The aims of this study is to determine the effect of several fertilizer formulas on soil chemical properties and yield of green mustard (Brassica juncea L.) in Subak Tegal Lantang, West Denpasar District. This study used a Randomized Block Design (RBD) consisting of 6 treatments including controls and repeated 4 times with a total of 24 treatment plots. Fertilization treatment consists of three types of fertilizers, namely organic fertilizer, inorganic fertilizer, and biofertilizer. The fertilizer formula tested consisted of P0 = control (without fertilizer), P1= 5 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1, P2= 5 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1 + biofertilizer (1 cc / liter water / plot), P3= 10 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1, P4= 10 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1 + biofertilizer (1 cc / liter of water / plot), P5= biofertilizer with a concentration of 1 cc / liter of water / plot. The data from the observed parameters then analyzed statistically using analysis of variance (Anova) to determine the significance of the treatment. If it has a significant effect on the parameters observed, then it will be followed by the LSD test at the 5% real level. The results of study showed that the fertilizer formula treatment had a very significant effect on organic-C (P <0,01) and significantly affected the plant fresh weight (P <0,05), but had no significant effect on the acidity (pH), total-N, available-K, available-P, cation exchange capacity, base saturation, plant height, number of leaves, and plant dry weight. The P4 fertilizer formula gave the highest increase in soil organic-C content significantly by 2.99% or an increase of 66% compared to the control and gave the highest yield of fresh greens mustard by 23.64 tons ha-1.

Digestate from biogas production can be recycled to the soil as conditioner/fertilizer improving the environmental sustainability of the energy supply chain. In a three-year maize-triticale rotation, we investigated the short-term effects of digestate on soil physical, chemical, and microbiological properties and evaluated its effectiveness in complementing the mineral fertilizers. Digestate soil treatments consisted of combined applications of the whole digestate and its mechanically separated solid fraction. Digestate increased soil total organic C, total N and K contents. Soil bulk density was not affected by treatments, while aggregate stability showed a transient improvement due to digestate treatments. A decrement of the transmission pores proportion and an increment of fissures was observed in digestate treated soils. Soil microbial community was only transiently affected by digestate treatments and no soil contamination from Clostridiaceae-related bacteria were observed. Digestate can significantly impair seed germination when applied at low dilution ratios. Crop yield under digestate treatment was similar to ordinary mineral-based fertilization. Overall, our experiment proved that the agronomic recycling of digestate from biogas production maintained a fair crop yield and soil quality. Digestate was confirmed as a valid resource for sustainable management of soil fertility under energy-crop farming, by combining a good attitude as a fertilizer with the ability to compensate for soil organic C loss.

ABSTRACT Pigeon pea is an important protein source grown in several tropical and sub-tropical countries, and is considered a multi-purpose plant that is resistant to the conditions of the Brazilian Cerrado. Among the possible uses for cowpea, its use as a green manure, increasing soil nitrogen content through the association with diazotrophic bacteria, generically known as rhizobia, is noteworthy. The present work aimed to evaluate the efficiency of Rhizobium strains isolated from cowpea plants in the development of pigeon peas cultured in Red Latosol. The experiment was conducted in a greenhouse, using a completely randomized design with seven treatments and four replications. Treatments consisted of inoculation with four Rhizobium strains (MT8, MT15, MT16, and MT23) and one commercial inoculant comprising Bradyrhizobium spp. strains BR 2801 and BR 2003. There were two controls, one absolute (without inoculation or nitrogen fertilization) and the other with nitrogen fertilization. Each experimental plot consisted of an 8-dm3 vase containing three plants. Analyzed variables included plant height, SPAD index, number and dry weight of nodules, and shoot and root dry masses. Pigeon peas responded significantly to inoculation treatment, since all the plants inoculated with Rhizobium strains isolated from cowpea strains showed results similar to plants in the nitrogen control and commercial inoculant treatments. This demonstrates a favorable plant-bacteria interaction, which can be utilized as an alternative nitrogen source for pigeon peas.

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.
