Abstract

Nitrogen is a macro nutrient need by plants to enhance growth and productivity. Nitrogen element can be supplied through inorganic fertilizer, compost or biological fertilizer. The purpose of this study was to analyze the effect of vinasse compost and endophyte bacteria of Klebsiella sp. on nitrogen uptake and sugarcane growth. The treatments tested in this study were K0 = control (no compost vinasse and Klebsiella sp.), P1 = (Klebsiella sp. + 75% ZA + 25% vinasse compost), P2 (Klebsiella sp. + 50% ZA + 50% vinasse compost), P3 (Klebsiella sp. + 100% ZA fertilizer + 0% vinasse compost), P4 (without inoculation of Klebsiella sp. + 75% ZA + 25% vinasse compost), P5 (without inoculation of Klebsiella sp. + 50% ZA + 50% Vinasse compost). The treatments were arranged in a completely randomized design with five replicates. The results showed that endophyte bacteria could only enter in P1 treatment. The total N-content, N-available and N-absorption were associated with P1 treatment. Vegetative growth of sugarcane did not show significant different. The P1 treatment had the highest value of plant height and number of leaves. As for the number of tillers, on 4 terms, the highest value was observed on P2 treatment.

Abstract

Nitrogen (N) is very important element for the vegetative growth of sugarcane plants. Character N is easy to change shape and become unavailable. This research was aimed reduce the use of inorganic fertilizer, reduce the loss of N and increase N levels with utilizing gliricidia leaves and utilization endophytic diazotrophic bacteria or  fixes nitrogen bacteria. The research used a completely randomized design with six treatments, i.e.  B0i0: control (0% + 100% ZA + no added bacteria inoculation), B0i1: (0% + 100% ZA + added bacteria inoculation), B1i0 (25% + 75% ZA + no added bacteria inoculation), B1i1 (25% + 75% ZA + added bacteria inoculation), B2i0 (50% + 50% ZA + no added bacteria inoculation), B2i1 (50% + 50%  ZA + added bacteria inoculation) with 5 replication. Variable observations included test of bacterial compatibility, soil total N, NH4+, NO3-, N uptake on leves, plant height, number of leaves and number of tillers. The research results showed that bacteria applied successfully entered the leaf tissue. The treatments were not significant for soil total N, NH4+, N03-, N uptake and number of tillers but significant for plant height at 6 week after planting and number of leaves at 8 and 12 weeks after planting. The organic matter of gamal leaf and bacteria endophytic diazotrophic were able to substitute ZA (ammoniu sulphate) inorganic fertilizer on sugarcane crop at 12 weeks after planting.
