Abstract

To study the evaluation of GRAIN YIELD and dry matter remobilization of barley, cultivar Jonoob, under planting pattern and seeding rate treatments, a research was carried out as strip plot in randomized complete block design with 3 replications in Ramin Agriculture and Natural Resources University of Khuzestan, Iran, during 2013-14 cropping season. The experimental treatments were including four planting pattern (flat planting with 17 cm distance of rows, flat planting with 25 cm distance of rows, 3 rows on ridges with 50 cm wide and 2 rows on ridges with 50 cm wide) as first factor and four level of seeding rate (200, 300, 400 and 500 seeds/m2) as second factor. Results showed that the maximum leaf area index, 1000-grain weight, GRAIN YIELD (5072.1 kg.ha-1) and biological yield (13250.2 kg.ha-1) obtained in flat planting with 17 cm distance of rows. Day to ear emergence, grain number per spike and GRAIN YIELD decreased by increasing the seeding rate, but the number of spike per m2 increased. The interaction effects of planting pattern and seeding rate were significant on the REMOBILIZATION EFFICIENCY and contribution of the remobilization in GRAIN YIELD. Three rows on ridge method has more sensitive to changes of the seeding rate, so the CONTRIBUTION OF REMOBILIZATION in GRAIN YIELD significantly increased with the increasing of each unit in seed rate. This indicates that decreasing of the row spacing together with more utilization of the seeds increased dependence of the grains to storage materials through intensified competition, decrease of the light penetration into the canopy and acceleration of the leaves chlorosis.
