| dc.description.abstract | Philippine Agriculture has struggled to produce onion seeds for years. The Philippines is a major onion producer for domestic and foreign markets. However, domestic onion seed production has faced many challenges that have hindered its growth and self-sufficiency. Due to lack of quality seeds, infrastructure, climatic factors and import dependence, the onion seed industry and struggled to thrive. The study aims to produce an onion seed production under controlled environment agriculture and vertical hydroponics system. The effect of photoperiod in the production of onion seeds was determined in this study. The specific objectives were to establish environment for onion seed production, evaluate the effect of photoperiod in the growth and yield of onions, assess the water productivity of the system, and analyze the cost of production of onion seed under controlled environment. The study examined 12 and 16 hours of photoperiod treatments for 22 weeks. The variety of onions used was Red Pinoy. The vertical set-up for onion seed production measures 4.83 x 0.87 x 2.7 m ( L x W x H) and consists of ten (10) towers made of 6-inch-diameter by 1.5 meter long PVC pipes with 25 centimeter apart holes. Five replication of two treatments, each with six samples, were performed. Based on the requirements of onions from the bulb to the following stage, the temperature and relative humidity were also controlled throughout the study. | |
