KSM 8409

Field Performance of KSM 8409

When working with the KSM 8409 hybrid, the first thing you notice is its predictability. Years of experience with this French selection from Tso Saratov have shown that this simple hybrid consistently delivers its performance metrics, even under moderate agronomic conditions. The 120–140 day maturity range allows for precise planning of the harvest campaign, ensuring we stay within optimal weather windows.

Field Hardiness and Crop Protection

For an agronomist, avoiding unexpected disease pressure is key. In fields where we planted KSM 8409, resistance to loose smut was consistently high. An important note: despite the stated resistance, we always remain cautious regarding onion stem smut, making fungicide application during the vegetative stage a standard operating procedure rather than just a suggestion. The hybrid responds well to intensive care and is not prone to lodging, which significantly simplifies combine operations during the autumn.

Economic Viability

The intermediate grain type, with its characteristic yellow-orange color, is excellent both as a commodity grain and for processing (specifically for alcohol production). Alcohol yield is consistently high, making this hybrid highly liquid in the market. Regarding seeding density, we stick to the 65–80 thousand plants/ha range; this is sufficient to unlock the cob’s potential without causing excessive competition for soil moisture.

• Type: Simple hybrid, stable across various growing cycles.
• Grain: Intermediate type, high yield for ethanol processing.
• Density: 65–80 thousand plants/ha — optimal for most regions.
• Maturity: 120–140 days, ideal for effective field drying.

Managing KSM 8409 is straightforward: it requires no specialized high-maintenance inputs, delivers stable grain test weights, and responds excellently to mineral fertilization.
