The objective of this study was to evaluate growth regulators with purpose of reducing the size of heliconia ‘Red Opal’ potted plants. The experiment was carried out in randomized block design with five treatments (trinexapac-ethyl and paclobutrazol at rates of 37.5 and 75.0 mg of active ingredient per pot and control without growth regulator) and five replicates. The treatments were applied 40 days after planting the rhizomes in pots filled with soil. Thirty and 150 days after the growth regulator application, plant height, number of leaves and shoots, petioles length and leaf area were evaluated. One year after planting the rhizomes in pots the number of inflorescence and leaves (leaves, sheathing leaf bases and inflorescences) and rhizomes (rhizomes and roots) dry mass were determined. Trinexapac-ethyl had no differences compared to the control in any of the variables evaluated. Paclobutrazol proved effective in reducing plant height, leaf area and petiole length and increase in number of leaves and shoots but the effect was temporary. Also, it did not affect the inflorescences production and leaves and rhizomes dry mass. Paclobutrazol is efficient to promote height reduction and to increase the number of shoots in heliconia ‘Red Opal’ potted plants without affect the inflorescence formation but its effects is temporary.

ABSTRACT The adequate ratio in the supply of nitrogen (N) and potassium (K) for each phenological growth stage of melon is fundamental for its growth and development with the maximization of the dry mass partition between the vegetative and reproductive parts. The objective of this study was to evaluate the influence of N and K concentrations in two phenological growth stages (vegetative and reproductive stage) of melon and obtain the best N:K ratio for each one. In the first stage, four concentrations of N (8, 11, 14 and 17 mmol L-1) and two concentrations of K (4 and 5 mmol L-1) were evaluated in a randomized block design in a 4 × 2 factorial scheme with five replicates. In the second stage, in a 2 × 2 factorial scheme, the combinations of the two concentrations of N that generated the best characteristics in the previous stage and two concentrations of K (4.5 and 9.0 mmol L-1) were evaluated. The increase of the N concentration in the vegetative stage promoted the increase of the N, P and S content of leaves and the reduction of K, Ca and Mg. Moreover, it increased the number of leaves, the height of the plant (vertically tutored) and the leaf area. Therefore, 17:5 mmol L-1 was considered as the best N:K ratio for the vegetative stage. In the second stage, there was no effect of N and K concentrations on leaf area, yield and fruit quality. So, 14:4.5 mmol L-1 was considered as the best N:K ratio for the reproductive stage.

One of the efforts to increase mango production in Southeast Sulawesi is to produce high quality and high quantity mango seeds. Manure contains macro and micro nutrients that are important for plant growth and development as well as play a role in maintaining nutrient balance in the soil to improve soil properties. The aim of this study was to obtain the best manure doses applied with agrobost in improving the growth of Arumanis mango seedlings. This research was conducted in Kemaraya Sub-District of West Kendari District, Kendari City. The study design used was a randomized block design (RBD) with 6 treatments, namely: control (T0), 100 g (T1); 150 g (T2); 200 g (T3); 250 g (T4); and 300 g (T5) of manure per polybag. Each treatment was added with agrobost of 17 ml/polybag and replicated 5 times. The variables observed were plant height, stem diameter; number of leaves, and leaf area, at ages 1, 2, and 3 months after planting. The results showed that the manure added agrobost influenced the growth of Arumanis mango seedlings. The manure treatment with a dose of 150 g per polybag (T2) was the best treatment in improving the growth of Arumanis mangoes at 1, 2 and 3 months after planting. This was indicated by the plant height of 28,40; 30,94; and 32,82 cm, stem diameter of 0,44; 0,70; and 0,99 cm; and number of leaves 6,60; 7,20 and 9,00 strands were significantly higher compared to other treatments during the study

The color varieties of sweet paprika are conquering the Colombian vegetables markets, not only because of their fancy colors, but also because they are one of the best sources of ascorbic acid and carotenoids as well as phenolic compounds, important in the human diet. Therefore, basic studies related to the growth and development of the available imported varieties under greenhouse conditions on the Bogota Plateau are required.In a completely randomized block design with five replicates, biometric parameters of the hybrids Plinio, Menta RZ and Orangery were evaluated, showing that the latter one was statistically different for leaf area, leaf area index and number of leaves during the 20 study weeks, while the dry matter in the leaves, stems and roots showed no differences between the varieties. Although, 'Orangery' exhibited the highest percent of final allocation of accumulated dry matter in the fruits, being, in general, the most promising hybrid for cultivation under the research conditions.
