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. Not Available |
