Abstract:

Planting arrangement through the impact of growth physiological indexes effect on grain yield. In order to survey these influences in fall cultivation of safflower, Zhilla cultiver was tested in 2011.This experiment was done in Mahidasht farm in Kermanshah as factorial randomized complete block design with three replications. Planting row interval treatments consists of 25, 35 and 45 cm and plant interval treatments on planting row consists of 10, 15 and 20 cm. In this experiment the physiological growth indexes consists of leaf area index, plant dry weight, product growth rate, relative growth rate, net assimilation rate and grain yield were evaluated. The results showed that the effects of planting row interval and plant interval on row on the mentioned physiological indexes were significant. By reducing the planting row interval (25 cm to 45 cm) and reducing the plant interval on row (20 cm to 10 cm) due to uniform distribution of plants, Plant vegetation was completed faster and the plant uses well of sunlight and environmental factors, and enhances the dry matter accumulation, leaf area index, crop growth rate, relative growth rate, net assimilation rate and seed yield (70%-35%) .
