Q.125

RPSC Agriculture Research Officer (Agronomy) - 2022

MCQ (Single Correct)

The seed rate (kg/ha) for sweet corn is -

मीठी मक्का (स्वीट कॉर्न) के लिए बीज दर (किग्रा/हेक्टेयर) है -

20 20 8 8 24 24 12 12

Optimal plant population and seed rate in maize (Zea mays L.) depend on the specific commercial type:
- Sweet Corn (Zea mays var. saccharata): Recommended seed rate is 8 to 10 kg/ha with a spacing of 60 cm x 20 cm, yielding an optimum population of ~70,000 to 75,000 plants/ha.
Baby Corn: Recommended seed rate is 25 to 30 kg/ha with close spacing of 60 cm x 15 cm (~80,000 to 100,000 plants/ha) for tender unfertilized ear production.
Grain / Field Maize: Standard seed rate is 18 to 20 kg/ha for composites and 20 to 22 kg/ha for hybrids.

Hence, the recommended seed rate for sweet corn is 8 to 10 kg/ha (Option 2).

Hence, the correct option is (B).

मक्का (Zea mays) में प्रति हेक्टेयर बीज दर उसके व्यावसायिक उपयोग और प्रकार पर निर्भर करती है:
- स्वीट कॉर्न (मीठी मक्का): अनुशंसित बीज दर 8 से 10 किग्रा/हेक्टेयर होती है (दूरी 60 x 20 सेमी, पौधों की संख्या ~70,000-75,000)।
बेबी कॉर्न: अनुशंसित बीज दर 25 से 30 किग्रा/हेक्टेयर होती है (सघन दूरी 60 x 15 सेमी, पौधों की संख्या ~80,000-1,00,000)।
सामान्य दाने वाली मक्का: संकुल किस्मों हेतु 18-20 किग्रा तथा संकर किस्मों हेतु 20-22 किग्रा/हेक्टेयर।

अतः स्वीट कॉर्न की अनुशंसित बीज दर 8 से 10 किग्रा/हेक्टेयर (विकल्प 2) है।

अतः सही विकल्प (B) है।
