Community service is implemented in Tegalmengkeb Village of East Selemadeg District Tabanan, Bali. Thepurpose of this dedication improves the understanding and skills of farmers in the application of biofertilizeron rice crops. The method used in this activity is counselling with lectures and discussions, followed bytraining on the manufacture of local microorganisms (MOL) and the application of biofertilizer on rice crops.It is hoped that the community can apply biofertilizer technology that can improve rice crop yield andfarmer's income. The results of the training increase the understanding of farmers about biofertilizer by 30%,know about the biofertilizer and the role of biofertilizer as fertilizer of soil and plants. Increased farmers'skills in the production of local microorganisms (MOL) and can apply Egary biofertilizer to rice crops.
Dynamics Of Ammonium And Nitrate In Semi Organic Rice Fields For Local And Hybrid Rice Plants In Subak Jatiluwih, Tabanan Regency. The study was conducted to determine the dynamics of ammonium and nitrate and time subsequent fertilization in paddy fields with local and hybrid rice. Soil and water samples in two replications were taken each the two paddy fields periodically, namely during the tillage (DTT), 0, 7, 14, 21, 28, 42, 56, 70, 84, 98, and 112 days after planting (DAP). Ammonium and nitrate levels were analyzed by Macro Kjeldahl method. The results showed that the dynamics of ammonium and soil nitrate were different in two rice varieties. The highest ammonium content of local rice at the age of 7 DAP rice and the highest nitrate content at age 14 DAP. Ammonium and nitrate levels are highest in hybrid rice fields at 28 DAP rice age. The lowest ammonium and nitrate levels in two different varieties of rice land, namely the lowest local rice varieties at the age 28 DAP, whereas in hybrid rice land at age of 98 DAP. The results of this study indicate that supplementation of urea can be carried out at the age of 21 and 98 DAP for local rice varieties, and at the age of 14 DAP and 42 DAP for hybrid rice varieties.
The Effect of Bamboo Biochar Size and Urea Fertilizer Dosage on Fertilizer Efficiency and Yield of Green Mustard (Brassica juncea L.) in Sandy Soil. Biochar is charcoal produced from incomplete combustion (carbonization). Biochar is a soil amendment agent that has long been known in agriculture which is useful for increasing soil productivity. This study aims to determine the effect of bamboo biochar size and urea fertilizer dosage on the efficiency of urea fertilizer and yield of green mustard (Brassica juncea L.). This research was conducted from May 2020 to September 2020 at the Experimental Garden of the Faculty of Agriculture, and at the Laboratory of Soil and Environmental Sciences, Faculty of Agriculture, Udayana University. The research design used was a completely randomized design (CRD) with 2 factorials and 3 replications. The treatment factors consisted of P0 = 0kg urea (control) (0 grams / pot), P1 = 100kg urea / ha (0.2 grams / pot), P2 = 200kg urea / ha (0.4 grams / pot), P3 = 300kg urea / ha (0.6 gram / pot), B1 = 0.25-2.00 mm, B2 = 2.38-2.83 mm, B3 = 2.83-3.36 mm. The parameters observed were levels of ammonium, nitrate, soil pH, microbial population, soil respiration, crop yields including fresh weight and oven dry weight of the plant. The results of the analysis showed that the effect of biochar and urea fertilizers interacted very significantly with the parameters of the microbial population and had no significant effect on the parameters of ammonium, nitrate, soil pH, soil respiration, plant fresh weight, plant dry weight, root fresh weight, root dry weight and efficiency. fertilizer. Biochar treatment has a significant effect on biological factors and fertilizer treatment affects soil chemical properties, crop yields are influenced by a single factor.
The Utilization of Biochar as a Carrier of Rhizobium for the formation of root nodules and Yield of Soybean (Glycine max L. Merril). This study aims to determine the effect of the type of raw materials and particle size of biochar as a Rhizobium carrier on the formation of nodules in soybean plants. This research was conducted from September to November 2020 at the Experimental Station and Laboratory of Soil and Environmental Sciences, Faculty of Agriculture, Udayana University. The research design used was a randomized block design with nested patterns with 2 factorials and 3 replications. The treatment factors consisted of B1 = bamboo biochar, B2 = albasia wood biochar, B3 = corncob biochar, B4 = young coconut skin biochar, P1 = (0,15-0,50 mm), P2 = (>0,50-1,68 mm), P3 = (>1,68-3,36 mm). The parameters observed included effective nodule, nodule size, total bacterial population, ammonium, nitrate, and plant yield. The result of the analysis showed that the type of biochar raw materials had a very significant effect on the parameters of effective nodules, nodules size, total bacterial population and plant yield, but had no significant effect on soil chemical parameters. The treatment of biochar particle size had a very significant effect on the parameters of effective nodules, total bacterial population, and plant yield, and had a significant effect on the size of nodules, but had no significant effect on soil chemical parameters. The conclusion of this study is that the type of raw material for albasia wood biochar is effective as a Rhizobium carrier, which is indicated by the high number of effective nodules, nodules size and total bacterial population of 0,15-1,68 mm particles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
