Impact of integrated nutrient management on the economic cultivation of turmeric (Curcuma longa L.) in an Acid Alfisol of Himachal Pradesh

The productivity of turmeric in Himachal Pradesh (0.70t ha⁻¹) is still below the India average (4.95 t ha⁻¹). The main reason for low productivity is that these crops are largely cultivated under nutrients starved conditions. Keeping this fact in view, field experiment were conducted during kharif seasons on turmeric (Curcuma longa L.) variety T-12 at research farm of Department of Soil Science CSK HPKV, Palampur (HP) on silty clay loam soil with eleven treatments including a control. The pooled results of two years showed that highest mean yield (150.8q ha⁻¹), highest income over control (50,382 ha⁻¹) and highest net returns (63,566 ha⁻¹) were recorded in the treatment, 100% NPKS + 20t FYM ha⁻¹ as soil mulch. Whereas, highest benefit cost ratio (1:2.99) was recorded in treatment 100% NPKS.
