Abstract

The Effect of Concentration of Local Microorganisms (Mol) From Bamboo Shoots on the Vegetative Growth of Cassava (Manihot esculenta Crantz) Cassava (Manihot esculenta Crantz) is a multipurpose plant because the stems, leaves, and tubers can be used. This study aimed to determine the effect of the MOL concentration of bamboo shoots on the growth of cassava plants. The research was carried out from January to April 2022 at the Experimental Garden of the Faculty of Agriculture, Udayana University. The study used a Randomized Block Design (RBD) with one factor, which is the concentration of MOL with 4 levels of treatment, namely, control (P0), 60 ml/L of water (P1), 80 ml/L of water (P2) and 100 ml/L of water (P3). Each treatment was repeated six times, so the total treatment unit was 24 treatments. The results showed that the mole treatment of bamboo shoots on the growth of cassava significantly affected the shoot length, number of roots; has significant effect on the variable shoot emergence time and length of the root and an insignificant effect on the variables of the number of shoots, number of leaves and leaf chlorophyll. MOL of bamboo shoots with a concentration of 60 ml/L of water gave the highest yield on all variables, namely the fastest shoot emergence time (9.17 DAP), the highest shoot length (56.83 cm), the highest number of shoots (2.17 piece), the highest number of leaves (34.83 strands), the highest leaf chlorophyll (42.40 SPAD), the highest number of roots (20.33 piece) and the highest root length (59.17 cm).

Abstract

Antagonistic Test of Indole Acetic Acid Producing Bacteria Against Helminthosporium maydis In Vitro Helminthosporium maydis is the cause of important diseases in maize, including leaf blight. Leaf blight is the most dominant disease because it causes large losses. The use of biological agents is one way to treat leaf blight that is environmentally friendly. One of these biological agents is IAA-producing bacteria. This research was conducted in vitro. The results showed that there were several IAA-producing bacteria that were able to inhibit the growth of H. maydis in vitro with the highest inhibition in the treatment of B. thuringiensis GR12 isolates of 96.44% when compared to controls. IAA-producing bacteria were able to inhibit the growth of H. maydis biomass with the percentage of inhibition ranging from 73.97% - 80.82%. The treatment of IAA-producing bacterial filtrate at a concentration of 20%-90% was able to inhibit the growth of H. maydis colonies in vitro. The results of this study indicate that IAA compounds produced by bacteria are antifungal.

Abstract

The Relationship between Soil Organic Matter Levels with Diversity of Soil Macrofauna on Agricultural Land in Baturiti District This study aims to determine the level of soil macrofauna diversity on agricultural land in Baturiti District and to determine the relationship between soil organic matter levels and soil macrofauna diversity on agricultural land in Baturiti District. Sampling locations were taken on two types of land use, two organic land cultivation systems at an altitude of 903-1259 meters above sea level and conventional land at an altitude of 925-1173 meters above sea level. The method in this study is the sampling method, taking soil macrofauna and soil organic matter by direct observation to the research location at the sampling point, namely 5 types of organic agricultural plants and 5 types of conventional agricultural plants which are considered representative of the presence of soil macrofauna and represent each type of plant in the study area. Soil macrofauna sampling was carried out using 2 methods, namely pit fall trap, quadratic method and hand sorting. Sampling of organic matter was carried out by hand sorting method, on organic and conventional land in Baturiti District. Soil macrofauna found in organic and conventional land were identified and calculated values: Diversity index (H'), Abundance index (R1), Dominance (C). Soil from organic and conventional land was analyzed for organic matter content (C). The data obtained were analyzed by hypothesis testing (t) using the SPSS application to determine the relationship between soil organic matter content and soil macrofauna. The results of this study indicate that the level of soil macrofauna diversity on organic land with an altitude of 903-1259 mdpl is in the medium category (1.493- 2.421) and the level of soil macrofauna diversity on conventional land with an altitude of 962- 1318 mdpl is in the medium category (1.011- 1,961). On organic land with an altitude of 903- 1259 mdpl and conventional land with an altitude of 962 mdpl and 1173 mdpl, there is no relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it was shown that it was rejected. On conventional land with an altitude of 1318 meters above sea level, there is a relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it shows that it is accepted.
