Turmeric (Curcuma long L.) is an important cash crop spice commonly known as ‘Ird’ in Ethiopia. However, the decline in nutrients is one of the bottlenecks in spice production in Ethiopia as a general. Among those turmeric is one of the cash crops which need enough fertilizer application for its growth and boosting yield. The field experiment was conducted to evaluate the effectiveness of NPS fertilizer during the 2018 and 2019 main cropping seasons. The treatments were laid out in a randomized complete block design with three replications. Treatments were consisting of the two checks (control and recommended NP fertilizer) and nine different rates of NPS fertilizer at the rate of 100, 150, and 200, each of them combined with three different N fertilizer rates of 150, 200, and 250 kg ha-1. Turmeric yield and yield components of turmeric were subjected to statistical analysis using SAS; the mean treatment difference was compared using LSD. The analysis of variance showed the yield and yield components of turmeric were none significantly (p>0.05) influenced by NPS fertilizer application as compared with the recommended NP fertilizer, but it was significantly (p<0.05) influenced when compared with the control treatment. The highest fresh rhizome yield (41.92 tonne per hector) was obtained from the application of recommended NP fertilizer. The application of recommended NP (150 urea with 50 TSP) kg ha-1 showed economically better than the NPS fertilizer for turmeric production, following the recommended NP fertilizer the NPS fertilizer at the rate of 100 NPS kg ha-1 with a high dose of nitrogen (250urea) kg ha-1 as the second alternative for turmeric crop production. The result indicates that NPS which site-specific recommendations reformed was note better than the recommended NP fertilizer in agronomic and economic sense at Yeki District.
