Abstract: A survey was carried out in seven selected villages’ viz., Junnur, Seemikeri, Govinakoppa, Kaladagi, Sokanadagi, Chikkasamshi and Hiresamshi, located in and around Bagalkot Taluka, Bagalkot district, Karnataka during the hasta bahar season of 2017-18. The orchards were categorized based on their yield levels into low yielding (LYO) and high yielding (HYO) orchards considering Karnataka state average productivity of 11.71 t ha -1. Twenty three orchards having mean yield of 9.91 t ha-1 (Range: 7.81-11.32 t ha-1) were grouped under LYO and one hundred and twenty seven orchards were grouped under high yielding orchards with mean yield of 18.12 t ha-1(Range: 12.32-25.63 t ha-1).The average fruit yield (28.9 kg plant-1), average fruit weight (389.7 g fruit-1) and number of fruits (74) were significantly higher in HYO as compared to LYO. The soil status indicated significantly higher content of organic carbon, DTPA Zn and DTPA Fe in HYO as compared to LYO, while soil pH, EC, DTPA Cu and DTPA Mn were on par in both the categories. The HYO showed significantly higher content of Zn, Fe & Mn in pomegranate leaf, whereas Cu content was higher in low yielding orchards. The optimum leaf micro nutrient range was developed for obtaining higher pomegranate productivity and the values were in the range of 28-41, 20-43, 138-213 & 54-75 mg kg -1 respectively for Zn, Cu, Fe and Mn. The correlation studies indicated negative relationship for pomegranate productivity with soil pH, EC, DTPA Cu and leaf Cu content while, soil OC, Zn, Fe and Mn content both in soil and leaf showed positive correlation.
