Water Holding

In this study, an analysis of organic fertilizer of an agro-waste (Sesame straw) plus cow dung was carried out using an epigeic earthworm species Eisenia fetida and Perionyx sansibaricus. Sesame straw is abundantly produced after each harvesting of the crop in Kharif season in arid region of tropical India. The compost produced in presence and absence of earthworm exhibit significant (P<0.001) and non-significant (P>0.05) changes in physicochemical properties respectively. In control bedding, the values of water holding capacity enhanced significantly (P<0.05) by 1.28 fold, while organic carbon and C/N ratio decreased significantly (P<0.05) by 19.93% and 31.25% respectively after 60 days of composting.Working of E. fetida in the bedding material showed significant (P<0.001) difference in the level of pH, electrical conductivity, water holding capacity, organic carbon, total nitrogen, C/N ratio, available phosphorous and available potassium. After 60 days of working of P. sansibaricus, these physicochemical properties of the bedding substrate also changed significantly (P<0.001). Analysis of vermibed showed a gradual increase in electrical conductivity, water holding capacity, total nitrogen, available phosphorus and available potassium by 1.51, 1.86, 1.95, 1.78 and 1.75 fold respectively. While the values of pH, organic carbon and C/N ratio declined by 9.30%, 41.80% and 71.48% respectively within 60 days of decomposition. Thus, E. fetida and P. sansibaricus can be applied for production of organic fertilizer of sesame chaff plus cow dung to fulfill the requirement of bio-fertilizers for organic farming and agro-waste management in arid environment.

Waste Degradation

The current study was carried out for the purpose of comparative evaluation of vegetable market waste degradation potential of three earthworm species (Eisenia fetida, Perionyx excavatus and Eudrilus eugeniae). The vegetable waste used as substrate in this study was collected from Mission Chariali vegetable market in Tezpur, Assam, India. Non-biodegradable materials such as polythenes, plastic etc. were segregated and organic waste was sun-dried. Cow dung was mixed with the substrate in 1:3 proportion and subjected to vermicomposting with three earthworms species separately. The data on physicochemical properties of the compost bed along with earthworm activity were collected every 10 days interval. The experiment was continued until 70 days. Analysis of the data indicated that E. fetida posed maximal nutrient mineralization and reduction in C:N ratio when compared with the data of day 0 with of day 70. Also, the values of vermicomposting coefficient were maximum for E. fetida. Moreover, the mean individual weight of E. fetida was also maximum during the decomposition period. Although Eu. eugeniae increased in total biomass much more rapidly than E. fetida, nevertheless, the cocoon production rate was greatest (78.67) in case of E. fetida, indicating the differential resource allocation with trade-off between sex alloca-tion and growth by Eu. eugeniae in a non-conducive environment during its life cycle. Overall, the results indicate suitability of E. fetida for vegetable waste degradation.

Vermicomposting is an ecofriendly technology to convert organic waste into organic fertilizer. An epigenic species Eisenia fetida was used for the biotransformation of the banana pseudostem scutchers and cow dung into the vermicompost. Three different combinations of the banana pseudostem scutcher and cow dung were evaluated in the vermicomposting process. The change in the physicochemical parameters were examined by the standard method at the end of the vermicomposting. The results showed that earthworms increased the EC and NPK content while total carbon, pH and C:N ratio was reduced significantly in vermicompost of banana pseudostem scutchers. The maximum significant change in NPK content and reduction of total carbon and C:N ratio was found in the mixture of (75% banana pseudostem scutcher + 25% cow dung). The highest growth and reproduction rate was also present in the T2 treatment. The seed germination test was performed to evaluate the maturity of the vermicompost. The prepared vermicompost shows the significant effect on the growth of the Vigna radiata. The germination of the Vigna radiata is comparatively higher in vermicompost of the T2 treatment. It is evident from the results that the banana pseudostem scutcher and cow dung are good substrates for the vermicomposting and Eisenia fetida able to convert this organic waste into the stable nutrient rich product. This nutrient rich vermicompost has no phytotoxicity and the ratio of carbon/nitrogen below 15 which indicates the acceptable maturity and it can be utilize as organic fertilizer.

Fly ash is an amorphous ferroalumino silicate, an important solid waste around thermal power plants. It creates problems leading to environmental degradation due to improper utilization or disposal. However, fly ash is a useful ameliorant that may improve the physical, chemical and biological properties of soils and is a source of readily available plant macro and micronutrients when it is used with biosolids. Supply of nutrients from fly ash with biosolids may enhance their agricultural use. The growth and reproduction ofEisenia fetidawas studied during vermicomposting of fly ash with cowdung and pressmud in four different proportions (T1,T2,T3& T4) and one controli.e.,cow dung and pressmud alone. The growth, cocoon and hatchlings production were observed at the interval of 15 days over a period of 60 days. The maximum worm growth and reproduction was observed in bedding material alone. Next to that the T1was observed as the best mixture for vermiculture.

The present work has assessed sustainable vermiconversion of aquatic weed water hyacinth (Eichornia crassipes). The garden soil, water hyacinth and cow dung were taken in the following the combinations of 1: 2 : 1, 2: 1: 1 and 1 : 1: 2. Two species of earthworms Eudrilus eugeniae and Eisenia fetida was used for the experiment. The total nitrogen (0.18% in control and 1.68% in earthworm treated) and phosphate (0.63 % in control and 1.64 % in earthworm treated) levels were increased and toxic heavy metals zinc (7.66 ppm in control and 2.58 ppm in earthworm treated) and copper (6.68 ppm in control and 1.15 ppm in earthworm treated) were significantly decreased. The earthworm enriches the compost with various nutrients for plant and microbial growth. Plant growth studies were conducted in all the combination of water hyacinth, maximum growth of root length (8.9cm and 7.2 in control) and shoot length (21.6cm and 16.2 in control) observed compare to control. Gut microbial analysis revealed that Bacillus cereus, Micrococcus luteus were predominantly present in the earthworm. The study recommended that the aquatic weed compost was suitable of agricultural usage.

Rolling Quality

Mechanical transplanted seedling must meet the requirements of standard seedling block with uniform distribution of seedlings and inter-twisting roots for rolling. This study was conducted to identify the effect of growing media on mat type seedling raised for mechanical transplanting at Bangladesh Rice Research Institute (BRRI), Gazipur during the period of 2012–2014 covering two dry and cold seasons (Boro) and one wet season (Aman). Seedling were raised on plastic tray using sandy loam and clay loam soil mixed with decomposed cow-dung, mustard cake, rice straw organic fertilizer, rice bran, poultry litter and vermicompost at the rate of 0.0, 10, 20, 30 and 40%. Rolling quality of the seedling mat decreased and seedling height increased with the increased of mixing rate of organic fertilizer except rice bran and mustard cake. Averaged across three seasons, 10 to 30% cow-dung, rice straw organic fertilizer, vermicompost, 10% poultry litter and 20 to 30% rice bran with both types of soil was found suitable for seedling mat and seedling height. However, seedling varied among the organic fertilizers with both types of soil in the order of cow-dung &gt; rice bran &gt; vermicompost &gt; poultry liter &gt; rice straw organic fertilizer &gt; mustard cake. Clay loam soil showed better performance on rolling quality over sandy loam soil.
