Effect of integrated nutrient management on quality and yield parameters of guava (Psidium guajava L.) cv. l-49

Abstract

An investigation entitled “Effect of Integrated Nutrient Management on quality and yield parameters of Guava (Psidium guajava L.) cv. L-49” was carried out at the Instructional cum research fruit orchard, College of Horticulture, Mandsaur, during 2015-16. The present result revealed that the application of 100 % NPK + 5 kg vermicompost + 150 gm Azatobactor (T6) recorded minimum acidity (0.23 %) and maximum TSS (12.67 0Brix), TSS/acid ratio (56.39), ascorbic acid (206.07 mg/100g pulp), pectin (0.75 %), total sugars (8.21 %), reducing sugars (4.15 %) and non-reducing sugars (4.06 %). Whereas, the maximum number of fruits per tree (286.91), fruit weight (209.88 g) and yield per tree (60.20 kg) were recorded with the application of 100 % NPK+ 5 kg vermicompost + 150 gm VAM (T8).
