dc.description.abstractAn experiment entitled to study the “A study on radiation and thermal use efficiency in barley genotypes (Hordeum vulgare L) under two row orientations” was conducted at the research station of Department of Agricultural Meteorology, CCS HAU, Hisar during 2004-05. Four barley varieties were sown under two row orientations i.e. north-south and east-west. Radiation and thermal use efficiency by was maximum in barley cultivar BH 393 followed by BH 338, BH 75 and DWR 28. Among the row orientations, barley crop sown in north-south direction shown the maximum radiation and thermal use efficiency as compared to east-west direction. Intercepted photoynhetically active radiation increase with crop growth and was maximum in cultivar BH 393 as compared to other cultivars, among row orientations, crop sown in north south direction shown maximum intercepted photoysnethically radiation as compared to east-west direction sown crop at all the phenophases. Grain number per spike, test weight and seed yield per plant was found to be more in barley cultivars BH 393 as compared to other cultivars. Among row orientations number of grains and seed yield per plant was higher in north-south direction sown crop. Biological yield, grain yield and harvest index was higher in cultivar BH 393 as compared to others and in row orientation, north south direction sown crop shown maximum biological yield, grain yield and harvest index as compared to east-west direction sown crop. A direct linear response was observed between crop parametersen_US
