<![CDATA[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.]]>

<![CDATA[Punung is a village in Pacitan Regency which potentiall for cultivating of cocoa, on the contrary it produces low seeds quality. This condition is caused by unintensive fertilization and low light intensity caused by shading. The effort to increase cocoa seed quality was by light compensation and the use of nitrogen (N) fertilizer. The purpose of this reseach was to determine of optimum N dosage fertilizer for inproving seed quality. The research was arranged in Completely Randomized Block Design with one factor which is the varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization was applicated three times. Fertilization of P (SP36) and K (KCl), 1390 and 1000 gram tree-1 year-1 respectively. The observation variables are soil character, micro climate, leaf anatomi, physical and chemical seed quality. The result showed that N fertilizer influenced positively toward increasing potassium (K) content in leaf tissue on the first and second month, while on the third month no significant influence toward N, P and K content. However there was preference of increased N, P and K content in leaf tissue on each month although in small rise number. In the leaves tissue, there was detected that nitrogen proportion was larger than potassium and phosphorus. N fertilizer increased the physical and chemical seed quality (protein and fat content). Optimum dosage was 870 gram tree-1 year-1, highest weight of 100 seed (146 gram) and seed quality was categorized as grade 1.]]>

<![CDATA[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.]]>

<![CDATA[This study aims to determine the effect of the bamboo ash and straw compost on brown planthopper and rice production. This research was conducted in Bakaran, Sukosari Village, Jumantono, Karanganyar in 12ndDecemberMarch 2017. The study was conducted using Complete Randomized Block Design (RCBD) in paddy fields consisting of 16 plots, each was 16 m2 with Bamboo Leaftreatment, Straw Compost, and Chemical Silica with SiO2of 200 kg-1ha dosage. The variables observed were: Population of brown planthopper, stem hardness, plant height, number of tillers, number of productive tillers, weight of 100 seeds, weight of filled seed, hollow seed weight and percentage of hollow seeds. The data obtained were analyzed by Analysis of Variance (ANOVA) and if there was a significant difference, it followed by Duncans Multiple Range Test (DMRT) at 5% level. The results showed that bamboo leaf ash and straw compost not significan increase the hardness of the rice plant stems and brown planthopper population. Straw compost has the highest potential compared to other treatments because it produces the hardest stem rice and the lowest brown planthoppers population at 11 Weeks. The application of silica from various sources has no direct role in rice production.]]>

<![CDATA[Arrowroot (Marantha arundinacea) is potential plant to be developed in Indonesia. Arrowroot usually grows wild without special treatment so that makes the productivity is low. The purpose of research was to find the suitable planting age and seeds origin of arrowroot. The research was conducted from October 2016 to November 2017 at Experimental Field of Agriculture Faculty of Universitas Sebelas Maret. The research used RCBD (Randomized Completed Block Design) with two factors.The treatment of planting age consist of 3 levels (1 month, 2 months, 3 months) and seeds origin consist of 2 levels (tuber seeds and seed of nursery), each is repeated 4 times with 3 plants each replication. The results showed that the planting age treatment at 1 month of planting age has the better result compared with other treatments in almost every variables observed i.e plant height, number of tillers, tuber lenght, diameter tuber, and tuber weight per plant. The number of leaves,fresh weight plant, dry weight plant, and number of tubers are not significantly different at 1 month of planting age, although the plant is higher. The highest lenght of tuber is 20,5 cm from 2 months of planting age. Tuber weight of planting age treatment reached 31,8–124,9 gram per plant. Seed of nursery showed better results than tuber seeds although not significanly different. Between planting age and origin of seeds was no interaction.]]>
