Abstract

In a sustainable agriculture system, closed organic materials could help utilize local resources and improve farming efficiency. The purpose of this study was to utilize nearby materials with a high decomposition rate, allowing for the incorporation of well‐known residues. Specifically, Tithonia diversifolia and Alnus acuminata biomass were targeted as materials to be mixed with farmyard manure. Different rates of T. diversifolia and A. acuminata biomass + farmyard manure compost materials were assessed with the application of NPK in all the treatments, with two levels of lime (0 and 1.5 t/ha). The compost made by T. diversifolia + farmyard manure increased the dry matter and yield of Irish potato and maize, and lime has contributed to dry matter and yield production. The application of 5 t/ha of manure did not affect much the dry matter yield. 10 t, 15 t, 20 t, 25 t, and 30 t significantly produced good dry biomass compared to the control, but manure rates above 5 t/ha gave similar yields, except for 25 t/ha, which was distinctly higher. Lime application significantly increased the dry matter yield from 3.4 to 3.8 t/ha. All the rates significantly responded well compared to the control on tuber parameters, and the five levels (10 t, 15 t, 20 t, 25 t, and 30 t) with lime belatedly indicated a significant difference with the rate of 5 t/ha on the yield. Both closed biomass sources, farmyard manure from animals, demonstrated strong potential as effective composting materials.
