Performance of wheat (Triticum aestivum) varieties in Eucalyptus plantation

A field experiment was conducted for 2 crop seasons (1999–2000 and 2000–2001) at Hisar, Haryana, to study the performance of wheat (Triticum aestivum L. emend. Fiori & Paol.) genotypes in association with Eucalyptus plantation. Among the yield attributes, the effect of shade was maximum on effective tillers and was minimum on test weight. The yield attributes and grain yield of wheat decreased significantly with successive increase in shade level from S₂₄ to S₆ during both the years except effective tillers/plant and test weight between S₁₂ and S₁₈. The quantum of decrease in grain yield with increased shade from S₆ to S₁₈ over S₂₄ was 49.2%, 29.1%, 13.1% respectively. Among the varieties, ‘PBW 343’ yielded highest followed by ‘PBW 175’. The yield reduction was least in ‘IWP 72’.
