Phosphorus is given for maximum root development of the plant.
It is Good to fertilise Vegetable plant in every 3 to 4 weeks in growing season till fruit ripening.
Apart from nitrogen, potassium and phosphorus some secondary nutrient are also essential including calcium, magnesium sulphur with small amount of iron, copper, mangnese, and chloride.
