Abstract

Mucuna bracteata is one of legume cover land that is currently much used by oil palm and rubber plantations. The benefits of Mucuna bracteata are rapid growth, high biomass yields, N fixation from the air, tolerant to the diseases and pest attacks is not well-liked by livestock because the leaves contain high levels of phenol . Activity fixation of Nitrogen from the air were marked by the formation of rhizobia. In some plantation crop Mucuna bracteata rhizobia form a slow, nodules, formed one year after planting. Based on this research required the addition of rhizobium bacteria in order to inokulan the formation of rhizobia can take place properly. The research was carried out in the area of nursery STIPAP. Research has been done from April – July 2017 with the parameter length swirl (cm), number of leaves (strands), total dry weight, root nodule rhizobia. Treatment of planting material (M) and Rhizobium no significant effect on the length of tendrils. Treatment of planting material (M) had significant effect on leaf number parameter, treatment of seed planting material(M0) 135,50; (M1) 30,75 (64% compared to M0), Rhizobium treatment had no significant effect on leaf number. The treatment of planting material had significant effect on the number of root nodule (M0) 135.50; (M1 ¬) 57 ie 42%. The effect on the weight of root nodule 15.06 g (M0), 10.08 g (M1) with a percentage of 64%. N content of Mucuna bracteata leaf in all observations belong to high category with value N> 3,1%.

Abstract

ABSTRACT White root disease (WRD) is a very harmful disease in rubber planting material preparation. The treatment method for infected budded stump has not been determined; therefore, the infected stump is usually directly eradicated through burning. This research aimed to understand the effect of the sulfuric compound to WRD rate and budded stump growth in polybag nursery. The research was arranged based on Completely Randomized Design (CRD) non-factorial with chemical concentration treatment using four levels i.e. 0 g/l (control), 2 g/l, 4 g/l, 6 g/l, dan 8 g/l that was carried out at Sungei Putih Research Center Greenhouse in Galang, Deli Serdang. The trial result indicated that the submersion of infected budded stump level two into sulfuric solution up to the concentration of 8 g/l for 15 minutes did not decrease WRD rate. The shoots growth showed was not significantly different than without submersion. The submersion method is seemed not proper to treat WRD on the budded stump since it only can be conducted once at the beginning of the stump planting into the polybag. Therefore, research on the effect of sulfur for WRD treatment on the budded stump has to be carried out variously from the dosage as well as application method viewpoint.
