Studies on different levels of fertigation on growth and leaf nutrient status of pomegranate (Punica granatum L.) cv. Super Bhagwa

Abstract

The field trial was conducted on a well-established pomegranate orchard of four years age, spaced at 2.5 x 3 m2 at post- Gangapur, Taluka and District- Latur during 2016-2017, to study the different levels of fertigation on growth and leaf nutrient status of pomegranate (Punica granatum L.) cv. Super Bhagwa.The experiment was laid out in a Randomized Block Design with six treatmentsviz., T1 (Surface irrigation + R.D.F.-control), T2 (Drip irrigation + R.D.F.), T3(50% R.D.F. through fertigation), T4 (75% R.D.F. through fertigation), T5(100% R.D.F. through fertigation) and T6 (125% R.D.F. through fertigation)with four replications. The investigation indicated 100 % recommended dose of fertilizers through fertigation (T5) resulted, the highest net increasing plant height (0.28 m), plant spread (0.30 m), leaf nitrogen concentration at 55 days after bahar treatment (2.02 %) and final harvest (1.73 %) as compared to other treatments.Therefore, 100 % recommended dose of fertilizers through fertigation can be recommended for improve growth and leaf nutrient status of pomegranate cv. Super Bhagwa for four years old tree.
