Weeds Biomass as Affected by Tillage Practices and Cropping Systems under a Semiarid Environment
Tillage practice has a significant role on weeds eradication and soil water conservation in crop production. Under semiarid agriculture, the monsoon rains (65%) are major source of water in Potohar, Pakistan, which can effectively be used mostly for winter crops production. To evaluate the impact of different tillage system for prevailing cropping systems and their weeds biomass under semiarid conditions, field experiment was conducted at the Arid University Research Farm Koont Rawalpindi (Pakistan) during crop growth seasons 2013-14 and 2014-15. Tillage systems as treatments were (a) three cultivations with a cultivator, as control treatment, (b) mold-board with two cultivations, (c) chisel-plough with two cultivations and (d) minimum tillage (only tillage performed at sowing time) with glyphosate. Sowing was made using drill for all cropping systems i.e. a, b, and d except c which was planted on bed (made by bed planter). In addition to ploughing treatments, different cropping systems (a) wheat fallow (b) wheat and brassica fallow, (c) wheat and chickpea fallow and (d) wheat cluster bean (green manure crop) were also used for minimum two years rotations. On average in both study years, interactive effect of treatments (mold board with 2 cultivations) for the rotation wheat and brassica fallow showed a reduction in weeds dry biomass of Anagallis arvensis (blue pimpernel, 55.6%), Asphodelus tenuifolius (jungle onion, 42.3%), Chenopodium album (common goosefoot, 40.8%), Circium arvense (creeping thistle, 53.1%), Convolvulus arvensis (field bind weed, 56.6%) and Cynodon dactylon (vilfa stellata, 45.8%) within 60 days after sowing (DAS) as compared with the control treatment (three cultivations on a wheat fallow cropping system). Similar trends were observed at the crop maturity stage. Results of the experiment showed that better weed biomass suppression can be achieved by using moldboard plough for cultivation with followed by wheatbrassica cropping system and/or wheat chickpea intercropping for semiarid soil condition in Pakistan.

期刊介绍:
Planta Daninha is a scientific journal published by the Brazilian Society of Weed Science (SBCPD - Sociedade Brasileira da Ciência das Plantas Daninhas). Papers submitted for publication must be sent through an electronic system, on http://www.scielo.br/pd. Works may be written in Portuguese, English, or Spanish, and will be accepted after being reviewed and approved by the Editorial Board. Only papers that have not been published or submitted for publication in other media will be accepted. Articles in Portuguese will be translated to English after being properly corrected and authorized by the authors. Planta Daninha has with goal to publish genuine technical-scientific papers and literature reviews from a critical perspective on Biology, weed management, and related topics.
