Effect of Cowpea (Vigna unguiculata (L.) Walp.) Sowing Times Applications on the Yield and Yield Components
Abstract
In this research, it was aimed to determine the most suitable sowing time for cowpea in Eastern Turkey. Two cowpea genotypes (Oba and Evci) were sown at three different sowing times (15 April, 30 April and 15 May). The trial was conducted in the experimental fields of Agricultural Faculty of Yuzuncu Yıl University by using randomized split block design with the three replications in 2008 and 2009 years. Experiment was established genotypes as main plots and sowing times treatments as split plots. In the study were investigated the effect of sowing time on the plant height, numbers of branche, numbers of pod per plant and numbers of seed per plant, numbers of seed per pod, seed yield, harvest index, biological yield and 100 seed weight. While the highest mean seed yield was obtained from 30 April sowing with 1163 kg ha -1, the lowest seed yield per area was obtained from 15 May with 1088 kg ha -1. The results of the study indicated that sowing time (30 April) application increased significantly the seed yield. Oba population gave higher seed yield than Evci population
