Farmer Group Training in Utilizing Bokashi for Cultivating Vegetable Crops
No full textSuboptimal land use by farmers for crop cultivation activities faces obstacles including less fertile soil conditions, low soil pH and iron poisoning. To overcome this problem, efforts are needed to increase farmers' knowledge and skills, especially in the use of organic fertilizers, one of which is bokashi. The aim of this PKM activity is to increase the knowledge and skills of partners in using bokashi for plant cultivation. To achieve this goal, the method used in implementing this PKM activity is: 1). Counseling is carried out face to face with partner groups. Extension material regarding organic fertilizer, making and applying bokashi, cultivating leaf lettuce, and farmer group management; 2). Demonstration/practice of bokashi application on growing media 3). Mentoring, mentoring activities are carried out through visits to partner locations to see the results of bokashi practices that have been carried out, and holding discussions with partners. The problem with the production aspect in this farmer group is: the use of bokashi for cultivating vegetable crops is still not optimal. The solution offered to overcome production aspect problems is to transfer knowledge and technology for the use/application of bokashi for the cultivation of vegetable crops through the use of agricultural waste and available livestock materials to be used as substitutes/substitutes for inorganic fertilizers. Through the PKM activities that have been carried out, it can be seen that there has been an increase in participants' knowledge about bokashi from the initial condition of 36.63% to 94%
Effect of Combination of Poultry Manure and Rice Husk Biochar on Soil Fertility and Rice Plants
No full textRice plants occupy a strategic position as a staple food producer for the people of Indonesia. Faced with limited suboptimal soil fertility, especially low levels of nutrients and soil pH, the use of organic fertilizers combined with local ameliorants is one solution to increase soil fertility. The purpose of this study was to obtain a combination of chicken or quail manure with rice husk biochar, which can reduce the use of inorganic fertilizers (urea, SP-36, and KCl). This study used a completely randomized design (CRD) consisting of 7 treatments (A, B, C, D, E, F, and G) which was a combination of 100% to 25% inorganic fertilizer of the recommendations, chicken manure or bird manure quail 5 tons/ha, and rice husk biochar 5 tons/ha. The parameters observed were plant height, total chlorophyll, seed dry weight, soil pH, soil NPK content, and Al-dd content. Observational data were analyzed with the F test at the 5% level then further tests were carried out using the Honest Significant Difference (HSD) test. The results showed that the treatments had a very significant effect, namely C, D, and E treatments resulted in a decrease in Al-dd, and an increase in K and had a significant effect on rice plant height. It was concluded that a combination of 5 tons/ha of chicken manure or quail manure with 5 tons/ha of biochar could increase soil fertility and rice plant height during the vegetative period and could substitute inorganic fertilizers up to 50% of the recommended dose
