The use of cannabis for medicinal purposes dates back well before the era of modern medicine, but in recent years research into the use of medical cannabis in the medical and pharmaceutical sciences has grown significantly. In European countries, most cannabis plants have been and still are grown for industrial purposes. For this reason, hemp cultivation technology is relatively well researched, while little is known about the key factors affecting cannabis cultivation for medical purposes. The active substances of cannabis plant targeted by this review are called phytocannabinoids. The biosynthesis of phytocannabinoids is relatively well understood,...

Phosphorus (P) deficiency may trigger rhizodeposition, including protons and organic compounds, with possible effects on metal solubility and speciation. To explore the relevance of this process, we investigated biogeochemical changes in the rhizosphere of P-deficient canola (Brassica napus L.) and corn (Zea mays L.) cultivars grown in a pot experiment on calcareous soil. Depletion of total soluble (0.005 mol/L Ca(NO3)2-extractable) P in the rhizosphere varied with crop species and cultivar but was generally strong and negatively correlated with dissolved organic carbon (DOC) in canola (R2 = 0.868) and corn (R2 = 0.844) rhizospheres, indicating rhizodeposition...

The effect of agrotechnical elements (crop rotation, fertilisation, irrigation) on maize yield and various chemical characteristics of the soil (pHH2O, pHKCl, hydrolytic acidity (y1)) were examined in a long-term experiment (established in 1983) on calcareous Chernozem in the Hajdúság region of Hungary. The yield obtained in 2019 showed the favourable water supply of the crop year and outstanding nutrient utilisation of maize. In the control (non-fertilised) treatments, maize yield was 8 t/ha in monoculture, 11 t/ha in biculture and 12 t/ha in triculture, while the highest yield obtained with the optimum fertiliser treatment increased to 13, 13.5 and...

Intercropping system plays a crucial role in improving crop yield, nitrogen utilisation efficiency (NUE) and economic benefit. The difference in crop yield and interspecific relationship under different bandwidth and row ratio allocation patterns are still unclear. A field experiment was carried out to explore change regularities between crop yield and interspecific relationships under maize soybean intercropping with different bandwidths and row ratios. The results showed that the yield of intercropped crops was lower than that of the sole crop. The nitrogen accumulation (NA), NUE and nitrogen competition ratio was the highest under the intercropping...

Enhanced seeds, e.g. dressed, encrusted or pelleted seeds, are often sown in agricultural practice. These treatments play a different role depending on the type and chemical composition of the preparation. The aim of the experiment was to compare the effectiveness of three coatings (B - chitosan, C - chitosan + alginate/jojoba oil/E and D - chitosan + alginate/PEG) applied to soybean seeds in comparison to control (A). The study was carried out in three cultivars: Annushka, Mavka and Smuglyanka. The coatings did not differentiate seed yield in 2018 due to favourable weather conditions. The use of coating D in the following years increased seed yield...

Immobilisation of lead (Pb) and toxic elements in contaminated soils is of importance due to their persistence in the environment. Herein, we investigated the effects of sugarcane filter cake biochar (SFCB) and sugarcane bagasse ash (SBA) on the extractability of Pb and some toxic and potentially toxic elements (As, Cd, Cu, and Zn) in polluted mine soil samples from Lower Klity Creek, Thailand. The soil was equilibrated with the SFCB and SBA at the respective rates of 0, 1, and 5% (w/w) for 120 days at field capacity. The results revealed that both SFCB and SBA materials significantly (P < 0.05) decreased Pb extractability...

The paper examines the effect of the long-term (10 years) low-intensity sprinkler irrigation on the properties of leached chernozem soils covered with Bromopsis inermis Leyss. (BIL) stands in the Southern Cis-Ural forest-steppe. The study analysed changes in the soil's agrophysical and chemical properties. As a result of long-term irrigation, the humus horizon (A + AB) thickness increased by 16 ± 3 cm; the organic carbon (Corg) content and nutrients decreased in this rooting zone, in particular, Corg by 0.3%, available phosphorus by 24.8 mg/kg, exchangeable potassium by 18.4 mg/kg and the stock of Corg by 16 t/ha. The particle size distribution...
