To evaluate forage production and land equivalent ratio (LER) in additive and replacement intercropping systems of forage sorghum and berseem clover, a field experiment was conducted using randomized complete block design with eight treatments and three replications at the research field station of Seed and Plant Improvement Institute, Karaj, Iran, in 2016-17 and 2017-18 growing seasons. The ex...
To study the effect of fertilizer and planting pattern on chickpea and linseed plant traits in dryland farming, a field experiment was conducted in factorial layout based on randomized complete block design with three replications in Naqadeh, Iran during growing season of 2016-2017. Treatments were included six substitutive cropping patterns; sole cropping of chickpea, sole cropping of linseed,...
Weed competition is a significant problem in maize (Zea mays, L.) production in Sub-Saharan Africa. Better understanding of weed management and costs in maize intercropped with beans (Phaseolus vulgaris, L.) during transition to conservation agricultural systems is needed. Changes in weed population and maize growth were assessed for a period of three years at Bungoma where crops are grown twic...
ارزیابی عملکرد اقتصادی و کارایی مصرف نور در کشت مخلوط و خالص ذرت و پنبه تحت تاثیر سطوح مختلف نیتروژن
In order to study the potential of maize-cotton intercropping for improving radiation use efficiency (RUE), an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications at experimental filed of Ferdowsi University of Mashhad. The experimental treatments were nitrogen in four levels (0, 50, 100 and 150 Kg N ha-1) and planting pattern ...
In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), b...
Under a changing climate, harvesting management and exploiting the genotypic divergence of Egyptian clover cultivars offers biologically viable solution to sustainably boost milk productivity dairy animals. Two multi-season field trials were executed under semi-arid conditions whereby first experiment aimed assess potential (Berseem Agaiti, Anmol SB-11) for nutritional quality attributes digest...
Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil nutrients and sustain use of spray field, best management practices must maximize the rates of removal of manure nutrients. Research determined summer hay and nutrient yields of bermudagrass [Cynodon dac...
in order to evaluate the weed diversity in forage crop fields such as alfalfa (medicago sativa l.), clover (trifolium sp.) and sainfoin (onobrychis spp.) in different provinces of iran, a study was conducted by using data from reports of plant protection organization, ministry of agriculture during 2008. after evaluation of weed species and definition of weed family, these species classified ba...
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...
