuvo el 63.3% de criterios
fisicoquímicos de calidad de compost; el tradicional cumplió el 58,67% y el método
Bocashi cumplió en su dosis 1 el 55% de los criterios y en su dosis 2, el 53%. En
los parámetros microbiológicos (Recuento de aerobios mesófilos, hongos y
levaduras) todos estuvieron dentro del rango establecido y por último, se calificó la
efectividad técnico económica de cada uno de los métodos, las dosis del Takakura
obtuvieron un 100% de eficiencia, el método Bocashi en sus dos dosis completaron
el 90.42% de eficiencia. Finalmente, el tradicional completo el 60% de eficiencia en
la degradación de residuos orgánicos
Perbedaan Pemberian Bioaktivator dalam Kompos Takakura terhadap Pertumbuhan Tanaman Tomat (Lycopersicum esculentum)
Full text linkIndonesia's population is increasing from year to year which has an impact on increasing the amount of waste and has a negative impact on public health and the environment. One of the proper waste handling methods is simple, practical, and efficient composting using the Takakura composting method. This study aims to determine the differences in stem height and number of leaves of tomato plants (Lycopersicum esculentum) between the control group and the treatment group with the addition of 4 bioactivators in Takakura compost. The research method uses an experimental design conducted in Banyuwangi during March-April 2022. Statistical analysis using T-test on data that is normally distributed and the Mann-Whitney test is used on data that is not normally distributed was carried out to determine differences in stem height and number of leaves of tomato plants (Lycopersicum esculentum). The results of this study showed that there was a difference (p value is 0.008 is less than 0.05) between the stem height of the tomato plants in the control and treatment groups with the addition of leachate activator compost, and there was no difference in the height of the tomato plants with the addition of EM4 bioactivator, BSF larvae, and drops. sugarcane. The results also showed no difference in the number of leaves from the addition of all bioactivators (EM4, BSF larvae, leachate, and molasses) in Takakura compost. It is recommended that further research be able to measure the C over N ratio during composting to determine the nutrient content in each activator during composting.Jumlah penduduk Indonesia semakin meningkat dari tahun ke tahun yang berdampak pada pertambahan jumlah sampah dan tentunya mengakibatkan dampak negatif terhadap kesehatan masyarakat serta lingkungan. Salah satu cara penanganan sampah yang tepat yakni pembuatan kompos sederhana, praktis, dan efisien dengan menggunakan metode komposting Takakura. Penelitian ini bertujuan untuk mengetahui perbedaan tinggi batang dan jumlah daun tanaman tomat (Lycopersicum esculentum) antara kelompok kontrol dan kelompok perlakuan dengan penambahan 4 bioaktivator di dalam kompos Takakura. Metode penelitian menggunakan desain eksperimental yang dilakukan di Banyuwangi selama bulan Maret-April 2022. Analisis statistik menggunakan Uji T pada data yang berdistribusi normal dan Uji Mann Whitney digunakan pada data yang tidak berdistribusi normal dilakukan untuk mengetahui perbedaan tinggi batang dan jumlah daun tanaman tomat (Lycopersicum esculentum). Hasil dari penelitian ini menunjukkan adanya perbedaan (p value sama dengan 0.008 kurang dari 0.05) antara tinggi batang tanaman tomat pada kelompok kontrol maupun kelompok perlakuan dengan penambahan kompos aktivator air lindi, dan tidak ada perbedaan tinggi tanaman tomat pada penambahan bioaktivator EM4, larva BSF, dan tetes tebu. Hasil penelitian juga menunjukkan tidak adanya perbedaan jumlah daun dari penambahan semua bioaktivator (EM4, larva BSF, air lindi, dan tetes tebu) pada kompos Takakura. Penelitian selanjutnya disarankan dapat melakukan pengukuran C dibagi N rasio saat pengomposan untuk mengetahui kandungan hara di setiap aktivator pada saat pengomposan

en las Pilas presentaron resultados similares, en general se ve que el periodo mesófilo
duró 5 días, el termófilo 25 días, el enfriamiento 15 días y 5 días de estabilización,
siendo en total de 50 días (1 mes y 20 días). Los resultados de las características

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
Full text linkIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
