Pengaruh Pemberian Pupuk Organik Cair Air Kelapa dan Plant Growth Promoting Rhizobacteria Akar Bambu Terhadap Petumbuhan Bibit Kakao (Theobroma cacao L.)

Abstract

Nursery is an important factor in cocoa plant cultivation. This current research aims at finding out the effect of providing LOF from coconut water and PGPR from bamboo roots on the growth of cocoa seeds along with its interaction. The research was conducted in Makarti Jaya Village, Taluditi Subdistrict, Pohuwato Regency, Gorontalo Province, from February to April 2021. The research employs a factorial randomized block design which comprises two factors. The first factor is LOF from coconut water with three levels of treatment, namely 30 ml/1 lt, 40 ml/1 lt, and 50 ml/1 lt, whereas the second factor is PGPR from bamboo roots with three levels, namely 30 ml/1 lt, 40 ml/1 lt, and 50 ml/1 lt. In this case, each treatment is replicated three times. The parameters observed include plant height, leaf number, root length, and root number. The data analysis uses Analysis of Variance (ANOVA) with an LSD test of 5%. The research finding reveals that the provision of LOF from coconut water and PGPR from bamboo roots has a significant effect on the growth of cocoa (Theobroma Cacao L.) seeds which encompasses plant height, leaf number, root length, and root number. In addition, the dose of 50 ml/lt of coconut water is the best dose among the three doses used.
