In the present study, single factor analysis of variance (one-way ANOVA) was employed to study the relationship between wheat crop productivity and soil macro nutrient levels across areas with varying levels of wheat crop productivity in Punjab. The overall average values of both nitrogen (47.11 kg/ha) and potassium (64.62 kg/ha) were observed to be much below the critical limit of 280 kg/ha and 108kg/ha, respectively prescribed by the Indian Ministry of Agriculture. This is reflective of the existence of deficiency of these two macro soil nutrients in the state of Punjab. Further, as per the results of Scheffe post hoc multiple comparison test, the mean values of two macro soil nutrients (nitrogen and potassium) in the low wheat productivity area was observed to be significantly less than that of the high wheat yield area, which reflected that as we move from low to high wheat yield areas, the average values of these soil nutrients display an increasing trend. Thus, there appeared to be a negative relation between levels of macro soil nutrients and wheat productivity levels across selected areas of Punjab.
