“…It is almost certain that VC improves the nutrient content of the soil or the container media to which it is applied [61][62][63][64][65]. Several other reports also suggest that the increase in the growth and yield of plants is a result of the increased nutrient levels in the VC amended soil/media [66][67][68][69][70][71][72][73][74][75].…”

Vermicomposting is a process in which earthworms are utilized to convert biodegradable organic waste into humus-like vermicast. Past work, mainly on vermicomposting of animal droppings, has shown that vermicompost is an excellent organic fertilizer and is also imbibed with pest-repellent properties. However, there is no clarity whether vermicomposts of organic wastes other than animal droppings are as plant-friendly as the manure-based vermicomposts are believed to be. It is also not clear as to whether the action of a vermicompost as a fertilizer depends on the species of plants being fertilized by it. This raises questions whether vermicomposts are beneficial (or harmful) at all levels of application or if there is a duality in their action which is a function of their rate of application. The present work is an attempt to seek answers to these questions. To that end, all hitherto published reports on the action of vermicomposts of different substrates on different species of plants have been assessed. The study reveals that, in general, vermicomposts of all animal/plant based organic wastes are highly potent fertilizers. They also possess some ability to repel plant pests. The factors that shape these properties have been assessed and the knowledge gaps that need to be bridged have been identified.

“…The highest biomass and seed yields were 570.14 and 169.36 g/m, respectively, were found to be related to well-watered plants and the application of VC, whereas the lowest ones (291.17 and 113.92 g/m) were obtained in severely stressed plants and without the use of fertilizers (control) (Figure 6). Cell growth is among the most key processes that are affected by water deficit due to lower turgor pressure (Das et al, 2017). When leaf size is reduced, the capacity to intercept light decreases, which subsequently decreases the total photosynthesis capacity (Das et al, 2017).…”

This study investigated the effect of organic fertilizers on vegetative growth and the physiological and antioxidant activity characteristics of thyme plants grown under stress. A factorial experiment was conducted according to randomized complete block design with 12 combinations and 3 replications in the 2018 growing season. The experiment factors were the implementation of organic fertilizers at 4 levels (vermicompost, manure compost, animal manure, and control) and irrigation regime at 3 levels (Irr1, Irr2, and Irr3, respectively, irrigation after 60, 90, and 120 mm evaporation from A pan). The results showed that With delayed irrigation, the chlorophyll a and b contents, total chlorophyll, and carotenoid decreased, while the application of low water stress enhanced the amount of oil and the oil yield with the respective highest values of 2.61% and 3.68 g/m under mild stress conditions. Nonetheless, higher values for the aforementioned properties were noted with the application of vermicompost. Water deficit decreased nutrient uptake (K, P, and N) and relative water content, biological yield, and seed yield of thyme, indicating that thyme was sensitive to drought, and organic fertilizers application improved nutrient uptake (K, P, and N) and relative water content, biological yield and seed yield of the plant within irrigation levels. The activities of catalase, superoxide dismutase and ascorbate peroxidase were reduced under organic fertilizers such as vermicompost and manure compost as compared with control under drought stress. The plants of thyme showed a good response to organic fertilizers under water deficit circumstances, with vermicompost being the most effective.

“…Besides, vermicompost also enhances health related secondary metabolites in plants (Das et al 2018). Application of vermicompost along with other organic amendments signi cantly improves the radical scavenging and antibacterial activity of plant's leaf (Das et al 2016). The environmental impact such as greenhouse gas emission like methane is signi cantly lower and negligible during vermicomposting as compare to traditional composting (Nigussie et al 2016).…”

Vermicomposting potential of waste biomass of potato crop that are generated at the time of harvesting was studied employing Eisenia fetida. The experiment was carried out in pots taking two treatments; in one only potato plant biomass (PPB) was taken as raw materials whereas in the other a mixture of PPB with cow dung was engaged in the proportion of 5:1. The vermicomposted materials showed a reduction in C/N ratio, humi cation index, enhancement in nutrients pro les, ash contents, nitrogen-xing, phosphate and potassium solubilizing bacterial population. The macronutrient enhancement in the vermicompost samples was recorded 3.8-4.4 fold for total N, 5-5.6 fold in available P, 1.6 fold in total K, 5.2-6.2 fold in total Ca and 1.6 fold in total Mg contents. The reduction in C/N was found in the rage of 92.5-94.4% in the vermicompost samples. The scanning electron microscope (SEM) images showed higher disintegration in the vermicompost products when compared with initial raw material and compost samples. Addition of cow dung signi cantly enhanced the quality and quantity of vermicompost nal products besides positively affecting the earthworm population and biomass by the end of 60 days of experimental trials.
