TAILIEUCHUNG - Modification and performance evaluation of hydroponic structure with nutrient film technique for spinach

A field experiment was conducted to study the growth and quality of spinach under controlled atmosphere of hydroponic structure at Instructional Farm Department of Farm Structure, Dr. PDKV, Akola during February, 2019 – April, 2019. The experiment was laid out in randomized block design. The structure was 1400 mm long and 970 mm wide and at a height of 1800 mm, OPI STAT statistical software was used for analyzes biometric characteristics and quality parameters respectively. The study indicated that the temperature, relative humidity, light intensity and CO2 inside the green hydroponic structure were favorable for the growth of spinach in the summer season. Green hydroponic structure showed better results followed by white and uv-polyethylene hydroponic structure. However, temperature inside the white and uv-polyethylene hydroponic structure was 1-3 0C greater and also light intensity found maximum. Biometric characteristics of spinach like plant height, number of leaves and stem diameter was found maximum in green, white and uv-polyethylene hydroponic structure than open field. The yield was found maximum inside the green hydroponic structure. Yield on the open field was found 2 times less as compare to the green, white and uv-polyethylene hydroponic structure. | Modification and performance evaluation of hydroponic structure with nutrient film technique for spinach
