Northern Cameroon: Celosia trigyna is uncommon in early rainy season. Germination takes place in June when the rain becomes heavy and regular. The germination takes 1 to 2 weeks, but may be delayed by tillage at the start of cultivation (plowing, weeding). Flowering starts in August and fruiting occurs three weeks later. Fruiting continues until the plant dries out at the start of the dry season (November). A full development cycle lasts three months when germination takes place in June and only 3-4 weeks old when germination takes place at the end of the crop cycle. The flower development is linked to shortening of day length.
Madagascar: C. trigyna occurs in the middle and at the end of the cycle of rainfed crops.

Northern Cameroon: Celosia trigyna is a very common weed of annual crops in regions of Sudano-Sahelian climate Sudanese whose annual rainfall exceeds 800 mm. It is then present in 30% of the plots. It has no significant preference for the soil type and grows both in both ferruginous degraded soil and on planosol. In the Sudano-Sahelian region, it is very rare and only grows on high water retention soil. It is a weed characteristic of cultivated plots for many years and subject to semi-intensive crop management (animal traction, mineral fertilizer) or intensive (animal traction, strong mineral fertilizers and repeated use of herbicides pre- lifting of cotton). It belongs to the floristic procession of Commelina benghalensis. Although common in Sudan zone, it is rarely abundant.
Madagascar: The species grows on ferralitic soils, ferruginous soils and fertile alluvium in quite sunny areas. It is a weed of rainfed crops (corn, cotton, peanuts) in semi-arid and sub-humid areas, up to 1200 m altitude in semi-intensive culture systems without fertilization. The concerned agro-ecological zones in Madagascar are the Southwest, West, Northwest and Highlands.

Local harmfulness
Madagascar: Celosia trigyna is a weed of medium frequency and of generally low to medium abundance in rainfed cultivation: rainfed rice, cotton, corn. At the end of the cycle, it can be inconvenient for the harvesting operations due to its vegetative development.
