Abstract


The chief economic activity of Guyana is agriculture. In the agricultural industries, the use of fertilizers for crop cultivation has become very prevalent and this has decreased crop quality over the years. The use of fertilizers accounts for about 75% of crop cultivation and quantity has basically become the major concern rather than quality. The present research carried out during 2012-13, indicated that chemical fertilizers improve quantity but not quality while organic fertilizers maintain both quantity and good quality of crops. The physico-chemical analysis of vermiwash showed the necessary elements for plant growth are present in sufficient quantity. T8 (neem + rice straw + cattle dung) followed by T9 (neem+ rice straw+ bagasse+ cattle dung) and H (chemical treatment) were the most effective treatments in hydroponics compared to C (distilled water) and T1(cattle dung) that were minimally effective. This is substantiated by 2-factor ANOVA and composite index. Most plants grown using different vermiwash in hydroponics showed less moisture, better shoot and root growth, number of leaves, nodes and resistance to insect damage compared to plants grown with standardized hydroponic solution. Vermiwash obtained from vermitech units with combinations of organic matter generally produced better crops   compared to the chemical wash used for hydroponics.
