Abstract:
The experiment was
conducted to study the impact of sowing
interval on the yield and yield contributing
traits of sesame (Sesamum indicum L.),
under the tropical circumstance, during
2016, at the research area present near
Faculty of Agriculture, Lasbela University
of Agriculture, Water and Marine Science,
Uthal, Balochistan. Experimental treatments
were comprising three varieties of sesame,
SV1 (TS-5), SV2 (TH-6) and SV3 (4002),
and cultivated under different three sowing
dates, at 15 days interval: S1 = 1st sowing
(15 March 2016), S2 = 2nd sowing (1st April
2016) and S3 =3rd sowing (15 April 2016).
The results of various observations, i.e.
plant height at maturity (cm), 1000-seed
weight (g), seed mass (t ha-1), yield index
(%) rooting depth (cm) and root weight per
plant was found to be significant both for
the all the sowing dates and sesame
genotypes. Non significant finding was
observed in traits of biological yield per
plant (g) and root-shoot ratio. Whereas
interaction among all the treatment factors
was non-significant. Maximum yield and
yields contributing parameters was observed
in S3 = 3rd sowing (15 April 2016) and
sesame genotype SV1 (TS-5), followed by
SV2 (TH-6), while minimum yield was
noted in S3 = 3rd sowing (15 April 2016) and
SV3 (4002) sesame genotypes. On the basis
of the coastal agroclimatic condition of
district Lasbela, it was concluded that
maximum yield production was achieved
from the sesame variety (TS-5), as
compared to other two sesame (TH-6 and
4002) varieties. Sowing date of sesame at
15th April 2016 was more productive, as
compared to the other sowing interval.
Coastal climatic condition is feasible for
sesame cultivation, especially for the
sesame variety (TS-5).
