Abstract

In order to study the growth pattern and competition effect, an experiment of INTERCROPPING SOYBEAN cultivars was conducted during the 1999-2000 growing season at the agricultural experimental farm of Tehran University. In this study some of the GROWTH INDEXes in sole culture and INTERCROPPING were evaluated. The experimental design was a factorial with 3 replications in which the first factors were 3 different plant densities (20, 40 and 80 plant per 1 m2). Second factors were five different cropping rations (100:0, 75:25, 50:50, 25:75 and 0:100 Hag and Clark 63 cultivars, respectively). The results showed that, the maximum total dry matter yield and crop growth rate (CGR) were observed in 50% Hag+50% Clark with 80 p/m2. The highest leaf area index (LAI) was produced in sole crop of Clark and 50% Hag+50% Clark. However, the mixture of 50:50 had higher leaf area duration in the end of growth season. it concluded that Clark may use light more efficiency in the end of growing season, because of longer leaf duration. In addition the highest relative growth rate (RGR) was achieved in mixture of 50:50 Hag/Clark and sole crop of Clark at the beginning of the season. The maximum of net assimilation rate (NAR) also were obtained in sole crop of Hag., but it reduced earlier in compare with other treatments. Finally the leaf area ratio (LAR) of all' mixture was more than sole crop of Hag, and less then sole crop of Clark.
