Response of Integrated Nutrient Management on Quality Parameters of Broccoli (Brassica oleracea L. var. Italica) cv. Pusa KTS-1

Abstract

The present investigation was carried out to study the response of integrated nutrient management on quality parameters of broccoli (Brassica oleracea L. var. italica) CV. Pusa KTS-1. The field experiment was conducted at Horticultural Research Farm, Department of Horticulture, Ch. Charan Singh University Campus, Meerut (U.P) India, during the years 2019-20 and 2020-21. The experiment was laid out in Randomized Block Design. The treatments involved in the study were twelve in numbers i.e. T1 (Control), T2 (RDF 150:100:100 N.P.K), T3 (Azospirillum @ 5 kg), T4 (VC @ 10 t/ha), T5 (80% NPK + Azospirillum @ 1 kg), T6 (60% NPK + 2t/ha VC + Azospirillum @ 1 kg), T7 (60% NPK + Azospirillum @ 2 kg), T8 (60% NPK + 4 t/ha VC), T9 (40% NPK + Azospirillum @ 3 kg), T10 (30% NPK + 7t/ha VC), T11 (20% NPK + Azospirillum @ 4 kg), T12 (20% NPK + 8t/ha VC). The investigation indicated that a judicious combination of organic manures, inorganic fertilizers and biofertilizer i.e. 60% NPK + 2t/ha VC + Azospirillum @ 1 kg gave the maximum vitamin A (2452.07 IU) and protein content (3.53 %). Maximum vitamin C (98.28 mg/100g) was recorded under soil application of 60 % NPK + 4 t/ha Vermicompost which was found statistically at par with the treatments 60% NPK + Azospirillum @ 2 kg and 60% NPK + 2t/ha VC + Azospirillum @ 1 kg. However, the minimum vitamin A content (2369.24 IU), vitamin C value (51.79 mg/100g) and protein content (2.58 %) was observed under control treatment during two consecutive years of experimentation.
