Abstract

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.

Abstract

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.
