Strong benefits of species diversity have been demonstrated in mixed cropping on rangelands. In order to determine the best composition of mixed cropping of alfalfa (Medicago sativa) with three cool season grass species (Agropyron elongatum, Agropyron desertorum and Festuca arundinacea), on yield and quality traits, an experiment was conducted during two years (2009 and 2010) in Bojnourd, Iran....

BACKGROUND AND AIMS In the UK, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year. The fruits of hedgerow plants are a source of winter food for frugivorous birds on farmland. It is unclear whether recent declines in pollinator populations are likely to threaten fruit-set and hence food supply for birds. The pr...

Onattukara sandy loam tract an important agro ecological zone spread over the Karunagapally taluk of Kollam and Karthikapally and Mavelikara taluks of Alappuzha districts of Kerala. The soils are highly permeable, acidic in reaction and are extremely deficient in all the major plant nutrients. Sesamum is mainly grown in Kerala as a sole crop in the summer rice fallows of Onattukara tract. The c...

Soybean/maize intercropping has remarkable advantages in increasing crop yield and nitrogen (N) efficiency. However, little is known about the contributions of rhizobia or arbuscular mycorrhizal fungi (AMF) to yield increases and N acquisition in the intercropping system. Plus, the mechanisms controlling carbon (C) and N allocation in intercropping systems remain unsettled. In the present study...

Compounds released by mungbean roots potentially represent an enormous source of nitrogen (N) and carbon (C) in mungbean-oat intercropping systems. In this study, an in situ experiment was conducted using a 15N - 13C double stem-feeding method to measure N and C derived from the rhizodeposition (NdfR and CdfR) of mungbean and their transfer to oats in an intercropping system. Mungbean plants we...

to evaluate the yield components, yield and land equivalent ratio affected by relay intercropping of sunflower (helianthus annuus l.) with faba bean (vicia faba l.), a field experiment was arranged based on a randomized complete block design with three replications at the agricultural research station payamenoor university of nagadeh, iran during growing reason of 2012-2013. the treatments incl...

in order to study yield and yield components in intercropping bean (phaseolus vulgaris l.) and sweet basil (ocimum basilicum l.) and evaluating effect of intercropping on weed control, a field experiment was conducted at the agricultural research station, ferdowsi university of mashhad during growing season of 2008. treatments: included 1- sole crop of bean 2- sole crop of sweet basil 3- strip ...

This study was aimed at quantifying soybean (Glycine max) nitrogen fixation under reduced tillage (RT) and conventional tillage (CT) in a tropical Ferralsol of the sub-humid zone of western Kenya, using the isotope N dilution method. Crop residue (CR) management was a superimposed treatment in soybean-maize rotation and intercropping systems. This study quantified N in abscised soybean leaves. ...
