Abstrak

Potatoes are the most vulnerable crops toward climate change in terms of various physiological processes. The implementation of technology in seed potato cultivation was done through the installation of clear plastic shade on crops and the installation of black plastic mulch on raised beds. The plastic shade helped in (1) reducing the amount of sunlight intensity received by plants in the range of between 651 - 1435 lux, (2) maintaining the temperature between 21 – 28 oC, and (3) maintaining the humidity of the environment between 55 – 82 %. On the other hand, the plastic mulch helped in (1) controlling the growth of weeds, (2) controlling the amount of water in the soil, especially in the root zone at field capacity, and controlling soil temperature at the fixed root zone at 12 – 24 oC. Plant growth was influenced by seed quality, soil temperature and soil moisture content. The combination of the application of plastic shade and mulch plastic technology on potato seed cultivation increased the quality of plant growth that is measured from the total biomass weight of 17.2 %. The quality of plant growth directly influenced the productivity of the tuber, which it is increased by 3.3 %.
