Abstract:
Broccoli, one of the cool climate vegetables, is highly resistant to low temperatures and can be grown easily in areas with temperate climates. Nutrient management such as fertilization with nitrogen and micronutrients is an important practice to increase the yield and quality of broccoli. Therefore, the present study, “Impact of foliar application of different micronutrients morpho-physiological and yield traits of Broccoli (Brassica oleracea var. italica) F1 hybrid Shishir,” was carried out. for two consecutive years 2018-19 and 2019-20 during the Rabi season in polyhouse conditions at the Department of Plant Physiology, Agricultural Biochemistry, Medicinal and Aromatic Plants, College of Agriculture, Raipur, Chhattisgarh. The experiment was carried out following the Randomized Block Design with six replications and hybrid Shishir F1 was used as planting material. The treatment consisted of different concentration and combination of micronutrient viz., boron (B) and molybdenum (Mo) along with basal dose of fertilizers (RDF). During the study various phenological, morpho-physiological, yield and yield attributing traits were recorded and results showed that application of micronutrients significantly improve the growth, physiology, yield and yield-contributing traits of broccoli. The most promotive results were obtained with a combined application of B and Mo at 1.0% followed by B and Mo at 1.25% with 100% RDF. On the other hand, the highest SCMR values were recorded with the foliar application of B and Mo at 1.25% followed by B and Mo at 1.0% with 100% RDF; whereas yield-contributing traits and final curd yield were found highest with B and Mo at 0.75% in combination with basal dose of N, P and K at 100%.In conclusion, the identified concentrations of micronutrients could be used for the improvement of growth, physiology and yield of broccoli crop.
