Growth, yield and forage quality influence of intecropping and fertilization schemes on adlay (Coix lacryma-jobi L.) ratoon

Adlay has the potential in improving the production of livestock in the Philippines as it can be utilized both as a grain and forage crop. The study was conducted to evaluate the growth, yield and forage quality of adlay ratoon at various intercropping and fertilization schemes. It was laid out in split-plot arranged in RCBD with three mainplots and five subplots replicated four times. The intercropping scheme did not significantly influence the parameters gathered. However, the fertilization scheme significantly influenced the height, number of tillers hill-1, fresh herbage yield and dry matter yield of adlay ratoon. Application of 120 kg N ha-1 resulted in significantly better effect on the aforementioned parameters compared to without fertilization and application of 2 t ha-1 chicken dung but at par with the rest of the fertilized treatments. As to forage quality, adlay ratoons with napier at 1:1 ratio had the least percentage of crude protein (CP), acid detergent fiber (ADF) and acid insoluble ash (AIA) but with highest dry matter (DM). Ratoons applied with 120 kg N ha-1 had the highest and lowest percentage of CP and DM, respectively, among fertilization scheme while the unfertilized ones had the least percentage of ADF and AIA.
