Average seed yields are about 330 pounds per acre, but on-farm yields of up to 880 pounds per acre have been achieved.
The seed yield (often around 3 t/ha up to 5 t/ha) is comparable to wheat yields in the Andean areas.
Mucilage yield amounts to about 25% (by weight) of the total seed yield.
The average seed yield of P. ovata in India often exceeds 1 tonne/hectare (1000 lb/acre).
Studies on variation and association among seed yield and some component traits in Plantago ovata Forsk.
It is grown in many parts of Ethiopia, especially around the city of Harar, with an average seed yield of 2 to 2.5 t/ha.
Propagation through seed (sexual propagation) leads to a lot of genetic variability in terms of growth, biomass, seed yield and oil content.
Additionally, some definitions of carnivory require the plant to gain some tangible benefit in capturing and digesting prey, such as increased seed yield or growth.
Programs in wheat, sorghum, and sunflower are generating crop lines displaying both perenniality and agriculturally-significant seed yield.
Fertilization has also been shown to significantly increase the seed yield for up to two years after application.
