Estimates of rubber (Hevea brasiliensis) seed production in Nigeria
Material type:
TextSubject(s): Summary: Estimates of annual seed production of Hevea brasiliensis in Nigeria carried out in 6 estates indicated a gross national total yield of 42,980,000kg, of seed containing 13,929,818 kg of Hevea seed oil and 13,388,270kg of seed cake. Clone PB 5/;1 yielded 424.4kg/ha in Nigeria compared with only 65.5 kg/ha previously reported for the same clone in malaysia. Clonal differences in yield were considerably high. Better illuminated plots positioned on the periphery of the plantations gave significantly higher seed yield than those lying in the poorly illuminated interior. This signifies a potential for improved yield with more widely spaced planting.
