Evaluation of Yield and Resistance Effect of Some Yam Genotypes (Dioscorea rotundata Pior) to Pest Attack at Harvest in Uyo, Southeastern Nigeria
Journal Title: American Journal of Agricultural Science, Engineering, and Technology - Year 2021, Vol 5, Issue 2
Abstract
Two years study was carried to assess level of resistance to yam beetle and termite attack by some yam genotypes in Uyo, southeastern Nigeria. The experiment was laid out in randomized complete block design replicated three times. The five yam genotypes tested for yam beetle and termite attack at harvest were; TDr 95/19127, 95/18894, 95/19531, 75/1/2 and Uyo popular local variety eteme. The results showed variations in yield and susceptible to termite and beetle attack at harvest. The TDr 75/1/2 had highest yield 30.41 and 29.75t/ha, followed by TDr 95/18894, 28.86 and 27.93t/ha in 2008 and 2009 respectively. The local variety had lowest yield 9.75 and 10.07 t/ha in 2008 and 2009 respectively. The local variety had 14.58% termite attack in 2008 while 95/19127 had 12.64% in 2009. The local variety had highest beetle attack 45.83% and 32.76% in 2008 and 2009 respectively. The least prone to termite and beetle attack was recorded in TDr 75/1/2, 2.72 and 8.15% respectively in 2008 and 2.99 and 6.59% in 2009 respectively. The study suggested that TDr 75/1/2 and 95/18894 should incorporate in the farming system of the study area due to their high yielding capacity and resistance to pest attack at harvest. Â
