Abstract

The model of interaction between the time of entries defoliation and shoot grafting models that gave the best Cacao seedling growth. The treatment design consists of two factors, namely the defoliation time of the entries and the top graft model. Times of entry defoliation times 4 times, entree defoliation at the connection (W1), entres defoliation 3 days before connection (W2), entres defoliation 6 days before connection (W3), entres defoliation 9 days before connection (W4) . The connection factor model is tested by two connection models, namely, connecting gap (S1), and diagonal connection (S2). The environmental design used is randomized block design in factorial patterns. Parameters of cocoa growth observed were the percentage of live seedlings (%), time of shoot buds (days), shoot length (cm), shoot diameter (cm), and a number of leaf buds (strands). The research is a combination of all observed parameters. The best time for defoliation is 9 days before connection. The used defoliation model shows different results that are not real.
