Abstract : This can be used as a supplement to suit the nutrient needs of local plants like cabbage. In light of the harmful environmental repercussions of improper swine blood waste disposal and the use of chemical fertilizers. Pots were placed and positioned inside the safe framework, and each pot was filled with 15 kg of soil-1. The five treatments were assigned as follows: T1-control; T2-60 grams of BM; T3-120 grams of BM; T4-180 grams of BM; and T5-240 grams in each of the 15 kg of soil-1 pots. This research looked into the impacts of blood meal (BM) on the chemical characteristics (pH, OM%, N%, avail. phosphorus, and exch. potassium) of degraded upland soil, as well as the effects on cabbage production potential. The results demonstrate that all of the treatments have a pH range in the pH soils that were fairly acidic. Furthermore, it has a moderate organic matter (OM) percentage of at least 2% and the lowest nitrogen (N) percentage (< 0.15), both of which were sufficient to maintain stable N availability to plants in the range of 0.11-0.14. For most crops, a very low phosphorus content of less than < 25 ppm was predetermined as a critical deficiency level. The potassium level was also at an all-time low of <150. Finally, based on the marketable yield calculated from the computation, T3 was significantly (p< 0.05) affected as the best level of BM in the treatment, whereas T2 had a similar effect. Cabbage has created a larger ball of T3 as a result of the higher temperatures, regardless of whether the heads were properly formed or merely sparse..

Abstract : Permanently frequent utilization of fertilizer posed problems in soil fertility that hinder farmers’ crop production due to excessive soil erosion and rapid leaching of essential nutrients. It aimed to evaluate the effect of SRF-PB (Slow releases fertilize- Plastic bottles) on the chemical properties of soil and the yield potential of green bell pepper. It was assigned as chemical soil samples were organic matter (OM), pH, nitrogen (N), phosphorus (P2O5), and potassium (K2O). The experiment was laid out in RCBD with seven treatments and three replications, respectively. The results were collected T0-control, T1-water-soluble fertilizer application (WSF), T2-commercial controlled-release fertilizers (CRF); and SRF-PB of 25%, 50%, 75%, and 100% with T3-T6 holed portion in the treatments, respectively. The soil pH of treatments applied with control, commercial CRF, and SRF-PB technology ranges from medium acidic (T0 and T2 -T6) and slightly acidic (T1). OM content, on the other hand, was found to be low among the treatments (T0-T4 and T6) and desired with T5 of the percentage treatments. The N level suggests that all sites reach a relatively low range. The phosphorus was high in T1-T5, and sufficient in T0 and T6 observed treatments. The potassium was acceptable in decreasing T0 and T2, slowly increasing at high T6, and excessive in swiftly increasing T1 and T3-T5. In contrast, the significantly (p <0.05) highest yielding findings revealed that using T2 increased fertilizer efficiency, with T6 having a higher root density and a higher harvest yield. In terms of increasing green bell pepper yield, T6 might be a viable alternative to commercial T2..

Abstract : The export of raw commodities which have lower value has not been able to generate optimal profit for a country. As a major producer of various agricultural commodities, Indonesia is still experiencing the same issue, and with many advantages that can be gained from the export of processed products, various encouragements have emerged for downstream agricultural export products. This study aims to analyze the benefit comparison obtained between exporting processed products and their raw materials. Research is conducted using linkage analysis and multiplier analysis in the 2016 input-output table. The result shows that processed products tend to be able to spur production growth of the upstream sectors, while agricultural commodities could not. Meanwhile, only a few main raw commodities which able to drive downstream sector production. In general, increasing exports of processed agricultural products generate a greater impact on the creation of aggregate output and total labor income. However, this increase in exports of processed agricultural products needs to be supported by sufficient supply, product safety, and certification in order to gain high competitiveness and be accepted in the global market. Processed products namely processed tea, processed rubber, processed palm oil, processed coffee, processed coconut, as well as processed chocolate can be considered a priority for increasing Indonesian export due to the high output and income multiplier creation and the availability of materials..

Abstract : Earthworms are considered as biological indicators of soil fertility forms the major macro fauna of soil. DNA tag are done to identify individuals belonging to the same species, as well as to distinguish between individuals from different species. In the present work, the earthworm fauna was investigated from three Taluks namely, Somvarpet, Virajpet and Madikeri of Coorg, a district situated in the south western part of Karnataka, India. This is the first scientific report on the earthworm species of Coorg and the physio-chemical properties of their soil. The physio-chemical characteristics of the soil were examined and DNA barcoding technology was used to identify the taxonomic status of earthworms. A total of 38 earthworm samples were collected, 30 of which were amplified using mitochondrial Cytochrome Oxidase subunit1 (CO1) gene specific primers. The sequencing data was deposited into Genbank and assigned accession numbers (30 Accessions). The maximum likelihood technique was used to create the phylogenetic tree. Kimura's two-parameter model was used to calculate pairwise genetic distance. DNA barcoding results showed that Pontoscolex corethrurus was the most common earthworm species in Coorg. Progizzardus varadiamensis, Glyphidrilus annandalei, Amythas sp., Metaphire megascolidioides, Dichogaster bolaui and Acanthodrilidae sp were also observed. From the findings it is observed that the mean pH of Coorg soil was found to be 6.2 with an electrical conductivity of 0.28 dS/m. Coorg soil contains a moderate level of Organic Carbon (O.C) content with an average of 1.74%. Thus, the study included extensive descriptions of earthworm species, as well as their DNA barcodes and the physio chemical characteristics of their habitat, which help with future species identification..

Abstract : Cinnamomum balansae is an endemic species of Vietnam. The species has a high potential for poverty reduction because it contains essential oil of up to 170 US$/liter and has durable timber of up to 1,500 US$/m3. Six pot mediums were tested to evaluate their effects on the survival and growth of seedlings in the nursery stage. The survival rate, stump diameter, and height of seedlings were collected at 6 months of growth. The results indicated that pot mediums significantly affected the survival rate and growths of seedlings. The highest survival rate of 87.8% was recorded in pot medium of 98% forest soil collected from 0-30 cm soil layer and 2% NPK fertilizer (16% N: 16% P: 8% K) by volume (soil-NPK pots). While the lowest was found in the medium of 100% forest-soil pots (76.7%). The largest stump diameter and tallest seedling height were also found in soil-NPK pots with a mean stump diameter of 0.57 cm and seedling height of 50.8 cm. The smallest stump diameter (0.34 cm) and seedling height (34.9 cm) were also recorded in 100% forest-soil pots. It is concluded that fertilizer plays an important role in producing seedlings for C. balansae. Fertilizing NPK should be conducted to seedlings during the nursery stage..
