A field experiment was conducted at research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu on sandy loam soil of Sub-tropical zone of Jammu division to investigate the effect of sowing dates and genotypes on growth, yield and nitrogen uptake of durum wheat (Triticum durum) for two consecutive rabi seasons. The treatments comprised of two sowing dates viz. D1-normal sown and D2-late sown in the main plot, and four genotypes viz. PBW-34, PDW-233, WH-896 and PBW-343 in the sub plots were evaluated under split plot design with three replications. Results revealed that variety PBW-343 recorded significant higher number of ear heads, grain and biological yield per m2 area than that of all other genotypes. Among sowing dates, normal sown wheat crop recorded significant higher grain and biomass yield as compared to late sown wheat. In normal sown wheat (D1), N uptake in grain was also recorded significantly higher in both the consecutive years whereas, among different genotypes, PBW-343 recorded highest N uptake in grain and straw in second year of cropping. | Performance of durum wheat (Triticum durum) genotypes under variable sowing dates in sub-tropical zone of Jammu, Jammu & Kashmir
