Bengal Gram Booster Quiz Quiz

Enhance your understanding of fertilization practices for Bengal gram (chickpea) cultivation with these easy, focused questions. Perfect for farmers and students interested in improving pulse crop yields sustainably.

1. Essential Nutrient for Bengal Gram

   Which primary nutrient is most important for initial healthy growth in Bengal gram cultivation?

   1. Magnesium
   2. Nitrogen
   3. Zinc
   4. Manganese

   Explanation: Nitrogen is a crucial nutrient at the early crop stage, supporting growth and development. Zinc, magnesium, and manganese are essential micronutrients but are needed in smaller quantities and serve more specialized functions.

2. Role of Rhizobium Inoculation

   Why is Rhizobium inoculation recommended before sowing Bengal gram seeds?

   1. It increases phosphorus uptake directly.
   2. It prevents leaf fungal diseases.
   3. It acts as a pesticide against soil insects.
   4. It enhances root nodulation for improved nitrogen fixation.

   Explanation: Rhizobium inoculation encourages root nodulation, making atmospheric nitrogen available to the plant. It does not directly act as a pesticide, enhance phosphorus uptake by itself, or prevent fungal diseases.

3. Optimal Fertilizer Application Timing

   When should the major portion of fertilizers be applied for Bengal gram crops?

   1. After harvest
   2. At the time of sowing
   3. At flowering stage
   4. Half at sowing, half at pod filling

   Explanation: Bengal gram benefits most when fertilizers are applied at sowing, ensuring nutrients are immediately available. Later applications such as at flowering, pod filling, or after harvest are less effective for early growth.

4. Micronutrient Deficiency Symptoms

   A Bengal gram field shows yellowing of younger leaves and poor pod setting. This is most likely due to a deficiency of which micronutrient?

   1. Calcium
   2. Boron
   3. Iron
   4. Zinc

   Explanation: Zinc deficiency in pulses often causes yellowing of young leaves and affects pod development. Iron typically affects older leaves, calcium is needed for cell walls, and boron deficiency leads to malformed pods but less yellowing.

5. Balanced Fertilizer Use

   What is the main benefit of using balanced fertilizers (containing both macro and micronutrients) in Bengal gram fields?

   1. Improved plant health and higher yields
   2. Elimination of all pest attacks
   3. More effective weed control
   4. Faster seed germination only

   Explanation: Balanced fertilizers supply all essential nutrients, supporting plant health and yield. They do not directly control weeds, only speed germination, or guarantee complete pest elimination.
