Growth, Yield and Quality of Turmeric (Curcuma longaL.) Cultivated on Dark-red Soil, Gray Soil and Red Soil in Okinawa, Japan

Effects of Farmyard Manure On Growth and Yield of Turmeric (Curcuma LongaL.) Cultivated in Dark-Red Soil, Red Soil andgray Soil in Okinawa, Japan

“…The plants with the manure remained green longer and had higher plant height, larger leaf area and greater leaf biomass (Table 3), which ultimately provided longer and higher photosynthesis process and resulted in a higher yield of turmeric. Similar results were obtained in previous studies (Sarker et al, 2001;Ishimine et al, 2003Ishimine et al, , 2004Hossain et al, 2005a, b;Hossain and Ishimine, 2005). 4.0 ± 0.9a 13971 ± 1223a 66.9 ± 1.8a…”

“…Turmeric is commercially cultivated in dark-red soil (Shimahiri maaji), red soil (Kunigami maaji) and gray soil (Jagaru) in Okinawa (Hossain and Ishimine, 2005). Previously, we evaluated planting depth, time, pattern, seed size and soil types on growth and yield of turmeric (Ishimine et al, 2003(Ishimine et al, , 2004Hossain et al, 2005a, b;Hossain and Ishimine, 2005). Here, we evaluated the effects of farmyard manure on growth and yield of turmeric cultivated in dark-red soil, red soil and gray soil.…”

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

“…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).…”

Study on growth characteristics of a plant species in local soils is important to develop management practices for higher yield with good quality (Hossain & Ishimine, 2005).…”

“…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].…”
