Pre-emergence herbicides are usually used to control weeds when planting until to 2 month periode and 2.5 months post-emergence herbicides to prepare a second fertilization so that sugar cane growth is not disturbed by weeds. The treatment consisted of: ametrine 80 % herbicide at doses of 0.8, 1.2, 1.6, 2.0; and 2.4 kg / ha, ametrine 1.6 kg/ha+2,4-D 865g l/ha,ametrine 1.6 kg/ha + metil metsulfuron 8 g/ha, 2 times manual weeding treatment, and control. The experimental design used was randomized block design with 4 replications. The results showed that the herbicides ametrine and ametrine + 2,4-D or metsulfuron methyl were able to suppress the total weeds growth in the cultivation of dry land sugarcane. Ametrine and ametrine + 2,4-D or metsulfuron methyl all doses are able to suppress weeds Borreria alata, Rhicardia brasiliensis, and Digitaria longifolia; except at doses of ametrine 0.8 and 1.2 kg/ha against Borreria alata at 8 and 12 weeks after application.

This research was conducted at the Greenhouse of the Horticultural Building, Faculty of Agriculture, University of Lampung in November to August 2017, aimed to determine the effect of the concentration of paclobutrazol on the growth and appearance of tuberose and to determine the best concentration of paclobutrazol in the appearance of potted tuberose. This study used a randomized block design (RCBD) with a single treatment with 6 levels of paclobutrazol concentration, namely 0, 75, 150, 225, 300, and 375 ppm with 3 replications. Homogeneity of variance was tested by Bartlett test and additivity was tested by Tukey test. Then, it was continued with the F test and with the Least Significant Difference test (LSD) at the 5% level. The results showed that administration of paclobutrazol was significantly affected pseudo stem circumference and all variables of generative growth except the length of the florets.
