A Field experiment was conducted to evaluate the effect of different macro and micronutrients on soil and plant in cauliflower (Brassica oleracea var. botrytis L.) cv. Pusa Sharad at Research cum Instructional farm of Horticulture, Department of Vegetable Science, IGKV, Raipur during two consecutive seasons i.e., Rabi season 2017-18 and Rabi season 2018-19. The experiment was carried out under randomized block design consisting of fifteen treatments in three replicates. The important parameters encompassed in the study were available nitrogen (kg ha-1), phosphorus (kg ha-1), potassium (kg ha-1), boron (ppm), molybdenum (ppm) and zinc (ppm) content in soil and nitrogen (%), phosphorous (%), potassium (%), boron (ppm), molybdenum (ppm) and zinc content (ppm) in plants. All the treatments had a remarkable effect on the growth and yield of cauliflower, of which T5 (100% RDF + Borax @ 20 kg ha-1 + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1) had the most significant influence on all parameters under the study as compared to T1 (control). Micronutrient application can enhance the growth, curd maturity and curd yield of cauliflower.
