Efficiency of inoculation and different nitrogen fertilization on small-grained bean quality and yield

Influence of seed inoculation by nodule bacteria biopreparation Rhizobium l eguminosarum by. phaseoli and fertilization of 0, 20 and 60 kg N/ha on grai n yield, dry matter yield, thousand-grain weight, nodules dry weight, prote in content in above-ground weight of plants and grains as well as bean grai n concentration of phosphorus and potassium were observed on two soil types (meadow-loessive and cambisol; humogley) during three investigation years. The highest values with all investigated indicators were achieved in inocu lated variants. Influence of nitrogen fertilization depended on locality, i .e. chemical soil properties. Most of the investigated indicators obtained highest values at fertilization with 60 kg N/ha on meadow-loessive and camb isol soil where humus amounted to 1.78%. The highest values on humogley (hu mus content 2.25%) were achieved with fertilization of 20 kg N/ha.
