Nutrient Uptake and Yield of Chinese Cabbage (Brassica rapa L. Chinensis) Increased with Application of Macadamia Husk Compost

There is a dearth of information on the effect macadamia husk compost (MHC) productivity short-season, shallow-rooted annual crops. We assessed response yield and nutrient uptake Chinese cabbage (Brassica rapa L. Chinensis) to MHC application. The treatments (zero control, inorganic fertilizer (100:60:60 kg NPK ha−1), 15 30 t ha−1 MHC) were arranged in randomized complete block design replicated three times. Number leaves, leaf area index, biomass, concentration (N, P, K, Ca, Mg, Zn, Cu, Mn, B) determined at 28, 46, 74 days after transplanting (DAT), root length biomass DAT. Inorganic increased with greater increases recorded higher rates. application (28 DAT) (74 suggesting that organic soil amendments more pronounced over long run compared fertilizers. macronutrients fertilizer. Clearly, may be beneficial improving loamy sand soil, but varies time harvesting.
