Title: $The Study Integrated Nutrient Management on Growth, Yield and Yield Attributes of Carrot (Daucus Carota L.)
Abstract: The present investigation was planned and conducted at Department of Horticulture of Udai Pratap Autonomus College, Varanasi during the year 2014-15. To find out the response of various sources of integrated nutrient management on growth attributes with nine fallowing treatment viz. FYM @ 20ton/ha, vermicompost @ 4ton/ha, half FYM @ 10ton/ha + half vermicompost @2ton/ha, green leaf manure @ 5ton/ha + biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha, half FYM @ 10ton/ha + biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha, half recommended NPK + Half FYM @ 10ton/ha + biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha, half recommended NPK + green leaf manure @ 2.5ton/ha + biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha, half recommended NPK + half vermicompost @ 2ton/ha + biofertilizer i.e. Azotobacter and phosphobacteria each at 5 kg/ha, recommended dose NPK 80:60:60kg/ha respectively. The maximum height of plant at harvesting, length of leaves, number of leaves per plant and fresh weight of leaves were recorded in treatment T7 (1/2 recommended NPK + ½ green leaf manure + biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha) followed by the application of T9 (recommended dose of NPK @ 80:60:60kg/ha). The yield and yield attributes were significantly improved the various of integrated nutrient management. The maximum length of root, diameter of root, yield per plot (kg), yield per hectare (q) were recorded by the application of T7 (1/2 recommended dose of NPK + ½ Green leaf manure + Biofertilizer i.e. Azotobacter and Phosphobacteria each at 5kg/ha) followed by the application of T9 (Recommended dose of NPK @ 80:60:60kg/ha) besides, improvement in quality parameter were observed by the various sources of integrated nutrient management. The maximum TSS content were recorded by the application of T7 (1/2 recommended dose of NPK + Green leaf manure + Biofertilizer i.e. Azotobacter and phosphobacteria each at 5kg/ha). However, the TSS was statistically non- significant.
