Ankara koşullarında bazelye (Pisum sativum L.) da farklı ekim zamanlarının verim ve verim öğelerine etkisi
Özet
This research was conducted in the experimental field of the Field Crops Department of Agriculture Faculty of Ankara University, in 1996. The aim of this research was to determine the most convenient sowing time of three pea varieties grown under climatic conditions of Ankara. For this reason, seeds of three varieties (Winner, Karina and Manuela) received Dardanel-önentaş Food Industy Corporation and having production permission were sown in split plots of randomized blocks with four replication at three different sowing times (27 th March, 09 th April and 22 nd April). According to the results of this research, the differences among varieties regarding plant height and pod height was significant. However, the difference among sowing times was significiant. it was also found out that sowing time was important on the properties of pod weight and seed weight of a plants, it was observed that plant weight, pod number per plant, seeds numbers per plant, harvest index, yields of different varieties, sowing times were found to be seperately effective. Variety-seeding time interreaction is determined only in a hundred seed weight. The first and second sowing times (27 th March- 09 th April) produced similar results in all three varieties, where as third sowing time (22 nd April) resulted in reductions in data obtained. Although seed yield was effected by cultivars, delay in sowing time had negative effect on yield.
