Abstract

Wheat is one of the important cereal crops in Nepal as well as globally. But due to varied climatic and sowing conditions low production has been reported throughout the world including Nepal. Sowing rates are highly correlated to yield and its yield attributing characters. Yield loss has been reported 50-62% under a late sown condition which shows a heavy threat to food security problems. Vijaya is the most recommended varieties under late sown conditions due to its high yield and less threat to late sown conditions. Thus identification and release of varieties suitable under late sown conditions are of the utmost importance. Researches should be accelerated under different agro-ecological zones to study the constraints associated with late sown wheat in Nepal.
