Tomato (Lycopersicum esculentum Mill) is one of horticulture commodities with high economic value and still need seriously handling especially for increasing fruits quality and quantity. However the production of tomato has not fullfilleed the demand yet. Therefore it is necessary to develop production. On lowland, the issue not only high temperature but also availability of water is unpredictable.This study aimed to investigate the effect of irrigation frequency on the growth of Mutiara, Opal, and Gondol tomato variety. This research was conducted at the Greenhouse Laboratory of the Agriculture Faculty, Sebelas Maret University with attitude 95 m asl. Implementation of the research conducted from January to May 2013. This research used completely randomized factorial design with two factors, namely variety of tomato (Gondol, Opal and Mutiara) and watering frequencies (everyday, once in 3 days, once in 6 days, and once in 9 days). The results showed that plant height, number of leaves and number of branches are influenced by the variety of tomato and irrigation frequency, whereas chorophyl content is influenced by the watering frequency. Growth component and chlorophyll content of tomato decreased with increasing irrigation frequency.

Tomato is one of the agriculture commodity that has many benefits. However, the production of tomato in in low land is still low so it needs effort to increase production. Issues that facing in low land cultivation are high temperature and uncertain water availibility. This study aimed to investigate the effect of watering volume on growth of tomato. This research was conducted at the Greenhouse and Laboratory of Plant Fisiology and Biotechnology, Faculty of Agriculture, Sebelas Maret University. Research was conducted from December 2012 to May 2013. This research used completely randomized factorial design with two factors of treatment, namely variety of tomato were Opal, Gondol and Mutiara and watering volume (4,4 l, 3,42 l, 2,34 l, and 1,28 l in each watering). Data were analyzed by analysis variance and continued by Duncan Multiple Range Test level of 5%. The results showed that the higher of watering volume increases the growth of tomato. Plant height, number of branch, leaf area, dry weight of shoot, dry weight of root and the length of root increase with increasing watering volume. The appropriate tomato that can be developed in the various watering is Gondol.

Cauliflower is one of the popular vegetables and has high economic potential. The need for vegetables is high but the productivity is increasingly starting to decline due to narrow land. Hydroponic technology does not require fertile are. Hydroponics of cauliflower expected to increase economic value. Bagasse has characteristics wet and easy to absorb water is very suitable as a media hydroponic substrate. The experimental research was held out from August 2016 until February 2017 in the screen house of the Faculty of Agriculture, Sebelas Maret University, Surakarta The experiments using complete randomized design with 2 treatment factors consisted of various nutrients (2 types) and media (3 types) resulting in 6 treatment combinations, each repeated 3 times. Nutrient types are standard nutrients and modified nutrients (standard K reduction nutrients).The types of media types are bagasse, bagasse + gravel, and bagasse + red brick fractions. Bagasse + fragment red brick showed better yield on volume of root, large of leaf, biomass of plant and age of flower. While the highest of plant on media bagasse + gravel.
