Cobalt in Soil
Naturally less than 50ppm concentration
Must be Supplemented
Vitamin B12 in Plants
Bacteria live in a mutual relationship with plants
Reacts with bacteria in pea plant roots and stimulates growth.
Known as NPK
NPK levels can determine plant overall health
Miller and Tarrant (1983)
Alternate Hypothesis-H(a)- Both Cobalt and the Vitamin B12 fertilization have significant effects on the growth of the pea plants with the presence of Rhizobium Leguminosarum, and supports the work of Gad and Kandil
Null Hypothesis-H(o)- Neither the cobalt or the Vitamin B12 have an effect on the growth of the peas with or without the presence of Rhizobium Leguminosarum
Effects of Cobalt and Vitamin B12 fertilization on the growth of Pisumsativum L.
