Study of maize and sunflower intercropping

To study the intercropping system of maize and sunflower an experiment was Conducted at Jiroft Agricultural Research Center In 1376 cropping . Experimental design was R , C . B . D . with five treatment and three replication. The Treatment were as fallows : M1 : sole cropping of maize M2 : 75 % maize + 25 % sunflower M3 ; 50 % maize + 50 % sunflower N4: 25 % maize + 75 % sunflower M5: sole cropping of sunflower . The plants were planted as replacement method . calculation LER indicate that Ms treatment of intercropping system of 75 % maize + 25 % sunflower had highest fresh matter , dry matter grain yield and total protein in the region . Also this treament had higher efficiency in term of using of moisture as well. In general the Ms treatment could be recommended for high Yielding cropping system in this region.
