Sericulture Technology: Mulberry Cultivation Quiz

Explore fundamental concepts of mulberry cultivation, from propagation specifics to ecological needs, soil preferences, and nutrient management strategies essential for sericulture success.

1. Mulberry Plant Propagation

   Which method is most commonly used to propagate mulberry plants in sericulture?

   1. Tissue culture
   2. Through cuttings
   3. Grafting
   4. By seed sowing

   Explanation: Mulberry is mainly propagated through cuttings, allowing for true-to-type plants and easier establishment. Seed sowing is rarely used due to genetic variability, tissue culture is generally reserved for research, and grafting is uncommon for mulberry.

2. Ideal Soil for Mulberry

   Which soil condition is considered optimal for healthy mulberry plant growth?

   1. Strongly acidic, pH below 5.0
   2. Highly alkaline, pH above 8.5
   3. Heavy saline clay
   4. Slightly acidic, pH 6.2-6.8 without injurious salts

   Explanation: Slightly acidic soils between pH 6.2 and 6.8, free from injurious salts, support vigorous mulberry growth. Highly alkaline and saline soils restrict development, while strongly acidic soils can harm root systems.

3. Temperature Range for Mulberry

   For optimal mulberry growth and bud sprouting, what is the ideal mean temperature range?

   1. 38–42°C
   2. 10–15°C
   3. 24–28°C
   4. 15–20°C

   Explanation: The ideal temperature range for mulberry is 24–28°C, supporting healthy growth and bud development. Temperatures above 37.7°C or below 13°C are less suitable, and 15–20°C is acceptable but not optimal.

4. Mulberry Sapling Readiness

   How many days after planting are mulberry saplings typically ready for transplanting into the main field?

   1. 15–20 days
   2. 90–120 days
   3. 30–40 days
   4. 200–220 days

   Explanation: Saplings are considered ready for field transplanting after 90–120 days, ensuring adequate root and shoot growth. 30–40 or 15–20 days is too early for proper development, while 200–220 days would delay production unnecessarily.

5. Nutrient Management for Mulberry (Irrigated, Row System)

   What is the recommended annual fertilizer dose of Nitrogen (N) per hectare for the irrigated row system in mulberry cultivation?

   1. 375 kg
   2. 120 kg
   3. 60 kg
   4. 300 kg

   Explanation: The recommended Nitrogen dose for irrigated row systems is 300 kg/ha per year. 120 kg is correct for Phosphorus and Potassium, 60 kg is the split dose per crop, and 375 kg is specific for the V1 variety only.
