Uji Beberapa Konsentrasi Bacillussp Lokal Riau dan Beberapa Hasil Persilangan Kelapa Sawit Terhadap Jamur Ganoderma boninense di Pembi- bitan

Abstract

This research is aimed at finding out the main effects of some local Riau Bacillussp and some hybrids of palm tree and the better effects resulting from theinteraction between two of these on Ganoderma boninense mushroom in seedlingcentre. This study was conducted in Technical Services Unit (UPT) of AgricultureFaculty of Riau University.The data shows that the interaction of Bacillus sp concentration 105 , 106, and 107cfu/ml and some hybryd of palm tree can improve the dry stover of palm seedlings.It also increase the amount of sheath, the wet stover, the ratio of crown roots of oilpalm seeds, and the intensity of Ganoderma boninense’s hit. The main factor fromthe treatment of Bacillus sp 105, 106, and 107 cfu/ml can triger the palm’s growththrough its height accretion, the amount of sheath, the wet and dry weight, anddecrease the ratio of the root crown and the intensity of stem root desease which iscaused by Ganoderma boninense compared to treatment without Bacillus spprovision. The treatment factors of some hybrid of palm tree can trigger the palm’sgrowth as can bee seen through the augment of sheath’s numbers, the wet and dr yweight of the palm’s seeds, but it tends to increase the plant’ height, and the reatioof the root crown and the intensity of stem root desease which is caused byGanoderma boninense.
