Boost your agricultural knowledge with these essential questions on maize sowing techniques and leading varieties. Explore practical scenarios to strengthen your understanding of maize production.
Which is the best time to sow maize in a typical Indian Kharif season for optimal growth?
Explanation: Mid-June to July aligns with the onset of monsoon, providing ample moisture for maize germination. October to November and December to January are Rabi season timings, which do not suit maize in most regions. February to March is generally for spring crops or off-season planting.
What is the recommended seed rate for normal sowing of hybrid maize per hectare?
Explanation: The ideal seed rate for hybrid maize is 18–20 kg/ha to ensure proper plant population. 5–7 kg is too low for sufficient density; 45–50 kg and 30–32 kg are excessive and may cause overcrowding and resource competition.
Which of the following is a widely grown hybrid maize variety in India known for high yield?
Explanation: HQPM 1 is a high-yielding hybrid maize popular in India. IR 64 is a rice variety, while PBW 343 is a wheat variety and K 9108 is a rice variety; thus, they are incorrect for maize.
For optimal maize development, what row-to-row spacing is generally recommended?
Explanation: A row spacing of 60–75 cm provides enough space for maize plants to grow vigorously. Narrower spacings like 15–20 cm and 30–35 cm lead to crowding, while 90–100 cm is wasteful of field area.
Why is seed treatment done before sowing maize seeds?
Explanation: Seed treatment helps prevent fungal and bacterial infections, ensuring healthier crop establishment. It does not affect grain color, irrigation needs, or directly enhance plant height.
