Effect of Integrated Nutrient Management on Production and Economic Efficiency of Rice (Oryza sativa L.) under Upland Drilled Condition

A field experiment constituting four inorganic nutrient levels and six organic nutrient sources with 24 treatment combinations was conducted in split plot design with three replications during Kharif season of 2004, at Upland Paddy Research Scheme, MAU, Parbhani. The crop variety Parag was sown at 30 cm row spacing. The treatment S₄ - Recommended dose of fertilizer (80: 50: 50 kg NPK ha⁻¹) has recorded the significantly higher production and economic efficiency in case of inorganic nutrient levels. While Glyricidia @ 10 t ha⁻¹ recorded maximum production efficiency and gross monetary returns, but treatment S₃ biofertilizers (Azospirillum @ 1.5 kg + PSB 5 kg ha⁻¹) recorded higher net monetary returns and economic efficiency among organic sources. In case of interaction, treatment RDF + Glyricidia @ 10 t ha⁻¹ recorded significantly more grain yield, production efficiency and gross monetary returns, while treatment M₃S₃ - RDF + biofertilizers (Azospirillum @ 1.5 kg ha⁻¹ + PSB @ 5 kg ha⁻¹) recorded higher net monetary returns and economic efficiency.
