Effect of vermicompost and vermiwash on the productivity of spinach (Spinacia oleracea), onion (Allium cepa) and potato (Solanum tuberosum).

摘要

Present investigations were carried out during 1998-2000 at Shivri farm of Uttar Pradesh Bhumi Sudhar Nigam, Lucknow, India, to study the effect of vermicompost and vermiwash in reclaimed sodic soils on the productivity of spinach (Spinacia oleracea), onion (Allium cepa) and potato (Solanum tuberosum). The soil quality was monitored during the experiment followed by productivity. Amongst the combinations of vermicompost @ 6 tonnes and vermiwash (different concentrations), there has been significant improvement in soil qualities in plots treated with vermicompost and vermiwash (1:10 v/v in water), vermicompost and vermiwash (natural) and vermicompost and vermiwash (1:5 v/v in water). The yield of spinach was significantly higher in plots treated with vermiwash (1:5 v/v in water). The yield of onion was significantly higher in plots treated with vermiwash (1:10 v/v in water), whereas the average weight of onion bulbs was significantly greater in plots amended with vermicompost and vermiwash (1:5 v/v in water). The yield of potato and the average weight of potato tubers were significantly higher in plots treated with vermicompost.
