PENGARUH PERENDAMAN URIN SAPI SEBAGAI ZAT PENGATUR TUMBUH (ZPT) ALAMI TERHADAP KEBERHASILAN STEK BUAH NAGA SUPER RED (Hylocereus costaricensis)
The purpose of this study was to determine the effect of growth regulators naturally cow urine on the results of shoot growth in super red dragon fruit cuttings are best with different soaking treatment. This research was conducted in the campus environment Samarinda State Polytechnic Agriculture, held in Los Shadows Laboratory of Agronomy, Crops Cultivation Program. The timing of the study for three months, starting from November 2014 until January 2015. This research is organized into three levels of treatment and implemented using data processing methods completely randomized design (CRD). At each stage of treatment consists of 10 seedlings. Standard of treatment in this study consisted of P0: without treatment (control), P1: Cuttings dragon fruit super red soaked with urine concentrations cattle 500 ml / 500 ml of water, and P2: Cuttings dragon fruit super red soaked with urine concentration of pure cow of 1,000 ml. Variables observed that the number of shoots, shoot length (cm), and the circumference of the trunk shoots (cm). At the level of treatment P2 (pure cow urine concentration 1.000 ml) were able to give the best results on a variable number of shoots is 0.8 and the variable amount to 14.3 cm long shoots, and the shoots are variable trunk circumference of 7.1 cm.
