Performance of Gobhi Sarson (Brassica napus L.) under Integrated Nutrient Management

Abstract

A field experiment was conducted during rabi season (2023-24) at Agricultural Research Farm, School of Agricultural Sciences and Technology, RIMT University Mandi Gobindgarh, to study the effect of integrated nutrient management (INM) in Gobhi Sarson (Brassica napus L.). The experimental field was laid out in randomized complete block design with 10 treatments and replicated thrice. The experiment comprised of 10 treatments i.e. T1 -Control, T2 -100% Recommended Dose of Fertilizers (RDF) (40:20::N:P2O5 kg ha-1), T3 -125% RDF, T4 -150% RDF, T5 -50% RDF + 15 t Farm Yard Manure (FYM) ha-1, T6 -50% RDF + 20 t FYM ha-1, T7 -75% RDF + 15 t FYM ha-1, T8 -75% RDF + 20 t FYM ha-1, T9 -100% RDF + 15 t FYM ha-1 and T10 -100% RDF + 20 t FYM ha-1. The result revealed that growth parameters were significantly higher in treatment T10 -100% RDF + 20 t FYM ha-1 plant population (21.79 m-2), plant height (157.9 cm), number of branches plant-1 (17.15), chlorophyll content (55.74) and yield and yield attributes were also significantly higher in treatment T10 -100% RDF + 20 t FYM  number of siliquae plant-1 (291.0), siliqua length (8.423 cm), number of seeds siliqua-1 (23.01), 1000 seed weight (3.45 g), seed yield (23.45 q ha-1), straw yield (59.04 q ha-1) and harvest index (28.80 %) were observed. From this study it may be concluded that the combination of RDF and FYM enhanced the overall growth, yield and yield attributes of Gobhi Sarson.
