Agronomic performance of intercropped wheat cultivars

Abstract

A field study was carried out to assess whether intercropping of three commonly used cultivars of wheat in Iran with different height may increase seed yield. Seed yield three wheat cultivars which differed in were investigated at educational field of Gonbad Agricultural Faculty in 2005-2006 (Iran). The statistical design was factorial 3 plant densities of 300, 350 and 400 seed in m2 with 6 intercropping ratios of Kohdasht, Tajan and Zagros (3 pure stand and 3 50:50 intercropping of Kohdasht, Tajan and Zagros cultivars, respectively) in completely randomized blocks. The results showed that none of the treatments has no significant effect on yield. The results indicated that the highest seed yield was obtained from 50:50 ratios of Tajan-Zagros cultivars in density plant 400 of seed in m2 which had Land Equivalent Ratio (LER) above 1.25 Calculation of LER revealed that seed yield in treatment TZTZTZ was 25% higher than the pure stand. Intercropping ratio showed no significant effect on any of yield components. © 2009 Asian Network for Scientific Information.
