Abstract
The research study was carried out in Pakistan's Dera Ismail Khan (KPK) at the Arid Zone Research Centre. During 2017-18 on seventeen wheat Varieties/advance lines (C-2014, PR 112, A-2014, DN-84, PR 105, Atta Habib, KT 2000, Shahkar-2013, Pak-2013, Dharabi 011, PS 2005, Tatara, Lalma-2013, Zam-04, Chakwal-50, Hashim-08, Yarik) to compare their yield performance by delay sowing in season under rainfed condition. Sowing of wheat in rainfed area of Dera Ismail khan often depends on winter rainfall which may delays its planting in the season. Between November 10 and December 20, there were five planting dates that were spaced 10 days apart in a 3 replications of a split-plot layout in a randomised complete block design. The impact of planting dates on types and advance lines was examined using both main plots and sub plots. On days to maturity, the data were kept, spike length, grains/spike, 1000-grain weight and yield. The interaction between planting dates and types has a considerable impact on wheat grain production and its characteristics. Wheat varieties Lalma-2013 and Chakwal-50 produced highest yield on Nov. 10th sowing with minimum reduction in grain yield as 2.6% and 1.2% respectively on Nov.20th sowing. The Lalma-2013 and Chakwal-50 could be the best varieties for the rainfed areas of Dera Ismail Khan as compared to local varieties when sown not later than 20th Nov. [ABSTRACT FROM AUTHOR]
