Abstract
Vermicompost is one of the best organic fertilizers reported to contain a number of mineral nutrients, soil enzymes and microbes and also going to improve seed germination, seedling vigor and plant productivity rather than inorganic mineral nutrients. The present study was undertaken to know the influence of different vermicompost produced by the epigeic earthworm, Eisenia fetida out of different organic wastes (FAW, PW, CRW, LGW and CM) amended with soil along with pure soil (PS) as control on germination and seedling growth such as root length, shoot length, number of leaves and leaflets of Green gram (Vigna radiata) at 10, 20, 30 days’ time intervals maintained at uncontrolled environmental conditions.
The findings of the present research tells that the duration for seed germination in all the experimental pots was 5-6 days at 10, 20 and 30 days’ time intervals. The root length of Green gram was higher in soils treated with vermicompost of CRW, CRW, CRW followed by CM, LGW, LGW; PS, PW, PS ; PW, PS, PW ;LGW, CM, CM and least in FAW, FAW, FAW at 10, 20, and 30 days’ time intervals respectively. The shoot length was higher in vermicompost of LGW and least in Pure soil at 10, 20 and 30 days’ time intervals among VC of different organic wastes and PS. Likewise, number of leaves and leaflets were also observed more in VC of LGW, CRW, CM followed by FAW, PW and least in PS among all the VC treated soils and PS. There is significant variation was observed among and between different VC treated soils and soil alone PS except between few parameters at 10, 20 and 30 days’ time intervals.
On the basis of the above results, it can be concluded that the vermicompost produced by the epigeic earthworm, E. fetida out of different organic wastes have all the macro and micronutrients for better seedling growth and it can be used as an alternative organic biofertilizers so that it can reduce the dependance of chemical fertilizers
