The experiment was conducted during summer season of 2016- 2017 at the field of Department Farm Structures, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experimental site was fairly uniform and levelled. Hydroponic structure was designed for the cultivation of leafy vegetables by different hydroponic methods. The dimensions of portable hydroponic structure were 1375 mm high x 925 mm long and were made from locally available materials. The structure was made up of mild steel hollow pipes of size 25.4 mm which were bended and welded together to form a Quonset-type structure. Cultivation of spinach by using two different hydroponic methods was carried out under controlled atmosphere and on the open field. Solid media culture and liquid hydroponics were used and in solid media three different types of media were used on cocopeat, soil rite and 50% cocopeat and 50% soil rite. Various chemical characteristics like iron content and chlorophyll content were determined by different methods of determination of iron and chlorophyll content of spinach in Green and white portable hydroponic structure and open-field after the proper growth of crop. All the observations were analyzed by Design expert version 9.0.2.0 software was used to analyze the result using response surface methodology (RSM). Maximum Moisture content was found 90.877% and maximum leaf area was found 32.798 dm/sq. m. Yield of spinach was found greater in the green colour hydroponic structure in between 150-210 q/ha. Yield inside the white colour hydroponic structure was found between 120-200 q/ha and in the open field it was found between 50-80 q/ha.
