A survey study was conducted in one hundred and fifty pomegranate orchards situated in seven villages of Bagalkot district, Karnataka viz., Junnur, Seemikeri, Govinakoppa, Kaladagi, Sokanadagi, Chikkasamshi and Hiresamshi to assess the soil and plant major mineral nutrient concentration and its relation with pomegranate yield. The orchards cultivating Bhagwa variety of 3-7 years old and fruiting season during hasta bahar 2017-18 were surveyed and categorized into low (LYO) and high yielding orchards (HYO) based on their yield levels by considering the Karnataka state average productivity i.e. 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), fruit weight (389.7 g fruit-1) and number of fruits (74) were significantly higher in HYO as compared to LYO. Application of higher amount of organic manure and major nutrients through inorganic fertilizer was noticed in HYO as compared to LYO. However, the time of nutrient application varied greatly among the two categories. Relatively higher rate of N and P application at bahar initiation stage and very low nutrient application was noticed at rest period in LYO. The soil and leaf status of pomegranate orchards separated based on their yield levels revealed that the nitrogen content both in soil and leaf was significantly higher in LYO as compared to HYO. Hence, negative correlation was observed between pomegranate yield and N content both in soil (-0.539) and leaf (-0.471) at flowering stage. But, the Phosphorus and Potassium content were significantly higher in HYO as compared to LYO indicating positive correlation with pomegranate yield.
