RESPONS OF FORAGE YIELD OF BARLEY AND CLOVER TO THE INTERCROPPING

Abstract

A field experiment was carried out in 2013 in one Euphrates side’s farms in west region of Iraq, 150 km west of Baghdad, using randomized complete block design (RCBD) with three replicates in order to study forage of barely (hordeum vulgare L.) and clover (Trifolium alexandrinum .L) intercropping at seeding rate Barely-Clover % (75-25, 50-50, 25-75). Dry matter (DM), land equivalent ratio (LER) and Aggressivety (A) were calculated. The results showed the following: seeding rate significantly affected in dry matter where seeding rate 75% barely-25% clover gave the highest average of DM. The intercropping has recorded values larger than 1 for LER under all seeding rates. The seeding rate 50%-50% gave highest value of LER for the sum of forage cutting. Barely showed high ability to compete which has recorded positive values of A while clover showed less ability to compete which has recorded negative vales. It can be concluded that intercropping is valuable in land exploiting
