Effects of Application of N, P And K Alone Or In Combination on Growth, Yield And Curcumin Content of Turmeric(Curcuma LongaL.)

Effects of soil types and fertilizers on growth, yield, and quality of edibleAmaranthus tricolor linesin Okinawa, Japan

“…Similarly, several studies reported that N is more significant than other nutrients for vegetative growth of plants (Akamine et al, 2007;Chowdhury et al, 2008;Hossain et al, 2011Hossain et al, , 2012Sarker et al, 2002). In addition, higher K, P, N, and pH, and lower Na probably made better combination in gray soil for better growth of amaranths, as compared to those in other soils (Table 1 and Figure 2).…”

“…Growth, yield, and quality of a plant species differ with soil types, soil nutrient status, and fertilizer management; and a plant species requires suitable soil for higher yield and better quality (Akamine et al, 2007;Chowdhury et al, 2008;Hossain & Ishimine, 2005;Hossain et al, 2011;Islam et al, 2011;Oya, 1972;Oya et al, 1977). Soil fertility and crop productivity differ significantly with the amount and combination of Na, K, Ca, Mg, S. P, Fe, Al, pH, and N in soil (Broadley et al, 2012a(Broadley et al, , 2012bHawkesford et al, 2012;Oya, 1972).…”

“…Different plant species respond differently to fertilizer rates and combination and a plant species requires balanced fertilizers to maximize growth, yield, and quality (Akamine et al, 2007;Chowdhury et al, 2008;Hafsi et al, 2011;Hossain et al, 2004). The major nutrients (N, P, K) individually or in combination maintain growth, yield, and quality of plants (Hafsi et al, 2011;Ivonyi et al, 1997;Mazid, 1993;Nakano & Morita, 2009).…”

“…Insufficient K causes shoot yellowing, poor growth, and low resistance to cold and drought of plant (Oya, 1972). Phosphorus promotes absorption of other nutrients and plant growth (Akamine et al, 2007).…”

“…The medicinal value of turmeric is associated with the yellow color pigment "curcumin" (diferuloyol methane) content in it. Curcumin content varies in the range of 0.3% to 8.6% [47,[51][52][53][54], due to nutrients and acidity content in soil [55,56], fertilizer, soil type and cultivar [57][58][59]. Due to the isolation of curcumin from turmeric for medicinal and cosmetic purposes, it is adulterated with color dyes as a substitute for curcumin [60].…”
