Effect of cultivation practices on nutritional composition of vegetables

The present investigation was carried out with the objectives to study the nutrient composition of vegetables grown under organic and inorganic conditions. The results of the present study revealed that inorganically grown vegetables had significantly higher moisture and crude protein per cent as compared to organically grown vegetables. Significant difference was observed in crude fiber content among all the organically grown and inorganically grown vegetables. All the vegetables grown organically had significantly higher ash content as compared to their inorganically grown and conventionally grown counterparts. Calcium, phosphorus, iron, zinc, magnesium, manganese and copper content of organically grown vegetables was significantly higher as compared to inorganically grown vegetables; a non significant difference was observed between mineral content of inorganically grown and conventionally grown vegetables in most of the cases.
