dc.description.abstractAn experiment was conducted during 2014-15 on farmers field in Uttara Kannada district to know the effect of integrated nutrient management practices on early growth of young (2nd year) rubber (Hevea brasiliensis) plantation with three levels of farm yard manure (no FYM, 5 kg FYM/plant and 10 kg FYM/plant) and three levels of inorganic fertilizers (50:50:25; 100:100:50 and 150:150:75 g NPK/plant). Among the different levels of FYM, application of FYM @ 10 kg/plant has recorded significantly higher plant height (136.78 cm), collar diameter (30.54 mm), crown diameter (61.25 cm), number of leaves/plant (46.18) and number of whorls/plant (3.13). Among the different levels of inorganic fertilizers, application of NPK @ 150:150:75 g/plant has recorded significantly higher plant height (131.80 cm), collar diameter (30.31 mm), crown diameter (58.30 cm), number of leaves/plant (44.09) and number of whorls/plant (2.86). Among the interaction of organic manure and inorganic fertilizers, combination of FYM @ 10 kg/plant + NPK @ 150:150:75 g/plant recorded maximum plant height (143.42 cm), collar diameter (31.89 mm), crown diameter (64.05 mm), number of leaves/plant (47.62) and number of whorls/plant (3.33) compared to all other combinations. The soil properties viz., soil pH (5.30), electrical conductivity (0.32 dsm-1), organic carbon (0.57%), available nitrogen (156.1 kg/ha), phosphorus (8.87 kg/ha) and potassium (70.86 kg/ha) were also significantly higher with the application of FYM @ 10 kg/plant compared to other levels. Among the different levels of inorganic fertilizers, application of NPK @ 150:150:75 g/plant has recorded significantly higher electrical conductivity (0.25 dsm1), available nitrogen (152.5 kg/ha), phosphorus (8.74 kg/ha) and potassium (69.43 kg/ha). Among the interaction of organic manure and inorganic fertilizers, combination of FYM @ 10 kg/plant + NPK @ 150:150:75 g/plant recorded maximum pH (5.31), electrical conductivity (0.34 dsm-1), organic carbon (0.57 %), available nitrogen (159.6 kg/ha), phosphorus (9.13 kg/ha) and potassium (73.20 kg/ha).en_US
