| description | Five glasshouse experiIrents were undertaken using
groundnut (Arachis hypogaea L. cv. Mat jam) plants grown in
nutrient solution under acid conditions. The minimum total
external solution concentrations of phosphorus, calcium and
magnesium required for optimum non- syimbiotic growth of
groundnut by the depleting nutrient method in 5 L pots at pH
4.75 ± 0.1 for 40 days'Were 200, 400 and 100 pM, respectively.
This corresponds to their nutrient concentrations in youngest
fully expanded leaves (YFEL) of 0.33, 1.47 and 0.32%.
The H+ ion concentration at pH 3.5 did not affect plant
top dry 'Weight but markedly decreased root growth and. length.
The pH level recommended for growth of groundnut was 4.4. The
non-toxic concentration of aluminium for growth of tops and
root elongation in groundnut supplied with 400 pM ca was < 12.2. |
