Magnetic field may be applied as a physical factor to improve germination capacity as well as growth and development of plants. In order to investigate the influence of stimulation with magnetic field and fertilization on the yield and quality of sugar beet roots, a field experiment was carried out in 2015 and it was designed to examine three cultivars of sugar beets, two variants of magnetic stimulation applied to seeds: stimulation in the magnetic field of 40 mT, and control conditions (no stimulation), as well as two variants of mineral fertilization: optimal, based on the contents of nutrients in soil, and control conditions (no fertilization). Observation of the plants’ growth and development was conducted during the vegetation period. The examined values included yield of roots and leaves, as well as contents of heavy metals, macro- and micro-elements and sugar. The observations carried out during the experiment and following harvest showed that the applied variable factors used in the experiment, i.e. the pre-sowing stimulation with magnetic field as well as properly designed fertilization, positively affect the parameters of the plants germination, growth and development as well as the contents of sugar in the examined sugar beet roots.

The aim of the study conducted in the years 2014-2016 was to determine the effects of different irrigation systems and doses of different organic fertilizers on the yield of crisphead lettuce. The experiments were conducted in a certified organic field of the Research Institute of Horticulture in Skierniewice. The study compared micro-sprinkler irrigation, drip irrigation and the control combination (without irrigation). The fertilization combinations involved the use of compost at 30 t/ha, Ekofert L in a dose corresponding to 50 and 100 kg N/ha, Fertilan L in a dose corresponding to 50 and 100 kg N/ha, and the control (no fertilizer). It was found that the use of irrigation in the first and third year of the study did not produce positive results, which was due to sufficient rainfall that fully satisfied the water requirements of lettuce plants. However, with a total rainfall not exceeding 80 mm (in 2015), the use of the irrigation systems had a significant impact on yield. Compared with the control, the irrigation with micro-sprinklers in 2015 increased the yield of lettuce by 35%, and in the case of drip irrigation by 40%. The response of lettuce plants to the applied organic fertilization varied in the individual years of the study; however, of all the tested fertilization treatments, the use of compost at 30 t/ha produced the best yield-enhancing effect. Fertilization with the lucerne-based fertilizers resulted in an increase in yield, in relation to the control combination, in only one year of the study (2015). The results showed that the organic fertilizers Ekofert L and Fertilan L were slow-acting fertilizers because their impact on the yield of lettuce, a plant with a short vegetative period, was relatively small. These fertilizers are more effective in the cultivation of species that have a long period of vegetative growth.

The object of our study is soil fertilized with a variety of compost produced from unsorted municipal waste maturing in heaps for different lengths of time, and with green waste compost. Municipal waste composts were applied at rates of 10 and 30 g·kg-1 soil, whereas green waste compost was introduced to soil as 10 g·kg-1 soil. Processes that take place during compost maturation have resulted in an increased concentration f polycyclic aromatic hydrocarbons. More PAHs were determined in municipal waste composts than in green waste compost. Fertilization of soil with municipal waste composts increased the content of PAHs in soil, but in most cases the natural concentration of these compounds was not exceeded. However, the total PAHs more than 200 μg·kg-1 d.m. soil, which is above the natural content, were observed in the objects where the highest rates of one- and three-month-old composts were applied. In the objects fertilized with green waste compost, total PAHs (as well as the levels of particular compounds) were close to the values recorded for the control object.

The experiment was based on two factors: 4-levels of fertilization with ash from biomass - 0; I - 4.28; II - 8.57; III - 12.85 tha-1 and 2-levels of fertilization with sewage sludge: 0; 1–30.3 tha-1. The experimental plant was Jerusalem artichoke (Helianthus tuberosus L.), Gigant cultivar. The contents of nitrogen tended to increase in response to fertilization with sewage sludge and to decrease with a growing dosage of fertilization with biomass ash. The use of municipal sewage sludge as a fertilizer did not produce visible changes in the contents of six macronutrients (carbon, phosphorus, potassium, sulfir, calcium and magnesium) in overground part of Jerusalem artichoke. The use of ash at the dose of 12.8 tha-1 resulted in an increase in potassium contents in the plants, to the level of 5.63 g Kkg-1 during the first year of trials and the trend was continued in the second year. Biomass chemical stability in 2-year experiment was noted except the content of nitrogen, cadmium and lead which were increasing while the level of sewage sludge increased. The content of zinc, copper, lead and cadmium in overground part of Jerusalem artichoke did not exceed the threshold values defined for wood pellets and briquettes by the standards set forth by DIN 51731 1996–10.

The paper summarises the results of the comprehensive scientific research carried out in the form of a two-factor stationary experiment (5 primary tillage systems × 3 fertilization systems) with rotation (2016–2020) of cereal crops (winter wheat – grain maize – spring barley – soybean) in grey forest fine sand and light loam soil. The effectiveness of the tested agricultural production method has been proven by the amplitudes of the actual cropping capacities: winter wheat – 2.80–5.00 t∙ha–1; grain maize – 4.16–8.89 t∙ha–1; spring barley – 1.78–4.45 t∙ha–1; soybean – 1.02–3.17 t∙ha–1. The rehabilitation of the physical, agrochemical and biological status of the edatope and the consolidation of the physiological processes in the grain cenoses achieved by the systemic approach to the soil tillage and fertilisation have provided for an increase in the natural biological potential of the plough land by a factor of 1.3–1.8 (from 2.96 to 5.21 t∙ha–1 of grain units, units for the equivalent measuring of different plant cultivation products). Factographic justification has been provided for the environmental, technological and technical-and-economic feasibility of implementing agronomic technologies based on the adaptive combination of mouldboard and non-mouldboard tillage (to a depth of 6–45 cm) and organic and mineral fertilization system (6.5–7.0 t∙ha–1 of plant cultivation by-products + N70P58K68). In this case, the effective fertility of an area unit in crop rotation reaches 5.72 t∙ha–1 in grain units, the production cost of raised grain – 117 €∙t–1, the earning capacity – 788 € (ha∙year) –1, the level of plant cultivation profitability – 139%. In the comparable alternatives of the system-based soil tillage (every-year ploughing, subsurface blade tillage and especially tillage with disk implements), the indices estimated above are significantly lower.

Pruning and fertilization practices plays an important role in coffee plantation, used to maintain soil quality and coffee productivity. However, the impact of pruning and fertilization practices on soil microbial activity under coffee-based agroforestry are poorly understood. The aimed of this study was to analyze the response of soil microbial properties (i.e., soil microbial biomass C (SMBC) and soil respiration rates (SR)) to pruning and fertilization management in coffee-based agroforestry in UB (Universitas Brawijaya) Forest. A split-plot design with eight treatments and three replications were used in this experiment. The main-plot factor consisted of two types of pruning (Pruning and Bending), and the sub-plot factor consisted of four types of fertilization (i.e., no fertilizer (NF), 100% chicken manure (MN), 50% chicken manure + 50% NPK-inorganic (MN+NPK), and 100% NPK-inorganic (NPK)). The result showed that there was a significantly different (p<0.05) in the soil microbial biomass C and soil respiration after the application of fertilizer. The addition of chicken manure (MN and MN+NPK treatment) could enhance the soil microbial biomass and soil respiration, compared to the NF treatment under different pruning practices. The level of soil pH in MN were highest and significantly different with NPK treatment, showed that the application of chicken manure had a potential to neutralize the soil acidity. Metabolic quotient (qCO2) showed highest in the NF treatment as compared to the other treatments. The soil respiration had positive correlation (p<0.05) with SMBC, while SMBC had negative correlation (p<0.01) with qCO2.

Most of the developing countries economy largely depends on the agriculture. More than half of the population rely on agriculture related activities for their survival. In spite of dependency on agriculture, the technological development of agricultural work in developing country is not comparable to the countries like Australia or Israel. The main reason behind the lack of development is the small size of farms. Such farmers cannot afford expensive technology available in the market due to limited profit margins. The report describes an autonomous fertilization system that takes care of the fertilization requirements of the small scale farms at affordable rates. The system is divided in two parts namely User Interface and Control System. The user interface is designed using the state of the art Raspberry Pi board and a touch screen LCD. The control system is developed using the Arduino platform and can control five fertilizers at a time. The output of the system is the mix of the fertilizer, which is forced into the drip irrigation system of the farm. The system has built in data for the fertilization requirement for important crops and vegetation. The system also facilitates the customize fertilization requirements to be added in the system as per the user requirements.

The field experiment was carried out in 2004-2006 in Chlebówko localized 20 km from Stargard Szczeciński and 5 km north-east from Stara Dąbrowa commune - 53°27’N and 15°10’E. The area is elevated 62-72 m above mean se level (ASL). The influence of irrigation, tillage system, and NPK mineral nutrition on weed infestation of faba bean variety ‘Titus’ with determined development rate, was evaluated. The weed infestation degree in the faba bean plantation depended on moisture conditions, fertilization rates, and tillage system. Irrigation increased the number, fresh weight, and dry matter of weeds, respectively by 92%, 130%, and 138%. Likewise, increasing nutrition elevated values of these parameters by 46%, 80%, and 95%. The tillage simplifications enhanced the weed population, particularly on irrigated and fertilized objects. Irrigation, mineral nutrition, and simplified tillage caused compensation of spring, winter and perennial weed species on plantation of faba bean ‘Titus’. Chenopodium album, Stellaria media, and Polygonum convolvulus predominated on studied plots.

Up till now, no critical contents have been elaborated which permit to evaluate the correct microelement nutrition on the basis of chrysanthemum stock plant leaves analysis. Experiments were carried out to determine the content of iron, zinc and copper in the leaves of chrysanthemum motherplants by studying 16 cultivars in 2000 and 13 cultivars in 2001. Analyses were carried out at 4 terms (from: February to May). The values characterizing the content of the particular components in the leaves of each cultivar of chrysanthemum were statistically elaborated. Standard deviation for the cultivars and variation coefficient for the whole population in the given year were calculated. The usability of guide values utilized for traditional methods of chrysanthemum growing in diagnostics of plant nutrition were critically evaluated. New standard ranges of the content of iron, zinc and copper in chrysanthemum motherplant leaves were elaborated.
