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. How to cite this article: Lupi A, Temteme S (2015).
