Abstract Acacia (Acacia mangium), jatropha (Jatropha curcas), and cassava (Manihot esculenta) were cultivated in a greenhouse to see how organic amendments affected plant survival and accumulation of cadmium (Cd) in plant tissues. The study plants are bioenergy crops, which are advantageous to phytomanagement because they provide a significant economic benefit to local residents and farmers in the agricultural sector while also simultaneously reducing Cd entry into food webs through consumption. In this study, bone meal/bat manure and leonardite/bat manure were the key organic amendments that promoted the best growth performances in acacia (growth rate in dry biomass; GRDB 24.2) and cassava (GRDB 22.2), respectively, while jatropha preferred bone meal (GRDB 17.2). However, leonardite/bone meal considerably reduced Cd uptake values in whole plant tissues of acacia and cassava (35 mg plant-1 and 119.1 mg plant-1, respectively), while bone meal/chicken manure greatly reduced Cd uptake values in jatropha (127.8 mg plant-1). Cassava is a Cd excluder; however, it may not be a useful bioenergy crop to cultivate in Cd soil because it displayed toxicity symptoms after harvesting. The best plant for phytomanagement in this study was jatropha, which demonstrated substantial growth biomass and Cd accumulation, followed by acacia.

In this article analyzes the development of trends of bioenergy crops market development in Ukraine and its current state are analysed. The possibility and feasibility of synergy of mutual development of bioenergy crops market and bio-oil market in Ukraine were noted. The necessity of state support and stimulation of bioenergy crops and different types of biofuels production in Ukraine was stated. A positive trend of growth of planted areas and production of rapeseed in Ukraine was revealed. During the study period (2013-2019) the production of rapeseed was increased by 1.4 times. The greatest energy potential for the production of bioethanol is in the sugar beet subcomplex of the agricultural sector. Over the past few years, the production of sugar beet was at its highest in 2014 (15.7 million tonnes), while the following years saw a decrease in cultivated areas of sugar beet and, consequently, a drop in its gross output - to 8.3 million tonnes in 2020. Significant resource potential for the production of bioethanol also have cereal crops (wheat, rye, barley, maize), the area under which during the last ten years remains relatively stable (14.4-15.3 million ha). Among grain crops the most effective raw material for the production of bioethanol is maize. A positive tendency of biennial growth of planted area under this crop is revealed. The space differentiation of resource base of bioenergy in Ukraine is prominent. The cluster analysis revealed three groups of areas based on the similarity of the energy resources for bioenergy purposes. Two clusters including Khmelnytskyi, Ternopil, Zhytomyr and Chernihiv, Vinnytsia, Cherkasy, Sumy, Kirovograd, Poltava and Kyiv regions should be considered as the most promising areas for concentration of capacities in biofuel production. It is noted that the trajectory of development bioenergetic sector of the country is always conditioned by compromise between compliance with optimal levels of its energy and food security.

Pot experiment was conducted during July-September 2006 to evaluate some organic amendments such as sesame (Sesamum indicum) biomass, buckwheat (Fagopyrum esculentum) biomass, neem (Azadirachta indica) leaves, chinaberry (Melia azedarch) leaves and chicken manure @ 1, 2 and 3 t ha-1 each against the rice root-knot nematode (Meloidogyne graminicola Golden & Birchfield) in direct seeded rice. The treatments were replicated five times in a randomized complete block design. The number of second stage juveniles (J2) of M. graminicola was significantly low in chicken manure @ 3 t ha-1. The root knot severity index was significantly low in sesame @ 3 t ha-1, chinaberry @ 3, 2 or 1 t ha-1, neem @ 3 t ha-1 and chicken manure @ 2 or 3 t ha-1 amended soil but root lesion severity index was lower only in chicken manure @ 2 t ha-1 treated plots. The fresh shoot weight and length were significantly high in chicken manure amendment @ 2 or 3 t ha-1 at 45th day after seeding. However, the fresh root weight, length, number of leaves and number of J2 recovered from the roots were non-significant.

Phytomanagement of trace element-contaminated soils combines sustainable soil remediation with the use of plant biomass for different applications. Consequently, phytostabilization using plant species useful for bioenergy production has recently received increasing attention. However, the water requirement of most of these species is a limitation for their use under Mediterranean climatic conditions. In this work, eight plant species growing naturally in mine soils contaminated by trace elements were evaluated for their use as bioenergy crops using thermochemical (combustion) and biochemical (anaerobic digestion) methods. The higher heating values of the biomass of the plants studied were all within a narrow range (16.03–18.75 MJ kg−1), while their biochemical methane potentials ranged from 86.0 to 227.4 mL CH4 (g VS)−1. The anaerobic degradation was not influenced by the presence of trace elements in the plants, but the mineral content (mainly Na) negatively affected the potential thermal energy released by combustion (HHV). The highest annual energy yields from biogas or combustion could be obtained by the cultivation of Phragmites australis and Arundo donax, followed by Piptatherum miliaceum. Both options can be considered to be suitable final destinations for the biomass obtained in the phytostabilization of trace element-contaminated soils and may contribute to the implementation of these remediation techniques in Mediterranean areas.

<p><em>Cauliflower is one of the vegetables for consumers. The demand for cauliflower was rising so it must be scaled up with fertilizer. The purpose of this study was to study the effect of chicken manure and NPK fertilizer on the growth and yield of cauliflower. The study was conducted in Sukasenang Village, Banyuresmi Sub-district, Garut Regency from July to August 2019. The study used a Randomized Block Design (RBD) in two factors each of the 3 rates with 2 replications. The first factor was the rates of chicken manure which consisted of 0, 10 and 20 tons ha<sup>-1</sup>; the second factor was NPK fertilizer which consists of 0, 100 and 200 kg ha<sup>-1</sup>. The parameter of this research was plant height, number of leaves, leaf area, weight and diameter crud. The results showed that there was no interaction between the chicken manure and NPK fertilizer. The treatment of 20 tons ha<sup>-1</sup> chicken manure affected the variable plant height, the number of leaves and leaf area. The rates of 200 kg ha<sup>-1</sup> NPK fertilizer had affected plant height, number of leaves, weight and diameter crud.</em></p>

The worldwide boom of biochar and pyrogenic carbonaceous material application as a potential soil additive has brought about not only agricultural benefits such as enhanced crop yield, nutrients supply (P), and soil organic carbon increase, but also, on the other hand, environmental risk of organic (polycyclic aromatic hydrocarbons (PAHs)) and potentially toxic element (PTE) penetration into arable soils. Therefore, our study assessed pyrogenic carbonaceous materials (PCM) produced from the P-rich feedstocks—chicken manure (CM) and bone meal (BM)—as promising and safe alternatives for inorganic P fertilizers. Pyrogenic materials produced in the process of slow pyrolysis at residence time 2 h, 400 and 500 °C, were characterized by determination of pH, electrical conductivity (EC), elemental analysis of total C, H, N, S scanning electron microscopy (SEM), total content of P, selected potentially toxic elements (PTEs), and available forms of PTEs and P by diethylenetriaminepentaacetic acid (DTPA) and calcium-acetate-lactate (CAL) extractions. CMPCM4, CMPCM5, BMPCM4, and BMPCM5 were characterized by determination of total 16 US-EPA (U.S. Environmental Protection Agency) PAHs by toluene extraction protocol and available concentrations by Tenax resin approach. Additionally, CMPCM4, CMPCM4, BMPCM4, and BMPCM5 were tested in earthworm avoidance test with Eisenia foetita and short-term rye-seedling germination test. Obtained results showed decreasing of total carbon in the order of BM > BMPCM4 > BMPCM5 and increasing in the order of CM < CMPCM4 < CMPCM5. Total phosphorus content increased from 56.8 ± 1.7 g kg−1 (BM) to 85.2 ± 4.2 g kg−1 (BMPCM4) to 110.5 ± 7.0 g kg−1 (BMPCM5). In the case of chicken manure-derived pyrogenic materials, total phosphorus content increased in the order of CM (22.9 ± 2.0 g kg−1) < CMPCM4 (37.0 ± 4.5 g kg−1) < CMPCM5 (40.0 ± 3.4 g kg−1). Availability of selected PTEs and P decreased in pyrogenic materials compared to feedstock. Total concentration of ∑16-US-EPA PAHs in BMPCM4 and BMPCM5 was 3.92 mg kg−1; CMPCM4, 7.33 mg kg−1; and CMPCM, 6.69 mg kg−1. The Tenax-available ∑16-PAHs showed concentrations of 0.53 mg kg−1 for BMPCM4, 0.26 mg kg−1 for BMPCM5, 1.13 mg kg−1 for CMPCM4, and 0.35 mg kg−1 for CMPCM5. Total P concentrations determined in rye aboveground tissues showed the highest accumulation ability in the case of CMPCM5 compared to other samples. Pyrogenic carbonaceous materials produced from chicken manure and bone meal at 400 and 500 °C have the potential to be P slow release fertilizers and may be ecologically safe.
