Verbreitungsmuster von Unkrautarten in Maiskulturen in Mardan, Pakistan by Zeeshan Ahmad, Shujaul Mulk Khan Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Unkraut sind unerwünschte Pflanzenarten, die in Kulturpflanzen wachsen. Wie andere Kulturpflanzen auch, ist Mais mit dem Problem der Konkurrenz durch Unkraut konfrontiert. In kleineren landwirtschaftlichen Betrieben wurden aufgrund von Unkraut Verluste von bis zu 70 % der Maisernte gemeldet. Die Zusammensetzung und Häufigkeit von Unkraut wird durch eine Reihe von Umweltvariablen sowie durch landwirtschaftliche Praktiken in einem Ökosystem beeinflusst. Die vorliegende Studie wurde konzipiert, um den Einfluss von Umweltvariablen auf die Zusammensetzung, Häufigkeit, Verbreitung und Bildung verschiedener Unkrautgemeinschaften im Distrikt Mardan in Pakistan zu untersuchen. Für jedes Feld wurden phytosoziologische Merkmale wie Dichte, Häufigkeit, relative Dichte, relative Häufigkeit und Importanzwerte gemessen. Die Daten zur An- und Abwesenheit von 29 Arten und 65 Feldern wurden mit Hilfe von Cluster- und Zwei-Wege-Clusteranalysen mit PC-ORD Version 5 analysiert, was zu vier Hauptunkrautgemeinschaften führte. Die CANOCO-Software Version 4.5 wurde verwendet, um die Umweltgradienten von Unkräutern durch kanonische Korrespondenzanalysen (CCA) zu bewerten. Die Ergebnisse zeigten, dass unter allen Umweltvariablen die stärksten Variablen CaCO3, hohe Phosphorkonzentration und höhere elektrische Leitfähigkeit waren.

  1. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  2. Leaving positive feedback because 1) item was packed well & arrived as described 2) seller did give partial refund when subsequent price dropped below org purchase price. 3) communication was quick However, there was a downside to this transaction -item listed as in-stock but ended up waiting nearly a month for them to get it from their distributer then ship it to me (bought June 29th, arrived around July 21). Auction said 12-15 days. Better clarity would have prevented lot of frustration

  3. The seller was very responsive and answered me on a timely matter. The product itself came in its packaging and was new, not used at all. The packaging was not beat up or anything, safely delivered to my mailbox. No mix ups and zero stress with delivery. The price for the product is completely understandable for the product. I really appreciate the seller and I am very happy to have purchased through this seller. Completely trustable!
