Abstract

 

The primary product of turmeric is the cured dried rhizome and its wide range of values such as coloring power in textile industry, medicinal values, for its appreciated aroma and flavor and foroleoresin. The yield of turmeric is directly related to soil nutrients status, either natural or enhanced. The N and P requirements are very high due to a long duration for maturity and high yielding nature of it. The experiment was conducted to study the rate of N and P fertilizers in south west Ethiopia. N was applied in the form of urea whereas P in form of TSP in four levels (0, 23, 46, 69) kg/ha and P (0, 10, 20, 30) kg/ha in RCBD factorial combined design in two cropping season using a Turmeric variety known as dame as a test spice crop. Analysis of the results revealed that plant length, rhizome weight and fresh rhizome of turmeric were significantly affected by the interaction of N and P. The application of 69kg N +10 kg P/ha was found to be most reliable and recommendable for turmeric production in south west Ethiopia. Further researchers has to be due attention on the time of application and nutrient use efficiency of turmeric.

Key words: Turmeric. Nitrogen, Phousphrous, Yield and yield component
