Özet

The present research was conducted to determine the effect on the yield and yield components of different seeding systems of wheat and pea intercropping at the Research Area of Field Crops Department of Agricultural Faculty within Cukurova University. Field trails were organized in randomized complete blocks design with four replications at the end of November in 2014 and 2015. Grain yields in the intercropped pea and wheat were less than sole crops. Increasing pea rate in the mixture seeding provided good competition with wheat. The highest grain yield of intercropped pea was found in the intercrops including 85% of pea seeds in alternate row in both years and combined years. Total grain yield of intercrops was higher than sole crop pea, but it was lower than sole crop wheat. Total grain yield of intercrops including 50 % pea at the same row was higher when compared to the other intercrops in both of years and combined years. On the other hand, it was found that generally, LER value for grain in the intercrops was greater than 1 and intercrops use environmental sources such as water, soil, and light for plant growth factors more efficiently than the sole crops for grain production.
