Abstract/Description: | A pot experiment was conducted using Gerbera as a test crop to evaluate the importance of iron (Fe) and magnesium (Mg) in production of Gerbera. The experiment was laid out with 15 treatment combinations including T1(H1 to H5) as control (complete nutrition), T2(H1 to H5)excluding magnesium and T3(H1 to H5) excluding iron, where H1 to H5 represents the days of harvesting at 115, 130, 145, 160 and 175 days after transplanting (DAT) respectively. Development of chlorotic spots started in T2H3 and T3H1, progressing gradually into interveinal chlorosis towards the end of the experiment as compared to control. Root length and the development of color in petals were found to be less in the treatment combinations where certain nutrients were excluded. |
Description: | Gerbera (Gerbera jamesonii; family Asteraceae) is one of the most popular commercial flower crop and ranks 4th among cut flower demands [1]. 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 that has 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 [2]. The area under protected gerbera cultivation is mostly confined in Pune, Satara, Kolhapur, Nashik etc. This crop is having lot of scope for export. The success of gerbera cultivation under polyhouse depends largely on nutrient management apart from other factors. The demand for Gerbera as a commercial flower crop is increasing gradually because of its large size, long stalk length, attractive colour, shape and its long vase life. Therefore, it is more popular throughout the world and marketed in the international florist trade in huge quantities. In plant nutrition, the deficiency of an essential nutrient may cause a huge setback in cultivation of gerbera as the deficiency shows its symptoms in flowers and leaf portions. To reinvestigate the essentiality of iron and magnesium in flower crops supporting the theory of “law of minimum”, this research was carried out using gerbera as test crop. |
