	%X Intercropping is one of the sustainable agricultural
factors. The SPAD meter can be used to predict nitrogen index
reliably, it may also be a useful tool for assessing the relative impact
of weeds on crops. In order to study the effect of weeds on SPAD in
corn (Zea mays L.), sweet basil (Ocimum basilicum L.) and borage
(Borago officinalis L.) in intercropping system, a factorial experiment
was conducted in three replications in 2011. Experimental factors
were included intercropping of corn with sweet basil and borage in
different ratios (100:0, 75:25, 50:50, 25:75 and 0:100 corn: borage or
sweet basil) and weed infestation (weed control and weed
interference). The results showed that intercropping of corn with
sweet basil and borage increased the SPAD value of corn compare to
monoculture in weed interference condition. Sweet basil SPAD value
in weed control treatments (43.66) was more than weed interference
treatments (40.17). Corn could increase the borage SPAD value
compare to monoculture in weed interference treatments.
