Uji Beberapa Konsentrasi Ekstrak Bawang Merah Sebagai Zat Pengatur Tumbuh Terhadap Keberhasilan Sambung Pucuk Tanaman Kakao (Theobroma Cacao.L)

This study aims to determine the effect of Trichoderma asperellum Tc-Clkt-01 and shallot extract and their interaction on the success of grafting mango seedlings. The factorial experiments in this study were arranged in a completely randomized design (CRD). The first factor is Trichoderma consisting of without and with Trichoderma. The second factor was the concentration of shallot extract above: 0, 15, and 30 ml.l−1. With three replications, 18 experimental units were obtained. The variables observed were: shoot appearance time (days) and shoot growth length (mm) one to four weeks after grafting. All data from the observations were analyzed using ANOVA at the 5% level; the average of each treatment was compared with controls (without Trichoderma and without red onion extract). Trichoderma sp. isolate Tc-Clkt-01 accelerated the emergence time of shoots by 26.87% and increased shoot length growth by 41.76-43.71% compared to the control. Onion extract at a concentration of 15 ml.L−1 accelerated the emergence of shoots by 10.45% and increased shoot length increase by 20.59% compared to the control. The combination of Trichoderma and shallot extract at a concentration of 30 ml.l−1 accelerated the emergence of shoots by 23.17% and increased shoot length by 32.94% compared to the control.
