1. Tomato plant requires both macro and micronutrients for healthy growth. Nutrients are provided using organic and chemical sources. Nutrient requirement depends on fertility of the soil or other alternative growth medium. Hybrid varieties of tomato take more nutrients than local varieties. Farm Yard Manure (FYM), Phosphatic and Potashic fertilizers are applied in the beginning. Green manuring, farmyard manure, oilseed cake like neem cake and bio-fertilizers provide essential plant nutrients. Introduction:
