“…Improved soil nutrition with the addition of manure results from microbial activity that breaks down organic matter into nutrients needed by plants. The use of compost, especially K, P, Zn, and N, can increase soil nutrient content so that the number and weight of tubers can increase (Yan et al, 2018;Showler, 2022).…”

Salinity is a major constraint for crop productivity as it reduces agricultural land area. This problem can be ameliorated by the application of organic materials such as manure, which plays an important role in supporting plant growth and reducing soil toxicity by binding toxic compounds. The purpose of this study is to analyse the effect of manure in overcoming the impact of salt stress on shallots. Here randomised block design (RBD) consisting of 2 factors and 3 replications was used. The first factor is salinity levels (0, 50, 100, and 150 mM), and the second is manure doses (0, 10 and 20 t•ha -1 ). This study finds that the application of 20 t•ha -1 of manure decreases the shallot's leaf tissue thickness, but the 50 mM of salinity significantly increases it. Then, the application of 20 t•ha -1 of manure increases the shallot's number of tillers and bulbs, while the 100 mM of salinity significantly decreases its number of tillers. The application of 10 t•ha -1 of manure decreases the proline and flavonoids content of the plant's leaves. In addition, plants treated and not treated with manure under 50 mM of salinity have higher proline and flavonoids levels in their leaf. Therefore, shallots can grow under salinity conditions if manure is applied.

Soil amended with rice straw compost significantly reduced rice sheath blight severity. The disease caused by the fungus Rhizoctonia solani Kühn is a severe disturbance to rice cultivation in Indonesia. R. solani is soil borne fungi and highly competitive as saprophyte. In mature compost, R. solani propagules in the form of sclerotia germination were suppressed by hyperparasites and other biological control agents. Compost maturity level affects the ability of sclerotia to germinate. Initial inoculum reduction as sclerotia in steril soil was studied in glass house which is treated with the addition of variations in the maturity of the compost. Result showed that mature compost added to sterile soil in the pot decreased sclerotia germination for about 14%, otherwise fresh organic matter added to steril soil increased sclerotia germination, this condition lead R. solani grew and new sclerotia formed in the soil surface. The decomposition levels of organic matter influences disease development, it significantly affected on disease severity. Disease severity of rice sheath blight decreased by about 32.6-39.9 % with mature compost application.

Burning sugarcane, Saccharum spp., fields to remove leaves before harvest is a routine practice in many sugarcane production areas, including the United States. The method is environmentally deleterious and has been discontinued in some parts of the world. Alternatively, excised preharvest leaf residue, or greenchop, is used as mulch. This field study examined the effects of greenchop, applied in several ways to sugarcane soil, on soil fertility, selected sugarcane plant physiochemicals, injury inflicted by the Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), and sugarcane yield parameters, compared to plots augmented by soil-incorporated compost and a nontreated control. The compost amended soil had elevated concentrations of many nutrients, and in sugarcane leaves, heightened concentrations of certain sugars and free amino acids. None of the greenchop treatments affected soil and sugarcane leaf nutrients. During the first year of the study, E. loftini injury to sugarcane stalks during the first season, however, was generally greater in the greenchop and compost treatments than in the control. In the second growing season, the compost treatment was the only treatment associated with heightened E. loftini infestations. Relationships between soils augmented with organic amendments and E. loftini injury to sugarcane are discussed in terms of mediation through physiochemical changes induced by the amendments.
