Abstract:
A field trial was carried out at Vegetable Research Centre (VRC) of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India during September to February 2021-22 and 2022-23 to find out the Influence of NPK on growth, yield and nutrient content broccoli (Brassica oleracea L. var. italica) under drip and conventional irrigation system. The experiment that uses a two factorial randomized block design (RBD) with eight treatments under two irrigation methods (drip and conventional method). T₁ consist of 100 percent of RDF NPK similarly, T₂ consist of 100 percent of RDF N₀PK, T₃ consist of 100 percent of RDF NP₀K, T₄ consist of 100 percent of RDF NPK₀, T₅ consist of 100 percent of RDF of N₀P₀K, T₆ consist of 100 percent of RDF N₀PK₀, T₇ consist of 100 percent of RDF of NP₀K₀ and T₈ control under both drip and conventional method of irrigation and replicated thrice. The outcome of the present study revealed that broccoli performance was significantly influenced under drip fertigation. Pooled data revealed that highest observation was recorded in terms of growth parameters i.e., plant height at 30, 45 and 60 days after transplanting (DAT) was recorded (53.83, 77.02 and 82.55 cm), number of leaves (18.45, 26.67 and 34.33), yield parameter i.e., total yield per hectare (163.12 q/ha) and head weight (500.94 g) and nutrient content in broccoli head i.e., nitrogen content (3.15 %), phosphorus content (0.68%) and potassium content (2.26 %) under drip fertigation. Highest observation was recorded in T₁ (fertigation with 100% RDF of NPK) in all the parameters as compared to other treatments. The outcome of the study was that fertigation of 100 percent RDF of NPK (120:60:60 kg ha^-1) was best treatment for broccoli.
