Abstract

Efforts to improve tomato production can be done with the use of organic fertilizers derived from agricultural waste, manure, green manure, manure-human waste, and compost as a substitute source of nutrients. This study aims To determine the best combination between provision of organic fertilizer POC and Rice Husk Ash On the Chemical Properties of the Soil On the Tomato Plant. This research used randomized block design factorial consisting of 2 treatment factors, namely : the Concentration of POC NASA (N) consists of 4 levels, namely: N0 = 0% ( control), N1 = 1 cc/ liter of water, N2 = 2 cc/ liter of water, N3 = 3 cc/ liters of water. Organic fertilizer Rice Husk Ash (A) which consists of 3 levels, namely :A0 = 0 tons/ ha, A1 = 15 tons/ha (158 g/polybag), A2 = 30 ton/ha (316 g/polybag). The test map used is the Duncan Multiple Range Test (DMRT). As for the observed parameters, namely soil chemical properties include soil pH Methods Elektrometri, C-organic (%) Method of Walkley and Black, P-Available (%) Method of Bray II. The results showed that the Provision of Liquid Organic Fertilizer NASA and as much as 2 cc/ liter of water is able to increase the soil pH and C-organic. Provision of 30 ton/ha or equivalent to 316 g/polybag Rice Husk Ash is able to increase P-available and C-organic.

Abstract

In running a farming business in an agricultural production organization, farmers as actors and implementers carry out organizing agricultural cultivation, labor, and capital aimed at production in the agricultural field, whether based on profit or not. Cultivation of soybean (Glycine max L.) is the main commodity of legumes which is a national mainstay because the source of vegetable protein is important for food diversification in supporting national food security. Many factors influence farmers in farming, especially in terms of prioritizing optimal production results, including economic factors with capital control so that the expectation of greater profits from farming will be chosen when compared to other forms of farming. The research objective was to determine the level of farmer adoption of soybean cultivation technology and to determine the socio-economic effect of farmers on soybean cultivation technology in Sidua Dua Village, Kualuh Selatan District, North Labuhanbatu Regency. This research uses descriptive or quantitative methods by conducting survey methods. From the results of the study, it was found that the Farmer's Adoption Rate of Soybean Cultivation Technology (Glycine Max L) on the Influence of Socio-Economic Aspects in Kualuh Selatan District, North Labuhanbatu Regency was classified as moderate, soybean cultivation had not followed all the components of cultivation technology recommended by Field Agricultural Instructor and the level of adoption of soybean cultivation in Sidodadi village is influenced by age, level of education, length of farming, frequency of attending counseling.

Abstract

Seedlings which look prima is a prerequisite for the success of oil palm cultivation. Besides, because of the factors in the pre-nursery genetic, the provision of nutrients in early growth seedlings has an important role performance determine the appearance of the seedlings thoroughly. This study aims to determine the influence of the growth of oil palm seedlings at each concentration of organic fertilizer tithonia and fertilizer of urea for pre-nursery. The experiment was carried out from January to Agustus 2019 in the Experimental Garden of the Faculty of Science and Technology, the University of Labuhanbatu Rantauprapat with a height of 13 meters above sea level. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The first factor includes the dose of Organic Fertilizer Tithonia (ton/ha) comprising of three standards, namely T0 = 0 ton/ha, T1 = 10 ton/ha, T2 = 20 tons/ha and the second factor was fertilizer dosage Uera which consists of four levels, namely U0 = 0 kg/ha, U1 = 100 kg/ha, T2 = 200 kg/ha, U3 = 300 kg/ha. The experimental results show that there are significant interactions of organic fertilizer Tithonia with fertilizers urea on plant height (cm) and leaf area of oil palm seedlings (cm2). Treatment of organic fertilizer tithonia 20 tons/ha with fertilizer urea 300 kg/ha yield plant height and leaf area of oil palm seedlings the best for pre-nursery.

Abstract

Coffee is one of Indonesia's main economic activities for foreign exchange. An increase in exports of 8.11%, and a decline in imports of 58% in 2019, opened up export opportunities and large domestic markets. The government has implemented efforts to improve coffee farmers' welfare, one of which is agricultural business partnerships that can solve smallholder problems in developing countries and expand subsistence or traditional agriculture to high production value and export-oriented. This research aimed to analyze (1) the factors influencing coffee farmers' participation in agricultural partnerships and (2) the impact of the agricultural partnership on coffee farmers' performance in Simalungun Regency, North Sumatra Province. The Propensity Score Matching (PSM) technique analyzed the partnership's influence on coffee farming and agricultural income, productivity, and prices.  The results showed that number of dependents  household members and land area influence farmers' partnership participation. Participation increases coffee farming and agricultural income, productivity, and prices.

Abstract

The approach or method for evaluating land resource potential is a method of land evaluation. The expected production value that may be obtained, as well as the information and/or direction of land use required, will be provided by the results of the land evaluation. .Evaluation of the characteristics of the level of land suitability in the area is carried out to analyze improvement efforts aimed at increasing productivity and produce maps of actual land suitability and potential land suitability for superior commodities in the sub-district. Land use in South Kualuh District needs to be supported by land suitability information. Survey methods used. Land units are based on land maps, slope, elevation and land cover. The process of comparing (matching) is an analysis method.The results of the research show that the level of land suitability for corn plants. The condition of the actual land to become potentially suitable for cultivation in Kualuh Selatan District for corn plants is the limiting factor in nutrient availability (na), temperature regime (tc), rooting media (rc), nutrient retention (nr ) and the danger of erosion (eh). Improvement efforts that can be made include making drainage, liming CaCO3, adding organic material, making terraces or planting parallel to the contour and fertilizing. The temperature regime cannot be repaired

Abstract

Good seed growth is a factor in the success of oil palm cultivation due to genetic pre-nursery factors in the field, so that the provision of nutrients in the initial seed growth plays an important role in determining the overall appearance of the seedlings during its growing period. This study aims to determine the effect of oil palm seed growth by applying Uera fertilizer and rice husk charcoal organic fertilizer during the pre-nursery in the field. The experiment was carried out from October 2020 to May 2021 in the experimental garden of the Faculty of Science and Technology, Labuhanbatu University, Rantauprapat at an altitude of 13 meters above sea level. The experimental design in this study was a randomized block design with a factorial pattern that was repeated three times. The first factor is the dose of Uera fertilizer which consists of four levels, namely U0 = 0 kg / ha, U1 = 100 kg / ha, U2 = 200 kg / ha, U3 = 300 kg / ha and the second factor includes the dose of Rice Husk Charcoal Organic Fertilizer (ton / ha) consists of three levels, namely A0 = 0 ton / ha, A1 = 100 ton / ha, and A2 = 200 ton / ha. The results of the experiment showed that there was an interaction effect of uera fertilizer and rice husk charcoal organic fertilizer on plant height (cm),leaf area of ​​oil palm seedlings (cm2), in the number of leaves (leaf) and accretion hump diameter (mm). Treatment of urea fertilizer of 300 kg / ha and organic fertilizer of rice husk charcoal as much as 20 tons / ha produced plant height and leaf area during the pre-nursery
