D.R. Singh et al. Morinda citrifolia L. – An evergreen plant for diversification in commercial horticulture
of 4.62, 4.50 and 4.39 ppm in 75%, 50% and 100% sea water irrigation
treatments, respectively.

Comparison of nutrients in leaves (Morinda citrifolia L.) irrigated with
normal water and sea water revealed that the calcium content was invariably
higher (5462 ppm) in leaves of normal water than in leaves of sea water
(539.17ppm). Magnesium content was higher (570.60 ppm) in leaves of
normal water than about 50.23 ppm in sea water leaves. Invariably higher
content (185.09 ppm) of Iron was recorded in sea water leaves and the
lowest content (4.47 ppm) in leaves of normal water. Low content of copper
was found and it was higher (4.62 ppm) in sea water leaves and only about
2.23 ppm in normal water leaves. (Table 5).
Soil analysis
Nutrient analysis in soils collected near mother tree of Morinda citrifolia
L. (Table 6) showed that potassium content was invariably higher (151.10
ppm) in Sippighat soil followed by Wandoor soil (112.30 ppm) and lowest
in farmers field located at Memio. Similar trend was observed in sodium
content which was invariably higher in Sippighat soil (113.10 ppm) and the
lowest in Phoenix Bay and Co-operative Bank (26.0 ppm).
The soils of Sippighat are also rich in Calcium (8409.36 ppm) and the lowest
(818.11 ppm) in farmer’s field. Magnesium content was higher (953.10
ppm) in soil series of Wandoor and lowest in farmers field (818.11 ppm).
Among the other micronutrients, iron content was invariably higher (89.06
ppm) in Wandoor series of soil and lower (10.81 ppm) in Phoenix Bay
series of soil. Manganese seems to be higher followed by iron content, and
it was higher (82.88 ppm) in Sippighat series of soil and lower in Memio
series (3.12 ppm). Higher content (2.21 ppm) of Copper was found in
Garacharma series of soil and least (0.08 ppm) in Phoenix Bay series of soil.
