The critical period of weed interference in groundnut was investigated in 2018 and 2019 early cropping seasons at the Federal University of Agriculture, Abeokuta, Ogun State, Nigeria. The experiment consisted of ten treatments arranged in a randomized complete block design and replicated three times. Treatments includes keeping plots weed free initially for 3, 6, 9, 12, 15 weeks after planting (WAP) and keeping plots weed infested initially for 3, 6, 9, 12, 15 WAP. Data collected on weed cover score, weed dry matter production, crop vigour score, canopy spread, pod yield and numbers were subjected to analysis of variance and treatment means were separated using least significant difference at P ≤0.05. The results showed that total weed dry matter production increased with weed infestation period and decreased with weed free period. Also, there was significant increase in pod yield and count when plots were kept weed free for 6 WAP and more. Our findings showed that, the highest percent weed accumulation, weed removal, pod yield loss and pod yield gain all occured between 3 and 6 WAP. Therefore, the critical period of weed interference in groundnut is between 3 and 6 WAP. Also, there was 83.4% pod yield loss in groundnut when weed was allowed to compete freely with the crop throught crop life cycle.

Neighboring villages are Žirany, Jelenec, Pohranice, Čeľadice and Hosťová. The area is a part of the lucerne – barley – wheat region. Cereals such as barley, wheat and fodder predominate in crop production. The village is an important wine region. The total area of the agricultural land fund in the During 2014, water temperature of the Bocegaj brook and the Kolíňany pond and its impact on fish life were monitored. Water sampling was carried out at regular monthly intervals, in the period from January to October, from six sampling points. The four sampling points were located directly on the water surface of the pond, the last place being the outlet from the pond. In this time horizon, all four seasons alternated, which was also reflected in the change of the water temperatures. The lowest average value of water temperature was recorded in January (0.5 °C) and the highest in June (19.23 °C). The maximum values of water temperature depending on the sampling point during the monitored period were found in the open water area of the pond.

The aim of the work was to analyse the impact of different intensities of grassland exploitation on the productive capacity in the context of declining livestock numbers and the need for temporary or permanent extensification. The research was carried out in 2017–2020 in the locality of Žirany in the Nitra district, located in the temperate zone at the boundary between the continental and Atlantic-continental regions. Average annual temperatures are around 9 °C. The original semi-natural vegetation has been used for sheep grazing for many years. There were 8 experimental variants of use/cutting with different intensity of exploitation: var. 1 – abandoned unused, var. 2 – 3 × per year, var. 3 – 2 × per year, var. 4 – 1 × per year, var. 5 – 4 × – 3 × – 2 × – 2 × – 1 × per year, var. 6 – 1 × – 2 × – 3 × – 4 × per year, var. 7 – 3 × – 1 × – 1 × – 3 × and var. 8 – 2 × – 1 × – 1 × – 1 × – 2 × . By comparing the sum of yields for the entire 4-year annual cycle, we concluded that, with the exception of the 1 × annually mowed variant, all the others differentiated themselves from the abandoned stand by their increased production capacity. We also observed differentiation between fertilized and exploited variants into groups. The stand mowed 3 times annually (variant 2, 29.07 t/ha) was shown to be the most productive. The second group consisted of variants with production lower in the sum of 4 years by about 5 t/ha (3, 5, and 6). The same level of lower yield was then found on stands with temporarily reduced intensity of use (variants 7 and 8). In the effectiveness of applied nutrients on production growth, it was found that as the number of applications increased, nutrient use also increased. The average of the years in the overall assessment of the 4-year cycle showed the dynamics from the individual years and also confirmed the tendency of the highest nutrient use at a stable 3-cut use.

The goal of the study was to evaluate the effect of dietary inclusion of common mugwort ( Artemisia vulgaris ) herb on selected growth and health traits of young dwarf rabbits. The mugwort species represent regular botanical species with proven favourable effects on health state of many animal species. However, a dietary effect of Artemisia vulgaris (AV) on health of dwarf rabbit genepool has not been studied yet. The study was performed on a total of 12 kits of the Dwarf Lop breed. These kits were divided into 2 groups (control, C; experimental, E). From the age of 21 days up to the age of 112 days the kits in the experimental group received a complete diet specifically designed for the dwarf rabbits with 10% supplementation of the AV meal. There was found no significant adverse effect on live weight and average daily weight gain in rabbits of the E group. Concerning the anticoccidial effect, the 112-day-old rabbits fed the E diet showed a significantly lower ( P <0.05) number of excreted oocysts (1766 OPG) as compared to those in the C group (6845 OPG). Based on the results of the present study, there can be suggested that 10% dietary inclusion of the AV meal represents a safe share and it showed a positive effect on the excreted coccidiosis count in dwarf rabbits. However, it would be suitable to perform further studies, when the optimization of a mugwort dietary level during specific life periods of dwarf kits and the selection of other Artemisia botanical species will take a place. In addition, monitoring of more growth traits and biological effects of particular substances contained in Artemisia sp. would be studied on dwarf pet rabbits as wel.

This paper aims to study the growth and development of garden pea plants when liming the soil, applying mineral fertilizers, pre-sowing seed treatment with inoculants, micronutrients and foliar nutrition. Plants survival was higher in the trial variant when applying lime (1.0 norm of lime per ha), mineral fertilizers, pre-sowing seed treatment with Rhizobophyte and microfertilizer Wuxal Extra CoMo, foliar nutrition with microfertilizers Wuxal Microplant at the microstage ВВСН 12–13 and Wuxal Calcium, Boron at the microstage ВВСН 51–59 – 92.0% and 92.1% in Skinado and Somerwood garden pea varieties. In the same variant, maximum values of the use of photosynthetic active radiation (PAR) were observed in Skinado variety – 1.38 and Somerwood variety – 1.89%. This was 0.47 and 0.57% higher compared to the control. The longest period of symbiosis, both general and active, was 35.3 and 37.1, 25.4 and 26.7 days. This was 2.2, 4.6, and 1.6 days more compared to the control where liming was applied. The highest rates of symbiotic and active potentials were observed in Skinado and Somerwood varieties and amounted to 14.0 and 15.4, 7.8 and 8.6 thousand kg per day/ha, and the amount of symbiotically fixed nitrogen (SNF) was 148.2 kg/ha in Skinado and 172 kg/ha in Somerwood variety. Pea yield was 9.36 t/ha in Skinado and 11.09 t/ha in Somerwood varieties. This was 2.15 and 2.14 t/ha more compared to the control. Green pea output was 46.4% in Skinado and 50.3% in Somerwood varieties. This was higher compared to the control by 4.4 and 3.0%, respectively.

Fall Armyworm ( Spodoptera frugiperda ) is one of the new pests from the Lepidoptera class, which causes huge losses for farmers, especially in corn plantations. The purpose of this study was to determine the effectiveness of cigarette butt waste and soursop leaf ( Annona muricata L.) extracts as biopesticides against fall armyworms by observing the mortality and analyzing their LC 50 . Extraction of cigarette butts waste and soursop leaves by ethanol 96% as solvent was carried out using Microwave-Assisted Extraction (MAE) method. As the comparison, the maceration and soxhletation extraction of soursop leaves were conducted and analyzed their chemical content by using LC-MS/MS instrument. The insecticide study used a completely randomized design (CRD) method to treat larvae instar III with cigarette butt waste and soursop leaf extracts with various concentrations in three repetitions. Data analysis was performed using probit analysis. The results showed that soursop leaf extract contained four major acetogenin compounds, namely muricatalicin, annohexocin, robustocin, and epoxymurin, with a total percentage of 31.41% by using MAE method, which is higher than the acetogenin content of the maceration and soxhletation extracts (23.73% and 17.78%, respectively). Both cigarette butt waste and soursop leaf extracts were effective as biopesticides with an LC 50 value of 4.900% and 4.114%, respectively, in 12 hours of observation.

The purpose of this study was to determine the effectiveness of cigarette butt waste and soursop leaf ( Annona muricata L.) extracts as biopesticides against fall armyworms by observing the mortality and analyzing their LC 50 . Extraction of cigarette butts waste and soursop leaves by ethanol 96% as solvent was carried out using Microwave-Assisted Extraction (MAE) method. As the comparison, the maceration and soxhletation extraction of soursop leaves were conducted and analyzed their chemical content by using LC-MS/MS instrument. The insecticide study used a completely randomized design (CRD) method to treat larvae instar III with cigarette butt waste and soursop leaf extracts with various concentrations in three repetitions. Data analysis was performed using probit analysis. The results showed that soursop leaf extract contained four major acetogenin compounds, namely muricatalicin, annohexocin, robustocin, and epoxymurin, with a total percentage of 31.41% by using MAE method, which is higher than the acetogenin content of the maceration and soxhletation extracts (23.73% and 17.78%, respectively). Both cigarette butt waste and soursop leaf extracts were effective as biopesticides with an LC 50 value of 4.900% and 4.114%, respectively, in 12 hours of observation.","PeriodicalId":7312,"journal":{"name":"Acta Fytotechnica et Zootechnica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46613109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
