Aplikasi Biofungisida Berbahan Aktif Trichoderma sp. dan Pupuk Kandang Sapi Terhadap Pertumbuhan Bibit Kakao (Theobroma cacao L.)
Abstract: This research aim to
knows the effect of interaction of biofungicide active ingredient Trichoderma
sp. with cow manure and best doses of biofungicide and best doses of cow manure
on cocoa seedings growth (Theobroma cacao L.). This Research was conducted in
Plant Laboratory, Disease Laboratory and experimental field faculty of
agriculture, Riau University on Bina Widya Campus Km 12,5 sub-district of
Simpang Baru, district of Tampan, Pekanbaru. This research was conducted from
August to November 2015. This research used Completely Randomized Design (CRD)
factorial that consisting of two factors. The first factor is the Trichoderma
Biofungisida (B) consists of two levels (0 and 25) g/polybag and second factor
is the cow manure (P) consists of five levels (30%, 40%, 50%, 60% and 70%)
/polybag. Both these factors resulted in 10 treatsment combinations, each
combination made three replications, so that there are 30 experimental units.
Each experimental unit consisted of two plants, so the total crop was 60
plants. Parameters measured were seedling height, number of leaves, stem
convolution, ratio of crown roots and
dry weight. Data obtained from the research results were statistically analyzed
by analysis of variance followed by a further test of Duncan's New Multiple
Range Test (DNMRT) at 5%. Based on the research the result showed that the
treatment Trichoderma biofungisida and cow manure significant on seedling
height, number of leaves, stem convolution, dry weight and had no significant on ratio of crown roots.
Treatment of Trichoderma biofungisida burnt 25 g/polybag and cow manure 50% –
60% /polybag can be recommended to get
the growth of cocoa’s seedling.
