Abstract: A field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi season 2016-17, consisting five levels of fertility and four levels of boron in randomized block design with three replications. Results revealed that different fertility levels influenced growth and yield of cauliflower significantly, chlorophyll content (1.36 mg/g), average weight of curd (386.56 g) and Volume of curd (261.27 cc) were recorded highest with application of 50% RDF through inorganic fertilizer and 50% RDF through vermicompost but remained at par with application of 25% RDF through inorganic fertilizers and 75% RDF through vermicompost. It is also revealed that fresh weight of plant at harvest (1.73 kg/plant) was recorded highest with application of 50% RDF through inorganic fertilizer and 50% RDF through vermicompost but remained at par with application of 75% RDF through inorganic fertilizers and 25% RDF through vermicompost and observed the day taken to curd initiation in cauliflower was found non-significantly with different fertility levels. However, curd formation was found earliest (62.49 days) in application of 25% RDF through inorganic fertilizers and 75% RDF through vermicompost. Similarly, the boron level with 2.5 kg per ha significantly increased the chlorophyll content (1.35 mg/g), fresh weight of plant at harvest (1.73 kg/plant), average weight of curd (375.51 g), Volume of curd (246.58 cc) and earliest curd initiation (62.45 days) as compared to control and 1.5 kg boron per ha but statistically at par with 2.0 kg boron per ha.
