Abstract
Two greenhouse experiments on pea (Pisum sativum L.) nutrition were carried out in 1969. In the first, peas were grown in soil suspected to be deficient in Mn. and lime was added to determine whether it would prevent or aggravate any Mn deficiency symptoms. In the second experiment, peas were grown in nutrient solutions with Mn levels varying form 0 to 1.00 ppm. In both experiments, plant parts were harvested separately, dried, weighed, and analysed for mineral content. Statistical analyses were done on the results.In the first study, lime was found to increase the height, number of nodes, and dry weights of pea leaves and stems. It reduced leaf P and Mg and stem Zn, but increased Mn in the pods. In the solution culture study, 1.00 ppm Mn in solution increased the dry weight of stems, leaves, pods, total tops, and whole plants and increased the top/root and pod/stem‐and‐leaf ratios over the control. Increasing levels of Mn generally decreased pod and stem P, pod K, pod and stem Mg, root Cu, and leaf Na and significantly increased root Mg, pod Fe, pod Al, and Mn in all tissues.
