Nutrient management is vital for maximizing forage crop yield and economic viability; however, improper application can result in decreased yield and quality. Therefore, two seasonal experiments were conducted during the winter seasons of 2022-2023 and 2023-2024 to examine the impact of varying nitrogen, phosphorus and potassium (NPK) levels, along with the foliar application of zinc, on the forage yield and nutrient content of Egyptian clover or berseem (Trifolium alexandrinum L.) grown in calcareous soil conditions (>36% CaCO3). The experiment consisted of eight treatments, including two NPK levels (50% and 100% of the recommended dose) and two forms of Zn (Zn NPs and Zn Edta at 0.2 and 0.5% as foliar sprays), compared with the control (without treatment). Results showed that NPK full dose (100%) or in combination with Zn NPs significantly improved fresh and dry weight by an average of 67%, and 80%, respectively, across all cuts. Whereas, the highest protein percentage in berseem forage occurred with 50% NPK and foliar Zn NPs. Protein yield per unit area was highest with 100% NPK and foliar Zn NPs in the second and third cuts. Furthermore, Zn NPs boosted manganese (Mn) levels in the 2nd cut but decreased them in the 3rd cut. Iron (Fe) and Mn were mostly in normal ranges, but zinc was often below normal levels. Overall, Zn NPs increased forage yields. The results of translocation factor (TF) for micronutrients from the soil to berseem plants showed that TF values were > 1 for all micronutrients except for Cu in several instances in the 2nd cut in such calcareous soil. Furthermore, micronutrient translocations were arranged in the following order Cu < Zn

Our study suggested that there is a beneficial role of correcting Zn deficiency under calcareous soil conditions which is reflected on berseem yield and quality and nutrient status. Thus, using ZnO NPs along with the full recommended dose of NPK is a suitable approach to enhance berseem crop yield and quality in calcareous soil.","PeriodicalId":507826,"journal":{"name":"Journal of Soil, Plant and Environment","volume":"4 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140734996","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}
Plastic is considered an emerging agroecological pollutant while biological invasion has also become a global environmental issue. Therefore, the contamination of microplastics and the occurrence of Solidago canadensis L. invasion in the agroecosystem may be a severe hazard to soil and plant functioning, reducing yield and perhaps indirectly harming human health. Microplastic contamination adversely affects the soil ecosystems in terms of soil carbon pools and their turnover. Invasive plants compete with agronomic crops, have allelopathic effects by secreting allelochemicals, and have detrimental effects on the productivity of the crops. However, their interaction had significant negative effects on the soil as well as the crop's physiological and biochemical properties. Thus, the interactive response created a big gap in how they raise concerns about crop potential yield and entering into the food web that ultimately affects human health.
塑料被认为是一种新兴的农业生态污染物，而生物入侵也已成为一个全球环境问题。因此，农业生态系统中的微塑料污染和 Solidago canadensis L. 的入侵可能会严重危害土壤和植物功能，降低产量，并可能间接危害人类健康。微塑料污染会对土壤生态系统的土壤碳库及其周转产生不利影响。入侵植物与农作物竞争，通过分泌等位化学物质产生等位病理效应，并对农作物的产量产生不利影响。然而，它们之间的相互作用对土壤以及作物的生理生化特性都有显著的负面影响。因此，这种交互作用造成了一个很大的缺口，即它们如何引起人们对作物潜在产量的关注，以及如何进入食物网，最终影响人类健康。

Biochar and the use of legumes in cropping systems are considered sustainable approaches to boost crop yield and preserve soil fertility. In the current study, the effects of leftover biochar and previously planted legumes on wheat yield and soil N status were examined at various nitrogen (N) levels. The experiment included testing two levels of previously applied biochar (0 and 50 tons ha-1), three legumes under four levels of N (0, 60, 90, and 120 kg ha-1), cowpea (Vigna unguiculata) for fodder, Sesbenia (Sesbenia grandaflora) for green manuring, and mung bean (Vigna radiata) for grain. Results showed that biochar application enhanced wheat tiller m-2, spikes m-2, grains per spike, thousand grain weight, grain yield, biological yield, and soil total N status by 3%, 6.5%, 3.7%, 1.8%, 7.8%, 9.5%, and 11%, respectively. Moreover, applying nitrogen at a rate of 90 kg ha-1 increased the amount of wheat spike m-2 by 20%, grain spike-1 by 10%, grain yield by 70%, biological yield by 48%, harvest index by 27%, and the N content of the grain, straw, and soil by 13%, 14%, and 36% respectively. Meanwhile, 1000 grain weight resulted higher by 6.17%. Legumes that had been previously seeded outperformed fallow and increased spikes m-2, grain yield, biological yield, grain N content, and soil total N content by 8.2%, 11%, 6.78%, 25%, and 42%, respectively. It is determined that applying biochar to the summer gap left by legumes can increase soil fertility and wheat output.
