National Research Centre to study the effect of two doses (50 and 100
mg L-1) of PK foliar fertilization in the form of K2PO3
on leaf nutrient concentrations and growth parameters of cowpea (Vigna
unguiculata L.) grown under two diluted Mediterranean seawater levels
(3.0, 6.0 dS m-1) in the irrigation water in addition to tap
water (0.4 dS m-1) as control. Diluted seawater as irrigation
led to significant decreases of macro and micronutrients concentrations
in the leaves of cowpea plants. Plant height, number of green leaves,
fresh and dry weights were also negatively affected with high significance
(p0.05) as the plants irrigated with saline water. PK-foliar
fertilization in the form of K2PO3 could increase
P, K and other macro- and micronutrient concentrations in the leaves of
the salt-stressed plants. The most effective dose was the 100 mg L-1
K2PO3 with the lower salinity level (3.0 dS
m-1). Making the plants more tolerant to salinity stress, PK-foliar
fertilization could improve plant growth parameters and increase plant
heights, number of green leaves, fresh and dry weights.]]>Almoguera, C., M.A. Coca and I. Jouanin,1995107765773Ankerman, D. and L.
