PRESENTED OF SELULOLYTIC MICROORGANISM AND THE NPK FERTILIZER TO INCREASE PRODUCTION OF ONION IN THE PEAT SOIL

Abstract

The goal of this research is to know the effectiveness of Usage of the selulolytic microorganism and the anorganic fertilizer to increase the growth and production onion (Allium ascalonicum L) that planted in the peat soil. The research is held in the Peat soil on the Experimental statioan of Agriculture Faculty of Riau University , use the Block Random Design with three replication. The treatment that is given consist of two factors, the fisrt is usage of selulolytic microorganism (0 ml/plot, 10 ml/plot, 20 ml/plot) and the second is usage of NPK fertilizer (1, ½,1/3 recommanded dosage). The Parameter that studied is dry weight of plant 55 days after planted, the rapid of relative growth, the number of clove and the weight of wet tuber per plot. Data of the research will be analyze statistically and by analysist of variance and advanced test with DNMRT 5%. The result of this research showed that interaction between selulolytic moicroorganism and the NPK fertilizer increase the dry weight of plant 55 days after planted. Usage only selulolytic microorganism increase dry weight of plant 55 days after planted and the weight of wet tuber per plot whereas usage some dosages of the NPK fertilizer increase the dry weight of plant 55 days after planted and the rapid of relative growth, the best of usage of selulolytic microorganism is 10 ml/plot and the best of dosage of urea, TSP and KCL is 1/3 recommanded dosage that is 12,5 g urea/plot, 7,5 g TSP/plot dan 5 g KCl/plot
