Effects on Yield Components and Seed Yield of Some Feed Pea (Pisum sativum ssp. arvense L.) Varieties at Different Sowing Times

This research was conducted in Agricultural Application and Research Center, Igdir University, 2018-2019 and 2019-2020, as a randomized complete block design in split plots with three replications. Seed yield and some other yield components of four different feed peas (Kirazli, GAP Pembesi, ozkaynak and Taskent) cultivar were determined in 6 different sowing times (early March, late March, early April, late October, early November and end of November). In the research, the maturation time of the feed pea (MT), the number of pods per plant (PN), the number of seeds per pod (SN), biological yield (BY), seed yield (SEY), straw yield (SY), harvest index (HI), thousand grain weight (TGW) were determined. Results indicated that, the BBS, BTS, SV, TV and BV values in the second year of the study were higher than the first year. It was concluded that seed sowing should be done at the beginning of March in order to obtain high biological, seed and straw yield in feed peas. It was determined that Kirazli variety was better in terms of seed and hay yields. As a result, it was determined that in the case of selecting the Kirazli variety, the higher biological, seed and straw yield could be obtained by sowing it in early March under the region conditions.
