Abstract:
An investigation was carried out to study the Effect of organic and inorganic fertilizers on broccoli (Brassica oleracea var. italica) cv- Palam Samridhi at vegetable research farm of Lovely Professional University, Phagwara, Punjab during winter season 2019-2020. The experiment was laid out at RBD (Randomized Block Design) with three replications and nine treatments having different combination of organic and inorganic fertilizer. Treatments used were: T₀ (Control), T₁-100% RDF through chemical fertilizer 125:62.5:62.5 kg NPK/ha, T₂-Vermicompost @2.5t/ha, T₃-Poultry manure @5.0t/ha, T₄-75% RDF through chemical fertilizer + vermicompost @0.3t/ha + poultry manure @0.63t/ha, T₅-50% RDF through chemical fertilizer + vermicompost @1.25t/ha + poultry manure @2.5t/ha, T₆- Poultry manure @5.0t/ha + Vermicompost @1.25t/ha, T₇-40% RDF through chemical fertilizer + vermicompost @0.75 t/ha + poultry manure @1.5t/ha, T₈- 60% RDF through chemical fertilizer + vermicompost @0.5t/ha + poultry manure @1 t/ha The experiment showed that inorganic fertilizer treatments i.e., T₁- 100% RDF i.e. N:P:K @125:62.5:62.5 kg/ha, was significantly superior over all the other treatments, recording maximum plant height (35.96cm), number of leaves/plant (15), leaf chlorophyll content (66.13mg/100g), weight of head (224.33g), yield/hectare (149.36 q/ha), total chlorophyll content (8.85mg/100g) of broccoli head, total soluble Solid (9.53⁰ Brix), ascorbic acid (224.33mg/100g), total cost of cultivation (1, 20, 600 Rs/ha), gross income (6, 72, 120 Rs/ha), net income (5, 51, 520 Rs/ha) and Benefit cost ratio (4.57).
