Inconsistent results were obtained on the yield of rice genotypes established along the soil toposequence thus the need to validate these under controlled environment with rice genotypes. This investigation hypothesised there could be variation in the growth and yield of rice genotypes in different soil types under soil water deficit. A pot experiment was established in an open screen house, Ibadan. The treatment consisted of rice varieties (IR 64, IR 77298-14-1-2-B-10, NERICA 4 and WAB 56-104), soil ecologies [hydromorphic (H), lowland (L) and upland soils (U)] and soil moisture regime (Control and water deficit stress), in completely randomised design...

The field trial evaluating the effect of biochar on physical and hydro-physical properties of a Dystric Cambisol was carried out at the Research Grassland Station Vatín. The observed variants of the biochar experiment were as follows: 1) the control without biochar, 2) the biochar rate of 15 t/ha applied to the topsoil, 3) the biochar rate of 30 t/ha applied to the topsoil and 4) the biochar rate of 45 t/ha applied to the topsoil. It was found out that even the highest rate of biochar 45 t/ha did not affect saturated hydraulic conductivity of the topsoil at the depth of 0.05-0.20 m. When monitoring bulk density, it was confirmed that the biochar rate...
Quantification of 'Candidatus Phytoplasma prunorum' in apricot trees exhibiting uneven European stone fruit yellows symptoms

Acta Univ. Agric. Silvic. Mendelianae Brun. 2022, 70(1), 31-36 | DOI: 10.11118/actaun.2022.003
This study focused on quantification of 'Candidatus Phytoplasma prunorum' in apricot trees exhibiting uneven symptoms of European stone fruit yellows. For the research, 17 trees showing early leaf bud break in one part of the crown were selected in winter season, and 13 trees showing leafroll in older part of the shoots and no symptoms in younger part of the same shoots were selected in summer season. Absolute quantification of phytoplasmas was performed by real-time PCR in samples collected from asymptomatic and symptomatic parts. The results showed, that phytoplasma could not be always detected in asymptomatic parts, where 2 out of 17 samples from...
Influence of Different Weed Control Methods on Weed Density and Relative Importance Value of Weeds in Mango Ginger (Curcuma amada Roxb.)

Field trials were conducted in the early cropping seasons of 2016 and 2017 at the Teaching and Research Farm of the Federal University of Agriculture Abeokuta (07° 20ʹN , 3° 23ʹE 159 m above sea level) in a derive savannah agro ecology region of South-western Nigeria to evaluate the effect of weed control methods on weed density and weed species composition in mango ginger. Ten weed control methods were evaluated and laid out in a randomized complete block design with three replications. Data collected on weed density were subjected to analysis of variance (ANOVA) and treatment means separated using 5% least significant difference (LSD...
Effect of Different Storage Methods on the Microbiological Quality of the Insect Dry Powder Made from Mealworm (Tenebrio molitor, L.)

Acta Univ. Agric. Silvic. Mendelianae Brun. 2022, 70(1), 47-50 | DOI: 10.11118/actaun.2022.005
Entomophagy as an alternative way of eating in the Czech Republic is gaining more and more supporters. For this reason, we have focused on the microbial quality of the insect dry powder made from Tenebrio molitor during storage. In the samples were determined the major groups of microorganisms by standard procedures. It is the total number of microorganisms, aerobic microorganisms thermoresistant, E. coli and other coliform bacteria, micromycetes and bacteria of the genus Enterococcus. The highest increase of total microorganisms occurred after five months storage in the sample stored in a paper bag and cold, where their number reached a value of 2.870...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2022, 70(1), 51-58 | DOI: 10.11118/actaun.2022.006
This study was motivated by the report of a survey of herbal remedies used by Fulani herdsmen in the management of cow diarrhoea in Plateau State, Nigeria. The report identified F. platyphylla stem bark amongst major herbs. Activity of aqueous stem extract of F. platyphylla against diarrhoea caused by physiological changes and by pathological infections was herein determined. Thirty albino rats were fasted for 18 hours. They were grouped into six and induced with diarrhoea using castor oil. The first two groups received distilled water (1 ml) and loperamide (5 mg/kg), while other groups were administered plant extract 50, 100, 200 and 400 mg/kg body...
