Vermicompost also contains many of the nutrients available to plants and increases soil porosity, soil aeration, and humidity, and controls soil erosion so that it can help in buffering toxins for plants and promoting plant growth. Corn is a cereal crop that is the second most important food crop in Indonesia besides rice. The volume of corn imports is higher than exports, this is due to the high demand for corn but domestic corn production has not been able to fulfill it. The experimental design used was a Randomized Completely Block Design (RCBD), seven levels of vermicompost doses, namely 0; 2.5; 5.0; 7.5; 10; 12.5; and 15 tons ha-1) each repeated 4 times. This study aims to determine the dose of vermicompost fertilizer that can improve the properties of Entisols and yields of maize (Zea mays L.). The application of vermicompost fertilizer with seven dose levels had a significant effect on N nutrient levels in coastal Entisols. Doses of vermicompost were able to increase dry stover weight, cob weight with husk, and cob weight without husk of corn plants.","PeriodicalId":202555,"journal":{"name":"TERRA : Journal of Land Restoration","volume":"591 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130672109","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}

Thus, studies related to socio-economic aspects and decision behaviors of smallholder farmers prior to the implementation of communal degraded land restoration are scanty. This study assessed the socio-economic characteristics and decisions making of smallholder farmers in degraded communal land restoration. The kebele under study was purposively selected near the communal degraded land for future intervention. Cross-sectional data were collected from 94 smallholder farmers selected using a systematic random sampling method. Binary logit was employed to see determinants of farmers’ decision to participate in the rehabilitation of communal degraded land. The study result revealed that attitude towards village leaders and labor availability positively determines farmers’ decision, while credit to access and absence of local institutions negatively influence the willingness of farmers to participate in communal land restoration. It seems that the socio-economic base of smallholder farmers did not have a strong linkage for their decision in the land restoration effort. The findings generally suggest that there should be locally based capacity building of the community in a participatory approach for land restoration efforts. \u0000 ","PeriodicalId":202555,"journal":{"name":"TERRA : Journal of Land Restoration","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115409434","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}

The treatments were (1) 1.0 g urea, (2) 0.5 g urea + 1.15 g OMF, (3) 0.5 g urea + 2.30 g OMF, (4) 0.5 g urea + 3.45 g OMF, and (5) 0.5 g urea + 4.60 g OMF. The results showed that combined application of 0.5 g urea + 4.60 g OMF produced the highest values of plant height (30.60 cm), number of leaves (30.90), fresh weight of tubers per clump (30.90 g),  dry tuber weight per clump (24.3 g), and tuber diameter (16.25 mm). The incorporation of zeolite and palm oil compost in urea reduced the application rate of urea up to 50% without reducing the growth and yield of shallot.

Entisols have the following characteristics: loose soil aggregate, sensitive to erosion, and low levels of nutrients, organic matter, water holding capacity, and soil fertility. The nature of this Entisol is less able to produce maximum upland rice production. The technology used to overcome this problem is by applying macro and micro fertilizers to the soil, which is planted with upland rice seeds, inoculated with biological fertilizers so that it is hoped that upland rice production can be maximized. The purpose of this study was to obtain high upland rice production in coastal areas. The research was carried out from June to December 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City. The research location is located at coordinates S 03?45'23'' E 102?15'41''. The experimental design used was Completely Randomized Block Design (CRBD) with 2 factors, namely types of fertilizers and varieties of upland rice. The first factor consists of P0 = No fertilizer; P1 = compound micro fertilizer; P2 = Fertilizer recommended for upland rice from the Institute for Agricultural Research and Technology). The second factor consists of V1 = red upland rice; V2 = white upland rice) The results showed that there was an interaction between the type of fertilizer and upland rice varieties on soil pH (KCl 1:2.5 w/v). the interaction of microfertilizers with white upland rice varieties resulted in the highest soil pH (5.06). The best type of fertilizer is micro-compound fertilizer which produces soil pH (KCl 1:2.5 w/v), P nutrient uptake, the highest root colonization and the highest number of production tillers and the highest grain weight per plant and upland rice yield per plot.
