Coix Lacryma-Jobi L. Nutritional Value Concerning Nitrogen Fertilizer Doses

Coix lacryma-jobi L., as animal feed is considered a cereal plant from the Poaceae or Gramineae family.We aimed to determine the influence of different doses of Nitrogen (N) fertilizer on Coix lacrymajobi L. It was conducted in the Lempake Village area; and the Chemical and biochemical laboratory of agricultural products and animal husbandry nutrition laboratory at Mulawarman University from March to September 2021.Data were collected using a randomized block design and five treatments as follows T0 = control, T1= 150 kg/ha, T2= 300 kg/ha, T3= 450 kg/ha, and T4= 600 kg/ha with four replications.The results showed a significant effect on Dry Weight (DW) and Moisture Contents (MC) of Coix lacryma-jobi L., with no significant (p<0.01)effect on Dry Matter (DM) and Crude Fiber (CF).The application of different doses of N fertilizer led to a high Crude Protein (CP) and ash contents but failed to affect the crude fat and Nitrogen Free Extract (NFE).The best nutrient contents were observed at 600 kg/ha, with CF, CP, Ether Extract (EE), ash, and NFE at 24.34, 8.50, 1.49, 11.63, and 54.04%, respectively.
