Abstract

Rhizoctonia solani is a disease that attacks gumitir nursery. But this disease can be suppressed by a pungus called Trichoderma sp. Based on their needs, gumitir flowers are used almost daily, especially por religious ceremonies in Bali. In general, gumitir flowers are widely used to make offerings so that at The time of approaching religious holidays, the need for gumitir flowers will increase. Considering how damaging sprout disease in plants, this study aims to determine the ability of Trichoderma sp mushroom mixed in seed media to control the sprout attack caused by Rhizoctonia solani in controlling Rhizoctonia solani disease in gumitir seedbed (Tagetes erecta L). Using a randomized block design (RBD) with six (6) treatments of Trichoderma sp (0, 5 grams, 7,5 grams, 10 grams, 12,5 grams, 15 grams) and four (4) replications. The result obtained from this study are the effect of Trichoderma sp dose on gumitir seedbed able to suppress Rhizoctonia solani disease with the lowest attack on T5 treatmen by 2 % at 16 HST observations compared with 71% control. The best treatment for rhizoctonia solani is on treatment of T5 at a dose of 15grams/ plastic tray but did not show any significant difference in the treatment of T3 10 grams/ plastic tray.

Abstract

This study entitled "Response of growth of stem cuttings of red roses (Rosa damascena P.Mill.) to concentrations and immersion time of young coconut water in Batu Bulan Village, Banjar Sasih, Sukawati District, Gianyar Regency". The implementation started from January 10 2021 to April 23 2021. The research aims to determine the concentration and duration of soaking young coconut water which is good for the growth of red rose plants (Rosa damascena P.Mill), flower plants are propagated generatively and vegetatively. The method used in this study was stem cuttings, namely by cutting selected parts of the plant stems. Coconut water also contains auxin and cytokinins which play a role in encouraging cells to divide and elongate rapidly so as to increase growth rate. This study used a randomized block design (RBD). .with 9 repetitions and 3 repetitions there were 48 polybags. The treatments were 0% K0L0, 25% K1L1, 50% K2L2, 75% K3L3, and 100% K4L4. The results showed that the long time immersion of young coconut water (K4L3) resulted in the number of times the first leaves appeared (K4L4) 43.75 (strands), branch length (K3L4) 45.50 (cm) number of primary leaves, (K3L4) 45.50 (strands), length of primary leaves (K4L2) 8.25 (cm) stem diameter (K3L4) 4.07.(cm) .
