The book deals with synthesis of slow release controlled micronutrient brick, which slowly diffused in the soil and available to the crop. A comparative effect of slow released micronutrient with a Liquid spray on plant Trigonella foenum-graecum L (Fenugreek) was carried out. The organic constituents such as chlorophylls, carbohydrates, lipids and proteins were estimated in Trigonella foenum-graecum L (Fenugreek) treated with liquid spray and slow released micronutrient brick. Meanwhile an elaborate enhanced amount of chlorophylls, carbohydrate, lipid and proteins were noticed in slow release micronutrient than liquid spray.
