| dc.description.abstract | Anthuriums are herbaceous perennials belonging to the largest genus of the family Araceae. Anthurium andreanum Lind. called the ‘Painter’s palette’ flower is the most important species grown in the tropics. Anthurium cultivation on a commercial basis is gaining popularity in Kerala because of its high demand in the foreign market. The lack of proper management practices has increased the total period taken for the production of marketable flowers to nearly 2-2½ years. The present work was thus taken up with a view to standardize growing media and organic nutrient dosage for young anthurium plants, for enhancing their early vegetative growth and for earlier production of flowers having desirable floral attributes of size and quality. The experiment was carried out at the Department of Pomology and Floriculture, College of Agriculture, Vellayani during 2003–2005 with a view to standardize the growing media and organic nutrient dosage for young anthurium plants. The anthurium cultivar chosen for this study was Anthurium andreanum ‘Tropical’, a commercially important cultivar of Kerala. The treatments consisted of thirty six combinations of four media treatments namely sand + leaf compost (M1), sand + coir pith compost (M2), granite + leaf compost (M3) and granite + coir pith compost (M4) and nine nutrient treatments including weekly application of three cowdung treatments (2, 4 and 6 g l-1 extract) and bimonthly application of three organic manure mix (25, 50 and 75 g) treatments. Growing media, nutrient treatments and their interactions influenced vegetative growth, flower characters, vase life, fresh weight and dry matter production and nutrient content of leaves. Among the media, sand + coir pith compost was found to be the best for obtaining greater plant height, leaf area, leaf duration, petiole length at third and fourth week after emergence, shortest phyllachron, the highest fresh and dry weight of leaves and their N and K content. Plants grown in this medium also recorded earlier flowering, greater number of flowers per plant, increased spathe size, greater length and thickness of flower stalk and enhanced vase life. The inclination of spadix and its length and thickness were also found to be greater tending towards those of mature plants in this medium. Vegetative growth enhancement was also obtained with 4 g l-1 and 6 g l-1 fresh cowdung extract treatments at varying stages of growth. Greater fresh weight and dry weight of leaves were recorded in plants receiving 4 g l-1 cowdung extract at 165 and 225 DAT. These plants also recorded greater N and K content during the period while the P content was greater in plants receiving 6 g l-1 at these periods. Increased spathe size, lesser number of days to flowering, maximum length of flower stalk, maximum vase life and lesser number of days to harvestable maturity of flowers was obtained with 4 g l-1 extract. Application of organic manure mix were also found to give beneficial effects. Plants receiving 25 g organic manure mix recorded greater plant heights and leaf area during the latter stages of growth. This dosage also resulted in greater leaf duration and greater petiole length during the first and second week after leaf emergence. Fresh and dry weight of the leaves recorded were greater in plants receiving 75 g mix. The shortest phyllachron was recorded with 50 g dosage and the longest was recorded with 75 g / plant. The N and K content of the leaves were greater in plants receiving 25 g mix while the P content was greater in plants receiving 50 g mix. Spathe size, length of the flower stalk as well as the vase life of flowers was greater in plants receiving 25 g OM mix. The interaction between media treatment, cowdung and organic manure treatments were also found to influence the performance of plants. | en_US |
