Abstract:

A field experiment was conducted to assess the precision management practices on agronomic efficiency, grain yield, water productivity and economics of aerobic rice during summer 2016 and kharif 2016. Treatments comprising two nutrient management practices, three planting geometry and two water management practices with one control (soil application of fertilizer dose and drip irrigation) and one absolute control (No RDF and drip irrigation). The results revealed that, among interactions between nutrient management, planting geometry and water management, application of 25% N&K from sowing to 30 DAS + 25% N&K from 31 to 50 DAS + 25% N&K from 51 to 80 DAS + 25% N&K from 81 to 105 DAS with planting geometry of 25×15 cm and drip irrigation scheduling at 125% PE up to tillering + 150% PE from tillering to PI + 200% PE from PI to physiological maturity recorded significant grain yield (8.56 t ha-1), agronomic efficiency of nitrogen, phosphorus & potassium (62.87, 125.74 and 125.74 kg kg-1, respectively) and net returns & B:C ratio (₹ 82,853 and 2.47, respectively) than soil application of fertilizers in aerobic rice.
