Abstract
Root development of wheat (Triticum aeslivlrm L. emend. Fiori & Pool.) and barely (Hordeurn vulgure L. sensu lato) and its consequent effect on moisture use, yield and moisture-use efficiency under the influence of varieties and nitrogen levels was studied at Kanpur, during 1986-87 and 1987-88 under moisture-scarce conditions on light-textured alluvium soil. In wheat, except root depth, variety K 78 showed better root development, higher moisture extraction, yield and nloisture- use efficiency than the other varieties. In barley, best developnlent of roots in respect of depth, number of primary roots, moisture use, yield and moisture-use efficiency was observed in variety Lakhan. Application of N @ 60 kgha resulted in the maximum root expansion, moisture use, moisture-use efficiency and yield of wheat and barely compared with that obtained with 0,20 and 40 kg Nha.References

Root development of wheat (Triticum aeslivlrm L. emend. Fiori & Pool.) and barely (Hordeurn vulgure L. sensu lato) and its consequent effect on moisture use, yield and moisture-use efficiency under the influence of varieties and nitrogen levels was studied at Kanpur, during 1986-87 and 1987-88 under moisture-scarce conditions on light-textured alluvium soil. In wheat, except root depth, variety 'K 78' showed better root development, higher moisture extraction, yield and nloisture- use efficiency than the other varieties. In barley, best developnlent of roots in respect of depth, number of primary roots, moisture use, yield and moisture-use efficiency was observed in variety 'Lakhan'. Application of N @ 60 kgha resulted in the maximum root expansion, moisture use, moisture-use efficiency and yield of wheat and barely compared with that obtained with 0,20and 40 kg Nha.
Barley (Hordeum vulgare L. sensu lato) and wheat (Triticum aestivum L. emend. Fiori & Paol.) are grown under semi-irrigated conditions, which may suffer due to deficiency of water at critical stage of growth and development. Adequate fertilization and choice of a good variety
