<![CDATA[Pakchoi (Brassica juncea L.). is one kind of a vegetable crop that has high economic value and high nutrition. The technology of hydroponic is one of alternative cultivation using other media than soil substrates and nutrients. The purpose of this research is to determine the effect of media composition and nutrition on growth and yield of pakchoi crops and find out which treatment is best for plant growth and yield of pakchoi. Researchcarried outinthe gardenexperiment ina plastichouse, Faculty ofAgriculture, University ofTrunojoyoMadura, at an altitude of±5 mabove sea level, temperature29ºC, and± 75% RH. The research was conductedin December2011 toFebruary2012.The analysis was usednonfaktorialRAL.
