Annual medic is an annual crop which performs well in various forage cropping systems. However availability of medic seeds is a major challenge for livestock producers in Iran. This study was conducted to determine if intercropping annual medic with barley can produce supplement medic seeds while barley grain yield as the main crop is not compromised. Two experiments were carried out at the exp...

introduction multiple cropping such as intercropping plays an important role in agriculture because of maximizing beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture that dates back to ancient civilization. maize-legume intercrops could substantially increase forage quantity and quality and decrease requirement for protein supplements (ahmad ...

in order to evaluate the effects of yield and yield components and weed diversity and density in row intercropping for wheat and canola, a field experiment was conducted based on a complete randomized block design with three replications at the agricultural research station of ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments included four pa...

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...

Sustainable agriculture seeks to at least use nature as the model for designing agricultural systems. Since nature integrates her plants and animals into diverse landscape, a major tenet of sustainable agriculture is efficiency and lack of waste products in nature. When domestication of crops replaced hunting and gathering of food, landscape changed accordingly. By producing a limited selection...

A pot experiment and afield trial were conducted to study the remediation of an aged field soil contaminated with cadmium, copper and polychlorinated biphenyls (PCBs) (7.67 +/- 0.51 mg kg(-1) Cd, 369 +/- 1 mg kg(-1) Cu in pot experiment; 8.46 +/- 0.31 mg kg(-1) Cd, 468 +/- 7 mg kg(-1) Cu, 323 +/- 12 microg kg(-1) PCBs for field experiment) under different cropping patterns. In the pot experimen...

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...

abstract to find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, zanjan university in year 2004. different potato to maize ratios of (1:0), i.e...

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...

Creating conditions that enhance the abundance of resident populations of natural enemies in agroecosystems is considered critical to the efficiency of biological control of insect pests. We conducted a study to determine the potential of relay-intercropping for enhancing the abundance of aphidophagous lady beetles in sorghum. A relay-intercropping system consisting of alfalfa, winter wheat, an...
