Rpartition des espces de mauvaises herbes dans les cultures de mas Mardan, au Pakistan by Zeeshan Ahmad, Shujaul Mulk Khan Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Les mauvaises herbes sont des espèces végétales indésirables qui poussent dans les cultures domestiquées. Comme d'autres cultures, le maïs est également confronté au problème de la concurrence avec les mauvaises herbes. Des pertes de rendement pouvant atteindre 70 % ont été signalées dans les petites exploitations agricoles en raison des mauvaises herbes. La composition et l'abondance des mauvaises herbes sont influencées par un certain nombre de variables environnementales ainsi que par les pratiques agricoles dans un écosystème. La présente étude a été conçue pour mesurer l'effet des variables environnementales sur la composition, l'abondance, le schéma de répartition et la formation de diverses communautés de mauvaises herbes dans le district de Mardan, au Pakistan. Des attributs phytosociologiques tels que la densité, la fréquence, la densité relative, la fréquence relative et les valeurs d'importance ont été mesurés pour chaque champ. Les données de présence ou d'absence de 29 espèces et 65 champs ont été analysées à l'aide d'analyses par grappes et par grappes bidirectionnelles via PC-ORD version 5, ce qui a permis d'identifier quatre communautés principales de mauvaises herbes. Le logiciel CANOCO version 4.5 a été utilisé pour évaluer les gradients environnementaux des mauvaises herbes à l'aide d'analyses de correspondance canonique (CCA).

  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!
