Effects of inter-row and intra-row spacing on growth, yield and fiber
quality of rain-fed cotton
in the Blue Nile State
Osama M. A. Elhassan and Abdelrahman H. Abdelatif
Abstract:
Field experiments were conducted during 2000-01, 2001-02, 2002-03 and
2003-04 cropping seasons, at Damazin Agricultural Research Farm, under
rainfed conditions, to study the effects of inter-row (70, 90 and 110
cm), intra-row spacing (15, 30, 45 and 60 cm) and their interactions on
growth, yield and lint quality of two cotton varieties differing in
growth habit [Barac(67)B and Albar A(57)12]. Data for each season and
the combined data were statistically analyzed. In general, wider spacing
enhanced earliness in both cotton varieties. The closer spacing produced
the shortest plants and gave the highest number of branches/m². Seed
cotton yield significantly increased due to narrowing the inter-row
spacing. The intra-row spacing had no significant effect on yield. On
average, the difference in seed cotton yield between the two varieties
was not significant. The closer spacing showed the highest number of
bolls/m², while the wider one gave the largest boll weight. The
intra-row spacing of 15 cm resulted in the lowest seed index and lint
index compared with others. The difference in seed index and lint index
due to inter-row spacing was not significant. Also, ginning out turn (G.O.T)
was not significantly affected by both inter-row and intra row-spacing.
The effects of different inter-row and intra-row spacing on yield, yield
components and fiber quality suggested the use of 70 cm inter-row
spacing for both cultivars, with intra-row spacing of 15-60 cm for Barac
(67)B and 30-60 cm for Albar A(57)12.
