Planting shallots in Buahan Village is only carried out once a year, namely in July. The continuous use of synthetic fertilizers at high doses without being balanced with natural fertilizers has degraded the land so that soil fertility has decreased. The negative impact caused is a decrease in the yield of shallots. Quality organic fertilizers can overcome this problem. Organic vermicompost and biosllury fertilizers are quality organic fertilizers that can replace synthetic fertilizers to increase the growth and yield of shallots. The research objective was to determine the growth and yield of shallots by giving the type and dose of organic fertilizers outside the growing season. The research was conducted from March to July 2019 in Buahan Village, Kintamani District, Bangli Regency. The study used a simple randomized block design with one factor with 6 treatments, namely B0 (Without Organic Fertilizer), B1 (2000 kg / ha vermicompost); B2 (1000 L / ha biosllury) B3 (1000kg / ha vermicompost + 500 L / ha biosllury); B4 (4000 kg / ha vermicompost); B5 (2000 L / ha biosllry); B6 (2000kg / ha vermicompost + 1000 L / ha biosllury); B7 (4000 kg / ha vermicompost + 2000L biosllry) and B8 (5000 kg / ha vermicompost + 3000L / ha biosllury). The parameters observed were plant height, number of tillers, tuber wet weight per clump, harvest dry weight of tubers per clump and number of cloves per clump, soil pH, N-total (%), C-organic and total population of soil microorganisms. The results showed that the type and dose of organic fertilizer had a significant effect on all the meters observed. Treatment of 5000 kg / ha vermicompost + 3000L / ha biosllury gave the highest yield, namely 56.8 g per clump, 60% higher than the control 35.5 g per clump.

The low level of farms income from agricultural sector mainly happens in dry season had to inappropriate soil cultivation. The utilization of soil for brick ste manufacturing is one of this case. The excavation process occurs on top soil inflicting degradation of soil fertility. Soil in the impact of this condition has a problem in providing chemical element for the agriculture, especially the lack of N. One of alternative attempts to increase the soil fertility in providing N on formerly brick ste excavation-soil is by supplying Petroganik fertilizer and compost. Petroganik and compost is an organic fertilizer containing N, P, K, the other nutrient, similar to the other organic fertilizers. The aims of the research are to determine the effect Petroganik fertilizer and compost application on N uptake and toward the growth of corn on former brick ste excavation-soil, and to know the chosen dosage which is resulting in growth and N uptake of corn. Research used is Random Block Design with 9 treatment and 3 replication. Dosage of treatment T0 : Control, Petroganik (14, 17, 20, 23) t/ha and compost (14, 17, 20, 23) t/ha. Indicator plant was used Hybrid Corn BISI 2. The result of experiment showed that : 1. Significant effect in increasing uptake of N the corn. The treatment of Petroganik 17 t/ha (P2) increasing 145 % and compost 14 t/ha (P2) increasing 93.8 %, 2. Insignificant effect on plant growth (height, number of leaf) However, it gives significant effect on dry weight of the corn biomass. The treatment Petroganik 17 t/ha (P2), increases 101.45 %, 3. The application of Petroganik fertilizer is more effective in increasing the growth and N uptake of corn than that of compost since the application of 17 t/ha of Petroganik has already increased the N uptake and growth of corn .

AbstractThe biochemical composition of organic fertilizers largely determines their nutrient supply characteristics following soil application as well as their potential impact on soil microbial communities. Yet, limited information is available regarding the biochemical composition of organic fertilizers derived from different nutrient sources. Here, we qualitatively analyzed the presence and abundance of proteins, lipids, and metabolites in a liquid fish fertilizer (LFF) product and a type of granular organic fertilizer (GOF) commonly used in organic vegetable production, using liquid chromatography–tandem mass spectrometry (LC–MS/MS). Our results suggest that the presence and abundance of proteins, lipids, and metabolites differ greatly between GOF and LFF. The qualitative analysis shows LFF as a rich source of metabolites, while complex proteins and long-chain saturated fatty acids are dominant in GOF. The degree of biochemical composition complexity may help explain the varying impacts of different types of organic fertilizers on nutrient availability, soil health, and environmental quality.

<p class="Default">ABSTRACT</p><p class="Default">Organik matter has an important role in determining soil health of sugarcane, i.e. soil capacity to support sugarcane to produce sustainable high yield. Soil organic matter influences soil physical, chemical, and biological properties, so that a consequence of declining soil organic matter is poorer soil fertility and lower yield. This paper has an objective to elucidate the important role of organic matter on sustainable farming of sugarcane. The important role of organic matter in soil fertility has been known for a long time before Green Revolution concept was introduced. With more intensity in sugarcane farming and more increasing of sugar demand, application of organic fertilizer started to be substituted by chemical fertilizer. Using green manure and/or biofertilizer has a chance to be spread out to the farmers due to more practical and more efficient than solid organik fertilizer, such as dung manure or compost. Future research should be focusing on the efectivity of green manure and or biofertilzer sources in improving soil fertility and cane yield, minimizing soil pathogen, reducing soil erosion of sugar cane land monoculture, and improving awareness of farmers about soil degradation as consequences of sugarcane monoculture planting for years.</p><p class="Default">Keywords: Organic matter, sugarcane, soil health sustainable farming</p><p class="Default"> </p><p class="Default"><strong>Bahan Organik: Peranannya dalam Budidaya Tebu Berkelanjutan</strong></p><p class="Default">ABSTRAK</p><p class="Default">Bahan organik tanah berperan penting dalam menentukan kesehatan tanah tebu, yaitu kapasitas tanah yang dapat mendukung produksi tebu yang tinggi secara berkelanjutan.

Pentingnya peran bahan oganik tersebut sudah disadari dari dulu, sehingga sebelum revolusi hijau penggunaan pupuk organik sudah umum dilakukan petani. Dengan semakin intensifnya budidaya tebu dan semakin meningkatnya kebutuhan gula, pemanfaatan pupuk organik sudah jarang dilakukan. Diperlukan usaha untuk meningkatkan dan mempertahankan kadar bahan organik pada lahan tebu, antara lain berupa gerakan masal dalam bentuk gerakan nasional melalui program aplikasi bahan organik. Pemanfaatan pupuk hijau dan/atau pupuk hayati berpeluang untuk diterapkan karena lebih praktis dan efisien daripada penambahan pupuk organik padat. Penelitian ke depan perlu difokuskan untuk mengkaji jenis-jenis pupuk organik dan pupuk hayati yang efektif memperbaiki kesuburan, dalam menekan serangan penyakit, meminimalkan erosi pada lahan-lahan tebu monokultur, dan meningkatkan kesadaran petani tebu tentang terjadinya degradasi lahan akibat penanaman tebu yang terus menerus.</p><p class="Default">Kata kunci: Bahan organik, tebu, kesehatan tanah, budidaya berkelanjutan</p><p class="Default"> </p>

The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers.
