This book describes Effects of Heavy Metals and To Increase the Productivity of Crops.Over the last few years, the production of Cereals is rapidly decreasing due to heavy metals and the utilization rate of cereals is increasing day by day by the population. With an annual world production scenario, Production of cereals is decreasing due to abiotic stresses in Agricultural field. Here Ragi is used as cereal in research work. Which is also called Finger millet and Binomial name is Eleusine coracana(L.)Geartn. Cereals show different productivity because of salinity and heavy metals effect. For this reason in this book, efforts are made to increase the productivity of cereals, using nutrients However, abiotic stresses decrease the productivity of cereals.Comprehensive are presented, effects of heavy metals and also review on the latest productivity of cereals through addition of nutrition to overcome the toxicity of heavy metals in India with an agricultural importance, all the information are based on the authors'' combined research and consulting experience.
