Uji Beberapa Konsentrasi Bacillus sp Lokal Riau dan Beberapa Hasil Persilangan Kelapa Sawit Terhadap Jamur Ganoderma boninense di Pembibitan

Abstract

This research is aimed at finding out the main effects of some local Riau Bacillus sp and some hybrids of palm tree and the better effects resulting from the interaction between two of these on Ganoderma boninense mushroom in seedling centre. This study was conducted in Technical Services Unit (UPT) of Agriculture Faculty of Riau University. The data shows that the interaction of Bacillus sp concentration 105 , 106, and 107 cfu/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 oil palm seeds, and the intensity of Ganoderma boninense’s hit. The main factor from the treatment of Bacillus sp 105, 106, and 107 cfu/ml can triger the palm’s growth through its height accretion, the amount of sheath, the wet and dry weight, and decrease the ratio of the root crown and the intensity of stem root desease which is caused by Ganoderma boninense compared to treatment without Bacillus sp provision. The treatment factors of some hybrid of palm tree can trigger the palm’s growth as can bee seen through the augment of sheath’s numbers, the wet and dry weight of the palm’s seeds, but it tends to increase the plant’ height, and the reatio of the root crown and the intensity of stem root desease which is caused by Ganoderma boninense.
