Abstract

Various crop commodities are grown in Ngawonggo Village with various land uses, including rice fields, dry fields and agroforestry which are dominated by intensive agriculture. As a result, this agricultural pattern can potentially cause land degradation. One of the technological inputs in improving sustainable crop production systems is the application of mycorrhizal biofertilizers. This study aims to determine the level of population, mycorrhizal colonies and types of spores and the factors that influence them in rice fields with rice (Oryza sativa), dry fields with sengon (Paraserianthes falcataria), and agroforestry with coffee (Coffea sp.) and Durian ( Durio zibethinus). The study used a randomized block design with sampling on three land uses, with 5. The results obtained only one type of mycorrhizal spore of Glomus sp. on all land uses. The highest number of spores was in agroforestry land use, as much as 102 g-1 soil, and the lowest was in rice fields, as much as 10 g-1 soil. Mycorrhizal colonies on plant roots were the highest in agroforestry land use, it was found that 42.77% of coffee roots were colonized by mycorrhizae, followed by durian with a colonization proportion of 42.29%, rice fields with commodities had the lowest colonization proportion of 16.21%.

Abstract

Mycorrhizae is a symbiotic relationship between fungi and plant roots that is mutually beneficial. Mycorrhizae can be found in almost all soil types and generally do not have a specific host, but certain factors affect the population level and composition of arbuscular mycorrhizal species, such as plant characteristics and soil chemical properties. This study aimed to determine the density of spores and the percentage of mycorrhizal colonies on several food crops on agricultural land in Jabung District and their relationship to soil chemical properties such as pH, organic-C and available P. The research was conducted from February 2021 to October 2021. Sampling was carried out by purposive sampling based on the grouping of food plant species with six replications. Laboratory analysis was conducted in Biology and Chemical Laboratory, Department of Soil Science, Faculty of Agriculture, Brawijaya University. The results showed that the number of mycorrhizae spores per 100 g of soil was sweet potato (14.17 spores), rice (26.50 spores), cassava (70 spores), and maize (89.17). The percentage of mycorrhizal colonies on sweet potato (33.97%), cassava (50.67%), and rice (45.52%) were in the high category, while the percentage of mycorrhizal colonies on maize (63.68%) was in the very high category. Several mycorrhizae were found, including Glomus sp., Acaulospora sp., and Gigaspora sp.

Abstract

Mycorrhizae is a mutualistic symbiotic relationship between fungi and plant roots, and soil characteristics influence the performance of this symbiosis. Biopore Infiltration Hole is a vertical hole into the soil with a diameter of about 10cm and at a depth of ±100 cm in the soil for air infiltration, which is helpful in reducing the occurrence of excessive air puddles. This research was conducted to determine the effect of soil properties such as pH, total N, available P, CEC and texture on the number of spores and root colonies by arbuscular mycorrhizae on the effect of biopore infiltration holes with the addition of organic matter. The results showed that the highest number of arbuscular mycorrhizae spores and root colonies was in the biopore infiltration holes with goat manure, namely 16.3 spores 100 g-1 soil and 66.22% root colonization. The arbuscular mycorrhizal genera found included Glomus, Acaulospora, Scutellospora, and Gigaspora. The number of spores and soil properties that were positively correlated were pH (r=0.45), organic C (r=0.945**), total N (r=0.716**), available P (r=0.922**), dan CEC (r=0.894**).
