Examining the Strength and Direction of Association between Wheat Crop Productivity Status and Soil Nutrient Deficiency: A Non Parametric Analysis of Selected Districts of Punjab

Since crop productivity status of a given area is contingent upon the presence of soil nutrient deficiency, therefore the present study examines the strength and direction of association between wheat crop pro- ductivity status of districts of Punjab and soil nutrient deficiency using non parametric statistical measures of Pearson's chi-square, Cramer's V and Kendall's tau-b. The results validated the existence of significant moderate negative rela- tionship between wheat productivity status and the deficiencies of potassium, zinc and boron. The findings confirmed that low wheat productivity of a district is significantly related with presence of high amount of soil nutrient deficiency and vice versa, which reflects the presence of significant negative association between wheat productivity status of a district and soil nutrient deficiency. Both remedial and preventive agricultural measures should be undertaken so as to reduce and overcome soil nutrient deficiencies and achieve high wheat productivity status.
