Vermiwash – Liquid Fertilizer Growth enzymes such as nitrogen, phosphorus.

Zinc shed was constructed above the units for shade.

Each of vermicomposting units 1, 2, and 3 comprised of several layers. The first layer starting from the bottom was packed with inches of pebbles and broken bricks, the second layer had sand, the third had 3 inches of soil. In the fourth layer, cattle dung was added, and here, the earthworms were inoculated, — earthworms per square meter of vermibed.

This was followed by a fifth layer of the predigested biodung organic waste.

The final layer acted as a mulch to prevent evaporation. This comprised of grass and dry leaves. The surfaces of the entire vermin pits were covered with tarpaulin, which were kept moist by spraying water daily.

When all the organic matter was converted to vermicompost in 60 days, it was harvested. Watering was stopped for a week so that the earth worms can move down. The vermi compost after harvested was sieved through a 3 mm sieve. In order to assess the physicochemical changes during the process, samples were taken from each unit every 10—12 days after the predigested matter was added. The physicochemical analysis of vermicompost and raw organic matter was carried out according to standard guidelines [ 12 ].

The samples were then taken and placed to air-dry and then ground for chemical analysis, together with the raw materials water hyacinth, grass, and a mixture of the two using standard procedure for the following: pH, EC, organic carbon, total kjeldahl nitrogen, available phosphate, and potash.

This is due to greater earthworm activity in T3 and their preferred palatability of mixed organic waste during the processes of vermicomposting. The mass of the organic material transferred to vermitech unit differed significantly from the mass of vermicompost harvested. The ingested organic material is macerated mixed with ingested soil material passed through the gut and is excreted as casts, with most of it very little changed chemically, but finely ground [ 2 — 4 , 9 ].

Table 1: Harvest data vermicompost. Partial biodung composting in T2 and T3 was carried out for the period of 3 weeks and transferred to respective vermicomposting units, whereas in T1 it was continued to 6 weeks. The temperature study showed that there were two-peak rise of temperature during partial biodung composting in T1 whereas single peak in T2 and T3 Figure 1.

The partial biodung compost obtained served as a good organic material for the earthworms to recycle and produce vermicompost. The temperature increase brings about killing of harmful microbes. The process of biodung composting involves partially aerobic and partially anaerobic process. This reduces the bulk of organic waste to one-third of the volume. The cattle dung solution serves the purpose of providing inoculum of microbes which carry out degradation of organic waste.

During the process of biodung composting, mesophilic flora predominates with their metabolic activity resulting in the increase in temperature of the organic waste. When the temperature falls, mesophilics become active again.

The changes in the microflora like bacteria, actinomycetes, and fungi during composting have been well studied [ 1 , 4 , 13 , 14 ]. Temperature also observed during the process of vermicomposting in the three vermicomposting units was recorded to be The initial materials, water hyacinth T2 , mixture of water hyacinth and grass T3 , were initially at a neutral pH, with the exception of grass T1 which was extremely mildly acidic, when they were added to the vermicompost units Figure 3.

The pH for all fluctuated between 5 and 8 until it was almost neutral on the day 60, when the compost was harvested. In T3, the percentage change in pH is minimal due to the moisture content of the water hyacinth; thus, the water released tends to neutralize the pH of the vermicompost. Generally in all the units, there was a temporary rise in pH.

Thus, the factors or physiological changes that affect growth rates could result in differences in the C:N:P ratio of biomass and cellular allocation [21].

The combined use of biological and organic amendments may differentially affect a crop with respect to nutrient-use efficiency and C:N:P stoichiometry, thus, affecting the potential benefits and limitations. For instance, the excessive use of organic sources of P can result in the suppression of the AMF community [22] , thereby highlighting the significance of careful nutrient budgeting for optimizing, rather than maximizing, soil fertility. Crop management involves a range of practices that can affect AMF associations directly e.

The organic sources of nutrients e.

However, the overuse of organic amendments, especially those high in P, such as chicken manure, may have a negative influence on AMF, and the precise effect of the organic amendments has been shown to be variable i. Therefore, the role and extent of the effects of a combination of organic and biological amendments on crops should be investigated to obtain more precise data before such practices are implemented in crop fields.

Furthermore, it is imperative to determine the extent to which organic amendments affect the response of a crop to different AMF species. The present study was undertaken with the objective of determining the influence of a VW foliar spray on mycorrhizal growth dependency and nutrient stoichiometry of bhut jolokia Capsicum assamicum inoculated using two different AMF, in acidic soil under pot conditions.

Bhut jolokia is a highly pungent chili species native to the northeastern region of India and has tremendous ethnopharmacological potential [25]. Pabohi, District Sonitpur, Assam, India were used in the pot experiment.

The pure inocula of two AMF i. The AMF bulk inoculum preparation was conducted in a naturally ventilated greenhouse by sowing surface-sterilized maize Zea mays L. The substrate containing the spores and root pieces served as the stock culture for AMF inoculum. The VW was prepared from air-dried mixed waste i. In brief, a tap was fixed on the lower side of the container.These nutrients are stored in the humic acid in a form readily available to plants, and are released when the plants require them.

In T1 and T2, there was a negative percent change which was probably as a result of microbial utilization. The substrate containing the spores and root pieces served as the stock culture for AMF inoculum.

The first layer starting from the bottom was packed with inches of pebbles and broken bricks, the second layer had sand, the third had 3 inches of soil.

Worms leave behind while reducing the household wastes turn into a good source of manure for plants the excreta. UN has also endorsed it. This is not surprising, considering that earthworms are a natural source of nutrition for birds and other animals in the wild.
