“…Zubair et al (2006) report that the application of 200 kg ha -1 K 2 SO 4 delayed flowering for upto 20 days, while 100 kg ha -1 anticipated flowering to take place in eight days when compared with control plants (0 kg ha -1 ). Bratti et al (2012) in a study with plant gladioli, cultivate Peter pears grown in plastic containers of 5 L with limestone and potassium levels observed early flowering to 72.1 days after planting. We observed in the individual analysis of soil moisture, that there was a decrease in the number of days from plant emergence to flowering with moisture increase (Fig.…”

The management of fertilization using burnt residue from plant material associated with the management of irrigation, has demonstrated the possibility of a sustainable strategy to increase production of ornamental plants cultivated in greenhouses. The objective of this study was to evaluate the development of gladiolus plants cultivated in the Cerrado Rhodic Hapludox and subjected to doses of wood ash and volumetric soil moistures. The experiment was conducted under controlled conditions, from April to June 2014. The experimental design was arranged in randomized blocks, in a 5×5 factorial scheme, totaling 25 treatments, with four replications. Treatments were composed of five doses of wood ash (0, 8, 16, 24, and 32 g dm -3 ), and five volumetric soil moistures (7, 14, 21, 28, and 35%). Evaluated variables were: pH and soil water retention capacity; length of flower spikes and flower stems; flower numbers; and days from plant emergence to flowering. Results were analyzed using the response surface methodology with SAS software. The best results for length of flower spikes and flower stems depend on the combination of appropriate doses of wood ash and soil moisture levels. Number of flowers and days from plant emergence to flowering was separately influenced by either doses of wood ash or soil moisture, which ranged from 8 to 12 g dm -3 wood ash, and 33 to 35% soil moisture. The ash may be used as both soil corrective and fertilizer for greenhouse gladiolus production, besides improving soil water retention capacity. The ideal volumetric soil moisture for flower production is 33%.

“…However, it should be pointed out that the excess of any nutrient deranges the absorption of the others, which limits the vegetative potential. Bratti et al (2012), studying the production of gladiolus as a function of liming and K fertilization, observed that the excess of K and CaCO 3 not only compromised vegetative development and flower production, but also caused reduction in the diameter of the produced corms. These authors also observed that high K 2 O doses were responsible for the reduction in Mg absorption by plants.…”

Irrigation management, associated with the management of fertilization through the use of waste from plant material burning, has proven to be a sustainable strategy to increase the production of ornamental plants in greenhouses. The objective of this study was to evaluate the development of gladiolus subjected to soil water contents and wood ash fertilization in a Cerrado Oxisol. The experiment was conducted under controlled conditions from April to September 2014, in a randomized block design, arranged in a 5 x 5 factorial, with four replicates. The treatments consisted of five water contents (7, 14, 21, 28, and 35%) and five doses of wood ash (0, 8, 16, 24 and 32 g dm-3). Irrigation management was carried out using the portable probe Diviner 2000® . The evaluated variables were: plant height, number of leaves, shoot and root dry matter and diameter and mass of corms. The best results for diameter and mass of corms and number of leaves were obtained with combinations of soil water contents higher than 24% and fertilization with wood ash doses higher than 11 g dm-3.

“…The levels of K in the heliconia plants, with the application of the dolomitic lime differ from the results of other studies of species of cut flowers (Bratti et al, 2012). According to Malavolta (2006), the antagonism between K and Ca is a result of competition in the soil solution.…”

“…For the roots, the highest level was obtained without applying lime and N levels decreased as the dose increased. Bratti et al (2012) evaluated the level of N in gladiolus leaves after applying lime, and showed that doses over 2.05 t ha -1 promoted the absorption of N; they obtained a maximum level of 12.9 g kg -1 of N with a dose of 8 t ha -1 . According to these authors, lime facilitates the mineralization of nitrogen, making it easier for the plant to use the nutrient.…”

Production and commercialization of tropical flowers and plants has grown in recent years, mainly due to the increasing value of these products in temperate climate countries, such as heliconia, one of the most cultivated tropical ornamental plants in Brazil. This study was developed to determine the effect of lime applications on the nutrients in heliconia plants (Heliconia psittacorum L. × Heliconia sparthocircinata Arist. [cv. Golden Torch]) cultivated in yellow latosol in a greenhouse. The macronutrient levels in the leaves, pseudostem and roots of the heliconia plants were determined after cultivating the plants in containers with a medium texture, yellow latosol, collected from the 0 to 20 cm layer and submitted to doses of 0, 0.9, 2.6, 4.2 and 5.9 t of lime ha-1. Nitrogen and phosphorous performed better in the absence of the correction and in the 0.9 t ha-1 dose for the vegetative parts of the heliconia plants. The application of dolomitic lime promoted greater absorption of potassium, calcium and magnesium, and sulfur performed better for the doses 2.6 and 5.9 t of lime ha-1, for the pseudostem and roots, respectively.
