Temperature control technology in broccoli plants through intercropping and crop crotalaria juncea in the lowlands of Timor island

Absence broccoli farming in the island of Timor cause dependence vegetables broccoli flowers from outside the island or imported to meet the needs of the market. The impact the selling price of broccoli flowers are very expensive. Delimiter farming on the plateau is rocky, infertile, and the difficulty of the source of irrigation for cultivation. Instead highly fertile lowlands, and has the potential of specific and fluctuating temperatures that average less than 27.2 °C for 8 months. There are varieties of broccoli capable of flowering normally at an average temperature of less than 28.15 °C Temperature same or more, many varieties that produce flowers not normal and the risk of crop failure (Arifin at al.,2017). The research aims to manipulate the temperature control via intercropping with broccoli C. juncea as a shade tree, for the suitability of the temperature that normal flowering broccoli. Experiments using split plot design. The main plot treatments three varieties, namely the Green Magic, Green Super and kompak. The subplots 5 treatments shade tree planting time, ie the time of planting a shade tree for 3 weeks before planting (WBP) broccoli, 2 WBP broccoli, 1 WBP broccoli, broccoli planting simulplanteously, and one week after planting broccoli. Total combined treatment of 15 and 3 replications. The best result is the interaction time of planting shade 1 WBP broccoli varieties of Green Super.
