STUDIES ON INTEGRATED NUTRIENT MANAGEMENT MODULE (INM) ON PHYSICO-CHEMICAL PARAMETERS OF GUAVA CV. LUCKNOW-49

Guava is the fourth important commercial fruit crop grown throughout India used mainly for fresh and processing purpose.Among the various factors which affect the production and productivity of guava, nutrient management assumes much more significance.The experiment entitled "Studies on integrated nutrient management module (INM) on physico-chemical parameters of guava cv.Lucknow-49 was conducted at Main Horticultural Research and Extension center (MHREC), University of Horticultural Sciences, Bagalkot.The experiment was laid out in RCBD design with 8 treatments replicated thrice.Among these treatments T 7 50 % RDF (150:60:75 g NPK/plant ) + 25 % through neem cake (1.5 kg/plant) + 25 % through vermicompost (2.5 kg/plant) + VAM (50 g/plant) + PSB (20 g/plant) + KSB (20 g/plant) + Azotobacter (20 g/plant) + micronutrients spray (Zinc sulphate @ 0.5 % + Boron @ 0.2 % + Manganese @ 0.1 %) was recorded maximum plant height (3.13, 3.37, 3.50 and 3.61 m), canopy volume (2.80, 3.22, 3.53 and 3.94 m 3 ), leaf area (37.26, 40.23, 43.26 and 48.27 cm 2 ), specific leaf area (57.32, 60.95, 64.57and 69.96 cm 2 /g) and chlorophyll content (19.36, 22.65, 26.25 and 29.47 SPAD).The same treatment was also favours the quality parameters such as maximum TSS (13.74 0 B), minimum acidity (0.44 %), TSS: acid (31.23), ascorbic acid (277.27mg/100g), pH (4.70), pectin (0.85 %), fruit firmness (49.44 N) and shelf life (7.25 days).
