Evolution of Intercropping of three Sesame Cultivars (Sabzevar, Kashmar, Kalat) on Seed Yield and Yield Components Indices

In order to study the effect of inter cropping (Blend) of three sesame (Sesamum indicum L.) cultivars (Sabzevar، Kashmar، Kalat) an experiment was conducted as a factorial based on Complete Randomized Block Desing with 3 replications at Research Farm Ferdowsi University in 2009. The experimental treatments were obtained: sole cultivation of Sabzevar، Kalat، Kashmar، and their mixed crops (1. Sabzevar with Kashmar، 2. Sabzevar with Kalat، 3. Kalat with Kashmar). The results showed that highest and lowest studied traits (including: biological and seed yield، the number of capsules on main stem and branches، number of seeds per capsule and seed weight) obtained in Sabzevar-Kashmar and sole cultivation of Kalat respectively. Generally Sabzevar in mix with other cultivars increased total yield seed، and Kalat and Kashmar Cultivars in mixed with Sabzevar cultivar had the highest positive effectives. And mix of Kashmar and Kalat cultiavars had the lowest indicator amount. Also mix of Sabzevar with Kashmar cultivars and mix of Kalat with Kashmar cultivars had the highest (1/14) and lowest (0/93) Land Equivalent Ratio (LER). Based on the results of this experiment mix of Sabzevar with Kashmar is best treatment in order to achieving high seed yield of sesame in Mashhad area.
