Abstract
In order to consider effects of seed deterioration and seedling germinate on soybean grain yield in cv. Sahar, an experiment was carried out, as randomized completely block design with four replications in field Agriculture Science and Natural Resources University at Gorgan, Iran in 2010. The treatments of seed deterioration were given at seven levels (0, 7, 14, 21, 28, 35 and 42 days). One treatment was from area storages. Results showed that germinate percentage and germinate rate were decreased by increase in deterioration period. Percentage of normal seedling from 84 % by 7 days demising came 55 % by 35 days demising. Planting density decreased by increase in deterioration period meanwhile planting density decreased 0.23 plants per m 2 with increase each day to deterioration period. Flowering time and pod feeding were affected by seed deterioration treatment, so that flowering time for control was 41 days after planting but in 35 days deterioration treatment was 46 days after planting. The other phonological stages weren’t affected by deterioration treatments. Grain yield decreased by increase in deterioration period and grain yield decreased 4.03 g by increasing of each day in seed deterioration period. Yield components didn’t affected by seed deterioration. Therefore results showed that grain yield decreased by increase in deterioration period but this reduction was related to decrease in planting density.
