Bhindi Boosters Quiz Quiz

Explore key fertilizer management practices for thriving bhindi (okra) crops in horticulture. Enhance your understanding of nutrient requirements and mindful application for healthy yields.

1. Optimal Nitrogen Application

   Which is the best stage to apply the first dose of nitrogen fertilizer in bhindi cultivation for optimum growth?

   1. After first harvesting
   2. At the 2–3 leaf stage
   3. At sowing
   4. At full pod maturity

   Explanation: Applying the first dose of nitrogen at the 2–3 leaf stage supports early vegetative growth for healthy bhindi plants. At sowing, nutrient uptake is minimal and may result in losses. After first harvest or at full pod maturity are both too late to influence initial plant vigor and development.

2. Essential Basal Nutrients

   Bhindi responds well to which two nutrients being applied as basal (before planting) for strong root development?

   1. Phosphorus and Potassium
   2. Calcium and Boron
   3. Nitrogen and Sulphur
   4. Magnesium and Zinc

   Explanation: Phosphorus and potassium are best applied as basal fertilizers to enhance root establishment and crop strength. Nitrogen is typically split-applied. Calcium, boron, magnesium, and zinc are important micronutrients but not usually the focus of basal application in bhindi.

3. Signs of Nitrogen Deficiency

   If your bhindi plants display pale yellowing of lower leaves and stunted growth, which primary nutrient is most likely deficient?

   1. Iron
   2. Potassium
   3. Nitrogen
   4. Calcium

   Explanation: Nitrogen deficiency in bhindi typically causes yellowing of older leaves and reduced plant vigor. Potassium deficiency often shows as leaf edge browning, iron deficiencies as upper leaf yellowing, and calcium issues as distorted new growth.

4. Organic Manure Role

   Why is it recommended to incorporate well-rotted farmyard manure (FYM) into bhindi fields before sowing?

   1. It improves soil structure and nutrient content
   2. It raises soil pH drastically
   3. It reduces plant growth
   4. It attracts harmful insects

   Explanation: Well-rotted FYM adds nutrients and enhances soil texture, boosting water retention and crop health. It does not sharply change soil pH, attract pests, or impede growth; rather, it supports sustainable fertility.

5. Splitting Nitrogen Application

   How should total nitrogen fertilizer be managed during the bhindi cropping season for best results?

   1. Split into multiple doses at intervals
   2. Sprayed on leaves weekly
   3. Applied as one large dose at sowing
   4. Given only at flowering

   Explanation: Splitting nitrogen application ensures a steady supply for plant needs and reduces leaching loss. A single dose at sowing is inefficient. Applying only at flowering or spraying leaves weekly is less effective or can cause issues like burning.
