Abstract

Research aims to test the effectiveness of various types of manure combined with various doses of application for the growth and result of shallot varieties of Palu Valley. This research was designed using factorial randomized block design. The first factor was manure with three types of treatment, namely chicken manure (P1), got manure (P2), cow manure (P3). The second factor was the dose of manure consisting of three types of treatment, namely 10 t ha­­-1 (3,6 kg plot-1) (D1), 20 t ha­­-1 (7,2 kg plot-1) (D2), 30 t ha­­-1 (10,8 kg plot-1) (D3). The results show that the combination of various types of treatment and doses of chicken manure interacts on plat height parameters aged 35 days after planting. The treatment of chicken manure with a dose of 30 t ha-1 gives better results. The single treatment of chicken manure gave better results for the plant height, weight of leaves, root dry weight, leaf dry weight , number of tubers per clump. Single treatment of manure dosage of 30 t ha-1 gave better results on plant height, leaf area , leaf fres weight, leaf dry weight tuber fresh weight per hectare.

Abstract

Clove (Syzigum aromaticum L.) is a native Indonesian plant originating from the Maluku Islands. Until now, cloves have become an essential commodity to support the industry and as sources of farmers' income. An increase followed the increasing area of clove cultivation in problems caused by stem borer attack (Nothopeus Hemipterus). This research aims to obtain information about the magnitude of damage intensity and the extent of stem borer attack. This research was conducted in two village areas: Alakasing village and Solongan village in Central Peling Subdistrict of Banggai Kepulauan District for three months on July 3 - 18, 2017. The observations were carried out on ten plantations owned by farmers: five farms in Alakasing village and five farms in Solongan village. Each sample plot was observed 20 sample plants so that obtained 200 sample plants, the strata of each tree is devided. The highest pest attack area (Nothopeus hemipterus) is in Alakasing Village, plot sample I of the sixth observation is 75%, and the lowest pest attack area (Nothopeus hemipterus) is plot sample V of the sixth observation. Whereas in the observation area of the Solongan Village, the highest percentage of attack area in sample V of the sixth observation is 30% and the lowest percentage of pest attack area (Nothopeus hemipterus) sample plots I and IV respectively 20%. The percentage of damage intensity caused by clove stem borer (Nothopeus hemipterus) in the Alakasing village area was 7.56%, while the percentage of damage intensity in the Solongan Village area is 3.26%.

Abstract

This research was conducted to determine nutrient status and soil fertility levels in Dolo District, Sigi Regency, map the soil nutrient status and soil fertility levels in Dolo District, Sigi Regency and as a reference for recommendations for land management in accordance with nutrient status and fertility levels in the three uses. different lands in Dolo District, Sigi Regency. This research was conducted in Langaleso Village and Kabobona Village, Dolo District, Sigi Regency, taking soil samples on cocoa land, deep coconut land and dry land in Dolo District, Sigi Regency. This type of research is a survey method and the data is presented descriptively. By trying to conduct observational surveys and soil sampling by purposive sampling. Soil samples were taken from 3 types of land use, namely cocoa land (K), Kelapa Dalam land (P) and dry land (T). Soil samples were taken at a depth of 0 - 20 cm and 21 - 40 cm. Where each land use is taken at two different locations, each two points of soil sampling and composited so that a total of 12 soil samples are obtained. The results of the research showed that the nutrient status that became an obstacle in soil fertility in Dolo District, Sigi Regency was Soil Reaction (pH) slightly acidic, Cation Exchange Capacity (CEC), C-organic, Nitrogen (N), Phosphorus (P), Potassium ( K) is classified as moderate, and base saturation (KB) is low so that the level of soil fertility on coconut, cocoa and dry fields in Dolo District, Sigi Regency is moderate and has unhealthy/less fertile soil quality.

Abstract

Central Sulawesi's 2018 earthquake, liquefaction, and tsunami caused liquefaction in Palu City's Balaroa and Petobo neighbourhoods. Land surface changes affected agricultural land area and soil fertility, which can affect farmers' income. Soil fertility indicates its nutrient-providing capacity. This study aims to assess agricultural land fertility, farmer income, and the best ways to recover from natural disasters. This descriptive study included all Petobo farmers affected by the earthquake and liquefaction. Purposive sampling tested 25 respondents. The field survey collected soil samples at coordinate points. Twelve soil samples were taken from six points at 20 cm and 40 cm depths. The samples were analysed at Tadulako University's Environmental and Natural Resources Analysis Laboratory. The results showed that Petobo Village's liquefaction-affected and unaffected areas had low fertility due to low C-organic and Potassium content, which prevented plants from using soil nutrients. Low soil fertility reduces crop production. Farmers earn an average of Rp. 1,422,857 per hectare, up to Rp. 4,633,929 per season per hectare. To increase soil fertility, farmers can use compost, manure, crop residues like legume plant stover, rice straw, and chemical fertilisers according to dosage.
