Abstract

Abstract
This experiment was carried out for assessment of sesame and chickpea intercropping under climatic condition of Mashhad. The Experiment included main factor A (planting methods) whit two levels a1(row planting) and a2(mixed planting) and factor B (replacement planting pattern) consisting of five levels b1 (chickpea monoculture), b2 (75% chickpea+25% sesame), b3 (50% chickpea+50% sesame), b4 (25% chickpea+75% sesame) and b5 (sesame monoculture) and was carried out in context of split plot based on randomized complete block design with three replications. results indicated that was significantly affected land equivalent ratio, that 50% chickpea+50% sesame and 75% chickpea+25% sesame row ratios with 1.46 and 1.34 respectively had the most and treatment 25% chickpea+75% sesame mixed with 0.94 had the least land equivalent ratio. So, according to these results, intercropping of sesame and chickpea with ratio of 50% optimum density of chickpea + 50% optimum density of sesame and 75% optimum density of chickpea + 25% optimum density of sesame under climatic condition of Mashhad is considerable.
