Construction and evaluation of a hydroponic system for tomato cultivation

Hydroponic system applications can help alleviate problems caused by changes in agricultural land usage. A lot of hydroponic research has been carried out growing different plants, however, their applicability in Sindh Pakistan requires some amendment. The research was conducted at Sindh Agriculture University Tandojam to build and analyse a hydroponic structure with a continuous nutrition system for tomato cultivation. PVC pipes were used to construct the hydroponic system. Tomato plants were grown in hydroponic cups after transplanting for 15 days. The result revealed that EC and water pH ranged between 1.23 to 2.76 dS/m and 5.32 to 6.92, respectively. The water temperature varied between 18 to 24 ºC with an average value of 21 ºC. Ambient temperature and solar radiations varied between 21 to 26 ºC and 250 to 325 W/m2, respectively. The number of leaves per plant increased from 6 to 22 in 28 days after transplantation, and plant height increased from 15 to 32 cm. The total cost of construction of the hydroponic structure was 11,889/ PKR. The constructed hydroponic system proved to be a suitable technology for growing tomatoes in a protected environment with minimal space, fertilizer and water requirements.
