EFFECT OF THE COMBINED APPLICATION OF MANURE COMPOST AND Trichoderma sp. ON PRODUCTION PARAMETERS AND STEM ROT DISEASE INCIDENCE OF SHALLOT

Abstract

Manure compost is a type of organic fertilizer derived from animal feces. Even though compost has a slow-release nature, it can be a good alternative to chemical fertilizers. The addition of Trichoderma sp. as a decomposer microorganism can accelerate nutrient availability. The objective of this study was to determine the effect of the combined application of different types of manure compost and doses of Trichoderma sp. on the growth performance, yield as well as stem rot disease incidence of shallot (Allium cepa L. var. aggregatum). The study was carried out using a split-plot design (P 0.05) with the types of manure compost as the main plot with five levels (no compost, cattle manure, chicken manure, goat manure, and petrogenic compost), and different doses of Trichoderma as subplots with three levels (no Trichoderma, 200 kg ha-1, and 400 kg ha-1). In general, the combined application of manure compost and Trichoderma significantly increased growth performance and yield of shallot compared to no compost (B0) and Trichoderma (T0). However, no differences were observed between manure compost and the addition of Trichoderma. Growth performance of shallots grown in soil amended with cattle manure compost was better compared to the other treatments. The use of 5 t ha-1 cattle manure compost combined with 400 kg ha-1 Trichoderma increased yield by 10.02 t ha-1 and reduced stem rot diseases incidence by 0.67%.

Increasing shallot yields by using solid organic fertilizer and liquid organic fertilizer on dryland

“…The use of inorganic fertilizers can pollute the soil, lower the soil pH, damage the microorganisms in the soil, quickly absorb nutrients, causing the soil to be poor in nutrients, and reduce plant resistance to pests and disease ( [3,4]. Efforts that can be made to overcome the negative impacts of using inorganic fertilizers are by using organic fertilizers such as compost, biological fertilizer and liquid organic fertilizer [5].…”

Effect of concentration of banana corm liquid organic fertilizer and dosage of bokashi fertilizer on growth and yield of long bean (Vigna sinensis L.)

“…To reduce the impact of using inorganic fertilizers, this can be done through the continuous use of solid organic fertilizers and complete liquid organic fertilizers according to recommendations. Solid organic fertilizer, with the application of manure which has a high organic matter content thereby increasing the soil's ability to bind water and various nutrients, as well as increasing the diversity of microorganisms in the soil which can help increase plant growth [4]. In addition to solid organic fertilizers, the application of banana corm liquid organic fertilizer has a role in the vegetative growth period of plants and plants tolerant to disease, high levels of phenolic acids help bind Al, Fe and Ca ions thus helping the availability of soil Phosphorus (P).…”
