A low cost container made from recycled material with multi objectives like tower gardening, sub irrigation and self-composting techniques to provide the optimum controlled environment for growing a wide range of agricultural products has been synthesized. For evaluation of fabricated bucket container for sub irrigation, sandy clay and silty loam have been selected. The results of the study revealed that there was saving in area of about 65.89 percent. There is a saving of 54.4 percent of water applied to the soil for plant growth. The water that applied to the field can be utilized for growing double crop in the container. ANOVA test performed at 5% level of significance for the plant heights at 20 DAT and 40 DAT indicated that the highest average plant height 46 cm was recorded in treatment T1 followed by T2, T3 and T4. From this it is concluded that the height of onion plants was good in containers compared to fields. The highest yield of spring onion was recorded in T1 compared to others. The yield of spring onion in T1 was 157g. The growth of plants and bulb size was good in sub-irrigated container than in the fields.
