Utilization of rabbit manure and biochar chicken manure and its effect on the growth and yield of pakchoy plants

Abstract

This study aims to determine the effect of rabbit manure, biochar from chicken manure, and its interactions on the growth and yield of pakchoy plants. This study uses a randomized block design (RBD) with factorial patterns (2 factors). The first factor is the dose of rabbit manure which consists of 4 levels (0, 10, 20, and 30 tons ha-1). The second factor is the biochar dose of chicken manure consisting of 4 levels (0, 5, 10, and 15 tons ha-1). The results showed that the treatment of biochar dose of chicken manure and the treatment of interactions between the dose of rabbit manure and the biochar dose of chicken manure had no significant effect on all observed variables. The treatment of rabbit droppings did not significantly affect all observed variables, except that the fresh weight of the roots showed a real effect. Fresh weight of economic results in the application of rabbit manure 30 tons ha-1, gives a higher yield or an increase of 17.08% when compared to without rabbit manure. While the fresh weight of economic results on the application of biochar from chicken manure 30 tons ha-1 gave higher yields or increased by 23.86% compared to without biochar.
