Description Gerbera (Gerbera jamesonii; family
Asteraceae) is one of the most popular
commercial flower crop and ranks 4th among
cut flower demands (Sujatha et al., 2002). In
India, 0.190 million hectares of area is under
flower cultivation with a production of 1.031
million loose of flowers and 690.27 million of
cut flowers in the year 2010-2011.
Maharashtra is one of the pioneer states
known for its protected flower cultivation and
the area under protected gerbera cultivation ismostly confined in Pune, Satara, Kolhapur,
Nashik etc. that has nearly 600 hectares of
land out of which more than 100 hectares area
is being adopted for gerbera cultivation with
1476 lakh flowers per year with a productivity
of 250 flowers/m2 (Anonymous, 2010). The
success of gerbera cultivation under
polyhouse depends largely on nutrient
management apart from other factors. Plant
nutrition is a difficult subject to understand
completely, partially because of the variation between different plants and even between different species or individuals of a given clone. An element present at a low level may cause deficiency symptoms, while the same element at a higher level may cause toxicity. Further, deficiency of one element may present as symptoms of toxicity for another element.
Deficiency of some nutrients may delay flowering and also reduces the aesthetic value. Balancing the plants growth, need periodic monitoring to assure the nutritional requirements are being met. When growers face nutritional problems with visual symptoms, knowing key symptoms of nutrient disorders with critical tissue concentrations would assist growers in problem identification. So, in this research paper, we aimed to study the effect of Mg and Fe on nutrient concentration and uptake of gerbera.
A pot culture experiment was conducted using Goliath cultivar of Gerbera as a test
crop to study the importance of Iron (Fe) and Magnesium (Mg) in the cultivation
of Gerbera. The experiment was laid out with different treatments (factor A)
including T1 as control (complete nutrition), T2 (excluding Magnesium) and T3
(excluding Iron), thereby accounting for 16 treatment combinations with five
different days of harvesting (factor B). In both the deficiency cases (T2 and T3),
there is a significant reduction in nutrient concentration of Mg and Fe in different
plant parts such as crown + leaves (0.26% and 167 ppm), roots (0.15% and 145
ppm) and flowers (0.08% and 60 ppm) respectively. The nutrient uptake by
gerbera plant also reduced due to the nutrient deficient treatments because of the
lower production of the dry matter and also the lower nutrient concentration which
causes a great setback in the cultivation of the gerbera due to low quality flowers
with lower vase life and less aesthetic value. The experiment will generate
information on the importance of Magnesium and Iron in the nutrition of gerbera
which has got higher floricultural importance at international trade.
