Abstract

Alitta Forest, located in the city of Parepare, South Sulawesi, has an area of 84 ha, a portion of this forest area is functioned as part of a botanical garden. The jompie botanical garden has an area of 13.5 ha, with a collection of plants reaching 90 species originating from 81 plant clans and as many as 77 species that have been identified. In addition to a collection of high-level plants, jompie botanical gardens also have a diversity of microorganisms that have not been identified, especially microorganisms that symbiosis with plant roots known as mycorrhiza, so the purpose of this study is to identify and identify the abundance of mycorrhizal spores in the jompie botanical garden found in rhizosphere Gluta renghas L.. The research began with taking the rhizosphere under the stands of wet trees in the jompie botanical garden, which was then continued to identify and calculate the abundance of spores in the microbiology laboratory of Makassar's research and development environment and forestry. The identification results of mikoiza spores native to the jompie botanical garden show that they are found in two genera, namely; Acalauspora sp consisting of two morphotypes, and the genus Glomus sp consisting of one morphotype, with an average spore abundance of 45.3 per 100 grams rhizosphere

Abstract

Rice is the main commodity in Indonesia so it needs to be supported by technological innovation in the context of increasing production. Currently, the Agricultural Research and Development Agency has created technological innovations to increase rice production because it is necessary to disseminate information on technological innovations so that all users can know and take advantage of these innovations. The purpose of writing this paper is to provide information and an overview of some of the current agricultural technological innovations in Indonesia that contribute to increasing rice production in Indonesia. Several agricultural technology innovations are currently being implemented such as new superior varieties technology, planting jajar legowo, Salibu rice cultivation system, hazton rice cultivation, SRI rice cultivation technology, integrated planting calendar, and integrated crop management. These technological innovations have had an impact on increasing rice production in Indonesia

Abstract

This study aimed to observe (1) The formation of parthenocarpy fruit in cucumber with the application of Giberelin hormone and (2) the concentration of Giberelin to form the parthenocarpy fruit on cucumber. This study was held at campus 2 trial land, Faculty of Agriculture Cokroaminoto University, Palopo. The method used in this study was group randomized design method with five treatments and three replications, i.e P0 (without Giberelin application), P1 (200 mg/L Giberelin), P2 (250 mg/L Giberelin), P3 (300 mg/L Giberelin) and P4 (350 mg/L Giberelin). The result showed that the application of Giberelin with 350 mg/L concentration (P4) significantly affected the formation of parthenocarpy fruit on the number of seed produced with 379.96 seeds. The highest number of seeds produced was observed in control treatment (P0) with 496.27 seeds. Furthermore, the fruit fresh weight, diameter, and length had no significant difference

Abstract

The obstacle of chilli pepper development in saline is that there is no salinity tolerant variety, so it is necessary to assemble tolerant varieties. Information on tolerant genotypes, selection criteria and determination of new selection methods at the germination level are needed to make it easier for breeders to select prospective tolerant varieties early. This study aims to determine tolerant genotypes, appropriate selection criteria and NaCl concentrations used for selection at the germination level. The study was arranged based on a completely randomized design with two factors: NaCl concentration and some chilli pepper genotypes. NaCl solution concentrations consist of five concentrations of N0: 0 g L-1 (EC 291 µS/cm, SAL 0,10), N1: 2 g L-1 (EC 3,71 ms/cm, SAL 2,0), N2: 4 g L-1(EC 6,60 mS/cm, SAL 3,60), N3: 6 g L-1 (EC 9,56 mS/cm, SAL 5,40) and N4: 8 g L-1 (EC 12,45 mS/cm SAL 5,40). The second factor is the genotype of chilli pepper consisting of 22 genotypes. The results showed that the most tolerant genotypes were G4, G7 and G15. Characters that can be used as selection criteria at the germination level are the percentage of germination, radical and hypocotyl length. The concentration of 8 g NaCl L-1 is effectively used to select tolerant genotypes

Abstract

Wheat is a sub-tropical plant that can adapt well at altitudes of 1000 - 3000 m above sea level and requires relatively low temperatures. At this height, wheat crops in Indonesia are unable to compete with horticultural crops with higher economic value. This causes national wheat production to be very low and results in high wheat imports. Therefore, wheat varieties are needed that can grow and develop in Indonesia in the low to medium plains. The study aimed to test the adaptive mutant population descent in the middle plains to prepare multi-location tests and release of varieties. The benefit of this research is obtaining potential strains from high-temperature adaptive wheat mutants in the lowlands. This research was conducted using a randomized block design with three replications. The treatment consisted of 16 M6 Wheat mutants and four comparative varieties. The results showed that the genotypes of wheat mutants that had high production in M6 propagation in the central plains were N 350 3.7.1 (2.74 t. ha-1), N 350 3.6.2 (2.33 t.ha-1) and N 350 3.1.3 (2.26 t.ha-1). Characters that have high heritability values on M6 Number of stomata, chlorophyll index, plant height, number of tillers, productive tillers, rate of seed filling, panicle length, number of seedlings, empty percentage of florets, hollow seed weight, 1000 seed weight, and production

Abstract

The variety of maize in Southwest Maluku (MBD) has an ability to grow in the extremely dry land, especially at Kisar island, because those areas were dominated by dry land. Dry resistance very useful to be used for genetical characterization in order to provide accurate data about the character of local maize Kisar var. Kuning Genjah. To identify the characteristics at the genome level of this local maize variety, one of the molecular methods that can be applied was RAPD molecular method. The advantage of the RAPD marker is it's technically simpler and fast in testing, does not require DNA sequence information, hence this marker becomes widely used, it only requires a small sample of DNA, the primary is commercially available and does not use radioactive compounds. The aim of this study was to find out the bands profile that has the potential to be used as a marker of dry resistance. The method applied was RAPD (Random Amplified Polymorphic DNA) using OPA-02, OPA-07, and OPC-12 primers and produces 22 DNA bands. The measurement of bands by estimating the molecular weight based on marker exponential regression. The polymorphic percentage was 90.9% between var. Kuning genjah and var. BIZI-II-Hybrid. The percentage of polymorphism showed the potential of bands that can be used as molecular markers for markers of dry resistance that can be utilized in plant breeding

Abstract

The purpose of this study was to determine the parameters of soil fertility in rice fields and the effect of soil fertility on paddy productivity in Bogor Regency. This research was conducted in the districts of Cileungsi, Darmaga and Leuwiliang, Bogor Regency. The location selection was done deliberately based on the location of rice production facilities with Ciherang and Inpari varieties. Sampling was conducted at several sampling points at each location. Each sub-district was taken 8 samples or 24 in total, then analyzed in the laboratory. Data processing using multiple regression with a dummy. The results showed that the soil in Bogor Regency was generally acidic, where soil fertility characteristics with organic C content were low to moderate, nitrogen was very low to moderate, P was low to high, K was very low to moderate, CEC was moderate to high, and saturation bases (KB) are moderate to high. Soil biology, namely total bacteria, total fungi, total solvent P bacteria, Azotobacter sp., And Rhizobium sp. Are generally low to moderate. Variable characteristics of soil fertility in the form of organic C, Nitrogen (N), K2O HCl 25%, and CEC significantly influence rice productivity. Soil fertility in the three districts is almost the same and does not affect the productivity of rice fields. While the productivity of rice fields with Inpari varieties is higher than those grown by Ciherang varieties. To increase the productivity of rice fields in Bogor Regency, it is recommended to plant Inpari variety rice by applying N fertilizer
