Producers are interested in tactics for managing crop residues when growing corn after spring wheat. We compared five systems of managing spring wheat residues: conventional tillage, no-till, strip-till, cover crop (hairy vetch) with no-till, and cover crop with strip-till following spring wheat. Conventional tillage consisted of chisel plowing and disking, whereas strip-till consisted of tilli...
Conservatiion with respect to physiological aspects of crops is a crucial factor for ideal photosynthesis and appropriate yield in arid and semi-arid agro-ecosystems. In order to investigate the effect of planting pattern on stability of physiological parameters of fenugreek and black cumin under drought stress, an experiment was conducted in the University of Shahrekord in 2014. Three drought ...
BACKGROUND: Application of plant mulches plays a significant role in development and expansion of sustainable farming systems. OBJECTIVES: Assessment effect of chemical and non-chemical weeds management methods on weeds density and biomass and the properties of soil, including microbial biomass carbon (MBC) and soil organic carbon (SOC) in potato cultivation. ...
A field experiment was carried out during the 2017-18 cropping season at Jinka Agricultural Research Center on station, South Omo zone, Southern Ethiopia, to determine suitable legumes in cassava legume intercropping yield and land use efficiency of both crops. The consisted 7 treatments (cassava with haricot bean, cowpea, pigeon pea as intercrop compared cassava, cowpea sole) laid RCBD three r...
in order to evaluate intercropping of summer savory (satureja hortensis l.) and persian clover (trifolium resupinatum l.), an experiment was conducted at agricultural research station of ferdowsi university of mashhad in 2004 growing season. treatments were sole cropping of persian clover (eight rows), double-row intercropping of persian clover and summer savory with 27, 40 and 80 plants.m-2 (e...
introduction weed infestation causes an extremely reduction of crops yield. on the other hand, increasing the diversity of crops in agro-ecosystems will change the biomass distribution of weeds community, thereby reducing the number and density of different weed species. weed management in the past few decades has been in conflict with ecological principles and sustainability of the production ...
in order to evaluation the effect of mixed cropping on yield and agronomical characteristics of wheat (triticum aestivum l.) varieties, a field experiment based on a randomized complete block design with four replications was carried out at city of mahvelat in khorasan razavi province, iran, during growing season of 2007-2008. treatments including five sole cultures of conventional wheat cultiv...
Weed control through crop rotation has mainly been studied in a nonspatial context. However, weed seeds are often spread beyond the crop field by a variety of vectors. For weed control to be successful, weed management should thus be evaluated at the landscape level. In this paper we assess how seed dispersal affects the interactions between crop rotation and landscape heterogeneity schemes wit...
In order to determine the best intercropping combination of wheat (Triticum aestivum) and rapeseed (Brassica napus) based on total yield and landuse efficiency, an experiment was conducted during 2010-2011 growing season at Agricultural Research Farm of Faculty of Agriculture, Bu-Ali Sina University. This experiment used randomized complete blocks design and three replications. Treatments inclu...
In order to investigate the effect of bio-fertilizers on the effective physiological characteristics and to improve the performance of common bean (Phaseolus vulgaris L.) and black cumin (Nigella sativa L.) in different ratios of intercropping, a field experiment was conducted as a factorial based on a randomized complete block design with three replications; this study was carried out at the r...
