Abstract

Weed control must use the right dose of herbicide so as not to leave a residual effect on cultivated plants and soil. This study ains to obtain the most appropriate dose of herbicide. Herbicide used in this study were methyl methulfuron and acetic acid combined. This study used a randomized block design (RCBD) witch 2 factors, factor A was asetic acid and factor B was methyl methulfuron and there were 12 treatment combinations with 3 replications. This research was conducted in the practicum of the Departement of Plantation Plant Cultivation, Lampung State Polytechnic. The total research plot was 36 experimentals units. The dosage levels levels of methyl methulfuron tested in this study were: 0%, 55%, 75%, and 105%. While the dose of acetic acid is: 0%, 50%, and 70%. Observations made in this study were weed vegetation analysis, weed cover percent, weed dry weight, Summed Dominance Ratio (SDR), and Community Coefficient Value (C). SDR values indicate that Panicum dicotomyflorum weed, Ricardia brasiliensis, Euphorbia heterophyla, and Cyperus rotundus are the dominant weeds. The results of this study indicate that there is no effect on the dose of methyl methulfuron herbicide, acetic acid, and interactions on methyl methulfuron herbicide and acetic acid on weed control in sugarcane fields (Saccharum officinarum L.).

Abstract

This study to obtain data on the number and type of FMA. Obtained amount and types of FMA in each treatment of addition of organic fertilizer dosage level. Find out whether the combination of organic fertilizer and the given organic fertilizer dose affect the amount and type of FMA. The experiment design used was Completely Randomized Design 2 Factor and 3 replications. The first factor is 4 types of organic fertilizer (P), namely: Humat acid (P) and cow manure (D), and the second factor is 4 levels of organic fertilizer dose: D0: 0%, D1: 10 tons of organic fertilizer / ha (50 g per polybag, D2: 20 ton / ha (100 g per polybag), and D3: 30 ton / ha (150 g per polybag) There were 16 experimental units and 3 total replications of 48 experimental unit plots. Myorizas were observed using binocular microscopy and digital camera, observed spores were then grouped by morphological characters including shape, color, and spore ornaments. Identification of indigenous mycorrhizae was done using manual and confirmed by using INVAM website The result of spore count on the application of organic fertilizer containing humic acid, compost fertilizer and the combination of both the highest mycorrhizae is 3,700 in the dosage of humic acid humic fertilizer 50 g + 100 g manure. 2,300 spores in organic humic acid 100 g + 100 g of fertilizer. The number of spores was moderate, ie 1,541 on humic acid fertilizer 50 g + 150 g manure, 1,323 spores at P3D3, 1,203 at treatment of P0D2, and at treatment of P2D0 mycorrhiza reached 1.096. The smallest number mycorrhizal spores of 79 spores in the dosage of manure dose 50 g. There are 4 genera of spore that found the most commonly Genus is Glomus and Acaulospora.
