Mint is one of the essential oil-producing plants. Essential oils of Mentha spicata L or spearmint are widely used as raw materials in the food, beverage and pharmaceutical preparations industries. The main components of spearmint are karvon, limonen, cineol, dihydrocarvol, myrcene, and 0.5% menthol. The components contained in spearmint have properties as herbal remedies. Plant cultivation greatly determined the results of standardized drug ingredients. Cultivation with the right planting system can affect the quality of simplicia. This research were a descriptive study to differentiate the quality of plants. This study aimed to determine differences in plant morphology, chromatogram profile and levels of spearmint essential oil between hydroponic and conventional planting systems. Observation of plant morphology includes the size, color of the stem and leaves. Essential oil content is calculated from refined oil by steam and water distillation method. Spearmint oil was analyzed on thin layer chromatography methode using the silica gel F254 as a stationary phase and hexane-ethyl acetate (8: 2) as a mobile phase, with spot visualization under UV254 and anisaldehyde-H2SO4 . The results showed that the morphology of Mentha spicata L with hydrophonic  planting systems had a bigger size in stem and leaves, but the leaves had more bright green than a conventional plant. The chromatogram profile did not show differences in the number of spots and Rf. Mentha spicata L with conventional planting systems had a sharper intensity of color on one of the volatile oil spot, and suggested  due to menthol. The levels volatile oil of Mentha spicata L hydroponic and conventional were determined as 0.0326% and 0.0323% . The Independent T-test analysis  showed that there were not a significant differences.

Abstract Mini-cutting is a technique with large applications in various crops, mainly due to the increase in the percentage and quality of adventitious roots, reducing time for the formation of clonal seedlings. The aim of this study was to evaluate IBA levels and substrates on the rooting of UENF/CALIMAN 02 hybrid papaya mini-cuttings. To perform the experiment, papaya mini-cuttings were taken from mother plants grown in pots in greenhouse, induced to produce shoots through pruning and growth regulator applications. Mini-cuttings were fixed in vermiculite or coconut fiver substrates placed in alveolate trays with 4.5x4.5x5.0 cm cells, and styrofoam trays were placed in plastic trays where different IBA levels were added in a modified Hoagland solution. After 45 days, rooted buds were transplanted to plastic pots of 600 mL of volume with soil, sand, well-cured bovine fertilizer, in the proportion of 3:1:1, remaining for 45 days. When they were taken from pots, roots were carefully washed, and the length of shoots, length of the largest root, dried mass of shoots and radicular system and root percentage were measured. The experiment was set up in a randomized complete block 5 x 2 factorial design, with 5 IBA levels: 0; 2.5; 5.0; 7.5 and 10 mg L-1, two substrates: vermiculite and coconut fiber, three replicates, with six plants per replicate. IBA levels of 5.0 mg L-1 and substrate vermiculite are the most adequate for the rooting of ‘UENF/CALIMAN 02’ papaya mini-cuttings in semi-hydroponic system in alveolate styrofoam trays with 4.5x4.5x5.0 cm cells.

Over Time

The production of lettuce in hydroponic systems with a recirculating nutrient solution has been growing, so it is necessary to evaluate the growth and quality of production under this system. Two harvest cycles were evaluated, comparing the behavior of physiological variables and growth rates on lettuce plants in a hydroponic system with a plastic cover. Lettuce plants were planted at 30 days after germination in an NFT hydroponic system. Nutrient solutions were prepared with sources of potassium nitrate, calcium nitrate, urea phosphate, magnesium sulfate and a source of minor nutrifeed. The second cycle had the highest total dry mass and leaf area index (LAI) at 43 days after transplant (dat). The relative growth rate (RGR) declined over time. The absolute growth rate (AGR) presented a sigmoid behavior as a gaussian bell shape; the leaf area index (LAI) increased until 43 dat, with the second cycle presenting the highest value; the net assimilation rate (NAR) decreased over time, with the second cycle having the highest value at 22 dat. The chlorophyll content for this variety was low, with a yellow pigmentation in the plant. The stomatal conductance (SC) in the two cycles at transplant time presented low values caused by the stress leaded by an imbalance in the pH of the solution, when the plants adapted to the system, this value increased.

The development of more efficient and productive systems for pre-basic seed potato production would improve the quality of the propagative material used by the potato growers, directly affecting the crop yields. A two-year experiment was carried out to evaluate the potato pre-basic seed production by two types of hydroponic systems (fibrocement tiles and articulated PVC gutters), two cultivars (`Baronesa` and `Eliza`) and two types of propagative material (plants coming from in vitro culture and minitubers). The PVC gutters system was highly efficient. When using minitubers, this system reached multiplication rates up to 74 tubers per plant. Minitubers were more productive than in vitro plants, independent of cultivar and hydroponic system utilized.

The Effect of Addition of Ca(NO3)2 to the Results of Lettuce (Lactuca sativa L.) in the Hydroponic System of Deep Flow Technique (DFT). Plants, in general, require composition, concentration, and volume of nutrient solutions which different depends on the type and phase of plant growth. Leaf vegetable crops such as lettuce (Lactuca sativa L.) require higher Nitrogen (N) nutrients than other vegetable crops, but the problem we faced at the moment is the hydroponic nutrients that are traded only in the general form of nutrient, therefore the addition of N nutrients in the form of calcium nitrate (Ca(NO3)2) needs to be done to meet the needs of lettuce plants. This study was aimed to determine the effect of the addition of Ca(NO3)2 and to find the optimum dosage of the addition of Ca(NO3)2 to the general hydroponic nutrition of vegetables on lettuce use DFT hydroponic system. The treatments consisted of five levels which are nutrition AB Mix general vegetable as a control, and nutrition AB Mix with the addition of 30 g, 60 g, 90 g, and 120 g Ca(NO3)2.  The results of the observation showed that the treatment of the addition of Ca(NO3)2 fertilizer had a very significant effect on all observed variables, except for the diameter of the lettuce plant. The optimum addition of Ca(NO3)2 for lettuce was found at 90.04 g with a maximum yield of 207.92 g.
