Abstract

In order to evaluation of some growth indices of potato and safflower intercropping system in ardabil region, a spilit plot experiment based on randomized complete block design with three replications was conducted at research field of Mohagehge Ardabiliy university in 2009. Treatments compositoin were: 1: 0 (net culture potato, six plants per square meter), 1: 1 (with a density of 6 potato and 6 safflower plants per square meter), 2: 1 (with a density of 6 potato and 12 safflower plants per square meter) and 3: 1 (with a density of six potato and 18 safflower plants per square meter). Results showed that in case of safflower, with increasing of growing degree days (GDD), the total dry matterincreased initially and decreased over time. Also RELATIVE GROWTH RATE (RGR) was decrease at over time and was negative at the end of the growing season.Safflower relative growths rate decreased with time, and reaches zero and then became negative. With increasing safflower contribution at the intercropping tratments, dry matter and CROP GROWTH RATE (CGR)demonstrated increasing trendand RELATIVE GROWTH RATE and LEAF AREA INDEX (LAI)) showed an deacreasing trend. In pur culture of potato with increasing GDD, total dry matter was increased. Also CGR and LAI initialy increased and then decrased. Also with incraseing GDD, RELATIVE GROWTH RATE was decreased at the pure culture of potato. The results indicate thattreatment compositoinof 3: 1 (with a density of six potato and 18 safflower plants per square meter) because of the high dry matter and high grotwth rate of canopy in too plants compared to other treatments may be appropriateat similar conditions of the present study.
