Agronomic impact of earthworms, cow dung compost, vermicompost and chemical fertilisers on growth and yield of brinjal ( Solanum melongena )
The pot experiment was conducted to assess the impact of live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertilisers and control (without fertiliser) on growth and yield of brinjal (S. melongena). Growth and yield parameters were significantly superior in the pots treated with live earthworms as compared to other fertiliser inputs at 5% level. The plant height was recorded 71.12 cm, maximum fruit weight 900 g, time taken in budding and flowering 32 and 39 days, consecutively and number of fruits 100 in live earthworm + cattle dung treated plants. Vermicompost treated plants followed the results. It was also an important observation that very mild disease appeared in plants treated with live earthworms as live earthworms are ‘friend of farmer’, which can improve soil fertility if present consistently in farm soil.
