Application of bokashi goat manure and organic liquid fertilizer to improve the growth and yield of Lembah Palu shallot variety

Abstract

The study aims to determine the effect of the application of solid organic fertilizers from bokashi goat manure (BGM) and liquid organic fertilizer (LOF) of cow urine to improve the growth and yield of ’lembah palu’ shallot varieties. The study was conducted on farmers’ land in Sidera Village Subdistrict Sigibiromaru Sigi Regency in Central Sulawesi. Research using Random Complete Block Design (RCBD) in factorials design (two-factor) with three replications. The first factor is the application of BGM, consists of 2 levels, namely: (1) without BGM and (2) BGM 30 t ha-1; The second factor is the concentration of LOF consists of 3 levels: (1) without the LOF, (2) LOF 16 L ha-1 and (3) LOF 32 L ha-1. The results of the research showed that BGM 30 t.ha-1, followed by application of 16 L.ha-1 LOF produce shallot crop is higher, and the number of tuber per hill and the fresh weight of tuber per hectare of shallot ’lembah palu’ variety is higher compared with a combination of other treatments. BGM 30 t.ha-1 produced more leaf number and fresh weight of tubers per plant higher and significantly different without BGM. Application LOF 32 L.ha-1 produce of shallot leaves more than without LOF and LOF 16 L.ha-1.

Yield Potential of Shallots Bulbil Planting Materials with Liquid Organic Fertilizer Treatment out of Season

“…This is because there is a slow mineralization rate in the use of organic fertilizers so that crop yields on land given organic fertilizers are lower than those shown chemical fertilizers [29]. Therefore, the application of organic fertilizers in the form of liquid organic fertilizers during the growing season has been evaluated [30][31][32]. Liquid organic fertilizer if used regularly, can increase the content of microbial carbon biomass, nitrogen, phosphate, and fungal ergosterol in the soil and CO2 production [33].…”

“…Combining chemical fertilizers with organic fertilizers is one of the effective fertilization efforts to increase crop yields and soil quality [15]. Several studies have been carried out that liquid organic fertilizer can support the growth and production of shallots [16][17][18][19][20]. Liquid organic fertilizer coconut husk waste dose of 1000 L ha -1 can increase plant height, number of leaves per plant, number of tillers, and yield of shallot bulbs [21].…”

Tropic soil properties and productivity of Shallot Lembah Palu variety

“…One of the famous superior commodities in the Palu Valley is the Palu Valley Variety Shallots. Shallots of the palu valley variety are the raw material of the fried shallot industry which is widely known by the public including those who visit the city of Palu both as local tourists and other guests [1][2][3] Shallots generally have wide adaptability and can grow and produce well to highlands in wet climates [4]. Unlike other IOP Publishing doi:10.1088/1755-1315/1253/1/012052 2 varieties of shallots, the Palu valley variety is found only in the Palu Valley and cannot adapt either in the midlands or in the highlands [2].…”

“…To overcome soil fertility problems related to less supportive soil properties, the combination of organic fertilizers and inorganic fertilizers used on a limited basis will strengthen each other, improving the physical, chemical properties of the soil and productivity [1,2,10,11]. Organic fertilizers in addition to being a source of plant nutrients can also increase the ability of the soil to bind water and plant nutrients through humus produced and can increase the activity of soil organisms, especially microbes that are heterotrophic as well as can increase fertilization efficiency [12].…”

Factores de interacción microbio-sustrato y gas-microbio en relación con la digestión anaeróbica del estiércol líquido y la productividad del cultivo

“…By so doing, it improves tilth, soil structure and amendments, cation exchange ability, plant growth and productivity, infiltration of water, and organic carbon content of the soil (that gives energy to soil microbes); prevents pest and disease attack; benefits socio-economically; and reduces runoff by acting as a mulch (BEL, 2005;Gajjela et al, 2018;Halder et al, 2018;Hoorman et al, 2009;Mahanta & Dhar, 2021;Maity et al, 2020;Msibi et al, 2014;Onduru et al, 1999;Supriya & Harish, 2019). LM are therefore, organic fertilizers formed by mixing and dissolving factory waste, crop residues, urine, green manures, sawdust, market waste, animal dung, household/kitchen waste, mushroom waste, agro-industrial wastes and farm residues, among othersby way of fermenting and/or decomposing them (Ansar et al, 2021;Elaiyaraju & Partha, 2016;Rana, n.d.;Supriya & Harish, 2019). In various farmlands, the efficiency of LM in growing certain types of crops compared to chemical fertilizers, has been studied with near 100% success by many researchers (Alamene & Howells, 2022;Antoneli et al, 2019;Arunkumar et al, 2021;Byeon et al, 2021;Choi et al, 2017;Gajjela et al, 2018;Msibi et al, 2014).…”
