Abstract
Pea (Pisum sativum L.) is belongs to the Leguminosae family and currently grown in most temperate regions of the world. The research was carried out between February and June 2022 in the Dicle University, Faculty of Agriculture, in Diyarbakır, Turkey. In the experiment, four different plant densities (40, 60, 80, 100 seeds per square meters) were used in the Utrillo pea cultivar. The experiment was carried out the randomized complete blocks design with three replications. Plant rows were harvested every 10 days 45 days after sowing for plant height, number of nodes, leaflets, leaves and stipules per plant and leaf area. Crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR), absolute growth rate (AGR), leaf area index (LAI), leaf area ratio (LAR), leaf area duration (LAD), specific leaf area (SLA), specific leaf weight (SLW) values were calculated. All traits were affected by plant density. The plant height varied between 28.50 and 34.83 cm, and plant height decreased as increased plant density. The number of stipules per plant ranged from 7.94 to 9.50, and dense plant densities increased the number of stipules per plant. The highest crop growth rate (CGR) values from 45 days to 85 days during growth season were in DAE 85 and in 80 seeds per m2. The highest RGR value was in DAE 55 and in 100 seeds per m2. The highest plant density, 100 seeds per m2, was produce high value of leaf area index (LAI).
