Description Considering the aesthetic value of Gerbera(Gerbera
jamesonii), it is a beautiful dwarf perennial plant used as a
cut flower (ranks 4th among cut flowers demands
according to Sujatha, et al., 2002), garden flower and it
makes a good showing in exhibitions and floral
arrangements because of its numerous colours and
interesting shapes. At present, this group comprises 45
species, native to tropical Asia and Africa. Maharashtra is
one of the pioneer states for protected flower cultivation,
under which 600 ha of land is cultivated for different flower
crops under polyhouse condition, out of which more than
100 hectares area is under gerbera cultivation with 1476
lakh flowers per year with productivity of 250 flowers m-2
(Anonymous 2010). Considering the “law of minimum” of
Baron Justus Von Liebig, which states that “plants will use
essential elements only in proportion to each other, and
the element that is in shortest supply in proportion to the
rest will determine how well the plant uses the other
nutrient elements”, the effect of specific nutrients must be
tested for their importance in completing their life
cycles..Calcium concentration in plants ranges from 0.2 to
1 %. Calcium is important in maintaining the structure and
permeability of cell membranes, essential for cell
elongation and cell division and helps in uptake of N, Fe,
B, Zn, Cu and Mn. Manganese concentration in plants
typically ranges from 20 to 50 ppm. The involvement of Mn
in photosynthesis, oxidation reduction processes and in
decarboxylation and hydrolysis reactions calls the need of
Mn in plants. Therefore, the investigation was carried out
to study the effect of Ca and Mn in some physiological
properties of Gerbera.
A pot culture experiment was conducted on gerbera (cv. Goliath) at Hi-Tech Floriculture and Vegetable Project, College
of Agriculture, Pune- 5. The experiment was conducted during August, 2013 to February, 2014 to study diagnosis of
calcium and manganese deficiency on gerbera grown on cocopeat under polyhouse conditions. The experiment was
conducted lying on the basic treatment of excluding the nutrients of interest (calcium and manganese) and the
comparison with the complete nutrition in respect of growth and development of gerbera. It revealed that the deficiency
of Ca and Mn certainly cause a setback in chlorophyll content, periodical dry matter and vase life of gerbera.
