to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...

Liriomyza sativae and L. trifolii are highly invasive leafminer pests of vegetable crops that have invaded southern China in recent years. Liriomyza sativae was the first of these species to invade China, but it is now being displaced by L. trifolii. The rate and extent of this displacement vary across southern China. In Hainan, monocultures of highly valuable cowpea are planted and treated ext...

Soil N is a major factor limiting crop production in maize-based agriculture in the tropics. In this study, soil N dynamics and efficiency of N use by maize was investigated in five cropping systems (CSs) over two annual cropping phases. The CSs comprised cereal-legume (CS1, CS2, CS3), cereal-cereal (CS4) and cereal-bare fallow (CS5) rotations with three rates of N fertiliser application to mai...

in order to evaluate radiation capture and use efficiency and productivity in sole and intercropping of three crops, rapeseed (brassica napus l.), bean (phaseolus vulgaris l.) and corn (zea mays l.), an experiment was conducted in mashhad region during the growing season of 2007-2008. in this study six treatments including three sole cropping of the crops (rapeseed sown in 22 september 2007, co...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...

The current study evaluated the impact of intercropping Cowpea and Moong bean on Maize yield its constituent parts. Nine different treatments were used in experiment viz., (T1) sole Maize, (T2) Cowpea, (T3) bean, (T4) + (1:1), (T5) (1:2), (T6) (1:3), (T7) (T8) (1:2) and, (T9) (2:1) a randomized block design with three replications Kharif season. findings showed that intercropped plants had grea...

in order to evaluate intercropping of barley (hordeum vulgare) and vetch (vicia vilosa ler ssp. desycarpa), two field experiments were conducted on the farm of the university of tehran, karaj, iran in 2004 and 2005. a split plot experiment based on randomized complete block design (rcbd) with four replications was used in this study. nitrogen was the main factor (0, 45 and 90) and sub plot fact...

The application of zinc to some selected legumes (cowpea - Vignaunguiculata L. Walp., soybean – Glycine max Merr. or mungbean Vigna radiate Wilczek) intercropped with upland rice (OryzaesativaL.) may improve the presence residual nitrogen in cropping system andprotein in-take farmers faced protein and mineral deficiency, especially their daily food menu. Information on effect is inadequate...
