Response of Wheat Genotypes to Planting Dates in the Arid Region
Journal Title: Scientia Agriculturae - Year 2015, Vol 10, Issue 2
Abstract
To evaluate the genotypic response of wheat crop under arid land conditions, a field experiment was conducted at agronomic research station of King Abdulaziz University, Hada Al-sham, Jeddah Saudi Arabia. Five wheat genotypes (Ucora Rojo, F-101, F-50, F-10 and sama) were studied under four planting dates (Nov. 15, Dec. 01, Dec. 16 and Dec 31) for their tolerance and adaptability to severe arid land conditions. Experiment was conducted in randomized complete block design with three replicates. Statistical analysis of the recorded data illustrated variable response of planting dates and genotypes to studied growth and yield traits. December 16 plantation brought an overall increment of 20% for Plant height, 17% for productive tillers, 33% for spike length, 75% for spikelet per spike, 85% for grain weight per plant, 7% for 100 grain weight, 21% for grain yield per ha and 15% for harvest index over rest of the planting dates. While genotypes presented higher variation to these studied traits as obvious from level of improvement viz., 29%, 59%, 164%, 166%, 179%, 111%, 203% and 46% for F-10 and F-50 for all these studied traits respectively. Interaction of genotype F-10 and F-50 × December plantation was the most suitable combination that represented highest level of adaptability to arid environment (in term of drought and heat tolerance) as expressed by their better growth and yield.
