Cauliflower has a high consumption level but its production is limited to its region in the highlands and the planting season. An effort to increase its production outside the highland in all seasons is using hydroponics on tolerant varieties. Selection of varieties and giving the right amounts of nutrients will optimize the production of lowland cauliflower. This study aims to determine the types of varieties and concentration of nutrient solution suitable for the cultivation of hydroponic cauliflower in the lowlands. This research uses a Completely Randomized Design (CRD) which consists of 2 factors namely varieties and nutrient solution concentration level with 9 combination treatments and each treatment consisted of 4 plants. The results showed that variety of Mona and PM 126 are better than the Diamond in the hydroponic cultivation of cauliflower in the lowlands. Concentrations of the nutrient solution did not improve growth and show no significant results, so nutrient solution from EC 2.2 to 2.4 mS/cm is better in the hydroponic cultivation of cauliflower in the lowlands.

Banana is one of the favorite tropical fruit. Banana business development begins with the provision of quality seeds. Tissue culture is a seed propagation technology that can produce large amounts of seed and a relatively short time by utilizing limited plant material. The planlets result of tissue culture needs to be acclimatization before planted in the field. Hydroponic substrate-based acclimatization is expected to produce seeds that are free from soil pathogens. Adjustment of the concentration of nutrients is important in order to produce a growth response that significantly affects and does not cause poisoning or plasmolysis. This study aims to determine whether hydroponic substrate types and nutrient concentrations affect the growth of Raja Bulu Kuning Banana plantlets. The experiment was carried out at net house, Faculty of Agriculture, Universitas Sebelas Maret Surakarta in October 2016 - January 2017. The treatment factors were substrate types (bagasse, arenga peat, steamed husk) and concentration of the nutrient solution (equivalent to EC 1.8, EC 2.0, and EC 2.5 mScm-1). The result showed that steamed husk is the best as the hydroponic substrate, while nutrient solution concentration equivalent to EC 1.8 mScm-1 is sufficient for acclimatization of Banana plantlets cv.Raja Bulu Kuning.

Pumpkin is a promising commodity to be developed as food substitute for flour-based flour. Pumpkin cultivation is currently cultivated by farmers on dry land as secondary crop. Pumpkin cultivation constraints as requires a large area and long time. Pumpkin commodities development can be done by hydroponic substrates cultivation that have advantages to accelerate the plant growth, can be cultivated on limited area, and increase the quality of plant yields. The hydroponic substrate cultivation depends on the quality of nutrients as well as the availability of the nutrients. The aim of this research is to study the response of plant flowering to the composition of nutrients (modification of the balance of Nitrogen and Phosphor) and concentration of hydroponic substrate nutrition solution and interaction between treatments. This research used Completely Randomized Design which consists of 2 factors, nutritional composition and concentration of solution with 3 replications and each treatment consist of 6 plants. Observation variables included flower age, flower position, and number of flowers. The results showed that there were interactions between the treatment of nutrient composition and adjustment concentration on the observing variables flower age appear, and flower position. Nutritional composition with the balance of elements of Phosphorus and Nitrogen shows the higher balance of Phosphorus elements followed by lower Nitrogen elements tend to give a lower response to flowering pumpkin on hydroponic substrate. Adjustment lower concentration of application solutions (20 ml concentrated in 1 L solution) or equivalent to EC 3.8-4.0 mS/cm gives a better response to flowering pumpkin on hydroponic substrate.

Banana is a tropical fruit plant that popular in people. The availability of Raja Bulu banana seedling insufficient to cover the needs. Problems in commercial banana cultivation is the least availability of clonal superior seeds. Multiplication in tissue culture technique can potentially overcome all limitations of Raja Bulu conventional seedling. So that, the objective of this research was to multiplicate an amount of Raja Bulu banana shoot using plant growth regulator in MS medium to initially produce shoot organs. The multiplication was done by Completely Randomized Design with 2 factor of IAA (0; 0,5; 1 ppm) and BAP (0, 2, 4 ppm). The data were analyzed by ANOVA and the mean compared using Duncan’s pairwise comparisons at p = 0,05. The acclimatization was design by Completely Randomized Block Design with 3 different media of palm fiber, bagasse, and banana pseudo stem then analyzed by ANCOV. The results showed there was interaction of IAA and BAP on variables at the appearance of shoots and the leaf appearance in multiplication. The medium without IAA and contained BAP 2 ppm showed the highest mean number of shoot but it was not cost effective with other treatment in this multiplication. Giving IAA 0,5 ppm with BAP 4 ppm accelerated when the shoots appear and when the leaves appear on multiplication Raja Bulu banana. There was no significant interaction or influence of IAA and BAP on plant height, leaf number, and pseudo stem diameter as acclimatization variable with 3 medium used. The percentage of acclimatization success is 76,5%.

Vanda Orchid is one of the most popular ornamental plants. Orchids have slow growth. One way to overcome this weakness is by using gamma-ray irradiation. This research aimed to study the morphological characters of various radiation doses resulting from the crossing of the Vanda Orchid. This study was carried out by observing the characters of vegetative growth for each plant on 0 Gy, 10 Gy, 20 Gy, 30 Gy, 40 Gy, and 50 Gy doses of gamma irradiation treatments. The observed variables were the increase in plant height, leaf length, root length, number of roots, number of leaves, leaf width, and leaf color. The results showed that the dose of gamma-ray irradiation were able to increase plant height. 10 Gy and 20 Gy, gamma-ray irradiation doses, resulted in discolored yellowing of orchid leaves. The discoloration of orchid leaves to light green occurs at irradiation doses of 30 Gy, 40 Gy, and 50 Gy. The morphological characteristics of Vanda sp. hybrid results gamma irradiation are high at dose 10-40 Gy. Keywords: characteristics; morphological; orchid.
