“…Yield of kalmi ranked in the order of T3>T6> T2>T5>T1> T4> T0. It appeared that maximum plant height, green weight and dry weight were attained with the highest dose of vermicompost application which was similar to the result reported by Atarzadeh et al (9) and Karmakar et al (10) .…”

An incubation study was conducted to find out the best mixing ratio of acid and calcareous soil (maintaining 70% moisture) for pot experiment. Depending on various physico-chemical properties mixed soil 1 : 1 (i.e. acid : calcareous) was selected for pot experiment. The pot experiment was carried out to observe the effects of vermicompost and compost on soil properties and growth and yield of Kalmi (Ipomoea aquatica Forsk.). This experiment included seven treatments with three replications including control. Treatment variables were T0 (control), T1 (4 t/ha vermicompost), T2 (8 t/ha vermicompost), T3 (12 t/ha vermicompost), T4 (4 t/ha compost), T5 (8 t/ha compost) and T6 (12 t/ha compost). All the treatments had significant positive effects over control on growth and yield of kalmi. The highest growth and yield were recorded with T3 (12 t/ha vermicompost) treatment. In case of, macro and micronutrient uptake treatment T3 (12 t/ha vermicompost) performed best followed by T6 (12 t/ha compost) over T0 (control). However, in post-harvest soil except soil reaction (pH); electrical conductivity (EC), organic carbon (OC), available N, P, K, S, Ca, Mg, Na, Fe and Zn significantly increased for T3 (12 t ha-1 vermicompost) than T1, T2, T4, T5, T6 and T0.

“…Alidadi et al [35] experimented with the application of vermicompost and cow dung on tomato plants and concluded that the vermicompost enriches the soil with essential nutrients. Similar results were found by Karmakar et al [36] , while experimenting on rice plant. According to Fulhage [37] , organic manure consists of the three major plant nutrients, nitrogen, phosphorus and potassium (NPK), and the essential nutrients such as Ca, Mg, S, Zn, B, Cu, Mn etc.…”

Incessant application of chemical fertilizers to the agricultural fields may alter the composition and activities of soil microbiota. Thus, the shift of cultivation practices from chemical to organic is considered to be the need of the hour in order to maintain soil health. A study was conducted in the agricultural fields of the University of Burdwan, India to observe the impact of organic manure on rhizosphere bacterial community. The experiments were conducted on maize plants, supplemented with the recommended dose of chemical fertilizer and organic manure (vermicompost and cow dung mixture). Corresponding changes in the plant phenological events and soil health in terms of soil physico-chemical factors and rhizosphere bacterial groups up to the level of CFU g-1× 105 dry soil were noted.The results showed a significant increase in population of nitrifying bacteria, asymbiotic nitrogen-fixing bacteria and protein hydrolysing bacteria in the organically treated plots. Moreover, the organic manure increases the bacterial population of rhizosphere, which in turn has a positive impact on maize growth and yield. The growth of the three groups of bacteria was attributed to the type of organic manure supplied to the agricultural fields.In addition, strong correlation was observed between Zn and protein hydrolysing bacteria. The soil organic carbon and available nitrogen were strongly correlated with nitrifying, fat solubilizing and phosphate solubilizing groups of bacteria.

“…The vermicompost increases the yield of rice and thus can be a substitute to chemical fertilizer to some extent (Sharma et al, 2008). It has also been found that in case of rice and lentil the application of vermicompost showed better result in terms of improving soil physical and chemical properties and increased grain yield and productivity in comparison to chemical fertilizers (Karmakar et al, 2015). A significant increase and the maximum dry matter, number of pods, pod yield (g) and seed yield (g) per plant of black gram was observed when vermicompost incorporated with the PSB seed inoculation (Kadam et al, 2014).…”

Growth attributes of Vigna mungo and Vigna radiata crop influenced by level and type of fertilizers. The present study was carried out to evaluate and compare the effects of organic (vermicompost) and inorganic (urea) fertilizers on the germination percentage and seedling growth of V. radiata (Green gram) and V. mungo (Black gram). Fresh weight and dry weight of tested plant samples at 10th days of growth stage were also determined. Vermicompost was used as organic fertilizer and urea as inorganic fertilizer. Experimental results showed that vermicompost and urea both has positive effect on seedling growth parameters of V. mungo and V. radiata [average root length (6.1cm and 6.7cm)] , shoot length (6.5cm and 8.3cm), leaf area (312.2 sq.cm and 334.1 sq.cm] as compared to control set [average root length (4.4cm and 4.3cm)] , shoot length (6cm and 5.9cm), leaf area (282.7 sq.cm and 305.5 sq.cm). But urea exerts negative effect on seed germination percentage in V. mungo and V. radiata (58% and 50%) as compared to control (77%). Vermicompost exhibited better result in above parameters in comparison to urea. V. mungo showed increased value in comparison considering V. radiata in case of organic, inorganic fertilizer treated as well as control sets. As composition of locally available fertilizers is unknown, the application of these fertilizers for improving germination percentage and growth parameters of tested crop need to be evaluated. Present work may provide the suggestive approach for usage of these tested fertilizers in field level trial.
