Plant Nutrition starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Nutrition.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12

A plant is grown in a nutrient solution lacking iron. What symptoms would you expect to observe?
A hydroponic experiment is set up with two groups of tomato plants. Group 1 receives a complete nutrient solution, while Group 2 receives a solution lacking boron. After three weeks, Group 2 shows poor fruit set and abnormal root growth. Explain the physiological basis for these observations.
