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

The productivity of oil palm plants is influenced by genetic factor planting materials, soil, climate, cultivation and plant maintenance. Nursery is the first step to prepare the prime plant material. In the implementation of the nursery, fertilization is one important maintenance factor and should be done with reference to 4T (Exactly Types, Dosage, Time and Method). Loss of fertilizer is an important thing to be controlled. This research is a conservation action by packing fertilizer in sachet bag and conservation treatment. The research was conducted in August 2016- June 2017 at STIPAP. The study used 2x2 Factorial Design with the first Factor of Broadcast System, Sachet and the second factor was with and without conservation. The best treatment was SK1 Sachet application and conservation increased leaf number 14,44 (6%), girth 18,60 cm (14%) and chlorophyll 63,16 (20%).
