Abstract

To study the effect of plant density on three soybean cultivars on 2008 at Mashhad region an experiment was conducted as factorial based on Randomized Complete Blocks Design with 4 replications. The experimental factors was included of three cultivars i.e. Hobit, Williams and LWK with three plant density that was 30, 45 and 60 plant/m 2 . In each of three cultivars with increasing plant density, yield components decreased such as fertile node number, pod number on main stem, branch number, node number on branch and total pod in each plant. But plant height, lowest height of pod from the earth, node number on main stem, pod number on main stem node, seed number in each main stem pod, 100 seeds weight of main stem were not affected by plant density. Based on received results from the experiment, by increasing plant density, leaf area index, crop growth rate, biological and economical yield increased. Yield of cultivar Hobit with least plant height, the most short growth period duration, least biological yield and highest harvest index, was more than other cultivars and cultivar LWK showed minimum yield among three cultivars. Hobit and LWK at density 60 and 30 plant/m 2 with yield 5024 and 3378 kg/ha respectively, showed the most and least economical yield among the all of treatments.
