Effect of vermiwash and vermicompost on soil parameters and productivity of okra (Abelmoschus esculentus) in Guyana

Guyana is among many countries to adopt and practice organic agriculture; however, this is done on a small scale. There are also problems in disposal of organic waste. The present work was carried out during the year 2006–2007 at University of Guyana, Georgetown focusing on recycling organic waste using vermitechnology and use of vermicompost and vermiwash obtained from the vermitech for improvement of soil health and enhanced productivity of okra (Abelmoschus esculentus). Combination of organic fertilizers (vermicompost + vermiwash) had great influence on the nutritional value of the fruits. The fruits had greater percentage of fat and protein compared to those grown with chemical fertilizers. The vermiwash and vermicompost combination also had significant influence on the biochemical characteristics of soil with marked improvement in micronutrient contents.
