Effect of integrated nutrient management on growth and yield of pomegranate (Punica granatum L.)

Abstract

A field experiment was conducted on “Effect of Integrated Nutrient Management on Disease Resistance of Pomegranate (Punica granatum L.) Orchards” during 2017-18 and 2018-19 at College of Agriculture, Golegaon, VNMKV, Parbhani. The experiment was laid out in randomized block design with seven treatments i. e. T1- Absolute Control, T2- Farmer’s Practices (½ RDF), T3- RDF (625:250:250 g N, P2O5, K2O tree-1), T4- INM (15 kg FYM + 8 ml Azotobactor, 8 ml PSB, 100 g Trichoderma + RDF), T5- RDF + Antibiotics (Streptocycline @ 250 ppm), T6- T4 + Antibiotics, T7- T4 + Umber (Ficus racemosa) Rhizosphere Hybridised Soil (URHS @ 25 kg per tree) and four replications. The growth parameter, height of pomegranate plant at flowering and harvesting showed statistical significance with application of FYM @ 15 kg, Azotobacter @ 8 ml per tree, PSB@ 8 ml per tree and Trichoderma @ 100 g per tree, 625:250:250 g N, P2O5 and K2O per tree and 25 kg URHS per tree (T7) except treatment INM (FYM @ 15 kg + Azotobacter @ 8 ml per tree, PSB @ 8 ml per tree and Trichoderma @ 100 g per tree + 625:250:250 g N, P2O5 and K2O per tree)+ Antibiotics (Streptocycline @ 250 ppm per tree) (T6). It was ranged between 159.88 to 171.88 cm. The spread of pomegranate tree was not found significant with Integrated Nutrient Management practices (FYM, Solubilizers, RDF, Antibiotics and URHS). Yield attributes viz., number of flowers (204.75), number of fruits (172.88), fruit set (84.39%), fruit weight (244.82 g) and yield (41.21 kg tree-1) of pomegranate were significantly increased due to application of treatment T7 and found to be at par with treatment T6.
