| Abstract | ||
| An experiment was conducted in rabia research centre to study the effect of inducing 0, 10, 20 Kg potassium fertilizer, 10 Kg potassium fertilizer plus 5 Kg Urea, 10 Kg potassium fertilizer plus 10 Kg Urea, 20 Kg potassium fertilizer plus 5 Kg Urea and 20 Kg potassium fertilizer plus 10 Kg Urea per donum on silty clay loam soil, on productivity and crop components, of chick pea variety (510). The result indicated that plant height, productivity per donum, number of horns, number of tillering and first horn height insignificantly increased with fertilizer application with 20 Kg potassium fertilizer+ 5Kg Urea per donum and then decreased because of competition between nutrients. The biomass was increased with fertilizer application with high levels which explained the latent deficiency of potassium. The potash fertilizer application to the chick pea varieties was an emergency task inspite of lab analysis which indicates that available K is high. Because of the high level of available phosphorus in rabia soil. The urea application with low soluble potash fertilizer to soils may resolve the problem of solubility by increasing the mass of root. | ||
