Performance of Onion Seed Crop under the Soil Amendments and Fertilizers Application in Torripsamments

Sandy soils cover approximately 900 million ha worldwide particularly in arid and semi-arid regions. There are extensive areas of sandy soils under cultivation, but the soil fertility is often low and dependent on management practices for crop production so better management sandy soil conducted a field experiment at Aagricultural Research Station, Farm, SKRAU, Bikaner during Rabi 2021-22. The experiment was laid out in a split plot design involving four soil amendments i.e., Control, 2 % canal silt, compost @ 30 t ha-1 and 2 % canal silt plus ccompost @ 30 t ha-1 in main plot and four fertilizer levels i.e., 0, 75, 100 and 125 % RDF in the sub plot with three replications for onion seed producion. The results revealed that application of different soil amendments significantly increased onion growth and yield attributes and found that maximum growth and yield attributes were recorded under 2 % canal silt with compost @ 30 t ha-1. It was also observed that as the RDF increases, growth, yield, yield attributes, of onion during the onion seed crop production.
