Present investigations were carried out during 2006-2007 at University Guyana, Georgetown focusing on recycling organic waste using vermitechnology and use of vermicompost and vermiwash obtained from the vermitech in varied combinations for exploring the effect on soil and productivity of Okra (Abelmoschus esculentus) in Guyana. The soil quality was monitored during the experiment along with plant growth parameters of Okra. The study revealed that combination organic fertilizers vermicompost and vermiwash combination [VW+VC] compared with control [CON] and chemical fertilizers [CHM], had great influence on plant growth parameters. The average yield of Okra during trial showed a significantly greater response in VW+VC compared with the control by 64.27%. The fruits have a greater percentage of fats and protein content in VW+VC when compared with those grown with chemical fertilizers by 23.86% and 19.86%, respectively. The combination treatment [VW+VC] also have a significant
