Blossom Control in Bengal Gram Quiz Quiz

Explore key factors affecting flowering and blossom management in Bengal gram cultivation. This quiz covers environmental, biological, and agricultural practices influencing flower development.

1. Optimal Temperature for Bengal Gram Flowering

   Which temperature range is considered optimal for flowering in Bengal gram plants?

   1. 10–15°C
   2. 35–40°C
   3. 20–25°C
   4. 30–35°C

   Explanation: Flowering in Bengal gram thrives between 20–25°C, supporting proper flower initiation. Lower temperatures (10–15°C) may slow growth or delay flowering, while higher ranges (30–35°C and 35–40°C) can lead to flower drop or poor pod set due to excessive heat stress.

2. Photoperiod's Influence on Flowering

   How does the photoperiod (day length) affect flowering in Bengal gram?

   1. Short days induce flowering
   2. No effect of photoperiod
   3. Long days delay flowering
   4. Short days delay flowering

   Explanation: Bengal gram is a short-day plant, meaning shorter days encourage flowering. Long days tend to delay flowering, while stating that there is 'no effect of photoperiod' is inaccurate. Short days do not delay flowering; rather, they promote it.

3. Impact of Water Stress on Blossoms

   If a Bengal gram crop suffers from water stress during flowering, what outcome is most likely?

   1. Improved pod setting
   2. Faster flowering
   3. No effect observed
   4. Increased flower drop

   Explanation: Water stress during flowering often leads to increased flower drop, reducing yield. Improved pod setting and faster flowering are incorrect, as stress hampers development. Saying there is 'no effect' ignores the plant's sensitivity to moisture availability at this stage.

4. Role of Rhizobium in Bengal Gram Blossoming

   What is the primary benefit of Rhizobium inoculation for Bengal gram at the time of flowering?

   1. Speeds up flower petal growth
   2. Prevents fungal diseases
   3. Enhanced nitrogen fixation supports flowering
   4. Boosts seed color pigments

   Explanation: Rhizobium inoculation improves nitrogen fixation, supplying essential nutrients for flowering and pod development. Preventing fungal diseases, affecting petal growth, or boosting seed pigments are not primary roles of Rhizobium in this context.

5. Effect of Excessive Nitrogen on Flowering

   What can happen if too much nitrogen fertilizer is applied before flowering in Bengal gram?

   1. Accelerated pod maturation
   2. No impact on flowering
   3. Maximum seed yield achieved
   4. Excessive vegetative growth reduces flowering

   Explanation: Overapplying nitrogen encourages leafy growth at the expense of flowering and pod development. Maximum yield and accelerated pod maturation are unlikely, and assuming no impact ignores the known effects of nitrogen imbalance on reproductive stages.
