Abstract

Porang is in great demand because it is very prospective and expensive. Bulbil Porang's bulbil dormancy period depends on the season. ZPT (Growth Regulatory Substance) is very important as a trigger for breaking dormancy and stimulating roots. The aim of this study was to analyze the growth response of Porang shoots to the concentration of ZPT Auxin and the immersion time. Research design applied was Factorial RAL with 2 factors, namely Auxin concentration and Porang bulbil immersion time. Auxin concentration consisted of 4 levels, namely control (without Auxin), 100 mg/l water, 300 mg/l water, and 500 mg/l water. The immersion time factor consists of 3 levels, namely control (immersed); 1.5 hours of immersion, and 3 hours of immersion. The results showed that the 1.5 hour auxin ZPT immersion time had a significant effect on all observation parameters, namely shoot time, number of shoots, height and diameter of Porang shoots. The best growth percentage of Porang shoots resulted from the A1L1 interaction (auxin 100 mg/l water: 1.5 hour immersion). The interaction between A2L1 (300 mg/l water auxin: 1.5 hours immersion) and A3L1 (300 mg/l water: 1.5 hours immersion) treatment resulted in the best increase in height and diameter of Porang shoots.

Abstract

Eucalyptus pellita is a fast-growing in forest industrial plantation. This research aims to analyze the effect of the best Calcibor concentration on Eucalyptus pellita at Nursery Research and Development PT. Arara Abadi. This research was carried out experimentally with CRD, 1 factor consisting of 5 treatment levels, namely: not fertilized (control), 0.5 ml Calcibor fertilizer/liter of water, 1 ml Calcibor fertilizer/liter of water, 3 ml Calcibor fertilizer/liter of water, 5 ml Calcibor fertilizer/liter of water. Each treatment was repeated 1 time to obtain 20 experimental units, each experimental unit consisting of 5 seeds, for a total of 100 seeds. The results of the research showed that the application of Calcibor fertilizer to all treatments resulted in the percentage of growth of live Eucalyptus pellita seedlings reaching 100%. The results of variance analysis showed that the application of Calcibor fertilizer had a very significant on increasing the height of the seedlings, the diameter of the seedlings, and the number of leaves of the Eucalyptus pellita. The T3 treatment (3 ml of Calcibor fertilizer) was the best dose and produced better leaf quantity.
