CP 858 Hybrid Maize Seeds - High Yielding Makka Variety by C.P. Seeds

CP 858 is a hybrid maize (makka) seed variety from C. P. Seeds (India) Pvt. Ltd., developed for farmers who want a dependable, higher-yielding maize crop with an early harvest window. It is a field crop seed suited to commercial as well as subsistence maize farming, and it adapts well to a wide range of soil types and growing conditions. The variety is known for its big and long ears, deep kernels, and wide adaptation, which makes it a practical choice across different maize-growing regions of India.

Each CP 858 cob typically carries 18 to 22 grain lines, with about 40 to 42 grains in each line, giving a well-filled ear with deep yellow to yellow-orange kernels. Germination is reported at around 90% to 95%, which supports uniform crop stand after sowing. The crop matures and can be harvested in about 105 to 115 days from sowing, helping farmers plan an early harvest and better field rotation. Yield potential is stated at approximately 23 to 30 quintals per acre under proper management.

CP 858 is supplied in a 4 kg packet, which covers roughly the recommended seed rate for one acre. It performs best when sown in well-drained, sandy loam soil with adequate moisture, regular watering, and balanced nutrition. This page covers the variety's key benefits, sowing and growing requirements, and practical field guidance so you can decide whether CP 858 fits your farm plan.

Key Benefits

• Higher yield potential of about 23 to 30 quintals per acre under good crop management, supporting better returns per acre.
• Early harvest in about 105 to 115 days from sowing, helping you free the field sooner for the next crop.
• High germination rate of about 90% to 95%, which supports a uniform, well-established crop stand.
• Big and long ears with 18 to 22 grain lines per cob and 40 to 42 grains per line, giving well-filled cobs.
• Deep kernels with yellow to yellow-orange colour, a desirable grain type for market and feed use.
• Wide adaptation — performs across a range of soil types and growing conditions, giving flexibility in diverse farming areas.
• Medium to tall, erect plant growth habit that supports good cob development.
• Suited to both commercial and subsistence maize farming.

How It Works

CP 858 is a hybrid maize variety, which means it is produced by crossing two genetically distinct parent lines. This hybrid vigour is the reason the variety shows stronger plant growth, better uniformity, and higher yield potential compared to many ordinary varieties. When the seed is sown in well-prepared soil with enough moisture, the high germination capacity (about 90% to 95%) helps most seeds emerge together, giving an even crop stand. An even stand is important in maize because plants that emerge at the same time compete less and use sunlight, water, and nutrients more efficiently.

The plant grows with an erect, medium to tall habit, and during the reproductive stage it develops big, long ears with a high number of grain lines and deep kernels. Deep kernels and more grain lines per cob generally mean more grain weight per ear. Because the variety has wide adaptation, it can adjust to different soil types and climatic conditions, provided moisture, nutrition, and sunlight are managed well. The crop reaches maturity in about 105 to 115 days, allowing an early harvest. Overall, the combination of hybrid vigour, uniform emergence, and good ear development is what drives the yield and grain quality farmers see in the field.

Recommended Dosage & Application

CP 858 is a seed product, so the "dosage" here refers to the seed rate and sowing method rather than a spray dose. Follow the values below for correct sowing.

Note: A 10 kg packet is sufficient for roughly one acre at the recommended seed rate. Adjust quantity based on your row spacing and local practice.

When to Use

CP 858 can be sown in two main windows — the June to September season and the October to February/March season. Choose the window that matches your region's rainfall, irrigation availability, and temperature pattern. Maize is sensitive to temperature, so aim to sow when the expected growing temperature stays between 20°C and 35°C. Very high heat during flowering and grain filling can reduce cob filling, so plan the sowing date so that the flowering stage does not fall in the hottest spell.

Sow only when the soil has enough moisture for germination, since even emergence is one of the main strengths of this variety. If you are sowing in the rainy season, make sure the field drains well and does not hold standing water, as waterlogging can damage young plants. In the October to February/March window, ensure irrigation is available for regular watering. The crop needs a minimum of 6 to 8 hours of sunlight daily, so avoid shaded fields. Since the crop matures in about 105 to 115 days, you can plan the harvest and the next crop in advance.

Step by Step Usage Instructions

1. Plough the soil 2 to 3 times to loosen it well and create a fine tilth for sowing.
2. Remove weeds and crop debris from the field before sowing.
3. Check that the soil holds enough moisture for germination; irrigate lightly if the soil is dry.
4. Confirm the soil pH is in the 5.8 to 6.8 range and that the field is well-drained and sandy loam for best results.
5. Sow CP 858 seeds at a depth of 4 to 5 cm (about 1.5 to 2 inches).
6. Maintain the recommended seed rate of 7 to 8 kg per acre.
7. Apply NPK or organic fertilizer as per your local recommendation to support crop growth.
8. Water the crop regularly and avoid overwatering; keep the field free of standing water.
9. Keep the field weed-free, especially during the early growth stage, so young plants are not crowded.
10. Monitor the crop through the season and harvest when the crop matures, around 105 to 115 days after sowing.

Precautions & Safety

• Store the seed packet in a cool, dry place, away from moisture, direct heat, and sunlight.
• Keep the seeds away from children, food, and animal feed.
• Do not use seed that shows signs of dampness, mould, or damage, as this can reduce germination.
• Sow only in well-drained soil; avoid fields where water can stand, as waterlogging harms the crop.
• Avoid overwatering — regular but controlled irrigation is recommended.
• Do not sow outside the recommended temperature range of 20°C to 35°C for best results.
• Use fertilizer as per local recommendation and avoid excess application.
