Abstract:
The present investigation "Study on the effect of application of chemical fertilizers, organic manures and bio-inoculants on growth parameters of cauliflower" during rabi season of 2019-20. Fourteen treatments of different combinations were applied in the experiments. The plant growth parameters observed at three time periods under 30, 45 and 60 DAT included plant height (cm) (25.67, 34.57 and 42.87), number of leaves (10.04, 15.78 and 17.81), leaf length (cm) (15.27, 21.23 and 27.78), leaf width (cm) (9.86, 12.40, 13.85) was recorded maximum in the treatment T₂ RDF (NPK 100:80:80) respectively. Maximum petiole diameter (1.51) per plant was recorded at 60 DAT in T₂ treatment RDF (NPK 100:80:80) and in the practice of farmers at the beginning of the first curd T₁₄ (F.Y.M @ 1 ton/ha + Urea + D.A.P (about 100:40) (48.487) was found. Maximum diameter of curd (17.58), stalk diameter per plant (1.51) at 60 DAT was recorded in the treatment T₂: R.D.F (NPK 100:80:80 kg/ha.). The 50 percent curd initiation of Cauliflower per plant (64.97) at DAT was recorded in the treatment T₁₄. Direct relation to different growth stage of cauliflower. Application of T₂ RDF (NPK 100:80:80) proved to be the next best treatment.
