Response of foliar application of cow-urine and nitrogen fixing bacterial inoculants on quality of cauliflower (Brassica oleracea L. var. botrytis) cv. White crystal grown under naturally ventilated polyhouse condition

Abstract

The present investigation “Response of Foliar Application of Cow-urine and Nitrogen Fixing Bacterial Inoculants on Quality of Cauliflower (Brassica oleracea L. var. botrytis) cv. White Crystal Grown under Naturally Ventilated Polyhouse Condition” was carried out in the poly-house at the Centre of Excellence on Protected Cultivation and Precision Farming (COEPCPF), IGKV, Raipur, (Chhattisgarh) during the academic years 2022-2023 and 2023-2024 in Rabi season. The experiment was laid out in completely randomized design (CRD) in three replications with nine treatments. The results of the present study showed that the quality parameters such as chlorophyll content in leaves (60.26), nitrogen content in leaves (2.23%), vitamin C (60.02 mg /100 g), β- carotene content (13.02 μg/100 g), vitamin A content (21.70 μg/100 g), protein content (15.33%), nitrogen content (2.46 %), phosphorus content (0.26%), potassium content (3.38%), reducing sugar (2.10 %), non-reducing sugar (0.24 %), total sugar (2.35%) and total soluble solids (7.83%) in curd were found superior in treatment T9 - Foliar application of foliar Azotobacter and foliar Azospirillum + FS of 10% Cow-urine + 0.1 % Molasses.
