“…Differences in pH may also contribute to variation in nutrients and phytochemicals in plants. Soil pH is known to vary in time and space, and has a major influence on solubility and availability as well as potential phytotoxicity of metals (Atwell, 1999, Etukudo andOsim., 2018). The availability of nutrient elements is strongly affected by soil pH, such that magnesium and zinc contents of plants decreases greatly with increasing pH (Anoliofo, 2006, Pajevic et al, 2004.…”

“…Physiological processes in plants such as respiration, assimilation, photosynthesis and metabolism are influenced by various climatic factors such as temperature, humidity, precipitation, light intensity and altitude (Agbede, 2009, Etukudo et al, 2015. It is important to note that the effects of these factors vary considerably from one nutrient element to another (Ames, 1997, Etukudo andOsim., 2018). According to Martinez-Ballesta et al, 2010, the contents of mineral elements present in plants are influenced by factors such as genetic properties of the crop species, climatic conditions, soil characteristics and the degree of maturity of the plant during harvest.…”

The effect of different soil conditions on some physiological indices of Costus afer was studied in two locations (Otuoke and Opolo) in Bayelsa State, Nigeria. The soils physico-chemical properties as well as mineral elements and phytochemical contents in leaf samples were assessed using standard procedure. The descending order of mineral elements in location I were, P > Ca > Mg > K > C > H > AI >Na > N, while that of location 2 were, P > Ca > C > K >Al >H > Mg > Na > N. The contents of calcium, magnesium, sodium, potassium, nitrogen and phosphorus in leaves of C. afer in location I were significantly (P < 0.05) higher than those of location 2, while the iron, zinc and lead contents in leaves of the test plant in location 1 were relatively higher than that of location 2. There were also marked variations in phyto chemical contents in leaves of the test plant between the two locations. This study indicates that soil factors have a considerable influence on the mineral elements and phytochemical contents of Costus afer.
