To meet local and international demand for silk products, six (6) fertilizer management strategies involving green leaf manuring and silk waste composting were evaluated to improve mulberry leaf and silkworm cocoon yields and income at DMMMSU-Sericulture Research and Development Institute, Bacnotan, La Union, Philippines. The treatments were laid out in RCBD with three replications. Mulberry leaf and cocoon yields were gathered, analyzed using ANOVA and means were compared using HSD. Cost return analysis was estimated. Average single leaf weight was significantly higher in fertilized treatments than the control. Growing mulberries in May-July 2014 produced heavier mulberry leaf and biomass yield. Mulberry plants applied with ½ RRN + PK/ha + 5 tons silk waste + 10 tons Katurai leaves during May –July 2014 produced heavier leaf and biomass yields. The different fertilizer treatments did not significantly influence cocoon yields of silkworms. All fertilizer treatments significantly produced higher effective rearing rates and cocoon yield in November-December rearing seasons. The use of ¼ N + PK + 10 tons Katurai leaves + 5 tons silk wastes, and 10 tons Katurai leaves + 5 tons silk wastes alone are promising fertilizer management options to increase farm yields and income.
