UJI KETAHANAN MELADA TERHADAP CEKAMAN KEKERINGAN
Get PDFPepper is one of the important commodities in Indonesia. The main obstacles In pepper cultivation is basal stem rot. It can be solved by grafting pepper plants on rootstock that is resistant to that disease. Melada plants (Piper colubrinum Link) are considered resistant to stem rot disease and are also resistant to flooding and drought. The aim of this research was to test the resistance of melada plants to drought stress. The research was carried out using a completely randomized design consisting of five treatments with five replications, and every treatment unit consisting of three plants. Melada cuttings are planted in plastic pots. After 5 months, the seedlings were treated with drought stress by irrigating using a Polyethylene glycol (PEG) solution with concentrations of 0%, 10%, 15%, 20%, and 25% for two months. Data were analyzed using analysis of variance. The results showed that drought stress treatment reduced plant growth in the variables leaves number and fully opened leaf area. Melada plants are resistant to drought stress up to an osmotic pressure level of -4.5 bar, equivalent to 15% PEG. Apart from reducing growth, drought stress causes necrotic damage on the leaves starting from the edges of the leaves
PENGARUH KOMBINASI PUPUK KANDANG KAMBING, PUPUK HAYATI DAN KAPUR TERHADAP PERTUMBUHAN DAN HASIL DUA VARIETAS KUBIS BUNGA PADA LAHAN SULFAT MASAM DENGAN SISTEM BUDIDIDAYA JENUH AIR
Get PDFThe Cauliflower (Brassica oleraceae var botrytis L.) is a potential horticultural commodity that has great prospects for intensive development in the lowlands. The vitamin and fiber content in cauliflower is so abundant that it is very good for the human body. Cauliflowers can be cultivated on several types of mineral soil, one of which is acid sulfate mineral soil. Problems in acid sulfate mineral soils contain high clay, high soil acidity, a pyrite layer, and nutrient deficiencies. Efforts can be made to support the growth of cauliflower by applying a soil saturated culture system, providing combination of goat manure + bioboost + dolomite, and using lowland cauliflower varieties. The research location is at Golden River Camp Kalimas Village, Sungai Kakap District, Kubu Raya Regency. The research took place from July to November, 2023. The research design used was a Split Block Design, consisting of 2 treatment factors and repeated 3 times and consisting of 4 sample plants. The first factor is the variety as the main plot with 2 treatment levels (Larissa and Snow White) and the second factor is the combination of ts (goat manure ton/ha + bioboost ml/l + dolomite ton/ha) as a subplot with 4 treatment levels. The variables observed in this study consisted of the number of leaves (strands), leaf area (cm2), fresh weight of upper plants (g), dry weight of upper plants (g), age of flower appearance (hst), crop diameter (g) and crop weight (g). The results showed that there was a different response between the two varieties and the combination of goat manure + bioboost + dolomite on the growth and yield of cauliflower, The Larissa variety showed better growth and yield when compared to the Snow white variety and the combination of goat manure 10 tons/ha + bioboost 15 ml/l + dolomite 2 tons/ha can increase the growth and yield of cauliflower better than other ts combinations on tidal acid sulphate soil with soil saturated culture system
PENGARUH PEMBERIAN BIOCHAR TERHADAP KETERSEDIAAN HARA N, P, K DAN PERTUMBUHAN TANAMAN JAGUNG DI TANAH GAMBUT
Get PDFCorn (Zea mays L.) is an important commodity in West Kalimantan as a second food commodity after rice as a carbohydrate. Peat soils that are easily leached result in low availability of nutrients in the soil. This study aims to determine the effect of giving biochar from corn cobs and rice husk biochar on the availability of N, P, and K nutrients, as well as the growth of corn plants in peat soils. This study used a Randomized Block Design (RAK) with 8 treatments, namely without corn cob biochar (J0), corn cob biochar 500 g/plot equivalent to 5 tons/ha (J1), corn cob biochar 1000 g/plot equivalent to 10 tons/ha (J2), corn cob biochar 1500 g/plot equivalent 15 tons/ha (J3), without rice husk biochar (S0), rice husk biochar 500 g/plot equivalent 5 tons/ha (S1), rice husk biochar 1000 g/plot equivalent to 10 tons/ha (S2), rice husk biochar 1500 g/equivalent plot 15 tons/ha (S3) with 4 replications and each plot consists of 8 plants, so that there are 32 experimental plots. The results show that the application of various doses of corncob biochar and rice husk biochar did not show a significant effect on soil pH, total soil N, soil available P, soil exchangeable K, plant height, and stem diameter

Get PDFfarmer satisfaction in obtaining services from their field extension workers. An agricultural extension worker must know the level of satisfaction of the extension target, namely farmers in their work area, in order to improve the quality and performance and success of their extension activities in the future. For farmers in Humboto Village, Uepai District, Konawe Regency, the presence of agricultural extension workers is highly expected, especially to help farmers solve the problems they face, but in reality, not all farmer problems can be resolved. Agricultural extension workers in Humboto Village, Uepai District, number 1 extension worker who also works in other villages because the extension workers from the State Civil Apparatus (ASN) are still very few, namely 8 people who have to work in 18 villages in Uepai District (BPP Uepai District, 2024). The lack of extension workers with a fairly large area of work can affect the quality of work (performance) of agricultural extension workers. Therefore, the purpose of this study was to analyze the level of farmer satisfaction with the performance of extension workers in Humboto Village, Uepai District. Uepai, Konawe Regency. The attributes used to measure the level of farmer satisfaction are 5 attributes with 20 items. Data analysis used a score based on a Likert scale with 5 categories, namely very satisfied, satisfied, quite satisfied, dissatisfied and very dissatisfied. The results showed that the level of farmer satisfaction in Humboto Village, Uepai District, Konawe Regency is in the category of quite satisfied with the performance of PPLKey-words: satisfaction; performance; PP
