چکیده
On-farm production of protein is limited in most dairy farm operations in arid

and semi-arid environments. Cereal-legume intercropping could be a viable option

to obtain forage with higher protein content. A two-year experiment was conducted

during 2009 and 2010 growing seasons in a loamy soil to determine whether

intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medicago

scutellata L.) could increase forage quality while producing sufficient amount of

forage yield. The results showed that when number of rows in 50:50 replacement

intercropping decreased from six rows of barley and six rows of medic (6B:6M)

(strip intercropping) to 4B:4M, 2B:2M and 1B:1M, barley forage yield increased

by 9, 18 and 24% due to a wavy canopy created by 1B:1M and 2B:2M cropping

ratios. Land Equivalent Ratio (LER) was highest (1.19) when barley was

intercropped with annual medic in 1B:1M arrangement indicating that 19% more

area would be required by a sole cropping system to yield similar of intercropping

system. The highest protein yield was also obtained from 1B:1M ratio. Pure stand

of annual medic had the highest Crude Protein (CP) content (310.7 g kg-1 of DM)

whereas sole cropping of barley had the highest Neutral Detergent Fiber (NDF) and

Acid Detergent Fiber (ADF). When both forage yield and quality was considered,

the intercropping of barley and medic with 1B:1M ratio was superior to any other

ratios and can be recommended to farmers as an alternative to barley alone.
