Abstract
An investigation into the effects of mulching and
spacing on the growth and yield of ginger (Zingiber
officinale Roscoe). was undertaken at Samaru during the
1986 wet season. The treatments comprised three levels
of mulching (0, 5 and 10 cm thick), three intra-row
plant spacings (10, 20 and 30 cm) with the same inter-row
spacings of 15 cm and two varieties ('Tafin Giwa' and
Yatsun Biri') in randomised complete block design,
replicated three times.
The results revealed that mulching significantly
increased the number of offshoots, plant height, number
of leaves, leaf area and leaf, stem, rhizome and root dry
weights.
Total rhizome yield was significant and positively
correlated with yield characters. The 5 and 10 cm levels
of mulch remarkably out-yielded the unmulched treatment
by 29.5 and 21.3 per cent respectively. Generally, no
differences was observed in growth and yield at mulch
levels above 5 cm. Spacing had no v i s i b l e effect on most
of the parameters studied.
The growth and yield of the two v a r i e t i e s differed
markedly. Variety 'Tafin Giwa' was overall superior
'Yatsun Biri' and infact out-yielded it by 17.6 per cent
