بررسی فنی اقتصادی اثر روش های مختلف کشت بر روی عملکرد لوبیا چیتی در استانهای مرکزی و زنجان

In order to study on effect of planting patterns on bean yield and their economic comparison in Markazi and Zanjan provinces, an experiment was conducted in two years. The experimental design was split plot arrangement of treatments in a randomized complete block with three replications. Two chiti bean cultivars (Khomein local and COS16 line) were arranged in the main plots and four level of planting method (manual planting, furrow planting, cultivator planting and mechanical planting) were considered in the sub plots. The results indicated that the effect of various planting methods on number of seeds per pod, number of seed in plant and seed yield were significant in 1% level of probability and in number of pod in plant was significant in 5% level of probability; but these effects weren't significant on 100 seed weight. Seed yield in mechanical planting, furrow planting and manual planting without significant difference among them, were more than cultivator planting. There was significant difference between bean cultivars in 5% level of probability in yield, too. COS16 line with 2815/5 kg/ha; had more yield than Khomein local (about 163 kg/ha). Results in Zanjan showed that planting pattern of bazrkar for COS16 variety was economic choice. Also planting pattern of furrow for Khomein variety was economic. In two years of experiment in Khomein planting pattern of bazrkar for COS16 variety was economic choice. Also in this location, planting pattern of cultivator for Khomein variety was economic.
