Effect of organic and inorganic sources of nutrients on growth, yield and economics of Indian mustard (Brassica campestris L.)

Abstract

A field experiment was conducted during Rabi season of 2024-25 at Instructional cum Research Farm, SG College of Agriculture and Research Station, Jagdalpur, to evaluate the Effect of organic and inorganic sources of nutrients on growth, yield and economics of Indian mustard (Brassica campestris L.). The experiment was laid out in Randomized Block Design with 8 treatments viz., RDF 100:60:40:35 NPKS kg ha-1, RDF + FYM 10 t ha-1, RDF 75%, RDF 75% + FYM 10 t ha-1, RDF 50%, RDF 50% + FYM 10 t ha-1, FYM 10 t ha-1, Control replicated thrice. Increase in the application of varying organic and inorganic nutrient sources exhibited a significant influence on all growth parameters significantly the highest growth characteristics viz., Number of branches (25.10 plant-1), leaf area index (10.93) and Days to maturity (99 days), yield attribute and yield included No. of siliqua (155.16 plant-1), grain yield (18.00 q ha-1) reported under recorded under RDF + FYM @ 10 t ha-¹ combination and economics indicated the B:C ratio (2.80) recorded under RDF 100:60:40:35 NPKS kg ha-1 treatment.
