Agricultural land is a source of food availability, however it is one source of GHG emissions, especially methane and nitrous oxide. Integration management of land, water, and plants in an integrated manner can be an effort to reduce the impact of climate change. This paper aims to inform the technologies to reduce emissions of methane and nitrous oxide in rice fields. One of the technologies to mitigate greenhouse gas emissions on agricultural land is through the use of natural materials as an inhibitor for the formation of methane and nitrous oxide in the soil due to the content of secondary metabolites in natural ingredients. Natural materials can simultaneously increase nitrogen nutrient uptake and improve crop yields. The methane production in rice fields is suppressed by more than 30% by coconut fiber, turmeric rhizomes, leaf of Ageratum conyzoides, and the leaf of Cosmos caudatus; while application of Cosmos caudatus and Ageratum conyzoides can also reduce the production of nitrous oxide more than 20%, respectively.","PeriodicalId":53109,"journal":{"name":"Agric","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84685603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted from March to November 2013 at the Soil Testing and Research Laboratory, Indonesian Soil Research Institute. The soils were collected from the Banten, West Java, and Central Java. The experiment was carried out by the statistical method of two means. The soil used was 100 g of wind-dried soil, which was analyzed by extracting Morgan Venema, Wet Ashing HNO3 and HClO4, Morgan Wolf. The observation was made on the chemical properties of the soil with various concentrations and several extracts. The best extraction was determined based on the value of R2 and the significance of the regression equation between the results of soil analysis of several extractions with the percent yield and nutrient uptake as measured by ICP and AAS tools. The experimental results showed that the ICP-OES and AAS tools could be used with some extractions. This was indicated by the significant regression coefficient data on various extraction. The parameters K, Ca, Mg, Fe, Mn, Cu, and Zn were obtained in the HNO3 and HClO4 extraction, which could be said to be the best extractions used in ICP and AAS equipment. Morgan Wolf extract obtained insignificant results on Cu measurements. This showed that the Cu parameters in the Morgan Wolf extract were not suitable for analysis with ICP.","PeriodicalId":53109,"journal":{"name":"Agric","volume":"339 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76391520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the 28 isolates that were successfully isolated from the Kamba local rice rhizosphere, 10 isolates had the potential to produce siderophores with different morphological characters. The test was carried out to see the bacterial isolates capabilities to produce siderophores from two types of siderophores namely catechol and salicylate types. For the catechol type, the highest concentration of siderophore was found in the KBA8 bacterial isolate with 10.990 mg L-1, while the lowest was in the KBA1 bacterial isolate with only 5.876 mg L-1. The salicylate type siderophore with the highest concentration produced 9.493 mg L-1 was from the RKGU15 isolate and the lowest was found in KBU14 isolate which produced only 2.994 mg L-1. The isolates included in the Gram-positive group were 4 isolates while the Gram- negative group were 6 isolates and 90% isolates were able to produce the enzyme catalase.

Biofertilizers can reduce the use and adverse effects of inorganic fertilizers. Arbuscular Mycorrhizal Fungi (AMF) is one of the biofertilizers that can help plants absorb nutrients and increase plant resistance to various environmental stresses. This study aimed to examine the role of AMF (as biofertilizer) and inorganic fertilizers in increasing the production of oil palm flower bunches in Ultisol. This experiment is a factorial experiment using a Randomized Block Design. The first factor is the application of biofertilizers, which consists of two levels without biofertilizers (AMF) and with biofertilizers (AMF). The second factor is the dose of inorganic fertilizer, composed of 5 levels, no inorganic fertilizer, 25, 50, 75, and 100% recommended doses of inorganic fertilizer. The variables observed were the number of sheaths, the percentage of broken sheaths, the number of male flower bunches, the number of female flower bunches, the percentage of male and female flower bunches, sex ratio per plant, and AMF colonization. The results showed that AMF biofertilizer saved 25% of inorganic fertilizers and increased 29.33% of female flowers production. The highest production of oil palm flower bunches was obtained from the application of AMF biofertilizer and 75% of inorganic fertilizers (1.5 kg Urea, 1.1 kg SP-36, 1.2 kg MOP, 0.7 kg Kisserite per plant). Oil palm with AMF had a higher average sex ratio than plants without AMF biofertilizers.

Seed health testing is required to detect the presence of pathogens or seed health status. To support the program of activities of the Ministry of Agriculture in the development of local rice, it is necessary to start by evaluating the health of seeds in the local paddy varieties.
