Abstract
Investigation was carried out at Samaru during the 1966
wet season to observe the effects of three plant populations
(100,000; 250,000 and 400,000 plants/ha), three Bowing datea
(2k June, 15 July and 5 August, 1986) and two varieties
(Pb-till1 and E8) on seed yield and yield components of sesame.
Increasing plant population from 100,000 to 250,000/ha
increased seed yield by 27%. Further increase in plant
population from 250,000 to M30,000/ha resulted in no
significant increase in seed yield.
Although the effect of plant population on number of pods,
seed yield/plant and number of seeds/plant was not significant,
these characters decreaBed with increasing plant population.
Number of seeds/pod, length of pods and 1,000 seed weight were
also not significantly affected by plant population.
The earliest sown sesame with a mean seed yield of 319.00
kg/ha, outyielded the second and third sowinga by averages of
37.80% and 55.20%, respectively. Seed yield reduction with
delay in sowing were caused mainly by decreases in the number
of pods/plant, seed yield/plant, number of seeds/plant and
number of seeds/pos.
The variety E8 excelled Pb-till in yield and yield
components. All possible treatment lnteractions had
significant effect8 on one parameter or the other. However,
none of the treatment interactions influenced seed yield.
There were positive and significant correlations
between seed yield and yield components measured.
