“…Gradual increase in soil pH with increasing amounts of vermicompost (up to 30 tons ha -1 year -1 in T 4 ) during the present study corroborates with the findings of Gopinath et al (2008), Suthar (2009) and Lazcano and Dominguez (2010). Gradual increase in soil electrical conductivity (thereby indicating increase in rate of mineralization) with increasing concentrations of vermicompost as found in the present study was also reported by Klock (1997) and Atiyeh et al (2001). Increase in the electrical conductivity of field soils indicates increase in the rate of mineralization following application of vermicompost.…”

Purpose Rubber leaves are the abundant agro-waste and pineapple, the most economically important fruit crop in Tripura. So, in our present study, different amounts of rubber leaf vermicompost have been applied to the soils of pineapple plantation to determine their effects on earthworms-the soil ecosystem engineers, coupled with the vegetative growth and yield of pineapples. Methods During 30 months of field trial (2010-2012) in ICAR regional station, Lembucherra, West Tripura, the control plot (T 0 ) received no fertilizer, while experimental plots were fertilized with four different amounts of vermicompost viz. T 1 (5 tons ha -1 year -1 ), T 2 (10 tons ha -1 year -1 ), T 3 (20 tons ha -1 year -1 ) and T 4 (30 tons ha -1 year -1 ). Results A significant (p \ 0.05) but gradual increase in density (up to T 3 treatment) and biomass (up to T 4 treatment) of earthworms were recorded with the increasing amounts of vermicompost. During the second year, average length and width of leaves, number of leaves per plant, plant girth, fruit weight, fruit yield and fruiting percentage were highest in the T 3 plot compared to other treated plots and control. ConclusionThe present study reveals that crop yield is very much related to the particular concentration of vermicompost, beyond the level of which production declines and increase in vegetative growth, fruit weight and fruiting percentage of pineapple are strongly linked with the soil pH, av. P, av. K, clay content and the earthworm density of soils.

“…This characteristic hinders their use at high proportion as growth-media constituents. Nevertheless, satisfactory growth of several ornamental plants with different sensitivity to salts has been achieved using compost-containing substrates: Impatiens and Antirrhinum on biosolids and garden-waste compost (Klock, 1997); Calendula and Calceolaria on brewery and olive industry-waste composts (García-Gómez et al, 2002); Geranium, Petunia, Gerbera, and carnation on wine industry-waste compost (Carmona et al, 2012).…”

A comparative study on the suitability of one compost and two vermicomposts, obtained from the same batch of tomato-crop waste, as growth media for ornamental plant production was carried out. Each material was mixed with Sphagnum peat at 100 : 0, 75 : 25, 50 : 50, 25 : 75, and 0 : 100 (peat control) proportions by volume. Two ornamentals (Calendula officinalis, Viola cornuta) were sown and grown in the 13 substrates. Substrates were characterized physically and chemically. Seed germination, total leaf chlorophyll (SPAD units), plant growth, and plant nutrient concentrations were determined. The compost and the vermicomposts were markedly different from peat. Compost and the vermicomposts had greater bulk density and lower total porosity than peat. Compost had larger aeration and lower water-holding capacity than vermicomposts and peat. Compost and vermicomposts were alkaline (pH = 8.8 on average) whilst peat was acidic (pH = 5.9). Electrical conductivity was low in peat (0.23 dS m -1 ) and vermicomposts (0.65 dS m -1 ), and high in compost (2.85 dS m -1 ) due to the high concentrations of K + and SO 2À 4 . Mixing compost and vermicomposts with peat produced substrates with intermediate characteristics. Physical properties were within adequate range for all mixes except for the compost ones. pH was within adequate range only in pure peat, and salinity was extremely high in the compost mixes. Compost was phytotoxic, as shown by the strong reduction of seed germination, chlorophyll content, and plant growth of both ornamentals. Vermicomposts did not affect seed germination but reduced plant growth, though much less than compost. Mixing these materials with peat improved germination and growth. The diluted materials (compost at the 25 : 75 and vermicomposts at the 50 : 50 and 25 : 75 proportions) produced good-quality plants.

“…Despite developing a fine-textured root system, petunias grow prolifically and produce thousands of seeds per plant. In addition, petunia has been widely used as an indicator crop to evaluate heavy metal uptake from waste-based substrates (Burger et al, 1997;Klock, 1997;Bucher and Schenk, 2000).…”
