“…In May 2012, greater 2012 N rates led to more vigorous growth of 'Immortality' TB iris. These results are consistent with those reported for gladiolus (Gladiolus L.) (Khan et al, 2012) and dahlia (Dahlia Cav.) (Younis et al, 2009) of which the height of plants was improved by higher N fertilizer rates.…”

Tall bearded (TB) iris (Iris germanica L.) has great potential as a specialty cut flower due to its fragrance and showy, multicolor display; however, limited research has been reported on optimal nitrogen (N) nutrient management for TB iris. The objectives of this study were to investigate the effects of N fertilizer rate on plant growth and flowering of ‘Immortality’ iris and determine the influence of both stored N and spring-applied N fertilizer on spring growth and flowering. On 14 Mar. 2012, rhizomes of ‘Immortality’ iris were potted in a commercial substrate with no starter fertilizer. Plants were fertigated with 0, 5, 10, 15, or 20 mm N from NH4NO3 twice per week from 28 Mar. to 28 Sept. 2012. In 2013, half of the plants from each of the 2012 N rate were supplied with either 0 or 10 mm N from 15NH415NO3 twice per week from 25 Mar. to 7 May 2013. Growth and flowering data including plant height, leaf SPAD, number of fans and inflorescence stems, and length of inflorescence stem were collected during the growing season. Plants were harvested in Dec. 2012 and May 2013 to measure dry weight and N concentration in leaves, roots, and rhizomes. Results showed higher 2012 N rates increased plant height, leaf SPAD reading, and number of inflorescence stems at first and second blooming in 2012. Greater 2012 N rates also increased plant dry weight and N content in all structures, and N concentration in roots and rhizomes. Rhizomes (58.8% to 66.3% of total N) were the dominant sink for N in Dec. 2012. Higher 2012 N rates increased plant height, number of fans, and the number of inflorescence stems at spring bloom in 2013. In May 2013, N in leaf tissue constituted the majority (51% to 64.3%) of the total plant N. Higher 2012 N rates increased total dry weight, N concentration, and N content in all 2013 15N rates; however, leaf dry weight in all plants was improved by 2013 15N rate. Percentage of tissue N derived from 2013 15N (NDFF) decreased with increasing 2012 N rate. New spring leaves were the dominant sink (56.8% to 72.2%) for 2013 applied 15N. In summary, ‘Immortality’ iris is capable of a second blooming in a growing season, this second blooming dependent on N fertilization rate in current year. A relatively high N rate is recommended to produce a second bloom.

“…The results indicated that using autoclaved vermicompost as organic material and autoclaved vermicompost enriched with bacteria formulation increased the yield, quality of corms and flowers of Gladiolus grandiflorus L.. Our results are compatible with the findings of other researchers (Gangaharan and Gopinath, 2000;Atta-Alla et al, 2003;Khan et al, 2012;Singh et al, 2016;Tirkey et al, 2017;Akter et al, 2017). Growth and development of plants is due to the presence of humic acids (Albanell et al, 1988;Joshi et al, 2015) and micro and macronutrients in plantavailable forms (Orozco et al, 1996;Joshi et al 2015) in vermicompost.…”

The use of environmental and sustainable ornamental flower production practices with renewable resources has drawn worldwide interest. One of these renewable resources is vermicompost (earthworm castings). In recent years, increasing demand for improving environmental quality have focused on the importance of Plant Growth Promotion Bacteria (PGPBs) in agriculture. Vermicomposts also help microbial agents function effectively in soil. In this study, a total of six treatments [A: PGPB formulation, B: Not autoclaved vermicompost, C: Autoclaved vermicompost, D: Not autoclaved vermicompost+PGPBs, E: Autoclaved vermicompost+PGPBs, F: Control (untreated bacteria and vermicompost)] were tested for their effects on the plant growth and development parameters in gladiolus (Gladiolus grandiflorus L. ‘Red Beauty’) in greenhouse condition. Vermicompost was added to the related pots by dissolving in water. After the addition of vermicompost, PGPB formulation was given immediately to related pots. All the treatments were applied to soil once in three leaf stage, close to the plant root zone. Parameters in terms of yield and quality attributes of plant and corm were determined and analyzed. The treatment A increased in plant height of gladiolus of 24.55% rate. The earliest times to flowering was determined in E application (100.48 day), which also increased in corm diameter with rate of 17.41% and number of corms and cormels with rate of 151.83% according to F application. Results indicated that the treatment E promoted overall better performance as compared to other treatments diameter of flowers for number of leaves per plant, number of florets per spike, stem diameter, spike length, fresh and dry weight of flowers, the number and diameter of corm. Autoclaved vermicompost can be good choice in gladiolus cultivation but it should be enriched with PGPB.

An experiment was conducted at the research field of Horticulture Research Centre, BARI, Gazipur during Rabi season of 2012-13 to 2014-15 to evaluate the yield and yield attributes of Marigold (var. BARI Marigold-1) to different doses of N, P and K fertilizers and to find out the optimum and economic doses of NPK for maximizing flower yield. Eleven treatments as T 1 , T 2 , T 3, ……, T 10 and T 11 comprising with four levels of fertilizer nutrients each of N (0, 60, 90 and 120 kg ha ) for the year 2012-13, but significantly different from all other treatments for the years 2013-14 and 2014-15, respectively. Flower yields were increased in T 3 treatment (N 90 P 40 K 90 kg ha -1 ) by 81.34, 62.53 and 49.53%; 146.00, 119.39 and 108.84% and 121.20, 92.13 and 84.11% over their control in respect to the years 2012-13, 2013-14 and 2014-15. The highest benefit-cost ratio 7.14 was obtained from T 3 (N 90 P 40 K 90 kg ha -1 ) followed by T 4 (6.53) treatment. From the quadratic regression equation averaging three years data the optimum and economic doses 103.75 and 102.44 kg N; 36.67 and 36.31 kg P and 90.10 and 88.43 kg K, respectively were found which could be recommended for marigold production in Grey Terrace Soil of Joydebpur under AEZ 28.
